Small tip for DIY-people: If you don't like the safety pin used on the Deore Calipers you can retrofit the screw from the higher series if you tap the threads into the calipers. Remove the pin, tap on the outside latch, I believe its a M4 thread. Then just screw in the screw and secure with the clip. Done!
@@ryansteiger6960 absolutely none ....when you've bought the screw pin just use the screw as your tap .....its strong and cuts absolutely perfect threads into the caliper with only a small amount of force required
For the past 18 months my front brake setup he been Shimano SLX BL-M7100-R lever, SLX BR-M7120 4 piston caliper with fined resin pads, SLX 203mm SM-RT70-L rotor & all I can say is 'perfecto', they are absolutely phenomenal brakes. Very powerful with amazing brake feel & control at any speed, I could easily lock up the front wheel at any speed & get bucked over the bars. Reliability is no issue either, I set them up a long time ago & not touched them since. A huge bonus too is that Shimano use mineral oil instead of DOT brake fluid. I couldn't recommend highly enough using this brake setup.
Shimano drivetrain and brake junkie here. XT levers with mt520 on my Stevo, XT levers with 8020 calipers on my Levo. Both 203 rotors. SLX levers and 7100 calipers on my Rascal. SLX and Deore levers and m615/m675 calipers on my ns eccentric chromo. 180 rotors on both. 12 speed Shimano drivetrains on the regular fs bikes. 11 speed Shimano on the hardtail. 10 speed linkglide on the e bike.

I love my Shimano brakes but can't say I've tried anything else LOL. My Optic came with MT-420 4 piston brakes with metalic pads, hated the levers so did a simple lever replacement with the M6100 levers and a bleed.

How are you liking them? Way better braking feel? I'm planning to do the same with my MT420 by swapping the levers to the 6100 levers or maybe the 8100 XT levers. They came on my Range VLT A2 so need all the braking power feel i can get.
@@illestFlavor I ride in Ontario and they are plenty powerful enough for me but I think the key point to the whole setup is the metalic pads and compatible rotors.

I have the older models too and those models had some “getting used to” because of the grabby feel. But I feel like these new models completely eliminated the grabby feel but without making them feel mushy like some other brands feel.

One of the things that I love about Shimano is that they are very easy to bleed and service. The Shimano Ice Tech rotors are pricey and so are the brake pads but you can get the less expensive Shimano rotors or other brands, same with the brake pads. I only use Shimano mineral oil but some people change that too. I really enjoy your channel and learning about your profession opinion and tips on bike wrenching. Thanks!

