I don't normally comment on these videos, but this rot just takes it to a new level. Spin the wheel, stops in 1/2 a turn, oh its substantially better. Does he actually believe what he is saying?
Can you please stop having a go at this amazing expert. I use his videos to set up all my bikes and once I am out of hospital after the latest crash I will be using the insider knowledge to set up my wheelchair ,although my last one did tend to go round and round in circles. My mate and I think so highly of him we reverentially call him Mr. rubber head due to his comprehensive knowledge of tyre wear reading.
I respect Matt for not touching the setup videos, he never claimed to be a vehicle dynamicist or race engineer so him commenting on that would be about as useful as Dave doing it 😂
What the fuck is he trying to confuse, is it me perhaps, pity he doesn’t try and balance helicopter blades, it might be that far out he loses his head .
All new!... discs and pads!... but I want to hear Dave talk himself through it, like a personal tutorial, because that makes me feel all warm and fuzzy inside
I have watched both you and Dave's videos for years. Learned a great lot from dave's tire reads, fork setups and maintenance, he knows his stuff. To be fair this is not one of his best videos but i assure that he as alot that is absolute golden.
@@dirtygarageguy We clearly have different ways of interpret things. All I said was I have been watching his other videos that are great. I now know how to read tires, understand how the suspension work with all the settings and how to properly service the forks. All this I couldn't have learned by my own. Though I'm not a pro by any means, but to the degree that I'm able to setup my race bikes much better. Made me even a better rider having a deeper understanding how the suspension works. He sure has helped me a great deal and was worth to buy his subscription. Maybe you should really see his other videos and make videos of them!
@@dirtygarageguy Those playlists, any pick. Ofcourse most of them are just clips, you need to get his subscription to get the full videos obviously. But I get it, most people doesnt give a shit about suspension settings and tire reading. Its just for the passionate ones
What a special special man. Truly the Moss is an expert of the higest quality. Expert of nothing of course. He is the ruin of bikes and any biker that listen to him
I think Dave may have got his mechanical knowledge from Working on Bicycles the pulling the brake whilst tightening the Caliper is something you do on old center mount brakes
He has made sounding knowledgeable when you are talking utter shite waffle an art form. UA-cam gives a platform for any old bullshitter to peddle their pseudo engineering babble to the masses. He sounds very convincing as he moulds waffle into scientific data. UA-cam, the gift that keeps on giving..
What the f**k was that clunking noise when spinning the wheel with no callipers ? Sounds like a collapsed wheel bearing race. That wheel would be straight back off in my shop.
believe it or not, there's actually a factory issued communication, regarding tyre runout on a specific model piaggio 400cc scoot, because of frequent complaints from customers about wobbles. if it's more than a specified range, we replace tyres under warranty. quite funny is that
6:48 I'm not even sure what he's trying to do. For it to be grabbing more in one spot than another, it's either the disc or the rim warped. Remove the callipers and fix a pencil to something, with its point close to disc. Spin the wheel. If the pencil gets closer to the disc then something's warped. Do it again for the rim. If the pencil doesn't get closer, it's the disc that's warped, if it does get closer then the rim is warped (or the bearings are screwed). Takes a few minutes to do this.
Is this a “David Brent the office” style U tuber? As in I’m acting like an idiot but trying to make it look like I’m not because this guy just cannot be real!
I'm betting he has hammered, or pressed, in the bearings wonky and they're not parallel to each other and the rim, which might explain nasty noises. You would get inconsistent runout like this if they were, especially as it's mirrored in the rim and the disc. If there were runout in just one part then I'd say it's bent, except it's consistent in both. It is possible to get them really out of shape and keep going. I've dealt with the aftermath of someone getting it slightly cockeyed and just going to town with a hammer to get the bearing in
'Rodors' are impossible to fix. A local tyre fitter employed an idiot who though it was a good idea to bounce brake discs off of the machine and bent them, as he did it to the floating discs on my RG. The first solution was to send them for straightening and it doesn't last long before they're out of shape again. They ended up being replaced
So the wheel he changed the bearnings in looks to be twisted. OK we will just ignore that. Let measure a pile of stuff and that has nothing to do with anything and pretend we got some sort of results which fixes a non problem to start with. 😂 we will swap one router from one wheel with another wheel because if both roaters have a different thickness the master cylinder will know this and won't apply the same pressure to the pads, because he's a Kent. Hey dave was all 4 rims fitted with the exact same brand of discs? Where they all fitted at the same time? Have they done the same laps or mileage? Did you check they wer all free floating and not rusty or sticking from lack of use maybe? Dell has finally lost the crown. 😂
