Brakes

Guest

I have a 73L and my brakes worked adequately but I wanted to improve brake performance. So I purchased new brake pads from Porterfields. During the process of installing them the driver side rear caliper had a stuck bleeder valve that broke off. Tried an e-z-out and it too broke off in the caliper! I then purchased a used caliper from someone.
Installed the rear caliper, installed the new brake pads, added new fluid, and bleed the entire system. After all this the brake peddle just goes to the floor, very little resistance. Yes the reservoir is full of brake fluid. When I press the brake pedal, I here air escaping from around the booster. I can feel air escaping from the bottom area between the booster and the reservoir. Don't know what to do next. Need suggestions on how to fix.

Is there any sign of fluid leaking between the master and the booster?If there is, its time to upgrade to one of the many better masters out there.

You have two separate (probably) problems. First, the pedal going to the floor undoubtably means that for some reason, you still have air in the hydraulic system that wasn't bled out. You did reinstall the spare caliper with the bleeder screws uppermost, right? With bleeder screws pointed downward, it will be all but impossible to eliminate air from the system. The vacuum booster will have no influence on a hydraulic problem.
A non-working vacuum booster simply makes the brakes harder to use but they'll still work. Some air is displaced from the big cylinder as engine vacuum assists the pedal travel each time one steps on the brake pedal.
