I just changed front pads/rotors 91 stock std hatch, broke them in for a half hour, and I am getting rubbing that started off loud and now is just a light "shick shick shick" rubbing sound.

1. the sound is def coming from front driver side, and i can't hear the pass side.

2. old drivers side pads: outer 2mm/inner 6mm

3. greased the caliper pins.

4. sound returns after heavy braking, then goes away only to return again

5. likely the pins or potentially the piston?

i have read that uneven inner/outer pad wear is indicative of dirty/dry pins, not the piston.

thanks in advance!

 

bump.

 

have you checked to see if the metal splash shields behind the rotor are rubbing at all?

 

Were the rotors replaced/turned when you replaced the pads? Did your pads have shims or backing plates on them? Were those reinstalled? Have you tried some brake lube/brake quiet on the backs of the pads/shims?

 

1. put in new rotors

2. old outer pads only had backing plates

3. new inner/outer pads have backing plates

4. i did not lube behind shims/pads

slammed: i did not check to see if there was shield rub, since the sound goes away for a while , and comes back after hard braking

q#1: lube goes between the shim and the pad?

q#2: could the prob be that the old inner pads were not shimmed, and the new ones are?

thanks again

 

You can generally lube any surface where there's metal to metal(or pad to metal) contact, except where the pad meets the rotor of course. It's generally a good idea to retain the shims/backing plates if your pads came with them originally, but I've run without them for a long time with no problems. Lube/brake quiet usually helps with brake squeal and chatter, and it's pretty cheap, so you may want to give it a try. However, if the noise you're describing is more of a constant rubbing sound, then I would look for contact or interference elsewhere. If both your rotors and pads are new, it may just be that they need some more time to fully bed in.

 

Thanks for all the input, I'll just wait and see.

 

One thing to check for the Northern States and Canada. Rust will accumulate under the fitting kit (metal springs that touch the pad ears). Pull off the fitting kit off the caliper bracket and file down any rust under. If too much rust builds up the pad will lock into the caliper bracket and drag on the rotor.

Had a serious issue with my rear pads, did everything and couldn't figure it out till someone mentioned this... yep tons of rust, file down now everything is good.

 

after initial 20 minute break in, i got in the car today, and no more rubbing.

i guess they're broken in, because i drove for a couple of hours and no rubbing!

you guys rule