Thanks for adding to the post. I have started the video with that kind of detail in mind and I removed it quickly as the video would have been 15 minutes or so 🤓
ThnX! 7:22 - so, it looks like only a Deore M6100 rear caliper allows for a cut-to-the-size hose? I need a hose longer than the longest available with a banjo (ISMBH90SBML200 is only 2000mm long).
Deore is the only one that allows to use that tightening nut at both ends, caliper and lever so yeah if you can find a longer than 2000mm hose you can do it, pair a deore caliper with whatever lever you have.
I love my Shimano SLX 7100 2 pistons brakes. I just Upgraded my Rotor to a SRAM Centerline 180mm F/R . SLX 2 pistons Is superb I wish I could buy the 4piston but I'm happy with 2 piston on my Hardtail XC bike 💯 always Love to watch your video 💯💯
Thanks for the video. Just to share my own experience. When fitting my actual carbon frame/hardtail I went through a similar (but not so detailed) comparisson and opted for a set of 6100 levers and 6120 4 piston calipers, paired with RT76 rotors (180mm front and 160mm rear). Bike's weight is 12 kg and I'm about 80kg. Main use is recreational (I mean not race) XC and trail, including some downhill sections, not extremelly long but with very little space for braking and on mostly dry and loose surface terrain. To me this combination sounded as the best performance/price relationship for the intended use and I'm very happy with the resulting braking power and braking control (is this the so called modulation ??). So far I still using the stock resin pads for now.
I have the TRP Slate T4's that I installed on my Trance a few years ago. I like the brakes, but will admit, they do not have the quick stopping power, or bite, as my son's Shimano 520's he has on his Genius. I have to be careful riding his bike, since I'm used to the modulation on the TRP's, that I press too hard on his brakes and find myself continuing a bit over the handlebars while the bike was braking. Have to admit I like that stopping power and the smaller lever's. Have been considering a switch to the 520's possibly Deore that you setup for your bike. Thanks for the video, this is helpful on seeing the differences.
You're welcome! Your comment brings up a good point, brakes like those TRPs are considered to provide great modulation and that's obvious in the car parking test. However on the trail, real life, the so called on/ off Shimanos provide good braking power and enough modulation and the TRPs will feel weak and give you arm pump. Oh well...🙂
Great comparison video. Currently using XT 2 piston on my XC rig. And SRAM Code Silver Stealth (the ones with the hose closer to the bars) 4 piston on my trail rig.
@@LoveMTBBoth are amazing IMO. Excellent build quality and performance. The SRAM 4 pistons have greater stopping power and heavier. But since they’re on my trail bike, I’m not concerned about counting grams. Oh bleeding edge makes bleeding brakes easier than on Shimano mineral oil.
I ended up just changing my front brake on the Meta HT my most used bike to XT 4 piston but still running SLX 2 piston in rear. been working well I dont feel I need 4 piston in rear. Cheers
nice informative video. for a dream-built XC bike, with certainly aggressive decent riding, do you recommend XT brake 2 piston or 4 piston? Due avoid the XTR carbon blade break risk, can I use the XT lever with a 2-piston XTR caliper? Regardless of weight, do XTR calipers bring more value than Xt?
I would stay away from XTR TBH. Long story short, not worth the premium. 2 piston is more than enough. If you want more power w 2 piston look up my video on Formula Brakes 😉
I have 7120 SLX on all my bikes but add the XT Ice Tech rotors. I could not justify the cost of going with 8120 or 9120 for very minimal weight savings. I have been completely satisfied with the performance of the SLX braking, especially with the XT rotors, 203 front and 180 rear.
I have 7120 SLX too. I hate them. There is noticeable wandering bite point, especially in temperatures below 20 deg Celsius. In 10 degrees it's a serious problem. Brake is completely non-repetitive. It's not related to wrong bleeding. It's related to crappy seals material. I switched to Code RSC I my second bike and I love them.
Epic video! I'm running the SLX M7000 2-pot ones. Lovely so far in over 3 years, front was new while the rears were second hand. From my research back then for the Mx000 generation, XTR isn't worth it, XT had a bad batch in the beginning while SLX came later on the market and are spot on. Plus I got the new upgraded G05S pads for this new season. 203mm and 180mm matching SLX discs as well. Would love the M8120 ones day 😁
I've been contemplating going hydraulic on my everyday commuter. I've got mechanical Paul brakes. They are really nice and easy to adjust. My only issue is that my rear brake line froze internally because some water got in there and the temperature dropped in the 20's. I was able to still use my front brake however, so it wasn't a disaster. I put a new brake line on and used a better sealed endcap and also used some antifreeze in the line and so far haven't had it freeze again. I'm mainly curious if hydraulic brakes are susceptible to freezing?
Appreciate you covering the differences between I-Spec II and EV. I'm looking for a mount compatible with my Wolftooth dropper that will mate with my Deore XT brakes. Now I have a better idea what to look for!
I just bought yesterday the SLX 4 pistons. I only do wheelies and I use a lot the brake so I don’t want it to overheat. And I want strong brakes and reliable brakes. So I choose the SLX the XT doesn’t work for me, it’s always failing after wheelie for some time, the SLX are more reliable on that point. I don’t chose the deore or the 501 because I like the ice tech and the reach adjust 😁
I have the XT 8120 on one of my bikes and on the other one the Deores of 2015 (the grey ones) in 2 pot, and belive me I can barely tell a difference between them. Feels pretty much the same. Sure the 4 pot XTs have more power. But the feeling is 95% the same. I'm really impressed with the deore lineup even on drivetrain. Don't see the reason to spend more money on the more expensive series as long as you don't do races where weight matters.
I have Tektro 4 piston on my bike and they work well even with the stock pads. I have thought about changing to Deore 6120's but just can't justify spending the money when the Tektro's do so well. If anything breaks then I'll switch over.
Great explanation! I’m thinking about performing multiple upgrades to my bike, including brakes. I want to get rid of my Tektro brakes - good brakes, poor parts availability. I think I’ll go with SLX.
Nice video buddy. I’ve just got a Vitus sommet which comes with sram brakes I’m wanting to swap them out I really don’t like them. Can I use scram Rotas on shinmano brake sets?
With what rotors? Size? Make? What pads? Warmed up or not? How strong is your finger? 😊 4 piston are about 20% more powerful than 2-piston@@gammelgemse
I recently built up my hardtail, using a set of MT520 calipers, i don't like the big non servo wave levers so I bought a set of SLX levers, mated with 302mm rotors front and rear(mind you it's an "enduro" hardtail) and you've got some insanely good stopping power on a budget! I've got full XT 4pot on my Stumpjumper and I almost like the cheaper set better!
How do you like the Hayes? They are some of the innovators in the hydraulic brakes! Together with Shimano. And I did have a set of M6000 that I used on a couple of bikes, bombproof!
Informative video. My bike came stock with Shimano MT201. I recently just upgraded my groupset to XT. I've been reading about some issues with the XT 2 pistons, so I am hesitant to go this route. Leaning toward the deore 6100 which should be a decent enough setup and an upgrade from the mt201
I am using all of them from Deore to XT to 4-piston. They are all good, get the one that makes more sense for you price and features, performance will be very similar.
I have mt420 quads as my first hydraulic brakes and now i am planning to replace the levers with very tight budget. What lever you can suggest? I am eyeing to slx levers. Tnx.
I've been watching your fantastic videos for more than a decade (fellow MTBRer) and I don't think you've ever really talked about the wandering bite point that everyone complains about regardless of whether or not they actually experience it. What's your take on this problem with the newer generation of servo-wave levers?
Thanks for sticking with me for this long😊 I had one of the first batches of XT brakes with e the issue and they replaced them under warranty no questions asked. No more issues after that. A good bleed helps!
In my opinion free stroke is the biggest problem with hydraulic disk brakes. I trick it down by overfilling, so I have around 12mm at the end of my XT 8000 levers with 4 piston calipers, but 7 to 5 mm, as it was possible with cantilevers, would be much better. In this regard I like 2 pistons more than their big brothers. A lot of riders work around free stroke problems, adjusting their levers super close to the grips or having one finger on the lever all the time, but that's not for me. Are there any differences coming with the latest shimano generation?
Not meaningful no, but you can use the free stroke/ bite point on the XT/ XTRs for that. I would go 2-piston though if you want minimum pad clearance, that's pretty much what you're asking for.
I'm currently using a Deore M6100 2 piston brake, do you think it worth upgrading my front rotor from 180mm to 203mm? Will this upgrade brings more braking power?
Now I'm pairing a MT200 dual piston calipers with M7100 levers. Correct me if I am wrong, is the caliper of MT200 is just the same as the dual pistons of M-series brakes?
right now I have a canyon strive that came with the xtr brakes, but before that I had a different bike with slx brakes. I can barely feel any difference. altho I maybe think the xtr is slightly more stiff