You could pull the callipers off the forks and pump them till the pads touched and you would still get the 75mm at the handlebar ( providing enough fluid in system) . This test is utter bollocks.
I might need to return to this and put on closed captioning, i don't know whats worse, Daves voice or that grinding noise. I may need Dave to look at my bikes, as neither one make that sound, could there be something wrong with my bikes?
Changing the wheel rim which will removes the problem of him not aligning the axle initially correctly , He would do better to just use the the correct technique to align the axle than just change the rim . Rolling out the professional bike un-benderer is hilarious. Old Stock warped discs or bent wheel take your pick.
Did he check how straight that how straight that spindle is on the wheel balancer because it spins on bearings of the wheel balancer, are the spacers/clamps tight enough? The clearances between the spindle and spacers might be too big and the locking bolts could be spaced opposite of each other. In my opinion those balancers are ok for just balancing the wheel, but then the bearings could be crap even on a brand new balancer and give a false reading. I changed bearings on mine straight away because they were full of thick and dirty grease from factory and they wouldn't spin evenly.
I've always doubted a DTI can properly measure disc run out on the bike as the disc is sitting on bobbins which allows greater movement than the run out tolerance. I wonder how many good discs get replaced unnecessarily.
Jeez. Right from the start i was thinking just get a dial indicator. Measure for wobble sideways on the wheel. If it is unacceptable fix it or replace it. They probably cant be fixed. Do the same for the rotors, but replace them if out of spec. No way to fix. End of story. He has to waste time on unneccesary nonsense. All those wheels probably need replaced. Guaranteed there is unnaceptable vibration which only gets worse as speed increases.
No. The only difference a disc can effect is if it is warped it can push back the pistons as the wheel rotates so the 1st pull of the lever has more travel.
Over 99% of this video is Moss just waffling on about nothing relevant to the issue. This guy just does not seem to know even the basics. The calipers share that same hydraulic pressure line from the MC...so they will equalize their movement against the rotors even if rotors are slightly different thicknesses. Pads can wear at different rates not only across the two rotors but also on each side of one rotor...again all handled by the caliper pistons & pressure equalization effect.
He over complicated the shit out of it with some crazy weird tests Matt the buttons on the rotor assembly could be sticking You have to keep an eye on them Sometimes they have to be cleaned out The brake dust and road gunk builds up in between the buttons and the assembly and keeps them from moving freely If they can't float to center The rotor is gonna bind against the brake pads as it spins I usually push the brake caliper in with my knee to collapse the piston (s) to see if they have any binding Sometimes a caliper just need rebuilt or replaced if They have a tendency to drag That is if it's not a warp rotor or crud on the rotor mounting face or too much run out in the rotor mounting face
when a brake disc starts to get hairline cracks that start at the drilled holes and go upwards and downwards from the hole , why does this happen ? I mean why do they always crack at the same place
@@dirtygarageguy excellent , but what is the reason for nearly all cracks start at 12oclock and 6 o clock , and I've never seen any at 3oclock or 9 oclock , I think its something to do with the crack is easier to form here than go sideways and curve with the disc
Which direction does the disc expand in? Radially, so the stress within the meaterial and between the grain structure is going to cause cracks that run perpendicular to that force.
44:30 dave you wet wipe the air in your tyres isnt solid, do you really think that 2 or so atmospheres of air in your tyres with 300kg over them is going to be stronger than half inch of rubber with a 2mm "bulge" causing you to be bouncing up the road looney tunes style or have a speed wobble😂
All i saw was a bloke called dave talking bollocks😀
Dave is the funniest.
Funnier then Del or Ginger.
I don't normally comment on these videos, but this rot just takes it to a new level. Spin the wheel, stops in 1/2 a turn, oh its substantially better. Does he actually believe what he is saying?
Dave moss special!..oh he's very special. Four letters, begins with m, ends in ong.
He claims he’s a suspension specialist yet seems to know the square root of fuck all about suspension
I thought he was also a tyre wear expert which is why my friends and I call him mr. Rubber head.
Feck me if you suffer from insomnia ,just watch "the moss" 😂
It's taken me 2 weeks to get through this for that reason
@Double Daves
Just measure the disk at a point where the pads don't contact to know how thick it was when new.
Hilarious I watched this and an image came to mind- a dog chasing its tail 😂
I'm sure Dave was saying "apoplectic", which means full of rage because he was being a fecking moron for not using a torque wrench like he should have
Or he was having a stroke. I think it's that one lol
Got to be honest, as you can tell, I've never heard of the word, but neither has expert Dave lol
@@dirtygarageguy 🤣🤣🤣

