Huh, I've never done that. I started on a cg125 and that had a fixed rotor (04 model). I got a bandit 650 around a year and some change ago and I've never even thought to check the bobbins. No wonder my brakes feel so pulsey and horrid. It's not ABS, I've tested that with the rear brake by stomping it. First bike with ABS, dual free floating rotors (holy stoppying power), more than 1 cylinder... Lotta fun lmao. Cheers for this tip, hopefully solves my gammy brakes!
Old video but perfect. Noticed the bobbins on my z1000 were locked tight. It’s in for warranty and they are replacing them all but it’s good to know this could be the fix. Keep it clean.
Cheers Mr B I've got grabbing at the front so gonna try that today to see if it sorts it out ,I was always under the impression that the bobbing should not move and got new disc when they were lose,looking at your video I've been giving money away for no reason.
This procedure isn't recommended by any company. I used to think it was a good idea but after a little research I found out why not to do this. Anyone attempting this should look for arguments against this procedure.
Of,.. They want you to buy a new set of disc's.. There are freeplay in new sets, in my mechanical orientation, a pair of turning bobbins, will take less heat from the outer ring to the inner,. Also, takes out resonance and vibration in the front.. Have felt this on a Brembo system, where the bobbins was set free.. Guess there are other systems which don't allow you to turn them(oval).. To all who are calling Bs,.. I belive this guy.. ua-cam.com/video/J6ZeN2mYFao/v-deo.html
As @michael hefford mentioned Mat on the youtube channel the workshop explains in detail why making your bobbins move is isn't needed, doesn't do anything (same as people still putting copper grease on the rear of brake pads 😭) . ECB have brought out oval bobbings, these cannot move yet are on floating discs which proves they do not need to move.
floating buttons, rotors are for thermal expansion and greater performance, checking the tension and not able to turn buttons on a cold day? try again on a hotter day, its all about expansion
Holman, no don't do it this muppet will get people killed, they should not be loose, they hold the outer brake disc forgod sake, this muppet needs his bike licence revoked & the busa sold fucking prick.
Don't forget to grease the discs themselves so they glide through the caliper, reducing resistance. Now go out and ride really really fast and enjoy that reduced friction.
Cool video mate 😎👍 hayabossa a is for a boss 🤪 hey nice shoes you got ! What brand are they ?! I got new titanium bobbins in gold and silver from AliExpress for my 2019 CB1000-R 👍
Thanks for the how to... will do this when I do my next brake pad change on my Triumph Speed Triple. Good use of the two cameras and the 'blue print' idea was interesting.
Rhin0Neil Thanks Buddy, you want them to stay dry, any lube will attract and hold onto the brake dust/Grit n shit, so they will clog sooner. Just keep em dry and rinse them well in the winter with cold water to keep the salt away. RSMF-*RI* Mr B
Mr & Mrs B's Brain Dump thanks.. Was not too sure as some bloke in USA calls them buttons, and puts oil on his.. ua-cam.com/video/nqcHw_t3QlU/v-deo.htmlm45s
Rhin0Neil Wow that's a long bolt! As for oil, what do you think? Adding oil to you brake disc? lol - No, no oil or grease just dry. The idea of adding lubricant to brake discs is a whole world of wrong, it will fling out across the disc! No thanks!
I'm thinking of installing floating rotors on my Sportster they'd cost just over $100= each & I'd do it myself I've never had floating rotors are they worth the $ & work over fixed rotors? How often do you have to does this maintainance?
Robert Robb Hi Robert, I would not worry about the rear, but on the front would be a nice upgrade, they prevent disc warp and help with a good clean bite on the disc/rotor for improved braking and reliability. Normal use would see you doing this maybe once or twice a year. Personally I do it two or three times a year, after all, it's you only main way of stopping! RSMF-*RI* Mr B
Mr & Mrs B's Brain Dump Been in contact with the loan company, who have been farting around for the past month, now to be told it's not going to be sorted for another week!!! For F%^$ sakes!!!! [Incredibly RevvedUp(not-quite-yet)Biker!!!]
