ok so i have a 92 hatch with stock brake system. the other day i started to lose pressure in the pedel... now its just gotten worse. ive checked the brake fluid, re bled the brakes and found no leaks... when the car is off the brakes work fine? only when its running. i couldnt find any vaccum hoses that were cracked or not hooked in... anyone got any ideas? brake booster maybe? ive never had this problem before... ps this is not an abs system. and i havent touched the brakes in over 6 months.

 

how did you bleed it? is your eg a si? your supposed to bleed it rear driver,rear passenger,front passenger, front driver. If you bled it right im guessing it should be your brake booster or brake master cylinder.

 

ok nope, wasnt bled right.. but what gets me is everything worked fine for the past 6 months... now this all of a sudden happends... ive never had to deal with a brake booster so i dont know what its like when it fails... the brakes are perfect when the engine is off. just when im drivin its bad.. lol when i need them most!

oh and the car is a hatch vx (power nothing)

 

changed out the brake booster and checked the master cylinder ( no leak detected). bled the brakes according to manual and still no pressure.... i could throw a few wrenches right about now im not gonna lie this fustrates me. any help would be appreciated

 

it's passenger rear first, then driver rear

 

i went with whatever the manual said....
