Throw out bearing question

Is there any way to test a pressure plate? I would hate to put it back together to find out the pressure plate was defective. I feel pretty confident the initial problem was the zbar bushing I willl replace the throw out bearing and inspect everything else.

I believe the issue with mine was a partial fracture at the pivot point on one of the fingers that allowed it to distort when pressed, but I'm not sure it was visible without a disassembly and inspection.

Once you "bluprint", rebuild and relubricate your z-bar assembly, you should be ok. I would also use some plyers and carefully close up the gap on the throw out bearing retaining clips, so the hold on to the fork better. Inspect the contact areas of the fork pads and the throw out bearing pads for any deformation, nicks or burrs.
