Jaguar Repair: 1984 XJ6 rear brakes, rear brakes, brake job

Question
Howard,
I was going to re-install my rear calipers tonight, when I thought it prudent to loosen the bleeder screws on the bench. The left caliper bleeder snapped right off. I was using a 7/16" socket for better grip, but it sheared right off. It does not leak, but I cannot bleed that caliper, either. I had heard in the past that air will eventually find its way back to the top, back to the reservoir. Is this correct? I have spent some time pumping the pedal this evening with the hood open, and I do definitely see fluid squirt back in to the reservoir each time the pedal is released, and the rear brakes eventually began to grab. Will this eventually work out, to your knowledge, or experience?
Thanks,
Michael

Answer
It usually depends on the location of an air bubble. In a shop we had to correct the broken bleeder screw before we put the caliper back on.

Bleeder screws are hollow and when they are rusted in they can break off before loosening. I have drilled some out with success and some I had to replace the caliper. We would not take any chances on brakes.

We often had customers that requested only part of a brake job for several reasons but we always refused to do that. Not just because of the shop's liability but how would you feel if you short cut anything on brakes and someone went out and got killed or killed someone else because of a brake problem that you didn't do a 100% correct job on?