"right there, so we can do it in centimeters... So, 62 millimeters."
I feel like watching a fever dream, like nothing makes sence
I'm 14 minutes in and I'm betting he goes for the drill on the disc floating rivets routine.
Gotta say it,"click"..lmao! If he he wouldve said twice it wouldve been more accurate, see! Just havin a laugh!
Probably missing a wheel spacer.🤪

welcome to beyond 2000, this is the internet, with your host, dave moss.
Love the irony of your catch fraze to Dave Mossplaining, makes total sense :-)
Witness a fallen idol Dave Moss turning

Yep, I noticed the same.

This is a good video in terms of moving pictures.
think he should just take te discs off and go for a rip. problem solved
6:48 I'm not even sure what he's trying to do.
For it to be grabbing more in one spot than another, it's either the disc or the rim warped.
Remove the callipers and fix a pencil to something, with its point close to disc. Spin the wheel. If the pencil gets closer to the disc then something's warped. Do it again for the rim. If the pencil doesn't get closer, it's the disc that's warped, if it does get closer then the rim is warped (or the bearings are screwed). Takes a few minutes to do this.
The service manual will state the maximum serviceable rotor and wheel run-out values.
We've had machines at work, particularly leased ones that can't do the same thing twice, & that's with all the user adjustable settings left the same.
I was losing the will to live 😂
Braking force = loss in dramatic amount 🤣
Is this a “David Brent the office” style U tuber? As in I’m acting like an idiot but trying to make it look like I’m not because this guy just cannot be real!
Dave moss is trying to get scientific results with terrible back yard mechanic practices
11:35 what's that knocking sound as he rotates the wheel? 🤔 It should be beautifully smooth and no knocks.
Bound up bearing?
I'm betting he has hammered, or pressed, in the bearings wonky and they're not parallel to each other and the rim, which might explain nasty noises. You would get inconsistent runout like this if they were, especially as it's mirrored in the rim and the disc.

Rhoda needs to stop pushing the pads out naughty girl.
You could pull the callipers off the forks and pump them till the pads touched and you would still get the 75mm at the handlebar ( providing enough fluid in system) . This test is utter bollocks.
He's doing an Italian-style pronunciation of Rosso. Maybe he's actually Italian-Manc-American. 😊😮😮
I’d rather let my cat check my bike over.
apoplectic is what he meant to write, "overcome with anger".
Are we sure that DMT on his shirt IS actually "Dave moss tuning" instead of his favourite type of drugs?
I might need to return to this and put on closed captioning, i don't know whats worse, Daves voice or that grinding noise.

