I have a 78' 350 V8 350 turbo tran Elky and I've been working on it for the past year now and just recently my brakes have been toying around. They go from full power brakes to nothing. I will be driving and I always have to check if they are going to work by pushing down gently. I just bled the brakes again and nothing. Its not just a little pressure there, there's none at all, full vaccum to nothing. Whats worse is the tires spin out when they go kompletly out. I dont know if it has to do with it but I accidently bent the exit line on the back of my quadrajet that links to the power booster. Help please, I would rather fix this my self then take it to get someone else to put effort into it.
