You've changed your brake pads and proceed to reinstall your brake calipers, i.e. mount them back onto the forks. Is there a process involved? Why, yes, there is.

I have been educated on so many different motorcycle tuning video's thanks to Dave, I really want to thank you for all the helpful info that you given over the years. By far, one of the best "technical teachers" I have seen
Thank you very much for investing in yourself and our content here at DMT.
I've watched about 4 of these videos now and learned so much!! great content
Great video! May I add that if an inconsistent sound is heard it may be caused by dirt/corrosion on the surface where the rotor mounts the wheel. Just a tiny amount of dirt/ corrosion will cause a significant amount of run out at the braking surface.
If this has been happening for some time the rotor thickness will have worn inconsistently, giving the impression of a warped rotor.
You sir are a legend
Top tip, thanks Dave 👍🏻👍🏻
Very useful. I just did a brake pads change and works as described.
Never knew about this.. what an awesome bit of wisdom, thanks!
came here wondering if this thing I do with my road bike will work here, too. got more tips in the process! nice one Dave :)
It's true: you do learn something new everyday ☺
Great video! Thanks for making it!
This may be a silly question - but do you do this before or after you've bled the brake lines? I'd assume after so youre getting equal piston engagement, but before, the pistons are withdrawn into the caliper.
Thanks for your tips!
Just subscribed to the channel dave , recently bought a Suzuki gsxs 750 ,im hopeing to do most of my maintenance myself, i take it that unless specific to a certain bike that the knowledge you share is good for any bike , cheers looking forward to seeing more vids
Thanks for subscribing! There are a lot of general principle videos here that translate to the vast majority of motorcycles.
Wasn't aware of this. Cheers!
because it's bulshit, not true, just invented a new way to be funny ;)
hey dave does this apply only to monoblock type calipers? I have a Ninja 650R with Tokico calipers, they bolt up differently to the fork tubes!
I was like ‘ on the other side what for ?’ 😂. Amazing bike
Ingenious brother
Great tip.
I love dave
Thank you dave...
the fact this vid only has 720 likes is ridiculous how do 39k people not upvote your content when its invaluable.
Thank you for your support on this video. They feel this is a pointless process for them personally can be the only reason. Shame, but there it is.
Now that the option to down vote content has been removed, I feel that has made up votes relatively meaningless, hence I no longer put likes on videos.
You could get a sense of ratios before, now you can't, so I no longer engage with that system.
I knew I seen this technique somewhere!! I had to do a CZcams search.
Well FML🙃 mine does this and thought I had a problem.cheers
I want to swap out my 6 pot 2000 zx9r e2 calipers with some triumph sprint rs 955i 4 pot nissins with the same mount bolt size but I was wondering if I'll have a problem with the caliper sitting centre on the disc or doesn't it matter as the pistons move freely , or is there a way to measure caliper is centre and put a washer there if needed , all the forums seem a bit vague on fitment and don't want to spend the money if it's a problem , any advice would be much appreciated thanks
1. Are bolt centers identical? 2. Is the caliper width the same? 3. What size rotors are on both bikes, so are spacers required to set the caliper distance? 4. Do brake pad dimensions for overall size compare favorably? I'd start with these questions prior to spending $$.
@@catalystreactionsbw great advice thank you 👍🏼, the mount holes are both 90mm and the discs differ by 10mm I'll find out the width, is there any tolerance with width and disc size at all
finally,a tutorial with no bullshit and like or subscribe
Is this the same process for non-radial mounted calipers?
Yes it is.
About how many rotations should a front tire spin before coming to a stop on its own? I just had my front tire replaced by a local shop and my brake lever feels a bit different and after putting the bike on stands and giving the tire a spin, i get about 2 rotations before it comes to a rest. Ty for your time
When done correctly, 3 to 5 rotations.
Although all wheels are different, some things to consider are; Are your wheel bearings dirty or worn? Did you improperly under-torque your axle and the shop torqued it properly (less spin)? Did they reposition your pistons, or clean them, and seat your pistons properly (like this video shows)? Did you have new tires installed? Are rhey heavier tires?? Several factors are at play. Hope you figured it out.
I just painted my bike and when I put the rear wheel and caliper back on the wheel don't want to spin.....hoping I don't have to take it all back apart......thanks for any help or suggestions.....there are brembo brakes on the front but not the back.....it is however a caliper and not a drum.....
Check you have the spacer between the sprocket hub and the wheel inside as well as both spacers on the outside. Yes, you have to remove it to check.
Does this apply to axial calipers aswell?
Yes it does. For telescopic forks, calipers need to be pushed "forward" due to free play and then bolted into place.
Does this work for the calipers bolted at 90 deg to the rotor too? Or just the inline ones on modern bikes?
This works for all calipers bolted upside down forks. Telescopic forks set the caliper in one location.
@@catalystreactionsbw This comment makes no sense. USD forks are telescopic forks, just like RSU/conventional forks are also telescoping.
USD forks commonly have radially and axially mounted calipers, it's not either/or. A brake guru should knows these basics, at least
@@shinyribs2178 Thank you for your contribution and points of accuracy.
When spinning the wheel there is a faint audible fast clicking noise you can hear. I was wondering if this is normal? This noise started when I married a set of M50 brembos with Vesrah Sintered Pads.
Check the rotor on the carrier for free play, then watch each brake pin to see if it moves when the wheel spins
I got that click on original CBR600rr rotors, its the play between the rivets, its actually good that the rivets dont bind and have room to expand, otherwise you get pulsation feedback when the rotors heat up and expand.