Hey man, quick question... My Eeb (e-mtb) came w/ TRP Slate 4 Piston brakes. They're seriously underpowered for the bike (& me @245lb's). I'm looking at getting XT M8120 & thought you might know answer to this one... do the XT M8120's suffer from the wandering bite point issue? Second question, you mention the straight Deore M6120... do you think they'd be up to the task w/ a 50lb rig & 245lb rider? Many thanks 👍
Deores will be just fine, you can ue the finned pads from Zee / Saint with them if you want. Interesting that you're the seccond biker in the chat to ask about the TRP Slate great modulation/ underpowered performance.
PERFECT explanation, love all the videos, but I want to add information: there is another difference on XT and XTR Lever blades: XTR is forged and XT is bent sheet metal
@@LoveMTB I am in the process of changing my Guide RE, I had arm pump issues all summer long and I just realized that with my Saints, I never had that issue. So I am thinking either XT 8120 or Saints... 9120, I do not see the value, they are so expensive
@LoveMTB They still work😁👍👍. I also was using XTR/XT replacement pads for years👍👍. Now im using ok Jegwire pads. I also used Jegwire Kevlar brake casing for years🤘🤘
No mention of the ceramic pistons? Do all MTB groups use ceramic? My XT M8120 ceramic pistons just cracked and there is no good replacement!! I hear these are a problem with Shimano brakes. Hoping they change materials soon....
In every day use nobody really cares if the pistons are ceramic or not. I have videos describing in detail each brake type this is more like a summary of that info. Links in the description. As for breaking/ cracking, in 10 years of using them, various variants I only had issues with one. Cracked, but entirely my fault…
@@LoveMTB Thanks - but since this happened to me, and with only moderate use, I now find hundreds of others online complaining about Shimano pistons. In fact, an entire 3rd party Chinese mfg. industry replacing Shimano pistons exists! Unfortunately many of these Chinese replacement resin pistons also have some issues. This is not a small problem with modern Shimano calipers.. I think maybe you got lucky. This is why I was asking if all groups (Deore, SLX, XT, XTR) all use ceramic pistons.... I want to replace my XT 8120 calipers but keep my levers.
I've seen many reports about the SLX M7100 lever snapping easily. They made the lever blade thinner at the thinnest point where it's meant to bend, if you smash it, instead it snaps.
@@LoveMTB I've never done this, but a guy bought a bike second hand and the plastic guide was snapped. Imo material choice eis absurd so is no spare parts.
@@LoveMTB Thanks for the heads up. I had 2 piston XT's on my old bike it seemed like bite point was closer the stop of stroke on the lever. That's where I like it.
hey guys, what do u think about the "old" zee brakes Vs the new slx/xt brakes? I mean Shimano didn't updated the zee for a pretty long while. I dont know if the new generation of slx/xt are already better or at least on the same level as the zee?
The non-servo wave XTR levers feel no different in terms of lever feel IMO. The pads sit closer to the rotor making set up a bit more tricky but the feel under braking has better modulation.
Depending on the application they will feel weaker also. Some use those levers with 4-piston calipers for the ultimate "modulation". But I feel that modulation is an overused term to define brake performance.
@@LoveMTB totally agree. I have my XC bike with M9100 levers (no Servowave) and M9120 callipers,… and my trail bike with M8120 brake/levers …. The brake feel of the XTs is much better in my opinion. Haven’t tried the M9120 levers though.
What a phenomonal video, thank you! As someone brand new to bikes, I have been so confused about so many things, and this cleared up a lot. My only existing doubt I have, in case anyone is kind enough to help me....I currently have SRAM X9 shifters, attached to Avid Elixir levers (2011 Stumpjumper std kit). Once i put the Shimano levers, I will have nowhere to attach the shifters, I'm sure its obvious to anyone with experience, but what are my options here? Do I buy new clamps for the shifters, or is there a way to mount them to the Shimano's in a similar way I have them now? Thanks!
Side note: at XTR level Shimano uses different bajo and screw bc of the magnesium material. SLX lever's bolt is act like a fully turned in XT and XTR "free stroke adjuster".
I recently built up a new hardtail with 1x12 XT drivetrain and SLX M7100 brakes on RT70 180/160 rotors. the rear brake works perfectly smooth, however the front rotor has a distinctive bite spot, which causes it to pulsate under braking. i've cleaned the rotor and given it additional time to wear-in, but the pulsating persists : / Is there anything else i can try, or is replacing the front rotor the only solution?
RT70 rotors, center lock. not bent, they run true, front one just seems to have an inconsistent braking surface. i built everything with brand new parts... it's odd?
I fitted a BR-M6120 to my hardtail a few days ago and apart from the look there is no difference in performance to my BR-M8120. All I did was cut a M4 thread so I could use a pad retainer bolt and fitted some D02 sintered pads, all in 5 minutes. For me there is no need to spend the extra money over the Deore BR-M6120 brakes.
I have SLX on my fat bike and that's the only bike with Shimano I have. Brake power is god, no complains. But what I like the most is the levers. I just like how small and curved they are. I have a feeling I have less finger travel, or let's say they are natural finger move when squishing compared to Stram when my fingers go in some awkward direction. Is not that bad, still not perfect. TRP brakes are close to Shimano. Still, the levers are more towards to Sram levers than Shimano.
Hi LoveMTB, I know you probably don't have the time for this. But can you measure the width of the widest part of the Deore XT or SLX dual piston calipers? The part where there is a head of a screw protruding the left side of the caliper (when facing towards the front of the bike). The reason I ask is that my Deore caliper, because of its new design, could not clear the seat stay of my frame if I try to install an 180mm rotor adapter so I'm stuck with the 160mm rotor. I was wondering if the Deore XT or SLX will solve this issue for me.
Just want to mention that a friend has the xtr and he fell two times on the levers and he had do drill the existing screw hole as the screw broke, and also the body lever bended. As a design i feel that the sram levers are more robust and even the ultimate with the carbon levers are more durable then Shimano. I would not recomend the xtr as they are to high as a price. I feel like they are fragile.
I don't know about durability as we prefer to ride the bike upright ☺ but I agree with you on the XTRs. But they are race components after all they're supposed to be the lightest not the most durable.
Yes, the 7100/8100 levers bend nuch easier than the 7000/8000 series levers. This is because where there is a kind of fold in the lever, the new style ones are pressed a bit tighter than the older ones. Hard to explain unless comparing the two. Also, I cannot tell any difference in stiffness between the old & new style. I actually prefer the old style because of the stronger lever & they take up less space on the bars.
@@LoveMTB Yeah. Well, I always use the bar attachment option. That way all my kit is backward, forward & sideways (other brands) compatible. Never understood why people claim that having a black bar clamp fitting on the dropper & shifter levers makes the bars cluttered - it does not. In fact, with the new style levers my dropper & shifter bar clamps fit between the two contact points of the brake lever & so take up zero extra space on the bars.
@@45graham45 even that the new clamping style makes them a bit more powerfull, you can't loosen them to spin around the bar in case of a crash. Ore they are to tight or to lose on the handlebar. Maybe just one point of clamping on the bar but a bit bigger is a better design then two point clamping.
Everyone keeps saying the shimano xt m8100 and 8120,levers are the same ,they are not! The 8120 lever is taller and flatter than the M8100's .if you buy an aftermarket xt lever you get the 8120 but oem they are completely different levers ....
@@LoveMTB taken directly from shimano The Shimano Deore XT BL-M8100 and BR-M8120 are both disc brakes with different lever designs:   M8100 This brake has a two-piston design and a stiffer lever that provides support for aggressive riding. It also has Servo Wave technology, which causes the pad to move quickly to the disk surface for an aggressive initial bite. One reviewer says the M8100 has raw stopping power and that the brakes lock up easily.    M8120 This brake has a four-piston caliper and a more progressive modulation than the M8100. It's designed for tough enduro trails and has finned metal pads and hose. The lever is taller and flatter than the M8100's, and some say it provides reliable stopping power in all
I agree with you I honestly think they used to be ....but I've just bought a complete brake set xt 8120 4 pot for the front and 8100 2 pot for the tear and the levers are different....I didn't,y notice at first but its thinner on the M8100 and the design is subtlety different.....bought from a shop who sells shimano in the UK and 3 days after querying it they got told from the UK shimano distributor this is a running change moving forward . Made in a new factory in Taiwan .....apparently
@@knott4me561 I hear you, but having them in my hand, side by side, mixing them and using them I can tell you the lever is the same (BL). Only difference is that on the OEM version you’ll see J-kit written on the back
i have m6100 and m7120. honestly i dont feel any difference. haha. both superb brakes, great stopping power and easy maintenance! but i guess m6100 wins coz its half the price!
I just got a canyon torque on e freeride e bike and it comes with the new SLX brakes. I am really surprised how powerful they are and how good they feel.

