Backing plate?
Hello,
Today i noticed that my car had a noise coming from the rear left wheel. I took it to my mechanic, and he said that I needed a new backing plate. I was wondering if anyone would happen to know what a backing plate is, and where I might be able to find one for my car.
Thanks in advance

OK, trusting his diagnosis, it is the plate behind the rotor to which the parking brake shoes attach. Usually less than $50 street price. Funny that your mechnic thinks that this is the problem, usually just putting in an ebrake kit cures this noise...

Interesting.... I recently was getting noise from a rear wheel in my 95 E320. It turned out to be the backing plate rubbing against the wheel. Took the wheel off and repaired the problem with a few well-placed hammer hits. I don't know how it got out of place. I wonder if your problem is related.

The noise from the backing plate is of a grinding nature since it is the plate rubbing against the hub, due to corrossion. If you clean it and straighten it, the noise may go away for a while. If it needs to be swapped it is a cheap part, very expensive to replace, since the whole brake assembly and the hub has to come off. I changed mine just cutting the plate in two halves and did not have to disassemble the hub, but only the parking brake assembly. After finishing the job I riveted the plate, and it works perfectly since years.
