I have a pair of rotors that seemed to have gotten heat glazed. I'm getting a bit of squeal from the brakes at low speeds. I'm guessing the pads are glazed too (havent pulled them out yet).

I heard once that a trick in removing glaze is using sand paper. Using a grit paper and then wiping down both pad and rotors with brake cleaner. Can anyone confirm this?

 

Try scraping the pads on the ground, or hitting them with the belt sander.

As far as the rotors, you can try 1500 grit sandpaper and work your way up 2000 or so.

Low speeds make me think it could be the hardware too, try grabbing some brake lube and going to town on the pins, in between the pads and the shims, and in between the shims and the piston. Also throw a little on the piston rubber.

Hopefully that will get rid of it, but my Z squeals a lot at low speeds too and mine aren't glazed, and I slobbered the heck out of the brake lube.

Just finished a new install though, and no squeal, yet. :crossingfingers:

 

Don't scrape them on the ground, Jeez dude.

Use 220 grit Garnett sandpaper or a coarse (brown) Scothbrite pad and flush with brake cleaner or Acetone. Use a sanding block or a 3" Rowloc wheel. Do not use aluminum oxide sandpaper on the rotors or pads. The oxide will imbed in the rotor or pad surface and make it difficult to get a new layer of pad material applied evenly.

 

Great, thanks for the info!

 

Didn't know that about the sandpaper, good piece of information there.

Good luck man, not a fun project
