I swapped out the front rotor and pads on my Hayes nines and am getting some serious rubbing (un-ridable). This is on a 2003 Cake so I'm going from the old style (flat rim) rotors to the v-cut. Does anyone know what the problem could be? Do I have to adjust the calipers or something? It's not an alignment issue... its getting even and constant contact from both pads.

Thanks!

slide a bussiness card on one then both sides of the rotor. slide into the caliper and squeeze the lever. this should open up the gap between pads and rotor.
hope that works.

did u reset the pistons before dropping the new pads in there? if not, give that a shot. chances are they crept out because of the pad wear of your old pads, so now with the new pads, there is more material taking up the space that once let your rotor spin through.

If the pads and rotors are new, rubbing on both sides is normal. Just ride the bike. After a ride or two (depending on your ride), the pads should be broken in, and you should have plenty of room to adjust the caliper - if needed. You could also ride around your house and do about 30-50 hard stops. I never spend too much time trying to align the calipers with new pads and rotors.

thanks guys. i'll give it shot when i get home from work. i knew there was probably something i missed. the notes that came with the pads said to push the pistons back just to make the pads easier to install. i pushed on them a little bit but didn't give it much effort since the pads clipped right in easily enough.

Hey Aaron you need to reset the pistons for sure.
All you need to do use something soft like a plastic tire lever and pry them open all the way with your 2 mm adjustment screw on your brakes backed out. then put it all together and it should not rub anymore.
Bring it over if you want and I will tune it up for you.
Oh wait it is a GF cake I can touch that ha ha J/K . I will tune it up for you .

Just reset the pistons and you should have no problems! Sounds like you just didn't set them al the way back.

Edog · 07-09-2007, 03:10 PM

Try resetting the pistons

LBmtb · 07-09-2007, 06:40 PM

Hmm, maybe try resetting the pistons.

Gabriel Zink · 07-09-2007, 06:50 PM

While resetting the pistons don't forget to apply a drop of dot fluid to the piston for lubrication.

Pain Freak · 07-09-2007, 07:24 PM

If it was me I think I'd just rest the pistons?

Waldo · 07-09-2007, 08:38 PM

I've heard of a process some call resetting the pistons...

btw: if you've bled the system/added fluid with the old, worn pads in place, you might want to repeat the process now that you have fresh, thick pads in.

yep, that did the trick. thanks everyone.

Did anyone mention resetting the pistons? IDK just a thought.

SSSSHH!!!!

Come to think of it, those were all-new brakes on the M3. I couldn't slow down as much as I wanted to.
