Hello Everyone!
Please go easy on me, this is the first time I have had the pleasure of bleeding brake lines. I am working on the '77 Miller Meteor Cadillac which has front disc and rear drums. I replaced the master cylinder (which I bench bled according to the instructions that cam with it), the front hoses, the rear hose, and the steel line that goes to each rear wheel and the line that goes from the portioning valve to the rear hose. I was able to bleed the rear wheel cylinders without issue, but now I am working on the passenger caliper and I am not having luck. When I first started at that corner, I would have my wife pump and hold the brake pedal down; once I cracked the bleeder screw I could see air bubbles coming out of the hose into the glass jar of brake fluid. After doing this 3 times, no more air bubbles were coming out, but no fluid was coming out either. I noticed that when my wife let off of the brake pedal, the caliper did not loosen up. I can use a small pry bar to spread the caliper so the pads are not clamped down to the rotor. I consulted the Chilton's manual, and that had a special note about bleeding cars with front disc brakes that said something about a pin on the master cylinder that has to be held down while bleeding, but I could not find any such pins. Does anyone on the board have any tips or tricks that I could try? Thank you in advance for any suggestions.
