Subject: Re: dragging caliper
Content-Type: text/plain; charset=UTF-8
I'm not sure exactly which type of caliper you have on an '85 so I'll make
general comments. There are two main spots where corrosion can cause a
caliper to seize up; the piston itself and the caliper bolts or pins that
it slides on. If the pins are sticking, but can be forcibly pulled out,
the rust can be scraped and sanded away and the holles cleaned out. A
round file may be helpful here. Relube with caliper grease.
A piston that is sticking can often be loosened up by simply moving it
back and forth a number of times after appying some penetrating solvent.
With the caliper removed from the disk, you can extend the piston by
pressing hard on the brake pedal. You must prevent the piston from blowing
out completely by placing pieces of wood of the proper thicknes where the
disk would be.
Then shove the piston back in using a big C-clamp or welding clamp or a
special tool baorrowed from your FLAPS. Repeat this process as many times
as you have patience for. Keep an eye on the fluid level in the resevoir
at the master cylinder, especially when pushing the pistion in.
This sort of activity seemed to be needed about once a year back in the
days that I drove Type 3 VWs here in the land of salt and rust.
