Squeaking noise on rear brakes

I believe what you are hearing is a squeak when you release the brake pedal. If that is correct, that is due to the shoes sliding across the backing plate as they release. It is fairly common and not a cause for concern, but since it can be annoying, the fix is to pull each shoe away from the backing plate, against hold-down spring pressure, then wipe a little high-temperature brake grease on the three "lands" or raised spots those shoes ride on.

Do not use regular grease as that will migrate around and could contaminate the friction surfaces, resulting in a real squeal when braking. Brake grease is designed to stay where you put it.

This noise is most likely an issue with the rear brakes however you don't have parking brake shoes in the rear. This is a caliper that has an integral parking brake mechanism.

So, we need to replace the pads and rotors and while the calipers are off, we need to inspect them and make sure they retract properly.

I also attached the info below from the manual that will help with doing the same thing.