I have the TRP Slate T4's that I installed on my Trance a few years ago. I like the brakes, but will admit, they do not have the quick stopping power, or bite, as my son's Shimano 520's he has on his Genius. I have to be careful riding his bike, since I'm used to the modulation on the TRP's, that I press too hard on his brakes and find myself continuing a bit over the handlebars while the bike was braking. Have to admit I like that stopping power and the smaller lever's. Have been considering a switch to the 520's possibly Deore that you setup for your bike. Thanks for the video, this is helpful on seeing the differences.
You're welcome! Your comment brings up a good point, brakes like those TRPs are considered to provide great modulation and that's obvious in the car parking test. However on the trail, real life, the so called on/ off Shimanos provide good braking power and enough modulation and the TRPs will feel weak and give you arm pump. Oh well...🙂
Great comparison video.
Currently using XT 2 piston on my XC rig.
And SRAM Code Silver Stealth (the ones with the hose closer to the bars) 4 piston on my trail rig.
Thanks for sharing! How would you compare the performance of the two?
@@LoveMTBBoth are amazing IMO. Excellent build quality and performance. The SRAM 4 pistons have greater stopping power and heavier. But since they’re on my trail bike, I’m not concerned about counting grams. Oh bleeding edge makes bleeding brakes easier than on Shimano mineral oil.
Good to know I won’t avoid them when I come across the new high end sram brakes
@@LoveMTBThe new design allows for the hose to sit closer to the handlebar. It looks cleaner for sure.
Yeah wouldn't be the deciding factor for me though@@GokkunGuru
XT everything boiii
The best 😎 🔝 (I consider XTR for racing only, absolutely overkill for amateurs)
I ended up just changing my front brake on the Meta HT my most used bike to XT 4 piston but still running SLX 2 piston in rear. been working well I dont feel I need 4 piston in rear. Cheers
With you, I have 4-piston front only on my bikes😉
nice informative video. for a dream-built XC bike, with certainly aggressive decent riding, do you recommend XT brake 2 piston or 4 piston? Due avoid the XTR carbon blade break risk, can I use the XT lever with a 2-piston XTR caliper? Regardless of weight, do XTR calipers bring more value than Xt?
I would stay away from XTR TBH. Long story short, not worth the premium. 2 piston is more than enough. If you want more power w 2 piston look up my video on Formula Brakes 😉
@@LoveMTB tnx for quick response. for a versatile gear, without budget concern, what is your recommendation?
@@sepantsystem2237 Still Formula 2 piston unless you want to stick w/ Shimano in which case it's XT
@@LoveMTB I mean the derivation system. Agree 1S with the 12-speed rear? Or 11 s with 2X front derailleur?
@@sepantsystem2237 there no more room for 2x in XC majority of frames won’t take a front derailleur anymore anyway. No need for it these days
I have deore mt6100 on my honzo and a got then cheap off chain reaction they gave me the black shimano logo ones they really good
I have 7120 SLX on all my bikes but add the XT Ice Tech rotors. I could not justify the cost of going with 8120 or 9120 for very minimal weight savings. I have been completely satisfied with the performance of the SLX braking, especially with the XT rotors, 203 front and 180 rear.
Nice capable setup!
I have 7120 SLX too. I hate them. There is noticeable wandering bite point, especially in temperatures below 20 deg Celsius. In 10 degrees it's a serious problem. Brake is completely non-repetitive.
It's not related to wrong bleeding. It's related to crappy seals material. I switched to Code RSC I my second bike and I love them.
Great info broken down professionally Thank you
You’re welcome
Congratulation, great video, I'm using shimano xt m8100 and I love it.
Thanks for sharing! We have more XT brakes used than anything else.
Hey great video. Any compatibility issues with 7000 2 pot caliper and 6100 lever?
Thanks!
Yes, they will work well together, also have this video - ua-cam.com/video/WK5Ve5Vgc8I/v-deo.html
Epic video! I'm running the SLX M7000 2-pot ones. Lovely so far in over 3 years, front was new while the rears were second hand.
From my research back then for the Mx000 generation, XTR isn't worth it, XT had a bad batch in the beginning while SLX came later on the market and are spot on. Plus I got the new upgraded G05S pads for this new season. 203mm and 180mm matching SLX discs as well.
Would love the M8120 ones day 😁
Yeah I had a set of the original XTs, they replaced them without asking much 😁
Great comparison vid!!! My fav so far is the xt 8120 and pretty straight forward to bleed also.Cheers!!!
So if I buy a m6100 lever will it work with 4 pot brakes?

