[200q20v] more rear caliper fun

Put a C clamp on it and apply pressure using one of your old (or new) brake
pads. This will distrubute the force evenly. I then use a large pair of
channel locks and turn the piston into the caliper. Once you get it in a
little, tighten the clamp back up, turn the piston, and so on....

This has worked for my rear brake jobs and got the piston back in when it
seemed it wouldn't go. Sometimes I put pressure on the c clamp and let it
sit for five minutes before I turn the piston. Seems necessary when doing a
brake job.
