    Lets see if anyone can help me with this problem. No one has been able to help so far....I have a 350.1986 chevy Camaro ..It had front discs back drums..I changed the rear to a 1987 disc setup..I have changed the booster & mastercylinder for disc,disc.I changed the porportional vavle I have a high lift cam so besides the engine vacuum I added a vacuum pump for the booster..when I am on a wet road I cant even lock the wheels up..It feels like manual brakes ,push as hard as u can & still NO brakes.

    do you have a check valve(one way vacum valve)in the hose or in the boosterm if so, check it, make sure its not backwards and that you can only blow thru it one way,and make sure you have strong engine vaume to the booster(which I am sure you do)....let me know,,,,mark aka. CB

    it could also be a bad brake caliper. at the first sign of damage calipers, have it replaced asap because this is what initiates the contact of the brake disc and pads for it to stop, making it the brake actuating part of the vehicle.

    I am also having brake problems. I go to stop and the brakes pull in either direction, sometimes its a really hard pull, other times its not. I have replaced the booster and cylinder due to leaks, calipers because they locked up twice, and hoses (not sure if they were bad before) and that didnt fix the problem. I am thinking that the hoses may have been bad off the shelf, would i be better off using braided line instead of the rubber line? I dont have any unusual wear on the rotors or pads so I doubt that its the calipers.

    I was told that controlled front and rear not left and right so I didnt check that, or bother to replace it.

    you did a great job on that analyzation. yup your right that it is the brakes. but i wonder if you can do that by yourself so i would recommend a source for your Car Repair where you can learn how to fix the brakes. goodluck.