Thinking about the slx over the deore is it worth it?
For me it i not...
@@LoveMTB yeah I didn't see much after looking into it. But I went in yesterday and got a smoking deal on the SLX so I couldn't resist
@@soulsikk2011 I hear you 😊
new subs here from the philippines ❤
I've been contemplating going hydraulic on my everyday commuter. I've got mechanical Paul brakes. They are really nice and easy to adjust. My only issue is that my rear brake line froze internally because some water got in there and the temperature dropped in the 20's. I was able to still use my front brake however, so it wasn't a disaster. I put a new brake line on and used a better sealed endcap and also used some antifreeze in the line and so far haven't had it freeze again.
I'm mainly curious if hydraulic brakes are susceptible to freezing?
Probably not as bad as the mechanical, I've never heard of them freezing.
Consider the Shimano MT200 brakes. Dirt cheap and excellent.
@@ericjensen4434 depending on the application 😎
Appreciate you covering the differences between I-Spec II and EV. I'm looking for a mount compatible with my Wolftooth dropper that will mate with my Deore XT brakes. Now I have a better idea what to look for!
Upgraded to 7120's for me. I quite like the blue...ish colour. 4 pistons seem trickier to setup consistently compared to my previous 2 piston Tektros.
Yup harder to keep them from rubbing
May i ask is your XT lever have a Scratch
@@fishingpet1992 that set of XT levers is well used, not scratch but the paint is worn out on the lever blades
@@LoveMTB because I saw some Looks Scratch on other of your video about XT lever
I just bought yesterday the SLX 4 pistons. I only do wheelies and I use a lot the brake so I don’t want it to overheat. And I want strong brakes and reliable brakes. So I choose the SLX the XT doesn’t work for me, it’s always failing after wheelie for some time, the SLX are more reliable on that point. I don’t chose the deore or the 501 because I like the ice tech and the reach adjust 😁
I have the XT 8120 on one of my bikes and on the other one the Deores of 2015 (the grey ones) in 2 pot, and belive me I can barely tell a difference between them. Feels pretty much the same. Sure the 4 pot XTs have more power. But the feeling is 95% the same. I'm really impressed with the deore lineup even on drivetrain. Don't see the reason to spend more money on the more expensive series as long as you don't do races where weight matters.
With you on that...
I have Tektro 4 piston on my bike and they work well even with the stock pads. I have thought about changing to Deore 6120's but just can't justify spending the money when the Tektro's do so well. If anything breaks then I'll switch over.
We've only used Tektro on kids/ beater bikes, 2-piston and they never ever gave us trouble. BTW you know THEY are behind TRP...
@@LoveMTB Did not know that.
Yup😊@@donnovicki9771
Great explanation! I’m thinking about performing multiple upgrades to my bike, including brakes. I want to get rid of my Tektro brakes - good brakes, poor parts availability. I think I’ll go with SLX.
Not a bad choice!
Shimano Brakes and SRAM gears is my preferred combo.
With you on that😊
Nice video buddy. I’ve just got a Vitus sommet which comes with sram brakes I’m wanting to swap them out I really don’t like them. Can I use scram Rotas on shinmano brake sets?
Yes you can but if they are the Centerline / most probably/ they’re not that good
Yes they’re centreline. Do you reckon I should swap these too? Cheers for the advise
@@syms85 I would, and the cheap SLX rotors from Shimano are good
How does the braking power compare? 🤔
Which ones are you loooing at?
@@LoveMTBnone specifically, just curious which are the most powerful ones.
With what rotors? Size? Make? What pads? Warmed up or not? How strong is your finger? 😊 4 piston are about 20% more powerful than 2-piston@@gammelgemse
I recently built up my hardtail, using a set of MT520 calipers, i don't like the big non servo wave levers so I bought a set of SLX levers, mated with 302mm rotors front and rear(mind you it's an "enduro" hardtail) and you've got some insanely good stopping power on a budget! I've got full XT 4pot on my Stumpjumper and I almost like the cheaper set better!
Haha exactly, blind test hard to tell which one is which from Deore all the way up
Great vid 👍 Quick question will the current shimano 12 speed brake lever range (mt6120-mt9120) work with the shimano MT420 4 piston calipers?
Yes but be careful with the line connection, MT420 has a straight in hose just like the Deore.
@@LoveMTB Thank you 🙏
Very nice review!
Can I still use my clamp style 12-sp XT shifter with 8100 levers?
For sure! 👍
Pls make a video for the banjo fitting (short/long) compatibility for shimano 2 piston and 4 piston brakes..
Great suggestion but there isn’t much to it some calipers / generation of calipers have a longer bolt than others that’s it🙂
Love Shimano brakes, thanks
We only use Formula and Shimano so I guess we can say the same😊
And sorry, I do SLX brakes of the choices
We used SLX a lot in th epast, not the current generation as I don't like the bluish color☺@@Jacob99174
I put half a decade of use on M6000 brakes with few problems; but I showed Shimano my opinion on i-spec EV by substituting Hayes T2 brakes.
How do you like the Hayes? They are some of the innovators in the hydraulic brakes! Together with Shimano. And I did have a set of M6000 that I used on a couple of bikes, bombproof!
@@LoveMTB I like them a lot, but I'm also easy on brakes.
Thank you, this was usefull - as allways. Imo Shimano has the best brakes, no matte 2 or 4 pistons both are very powerfull, cheers :)
Agree, it's almost all we use 😁
Informative video. My bike came stock with Shimano MT201.
I recently just upgraded my groupset to XT. I've been reading about some issues with the XT 2 pistons, so I am hesitant to go this route.
Leaning toward the deore 6100 which should be a decent enough setup and an upgrade from the mt201
I am using all of them from Deore to XT to 4-piston. They are all good, get the one that makes more sense for you price and features, performance will be very similar.
@LoveMTB, thanks for the response. Ordered my Deore 6100s online, yesterday. The reports of a wondering bite point on the 8100s threw me off.
@@ashokhargovan9603 you’ll be happy with those
I have mt420 quads as my first hydraulic brakes and now i am planning to replace the levers with very tight budget. What lever you can suggest? I am eyeing to slx levers. Tnx.

