Hi,
I have a gls wagon. After removing the caliper, I tried turning the piston clockwise. After many turns with no results, I turned the piston about a revolution counterclockwise. This, unfortunately, pushed the piston out quite a bit more than where I started at. I then learned about the tool that applies pressure as it turns, so I went to a nearby Auto Zone and rented one. The problem now, is that I don't have enough clearance inside the caliper to position the tool. Any tips or advice? Should the bleeder valve be opened to relieve pressure and allow the piston to travel back into the caliper?
Thanks, Tom
