Initial problem was no brakes at all, had to stop with emergency brake. Pedal went all the way to floor. First thing I cheked was fluid level. It was basicaly empty, in one side of the reservoir. Put fluid in and pumped brakes. Found obvious leak from LR wheel cylinder. Replaced it and started bleeding. Took forever; there was so much air in there. Wanted to proceed to bleeding front but bleeder fitting on R caliper was broken off, so stopped there.
Results as far as brake performance, other than the leaking wheel cylinder, are the same. Pedal to the floor and not able to brake. Dash brake light stays on, although after pumping a ton of times it would go out. But eventually come back on. It APPEARS that fluid is now holding, as the reservoir stayed full after all the pumping and trying to drive. I am thinking front brakes also have a ton of air in them and need bleeding? Possibly excessive wear of pads and rotors? (havent taken off front wheels yet). Maybe the back still needs bleeding too???
Any advice or insight will be much appreciated, as soon as possible, as I will be back on it in the morning (unfortuneately). This is on a '86 Grand Prix with vaccum brakes. It is not my car and as far as I know probably has not been right for quite sometime. Obviously there were multiple brake problems other than the wheel cyl I replaced today. I was thinking that it should have had some braking power to begin with from the front even with the leaking rear cylinder.