@@LoveMTB thank you
Can shimano mtb brakes be used with shimano road levers??
Nope different pull ratio
I've been watching your fantastic videos for more than a decade (fellow MTBRer) and I don't think you've ever really talked about the wandering bite point that everyone complains about regardless of whether or not they actually experience it. What's your take on this problem with the newer generation of servo-wave levers?
Thanks for sticking with me for this long😊 I had one of the first batches of XT brakes with e the issue and they replaced them under warranty no questions asked. No more issues after that. A good bleed helps!
Do you know why the XTR uses a flat head for the pad retention vs. the allen on the lower versions? I've always wondered, it seems to be a down grade.
It is a flat head indeed, don't know why. Maybe so you don't overtighten it given that the caliper is made out of magnesium?
It's more likely you always easily can get a flat head driver rather than allen 😎🔝👊🏻 for convenience I guess, the R in XTR stands for race after all
Thanks for this great video and the comparision. I use the BR-MT520/500 on my fully and it´s the best brake i ever head
i went for the mt520 calipers.
In my opinion free stroke is the biggest problem with hydraulic disk brakes.
I trick it down by overfilling, so I have around 12mm at the end of my XT 8000 levers with 4 piston calipers, but 7 to 5 mm, as it was possible with cantilevers, would be much better.
In this regard I like 2 pistons more than their big brothers.
A lot of riders work around free stroke problems, adjusting their levers super close to the grips or having one finger on the lever all the time, but that's not for me.
Are there any differences coming with the latest shimano generation?
Not meaningful no, but you can use the free stroke/ bite point on the XT/ XTRs for that. I would go 2-piston though if you want minimum pad clearance, that's pretty much what you're asking for.
I'm currently using a Deore M6100 2 piston brake, do you think it worth upgrading my front rotor from 180mm to 203mm? Will this upgrade brings more braking power?
@@GeoffGao 15% or so more if you need it
@@LoveMTB Thank you ! Like your channel which really helps me a lot!😁
Now I'm pairing a MT200 dual piston calipers with M7100 levers. Correct me if I am wrong, is the caliper of MT200 is just the same as the dual pistons of M-series brakes?
@@amveeeee similar to the Deore yes
Nice vid , I use SLX 4 pot and did the mod 😇 metal pads 203 front 180 rear .
Right on!😇
right now I have a canyon strive that came with the xtr brakes, but before that I had a different bike with slx brakes. I can barely feel any difference. altho I maybe think the xtr is slightly more stiff
Could be but for what price delta? 😏
Hey man, quick question... My Eeb (e-mtb) came w/ TRP Slate 4 Piston brakes.
They're seriously underpowered for the bike (& me @245lb's).
I'm looking at getting XT M8120 & thought you might know answer to this one... do the XT M8120's suffer from the wandering bite point issue?
Second question, you mention the straight Deore M6120... do you think they'd be up to the task w/ a 50lb rig & 245lb rider?
Many thanks 👍
Deores will be just fine, you can ue the finned pads from Zee / Saint with them if you want. Interesting that you're the seccond biker in the chat to ask about the TRP Slate great modulation/ underpowered performance.
@@LoveMTB Slates would be great on a trail bike.... they're just underpowered for my AM E-MTB 🙁
Great brakes for the right application for sure@@kingrat738
PERFECT explanation, love all the videos, but I want to add information: there is another difference on XT and XTR Lever blades: XTR is forged and XT is bent sheet metal
Nice catch! And SLX and XT levers seem to be different also, pretty sure cheaper manufacturng on SLX
What is one way bleeding?
Running Deore 4 piston and upgraded to metal pads, huuuge performance upgrade and cheap with just pads
Well sure longer lasting, less bite, noisier. So don’t know if better or upgrade?😊
@@LoveMTB Bite Way better, and won’t overheat. You must have had some bad pads
What abt shimano saints???

