I bought a set of rebuilt rear calipers before I knew better. They lasted
two years before the parking brake mechanism started failing.
Now that I know better I rebuild them myself to ensure that the parking
brake mechanism in the caliper is properly overhauled.
Most folks don't realize that the caliper spring is itself strong enough to
push the parking brake lever on the caliper back to the stop when the
caliper is properly functioning....the spring on the mechanism adds an assist.
Failure mode is that moisture gets through the mechanism seal into the body
of the caliper, flushing out what little grease was put there in the first
place, and then corroding the shaft of the mechanism so that it binds
inside the caliper body.
When I rebuild the calipers I replace the seal with a superior $4 USD
transmisson seal from NAPA., and repack the mechanism with hi temperature
synthetic brake grease.
