Today I replaced the front right caliper on my '70 '02 and was going to bleed it with a new brake bleeder vacuum that I just bought online. I opened the inner bleed screw and before I had a chance to attach the vac to the caliper the fluid began to flow freely. Not just slowly dripping, really flowing. I don't recall ever experiencing this on any car I've owned but I went ahead and let it flow. I did the same on the outer two screws and the fluid flowed from them just as fast. I assume the air purged with the fluid. I drove the car after and the pedal seemed perfect. Could this be an issue with the master cylinder?