@@LoveMTB I am in the process of changing my Guide RE, I had arm pump issues all summer long and I just realized that with my Saints, I never had that issue. So I am thinking either XT 8120 or Saints... 9120, I do not see the value, they are so expensive

No mention of the ceramic pistons? Do all MTB groups use ceramic? My XT M8120 ceramic pistons just cracked and there is no good replacement!! I hear these are a problem with Shimano brakes. Hoping they change materials soon....
In every day use nobody really cares if the pistons are ceramic or not. I have videos describing in detail each brake type this is more like a summary of that info. Links in the description. As for breaking/ cracking, in 10 years of using them, various variants I only had issues with one. Cracked, but entirely my fault…
@@LoveMTB Thanks - but since this happened to me, and with only moderate use, I now find hundreds of others online complaining about Shimano pistons. In fact, an entire 3rd party Chinese mfg. industry replacing Shimano pistons exists! Unfortunately many of these Chinese replacement resin pistons also have some issues. This is not a small problem with modern Shimano calipers.. I think maybe you got lucky. This is why I was asking if all groups (Deore, SLX, XT, XTR) all use ceramic pistons.... I want to replace my XT 8120 calipers but keep my levers.
I've seen many reports about the SLX M7100 lever snapping easily. They made the lever blade thinner at the thinnest point where it's meant to bend, if you smash it, instead it snaps.
Don’t smash it!?😊
@@LoveMTB I've never done this, but a guy bought a bike second hand and the plastic guide was snapped. Imo material choice eis absurd so is no spare parts.

@@LoveMTB Thanks for the heads up. I had 2 piston XT's on my old bike it seemed like bite point was closer the stop of stroke on the lever. That's where I like it.
I have the XTR M9100 2 piston calipers and the XC race version levers 🗿🔝 best brakes I've ever had
I also have the XT M8100 on my older 26er
No you like the no Serviwave lever better? Interesting setup for sure
hey guys, what do u think about the "old" zee brakes Vs the new slx/xt brakes? I mean Shimano didn't updated the zee for a pretty long while. I dont know if the new generation of slx/xt are already better or at least on the same level as the zee?
They are still great brakes but lever mounting options is outdated
The non-servo wave XTR levers feel no different in terms of lever feel IMO. The pads sit closer to the rotor making set up a bit more tricky but the feel under braking has better modulation.
Depending on the application they will feel weaker also. Some use those levers with 4-piston calipers for the ultimate "modulation". But I feel that modulation is an overused term to define brake performance.
@@LoveMTB totally agree. I have my XC bike with M9100 levers (no Servowave) and M9120 callipers,… and my trail bike with M8120 brake/levers …. The brake feel of the XTs is much better in my opinion. Haven’t tried the M9120 levers though.
What a phenomonal video, thank you! As someone brand new to bikes, I have been so confused about so many things, and this cleared up a lot. My only existing doubt I have, in case anyone is kind enough to help me....I currently have SRAM X9 shifters, attached to Avid Elixir levers (2011 Stumpjumper std kit). Once i put the Shimano levers, I will have nowhere to attach the shifters, I'm sure its obvious to anyone with experience, but what are my options here? Do I buy new clamps for the shifters, or is there a way to mount them to the Shimano's in a similar way I have them now?
Thanks!
Thanks!
And depending on how they were attached to the brakes you might be able to find the usual SRAM bar clamps.
Side note: at XTR level Shimano uses different bajo and screw bc of the magnesium material.
SLX lever's bolt is act like a fully turned in XT and XTR "free stroke adjuster".
Thanks for adding the details!

