Title: rotor rubbing after brake job
Post by splash07 on 05/19/12 at 10:54:50

I just finished doing a brake job (stainless hose, drilled rotor, new pads, painted caliper) and after reassembly I am finding that the rotor spokes are rubbing the caliper bracket. I have the spacers in the correct place on the axle, double checked them. I also have a tkat brace installed. ONly seems to rub when the axle is tightened down. Should I just put some more washers/spacers in there?

check to make sure you put the disc between the pads ;D

and the spacer on the caliper side has a lip so it doesn't go into the hole.

yes the disc is between the pads, and like I already said, the spacers are in the correct place.

Well,.. I wouldn't recommend just adding some washers...
Something has changed in the assembly, and you need to find what it is...

I would take everything apart, and try again...

Took the caliper off and the rotor off completely and reinstalled twice now witht the same results. here are some pictures to show where its rubbing.

Loosen off the t-Kat and see if it still rubs. Might be the slider got turned a bit some how and the brace is holding it that way.

I dont think that its the brace because its not rubbing when the axle is not tightened down. In other words with the axle loose and the brace tight it is not rubbing.

What will it hurt to try? The brace should always be loose when you tighten the axle anyway, our you could force the sliders out of alignment and cause the forks to bind a little.
The order is axle, brace, then pinch bolt, with the front wheel off the ground.

It's something about how you have the pads in... Did you get those tin springy bits in right?...
no. 3 and 10 on this parts list...

Loosened the brace and tightened the axle, still rubbing.

Pretty sure the springs are in right, but remeber its not the pads rubbing its the rotor spokes rubbing the backside of the caliper bracket. Thanks for the quik responses, this is driving me crazy!!

I don't know rotor spokes...
Do you mean the actual wheel spokes?...

Edit... Oops...I think I know what you mean...

I'm gonna' go stare at my wheel for a bit, and try to figure it out...

you can see here what I am talking about, where the paint is being rubbed off.

I just looked at my bike. The axle spacer with the shoulder goes on the brake caliper side - with the shoulder touching the fork leg.

Show me a pic of the rotor side wheel spacer...

Me thinks they are mixed up... the one with the flared outer part should be at the rotor.
PS.. gotta' do a couple errands... be away for an hour... ;)...

OK another theory. There is a lockwasher and a washer for each of the two bolts holding the caliper bracket on the fork slider. Currently I have the lockwasher on one side of the fork slider and the washer in between the fork slider and the caliper bracket. Do both lockwasher and washer go on the same side?

Ive got a washer between the carrier and the fork. Is that washer supposed to be on the outside with the lockwasher?

Title: Re: rotor rubbing after brake job
Post by verslagen1 on 05/19/12 at 14:15:06

that's the carrier rubbing. should be no way to do that.

look at the carrier and fork, shouldn't be anything between, no air gap.

By Gumby,.. I think you've got it...
Did you see this?... both washers on the outside...
(now,... pretty up those fancy rotors again before you put it all back together)... ;)...

I had #17 in between the carrier and the fork slider and #16 inbetween the bolt and fork slider. I moved the washer #17 over with #16 and that solved the problem. Axle tight and no rubbing. Now I have to go repaint the rotor.

Thanks everyone for the help. Go Team!!

Lock washer under the bolt head then then flat washer underneath that. The caliper bracket goes straight on the inside of the forks.

BTW in the pic that shows the pads, you put the pad that was previously on the piston side on the opposite side. You always wanna put the pads in the same spot they were before, unless you use new ones. They are "broken in" so to speak. If you swap them, you can run into issues as they do not wear identical one both sides. They may appear the same in most cases, but not 100%.
It shows the piston imprint circle on the back plate, so it was on the other side previously.

Too many stationary parts !! ;D

The old pads are only there while I am taking the wheel off and on so much, I have new pads going in during final assembly.

I've been thinking about painting my caliper for months.. suddenly I'm very inspired...

Did you put the washers between the caliper and the fork mount instead of between the fork mount and the head of the blots??? If did that on mine I would get the result you have. Looks like the caliper is too far to the right of the left fork.
