I have a groaning noise coming from my right rear brake when applying significant brake pressure, especially when backing down a steep incline. The noise is not a grinding noise like you would hear from a brake pad wear problem.
I have taken the car into two different Toyota dealers without resolution. The 1st said they couldn't find anything wrong and the
2nd didn't even take it for a test drive but said the problem was due to rust that develops on the brake pads in a humid environment (I live near the coast). Both said the Brake system (pads, etc) were OK. The 2nd supposedly cleaned off the rust but the problem is still there.The closest dealer is about 1 hour drive so it's a real pain to keep taking it back for a song & dance answer.
Has anyone else seen or have a fix for this problem?
