My 85 has really spongy breaks and I just wanted to bounce ideas out and see if what I think is the problem is, is really the problem. The pedal travels about an 1"-1 1/2" before catching hard, I've replaced the master cylinder and the calipers and brake pads so im thinking that its the power booster. I know normally the breaks get harder when the power booster goes out but when I pump the breaks the idle stumbles. This leads me to think that maybe theres a vacuum leak at the seal or something and its not building enough vacuum. Any ideas?
