Rear Brake calipers - 200Q20V

[alan cordeiro]

Peter,

I had a similar experience, I bought a set of rebuilt calipers
because the parking brake levers were totally stuck. They lasted
less than a year, and I got a second set free under warranty.

Well the second set started sticking abut two years later,
so I decided to do the job my self, yes, I filled the rear cavity
totally full of Mobil-1 synthetic grease.

So far its been one year,

Alan
