SSBC Brakes don't work
I have SSBC brakes on a car that I've never driven. I bought it at an auction. When it was delivered, the brakes were very, very hard. I haven't driven the car any more than 20 feet because I don't trust the brakes. My driveway slopes down quite a bit and I'm afraid I won't be able to stop when I get to the road. I changed the master cylinder and when I had it off, I put it in the vice to see how operable it was. It hung up about 3/4" in when pushing with a screw driver but would continue when I pushed harder. I thought I had the problem solved by replacing the master but after bleeding the system it didn't change very much. The pedal wasn't hard anymore but the braking wasn't there either. I checked the vacuum at the pump and found that it cycles between 12 and 18 inches. It will hold the vacuum for quite a while but as soon as I just touch the brakes, on goes the pump and if I continue to push, the pump continues to run. My guess is that the pump isn't big enough and I'd guess I'd need considerable more vacuum or a reservoir to make the system work. Any suggestions would be appreciated. Can the pump be adjusted? Is there a bigger and better pump available?