Nice Job Mr B, it's just another timely reminder to get mine done, getting cold out now though so I'll have to set the Gazebo up, lol, nice bit of graphics work in the video halfway through just incase there are any thicko's out there who didn't get how it's done, does the Busa how a solid disc on the back? mine does, just wondered if it's pretty normal to have solid disc on the back when there floating on the front, my reason for asking is that this is the first bike i've had in years that has had a rear disc brake as daft as it my seem, you have to bare in mind most of my past bikes have been British Classics, cheers bro RSMF RI.
Hi Skeggy, yeah most bikes have a solid rear disc, little experiment with Graphics lol. Yeah I understand all the classics have drum brakes on the rear. :o) Get that gazebo up! lol RSMF-*RI* Mr B
Done mine back in April may do them again. Plus i like the drill very handie was using a socket wrench bolt washers and not slower but did the job. Will look at the drill. ..
Just had an advisory on my motorcycles MOT, it states that there is too much movement on the front nearside disc(caused by lose bobbins). Needs to be replaced..
My KTM service manager tells me if I make y KTM brake fully float I will have all kinds of rapid wear problems. I never heard of this. I want full floating effect so no drag. Anyone agree with him?
wyvernbiker Blimey! - Well you can use a socket or spanner - just takes longer, I know you have no tools, maybe time to start off a tool kit? RSMF-*RI* Mr B
Ive owned busas kwackers hondas yamahas ducatis all with floating and have never had a problem with bobbins in 40 years of riding ive got a set ofbusa discs in front of me now and the bobbibs a solid and dont move they are not supposed to move if the do move forwards on the bobbins I would be worried they are designed to flex not rotate
Some higher end EBC discs have square sided bobbins - search EBC SD system - making this activity obsolete...shouldn't be doing it in the first place irrelevant of bobbin type. They aren't there for side to side movement of the disc. If they are loose they need replacing or new discs...expensive
I genuinely think that you should definitely not do that!! ever!!! They should only be loose when the brakes are very hot.. If you make the bobbins loose when the brakes are cold, they will be too loose when the brakes do get hot.. Well, thats how i learned it..
Utter bullsh*t - your bobbins aren't supposed to rotate. There's a bevel washer in there to allow for thermal expansion and it needs to be very tight. Why do you think EBC bobbins are square and can't rotate? Because there's no need for the bobbins to move, unless you know more than an internationally renowned brake manufacturer?
Sorry you are wrong you do not do this - EBC have redesigned the bobbins to be oval so you can not rotated them this is copy and pasted from the EBC web site - EBC use a patented system called Square Drive or SD for short whereby the “pockets” in the brake rotor blade and alloy hub are milled with flat sides and allow the use of a square or flat sided rivet to connect the parts together. (see photo above). This system offers HUGE advantages over standard rotors by delivering a LINE contact between the components that spreads the braking load over 20 times as much surface area as standard full circle or round brake rotor rivets. link to the site here ebcbrakes.com/articles/best-motorcycle-brake-discs-or-rotors/
When you buy them new, they have freeplay, right,.. My experience is when the bobbins get full of crud and grime, they starts getting incredible noisy,.. Sometimes unbearable.. If you then wants to get rid of noise, you wash them out, spinning them will make that happen!.. Also a freeplay will let less heat into your inner disc..
WTF! This is totally nonsense. In fact i think you are doing more bad than good, someday you will get your precious bobbins out of the disk and your disk will make a mess. This is nothing recommended by any manual, in fact i know by a fact that there is some bobbins with shapes that prevent rotating, this is weird, why someone would do this?
Huh, I've never done that. I started on a cg125 and that had a fixed rotor (04 model). I got a bandit 650 around a year and some change ago and I've never even thought to check the bobbins.

