Brake pad shim broken/rusted through
Hi all, so my '14 BRZ (127xxxkm, 79xxx mi) lately has been making intermittent squeaking noises while braking, and also when I'm not braking. When I do brake i can hear some sort of grinding, seemingly more toward the rear wheels. I'm thinking, I don't go hard on the brakes, don't drive the car hard often, no rally cross or anything - so how could my brake pads be done?
So I decide to check on the rear brake pads and what do I see... - so much rust in general - rust between the metal shim/backplate of the brake pad with the imprint of caliper piston/cylinder - when i go to try and adjust the shim/backplate, its rusted through and then actually fell apart after So now, i put the caliper back together with my wheel, without the shim/backplate between the caliper cylinder and the brake pad. Questions: - anybody encounter this before? - I assume it'd be safer not to drive the car for now, any idea if you can buy the shim or do I need new brakepads? - also, wtf?

The shim just helps reduces noise. They are not actually needed, I don't run them on my car.

Not absolutely required. They're a vibration damper to help with squealing. Some lube on the same spot can help with this too.
A drill with a wire brush would do a good job cleaning some of that rust up. The rotors look like they have seen better days. Rockauto has some good cheap stuff like centric blanks. Around $46 per. |
