check to make sure you dont have a leak in the line, it could be a very tiny leak barley leaking and cause the pressure to not build up.

also did you properly bleed the brakes?

if you pump the brake pedal fast does pressure build up?

pressure builds up alittle bit then it gose back down but if there was a tiny leak wouldnt i lose brake fluid? because my fluid level hasnt went down any and all the parts of the brake system is orginal and i bought new wheel cylinder and new calipers sould i just replace them? then bled the system and see what happens? or could it the master cylinder ?

by the sounds of that you may have air trapped in your system. pressure build up with vehicle off?

try bleeding the system good. if you ahve a metering or combanation valve you have to make sure it is locked in the bypass position so it will actually bleed. and dont pump the pedal fast or too hard.

yes the brakes get hard when the car is off! and what kind of valve are you talking about and where is it because i looked at books and it tells me that i have a valve thats looks like a block that all the brake lines connect to i forgot what kind of valve is and what its called plus when i went to bled the rear passenger brake it was real hard to turn but when i did turn it as much as i could turn it i just saw drips i didnt want to turn it anymore i was afraid i was going to brake it like i said befor everything is original

with pedal hard, engine off hold down about 100-200 pounds of pressure and hold it does pedal stay up or slowly go down?

there is a valve that the brake lines go too after the master cylinder and abs module.

yes the peddle stays up ! and this car dose not have abs

thats quite the thinker! you gonna have to get back to me in a few days, im going to have to do a spot of research for your vehicle!

ok no problem
