Default Brakes make weird BURRRRRRR noise when reversing.

This happened on like the third day after I changed my rear pads. All pads are PBR Ultimas. Third day after changing the pads, whenever I come back from a drive and back into my driveway, the FIRST time I brake the rear pads make a BURRRRRRRRRR type sound. Very loud, and you can FEEL it. Fronts are fine.

What the hell is that? Otherwise they stop flawlessly and the ebrake works.

My car does the same thing after installing Axxis Ultimates which I think is the same as PBR Ultimates? One thing that I noticed that is more than likely the cause is that the rear pads are either too small (from slide to slide) or my rear slide clips are really warped. Try checking those, I can actually slide my pad up and down a good 1/8".

Remove the shims(if they are in there) and spray the backs of the pads with disc brake quieter.

IIRC the Ultimates have those cheesy built in shims, so he shouldn't have the clip on shims on the pads, unless his PBRs were different after all. Regardless, disk brake quieter is a good idea.

So remove the shims completely, or apply the disc brake quieter and replace the shim?

I re-used them off my old pads. Was that wrong?

Remove shims, put on disc brake quiet between pads and shims and reinstall with shims. I use the orange CRC stuff. It's a thick liquid in a squeeze bottle. I also put some between the shim and the caliper fingers where the caliper hits the back of the shim. Basically anywhere metal hits metal. Never had a squeak.

I've been removing the shim's completely for years and never had a noise problem. Prior to that, I had shims shifting and causing all sorts of noise and other problems.

The shims were originally there to reduce noise. Which they do not accomplish. Just something else to get fu***d up

Are your rear rotors Lipped?.>.. the new flat pad might have a slightly larger pad area. casuing new matearial to contact with the outer grove. The pad will wear quickly into the grove, and then be fine.....

I had that on the rear of my 97.. went away after the pad wore in...

Set the park brake and drive a little, to help it grove in.

I am not sure if you should be running the shims with those pads since they have the softer raised spots that are designed to replace the factory shim. I don't think that would make that noise though, it would more than likely be a clicking noise if that was the case.