Mr B
Yeah..... Don't do this.
Those are for isolating heat from the outer part of the disc. Stops your bolts shearing at the hubs from radial expansion.
Did this today and it helped a lot.
This procedure isn't recommended by any company. I used to think it was a good idea but after a little research I found out why not to do this. Anyone attempting this should look for arguments against this procedure.
Yeah, just don't enlighten us.

Just use a easy out instead of bolt and washer, quick n easier

ECB have brought out oval bobbings, these cannot move yet are on floating discs which proves they do not need to move.
exactly right
Exactly, the bobbins should not be loose as Matt said, some fucking pricks out there, it's when the bobbins are loose you need to have new ones.
You can tell when he drills them they are oval to prove your point.
It's actually an effective way of cleaning the bobbins & seriously wouldn't go near EBC
Thanks for demonstrating how to do this. Now it's my turn to get this job done.
Motorcycle Extremist Cheers, your brakes will feel much better after!

something to do on the weekend, thank you very much Mr B

Mr B
floating buttons, rotors are for thermal expansion and greater performance, checking the tension and not able to turn buttons on a cold day? try again on a hotter day, its all about expansion
Thanks for this. How freely should the bobbins rotate? I mean is it important that you can turn them freely with your hand?
Holman, no don't do it this muppet will get people killed, they should not be loose, they hold the outer brake disc forgod sake, this muppet needs his bike licence revoked & the busa sold fucking prick.
Don't forget to grease the discs themselves so they glide through the caliper, reducing resistance. Now go out and ride really really fast and enjoy that reduced friction.
😂
I did what you said and my bike won't stop quickly anymore. Do I need to bleed them now?
lot of manufacturers use oval bobbins now which proves they dont need to turn, they are only there for thermal expansion
But they do need to move and be free of dirt to do so. It's called a floating rotor for a reason.
If there are clogged and seized then is there any room for thermal expansion?
Clicking brakes could just be where the pads move slightly in the carrier. With free moving discs, might cause more rattle noise
Nicely done. Thanks for sharing!

Great video. Is there any kind of lubricant you could put on them to stop them locking up or should they stay dry?

What is this for???
I have never seen this in a motorcycle manual....only on UA-cam.
Where can i find this in the manual??????????? Didnt think so.
No of not,! They want you to buy a new set of disc's.. And pads!..
Where could I by that kind of stand to the front of a bike? I've been looking same kind fo stand from everywhere.
Check your local motorcycle shop that sells parts, these are front and rear paddoct stands.
My KTM service manager tells me if I make y KTM brake fully float I will have all kinds of rapid wear problems. I never heard of this. I want full floating effect so no drag. Anyone agree with him?
@@breakwood8531 Mine float they have been replaced with Ducati bobbins. Already " fixed"
Set free your forks and calipers every time your having the wheel of... There are some superb videos on YT, by Mr. Dave Moss..
I had no idea they even needed doing. Is it possible to do without a drill?

Just use an easy out instead of fumbling with a bolt, quicker, easier
Not using WD40 or silicone spray after cleaning?
Just for expansion

ever!!!
They should only be loose when the brakes are very hot.. If you make the bobbins loose when the brakes are cold,
they will be too loose when the brakes do get hot..
Well, thats how i learned it..
Semi floating at best.
Proper full float disks are BETTER
Utter bullsh*t - your bobbins aren't supposed to rotate. There's a bevel washer in there to allow for thermal expansion and it needs to be very tight. Why do you think EBC bobbins are square and can't rotate? Because there's no need for the bobbins to move, unless you know more than an internationally renowned brake manufacturer?

Yes one disc is different so this is wrong for all discs. Fuck off
Hahaa... absolute BS ... why they have to rotate?? Stoopid like a Boss 🤣
The disk has to rotate so they act as bearings??? ... DONT BE DAFT, LEAVE THOSE BOBBINS ALONE.
thermal expansion of rotor by up to 2 mm, do your research
When you buy them new, they have freeplay, right,.. My experience is when the bobbins get full of crud and grime, they starts getting incredible noisy,.. Sometimes unbearable.. If you then wants to get rid of noise, you wash them out, spinning them will make that happen!.. Also a freeplay will let less heat into your inner disc..
No
Utter nonsense.
100% utter nonsense, do not service your rotor like this
Please stop giving bad advice to people. Please.
Fuck this is a dumb thing to do.
Bobbins don't rotate on new bikes./new discs.
youtuber ….WORKSHOP ...will explain why this is utter nonense
this is wrong
WTF! This is totally nonsense. In fact i think you are doing more bad than good, someday you will get your precious bobbins out of the disk and your disk will make a mess.
