We need more information. Are the brakes going to the floor, hard brake when pressure build, etc? I too am having an issue after changing booster (2x) and Master Cylinder (2x). Same symptoms of a hard brake aka bad master cylinder.
When I have hard brake, I can fix it by removing the vacuum line for about 3 secs and put back while the engine is on then I have brakes. I do not know what to do at all. It is so annoying that I cannot drive this damn truck just because the ABS system wants to engage on its own.
