I'm attempting my first maintenance on my new-to-me '01 Golf TDI: The rear pads need replacement. Shouldn't be a big deal, I've been doing my own brakes for years. Question is, how do you retract the rear calipers? Some instructions I've seen seem to indicate using a big press-type tool to push the caliper piston back in. Some instructions say the cheapo $5 version of the tool works fine. Still others indicate using a block that sort of plugs in to the caliper piston to twist it back into place.
Help....?
