Persistent Brake Caliper Guide Pin Freezing Problem
The lower guide pin on my rear driver side disc brake keeps seizing. I'm at a loss as to how to fix this permanently. Here is the history:
a) Replaced all rear pads and rotors. At the time, the driver side pads showed that they were wearing unevenly (and that the lower guide pin was stuck). As part of the service, I took out the guide pins, cleaned the holes and pins, put guide pin grease on the pins, and reassembled.
b) When I smell burning brakes after a drive (I never drive the car that hard or brake hard), I know that the pin has frozen again. The passenger side is always fine but the driver size lower guide pin keeps seizing.
c) Decided to replace the pin. Went to Subaru dealer and ordered one. Turns out the guide pin does not come with the rubber piece on the end and that it can't be ordered for some reason without ordering the entire caliper kit (ugh!).
*) Ideas for fixing this?
*) What is the purpose of the little rubber thing at the end of the guide pin?
*) Do I really need to buy the entire caliper kit to solve this problem?
Thanks in advance.