29mins in. Im off to bed.
Thanks matt
You need a fake soul patch to do Dave's videos.
There is a box in the background that says "butcher box" is that where he gets his knowledge from 🤔
I've always doubted a DTI can properly measure disc run out on the bike as the disc is sitting on bobbins which allows greater movement than the run out tolerance.
I wonder how many good discs get replaced unnecessarily.
Can it? Have you ever tried to shift a disc laterally?
@@dirtygarageguy Yeah, OK. I just had a go, it moves much less than I remember!
It's not just how much it moves, it's how much force vs a DTI
'Our workshop manuals now include links to sound files online, that can help you diagnose front wheel problems:....
Is this guy for real? WTVF!!!!
Roader - and never mentions brake disc.
I actually feel like I have learning difficulties when I watch a Dave moss video, remember not all Daves are wankers 😂😂😂
Haha he don't even pretending 😅😅
11:43 I'm not an engineer but when you spin a wheel and it makes a knocking noise like that, something's wrong.
Dave,put some grease on them spinny,shiny brake thingy, that'll sort em out👍👍
Measure disc runout with a dti ffs
This is how woke engineering works....with the feelzzz
Not only can [Dave Expert Legend Engineer Moss] feelzzz he is able to hear for concentricity and smell it.
The wheel would spin much easier if you took an angle grinder to the brake pads.
Jeez. Right from the start i was thinking just get a dial indicator. Measure for wobble sideways on the wheel. If it is unacceptable fix it or replace it. They probably cant be fixed.

Why is he fucking around just take Brock’s advice and grind off some of the pads.
Seriously this guy is fookin eeedgit
Is he charging for this job?
Have you changed live streams to Sunday's Matt? Or just no live stream this sat. Thanks
Yes lol
@@dirtygarageguy epic!
He could of made this video 5 seconds long and said "he fooked up, Didn't do the job properly In the first place" the end.
What on earth is this man doing, if owts out of spec causing weird rubbing it's probably his dogger pads
I can see the rotor isn't straight. I don't think it's mounted properly
Mossy does seventh Sigma cause he’s 1 better than the others 😉
Moss doesn't have it centered on the spindle.
What did I just watch and what was the point? All I heard was Moss flavoured word spaghetti.
Would the thickness of the disc cause the brake pressure to be diffrent
No. The only difference a disc can effect is if it is warped it can push back the pistons as the wheel rotates so the 1st pull of the lever has more travel.
Matt, you changed your hair. The ginger was sooooo you.
That tire looks deflated like the bead is not set.
I have successfully worked on motorcycles for 55 years and never resorted to this baffling Bullshite. Am I missing something? NO !!!!!
Wobbly wheel surely bearing

For christ's sake...won't someone send him a DTI !
It's a 5 min job to check disc and wheel run out
Pads needing Brock modification😂
3:33 Tyre.
I suppose I should be grateful he's not a yank, calling the tyre a wheel.
Hilarious, the guy is so pretentious it begs belief.
He over complicated the shit out of it with some crazy weird tests Matt the buttons on the rotor assembly could be sticking You have to keep an eye on them Sometimes they have to be cleaned out The brake dust and road gunk builds up in between the buttons and the assembly and keeps them from moving freely If they can't float to center The rotor is gonna bind against the brake pads as it spins I usually push the brake caliper in with my knee to collapse the piston (s) to see if they have any binding Sometimes a caliper just need rebuilt or replaced if They have a tendency to drag That is if it's not a warp rotor or crud on the rotor mounting face or too much run out in the rotor mounting face
The way he swaps T's and D's in words when he talks does my bloody head in. Cant stand the way the guys talks...
So clearly, there is something different here @19:40
yeah dave, you tired, i hear you breathing...
pull it a bit harder, youre arms cant handle it...
What astonishing bollocks. If the wheels and "roders" have run-out, swapping roders for a 0.1mm difference is a complete waste of time.
Disk run-out takes a lot of rotation to do its job, Bullshit aimed towards his viewer IQ.
Dave is psycho,i bet all the cents i have
when a brake disc starts to get hairline cracks that start at the drilled holes and go upwards and downwards from the hole , why does this happen ? I mean why do they always crack at the same place
obviously this happens on well worn discs , or discs that have gotten very hot on trackdays etc...
Because the weakest part or anything is where there's nothing. The edge are stress risers. The contraction and expansion stop here.
@@dirtygarageguy excellent , but what is the reason for nearly all cracks start at 12oclock and 6 o clock , and I've never seen any at 3oclock or 9 oclock , I think its something to do with the crack is easier to form here than go sideways and curve with the disc
