    First adjust the rears up till you have a light drag and then report on what it's then doing.

    Another guy just had the same problem with his 63 fairlane ... He had his calapers on the wrong side ... bleeders were on the bottom .... To see if the boster is bad you can hear it sucking valcume in side the boster ... If the MC is old put a new one on ....

    It would be easier to offer help if you can describe your complete brake system (all the components) and what vehicle they're on.

    Also, what was wrong with the brakes that required you to redo them?

    not to worry



    Are you getting a good flow of fluid out of all 4 bleeders?

    I'm not up on Fords of that year, but Chevy would have what I call "a saftey switch" located at, or in, the brake proportioning valve. That thing has a piston inside that turns the brake warning light "on" in the dashboard if one line pops, etc..but it also shuts off fluid to 2 wheels. So, if you have very little flow at one end of the truck, that could be the problem.
