Cleaning the rear calipers from my '73 2.0 I'm restoring and I advanced the pistons while replacing the rubber boots while cleaning everything. Got one piston back in fine, but the one on the side of the parking brake lever won't go back in. Keep turning the set screw and nothing happens- acts like it is stripped- can move the piston with a C-clamp either. What did I screw up??? Rebuilt several calipers and not had this happen before, but the rears on the 914 are a strange duck...

This is a great video on youtube from PMB Performance on the rebuilding of the rear calipers of the 914

It answers all of the little questions as to how these units go together.

Just got done rebuilding mine and they turned out great!

Piston is stuck and probably rusted in caliper. Remove caliper. soak in penetrant. Work and Twist piston until you can remove it . Clean up the bore.
