ok here my problem i bypass my 2 wire on my brake booster for my wire tuck...meaning putting the 2 plug together..but my brake light come on??so my problem is when i step on my brake it has alot of pressure on the brake but not loose very hard..so i blead my brake and try it again...and it still did the same thing..when driving u can still stop the car but its very hard on the brake....and would have to really step on the brake for it to stop...post up what you guys think the problem is...

 

did you hook up the one way check valve backwards (the arrow should point towards the vacuum source)? leave the vacuum hose off?

a hard pedal is a sign of either a bad booster or vacuum to the booster

 

you mean that hole that gose into my itm...

 

there is a vacuum line (a black hose) that connects from the brake booster (big black round thing behind the master cylinder) to the little grey plastic piece with an arrow on it (check valve) then from the check valve to the intake manifold.

 

 

lol...i think ur right...ill check when i get home..