Hi sir, I have a problem with my rear brake, it seems like it was not biting at all. I tried to spin my bike in the friction zone when I used my rear brake it wasn't even stopping. What should I do. I just bought my bike brand new last year. Thanks!
Hello Mario. Please check the oil volume in the inspection window or the reservoir. Do you have oil in the system? If your rear brake is not working you should have that covered under warranty. If not, a simple brake fluid bleed will get the pressure back. Note tat we have a video to bleed rear brake calipers when it is upside down at the bottom of the rotor.
Cheers 👌
hmmm. my rc51 front wheel only makes about 1 revolution when I spin it with a lot of force. rotors are straight and disk is centered in the calipers. what should I do?
Service the calipers. Clean them, clean the pistons, and use red rubber grease (cheap on amazon). Inspect pads. It sounds like the pistons are not reseating fully and that would be due to dirt.
czcams.com/video/0sHQfnbf9t4/video.html is a brake caliper cleaning video that might be helpful.
Will it work on single sided piston caliper?
Fork upside down forks and radial calipers, yes. With telescopic forks no.
fucking brilliant...thank you Dave~
Why does the wheel stop.so quickly? Are braking pads resting on the disc? Will that not produce heat and ware the pads out?
That is one cause, the other is the leg that the axle goes through is not set correctly.
@@catalystreactionsbw believe the question was referringto the video demonstration "Why does the wheel stop so quickly?" *It was because you quickly squeezed the brake lever to seat the pistons against the brake rotor.
The bike is on stands so the wheel has very little rolling resistance other than normal drag. I apply the pressure quickly to seat the pistons against the rotor so the calipers align to the rotor. I also clean the brakes VERY regularly with a toothbrush and soapy water.
Does this work with a single sided piston brake caliper??? I have one of those old brakes and wonder if I can do this same method???
Yes you can as those calipers move back and forth, so in doing this you will be able to get the caliper perfectly straight to the rotor.
@@catalystreactionsbw Thank you!!! I was waiting to hear from you!. I will do it now haha!! Can't wait to get rid off those singing disc! 😀😀😀
dose the same apply for the rear brake
The rear wheel is set by the adjuster for lateral straightness. If it is off, the rear brake pads will wear diagonally. So in this case, no.
do you do that with the rear brakes? they have a guide from the swingarm
There is peace of mind when you know the rear caliper is centered on the rear rotor when brake is applied, then torque your axle.
@@catalystreactionsbw well is this really necessary to do on the rear calliper since it has calliper sliding pins which allows movement left and right
@@Fordahord1 If you believe that greasing the guide pins is enough, that is fine. I you see diagonal wear on the brake pads, cleaning the pistons and holding the brake on does not hurt in being thorough.
@@catalystreactionsbw usually I put something between the sprocket and chain to make sure that the chain adjusters are all the way forward. That means that I can’t spin the wheel and apply the brake. I guess I’ll have to choose between one or the other
@@Fordahord1 Just another set of hands to be recruited to coordinate brake lever with rag/screwdriver in the sprocket. Might cost you lunch but worth it :)
On Hydraulic Disc Brakes on a bicycle, when they are aligned the wheel rotates completely free... but here, not as free, why?
Pads will always have a little bit of friction. Pads are larger as are rotors so there is more friction and resistance. Done well, the wheel will spin 5-6 times and then lose inertia
I really don't understand why this is necessary in axial calipers. I mean, this calipers cant be aligned. When you adjust the axial bolts, they get always in the same position looking the bike from the front. Adjusting the screws with the brake activated, the only thing that it generates is that it hardly changes its position (due to the clearance of the holes and the caliper screws) but looking at the motorcycle from the side, that is, it does not impact the alignment (which is what we see from the front)
Please, someone correct me if a wrong. We are here to learn to do things well but in an efficient way (I mean not to do unnecessary things) 🙌
Hello Tomas. Thank you for your comment. I go this route because it makes me feel comfortable that I have done the best I can to make everything correct to my way of thinking. You can certainly have a different approach based on your understanding of engineering and optimizing/streamlining your work flow and time with your motorcycle. Please do so - this just serves as a thought provoking video and me sharing my approach.
My problem is the caliper bolts cannot mount to the fork because it’s not aligned.. the caliper bolt holes are about 1/2” towards the wheel. I have tried pulling the caliper back towards me to get the bolt aligned but no luck. Any advice?
Do you have the wheel spacers mounted correctly? Is the direction of the wheel correct?
@@catalystreactionsbw the wheel spacers are in, what I can’t tell is what way they go in, I’m doing it to the best of my knowledge according to the service manual.
@@kodyking3090 If the spacers are in and nothing lines up, switch the spacers around.
@@catalystreactionsbw turned out the dealer mounted the tire backwards. Wheel is one directional and one rotor sticks out slightly further than the other
@@kodyking3090 Great catch!
best advice ever thank you so much that fixed my problem thanks again
Glad that was very useful and thanks for posting!
His name is Dr. Dave Moss.
Can it be done without lifting the bike? I'm thinking about walking with it, hit the brakes and then adjust.
A side question. Can (is it possible) the pads or caliper be set further apart so that the pads don't touch the disc at all?
Appreciate your content - greetings. :-)
It can be done that way by dragging the brakes as you push it. Then hold the brakes on.
Are you asking if you can set the brake with minimal drag on the wheel so the wheel spins freely?
My bike still same, skipping
this dude is high :))))))))
don't use the torque wrench just do that shit you did :)))))))
You didnt listen closely enough.
He said you can "torque them afterwards" meaning after you have the calipers aligned properly you can go back and torque the mounting bolts to what ever is the torque value specified for your bike. Just in case you were not aware, there is a torque spec for those bolts.
lol, you've got no idea who you're calling high mate