I recently built up a new hardtail with 1x12 XT drivetrain and SLX M7100 brakes on RT70 180/160 rotors. the rear brake works perfectly smooth, however the front rotor has a distinctive bite spot, which causes it to pulsate under braking. i've cleaned the rotor and given it additional time to wear-in, but the pulsating persists : /
Is there anything else i can try, or is replacing the front rotor the only solution?
RT76 rotors? bent at all?
RT70 rotors, center lock. not bent, they run true, front one just seems to have an inconsistent braking surface. i built everything with brand new parts... it's odd?
Very nice brakes, even the Deore. I run Magura, but wouldn't recommend ever spending money to swap from a Shimano brake.
Agree, hard to justify
I fitted a BR-M6120 to my hardtail a few days ago and apart from the look there is no difference in performance to my BR-M8120. All I did was cut a M4 thread so I could use a pad retainer bolt and fitted some D02 sintered pads, all in 5 minutes. For me there is no need to spend the extra money over the Deore BR-M6120 brakes.
Agree 💯
Trying to find genuine pads just now near impossible!
They’re available here in Canada where are you?
I have SLX on my fat bike and that's the only bike with Shimano I have. Brake power is god, no complains. But what I like the most is the levers. I just like how small and curved they are. I have a feeling I have less finger travel, or let's say they are natural finger move when squishing compared to Stram when my fingers go in some awkward direction. Is not that bad, still not perfect. TRP brakes are close to Shimano. Still, the levers are more towards to Sram levers than Shimano.
I use m8000 with m7120 in front and m7100 on rear along with rt70 203/180
Nice 👍
I love my 8120.
Deore XT 😎🔝
I love my HOPE TECH 4 😈
People rave about them, I’m still to give them a try
Hi LoveMTB, I know you probably don't have the time for this. But can you measure the width of the widest part of the Deore XT or SLX dual piston calipers? The part where there is a head of a screw protruding the left side of the caliper (when facing towards the front of the bike). The reason I ask is that my Deore caliper, because of its new design, could not clear the seat stay of my frame if I try to install an 180mm rotor adapter so I'm stuck with the 160mm rotor. I was wondering if the Deore XT or SLX will solve this issue for me.
I laughed pretty hard when you called the free stroke adjustment the do nothing screw because as far as I can tell, that’s what it does.
Oh yeah I’ve always called it that😊
Thank you for information. 👍
Anytime
Nothing wrong with Shimano brakes. I use them on my daily bike to the office. But when it comes to my MTB, nothing beats Trickstuff Maxima.
Still to try those
Just want to mention that a friend has the xtr and he fell two times on the levers and he had do drill the existing screw hole as the screw broke, and also the body lever bended. As a design i feel that the sram levers are more robust and even the ultimate with the carbon levers are more durable then Shimano. I would not recomend the xtr as they are to high as a price. I feel like they are fragile.
I don't know about durability as we prefer to ride the bike upright ☺ but I agree with you on the XTRs. But they are race components after all they're supposed to be the lightest not the most durable.
Yes, the 7100/8100 levers bend nuch easier than the 7000/8000 series levers. This is because where there is a kind of fold in the lever, the new style ones are pressed a bit tighter than the older ones. Hard to explain unless comparing the two. Also, I cannot tell any difference in stiffness between the old & new style. I actually prefer the old style because of the stronger lever & they take up less space on the bars.
@@45graham45 💯 prefer the old style for more space on the bar but don't like the old I-SPEC II attachment style for the accessories.
@@LoveMTB Yeah. Well, I always use the bar attachment option. That way all my kit is backward, forward & sideways (other brands) compatible. Never understood why people claim that having a black bar clamp fitting on the dropper & shifter levers makes the bars cluttered - it does not. In fact, with the new style levers my dropper & shifter bar clamps fit between the two contact points of the brake lever & so take up zero extra space on the bars.
@@45graham45 even that the new clamping style makes them a bit more powerfull, you can't loosen them to spin around the bar in case of a crash. Ore they are to tight or to lose on the handlebar. Maybe just one point of clamping on the bar but a bit bigger is a better design then two point clamping.
Everyone keeps saying the shimano xt m8100 and 8120,levers are the same ,they are not! The 8120 lever is taller and flatter than the M8100's .if you buy an aftermarket xt lever you get the 8120 but oem they are completely different levers ....

@@LoveMTB the are not even shimano now list them as being different....
@@LoveMTB taken directly from shimano The Shimano Deore XT BL-M8100 and BR-M8120 are both disc brakes with different lever designs:


M8100
This brake has a two-piston design and a stiffer lever that provides support for aggressive riding. It also has Servo Wave technology, which causes the pad to move quickly to the disk surface for an aggressive initial bite. One reviewer says the M8100 has raw stopping power and that the brakes lock up easily.



M8120
This brake has a four-piston caliper and a more progressive modulation than the M8100. It's designed for tough enduro trails and has finned metal pads and hose. The lever is taller and flatter than the M8100's, and some say it provides reliable stopping power in all
I agree with you I honestly think they used to be ....but I've just bought a complete brake set xt 8120 4 pot for the front and 8100 2 pot for the tear and the levers are different....I didn't,y notice at first but its thinner on the M8100 and the design is subtlety different.....bought from a shop who sells shimano in the UK and 3 days after querying it they got told from the UK shimano distributor this is a running change moving forward .
Made in a new factory in Taiwan .....apparently
@@knott4me561 I hear you, but having them in my hand, side by side, mixing them and using them I can tell you the lever is the same (BL). Only difference is that on the OEM version you’ll see J-kit written on the back
