i rescently put on new front calipers, front rotors, and braided lines on all four corners. and ever since the brake pedal has been EXTREMELY mushy. i'm now on my third mastercylinder (which did nothing for me) i've tried putting the original calipers back on, and have bleed the brakes a rediculous amout of times. And to add to things to it, the rear brakes aren't fully releasing when you let off of the pedal. i've also made sure that there wasn't any debris in the lines as well. I've also tried moving the adjustment rod that conects to the brake pedal to make sure the piston was getting fully depressed (made no difference) So far nothing has made a bit of change in the feel of the brake pedal. when you bleed the system the pedal only feels slightly mushy but as soon as you try to drive it there are almost no brakes at all (it won't even come close to locking them up) so if anyone one has any advice that would be awesome as i was supposed to autox the car on sunday and thats not looking to good as of now.

thanks in advance for any help

 

Still sounds like a bleeding issue. Any chance that you might not be doing it correctly?

 

ditto

 

i'm pressure bleeding starting on the right rear, left rear, right front, and then left front. and i bench bled the mastercylinder properly. i primed everything when assembling. i've even bled the system at the proportioning valve to make sure i didn't have any bubbles get between there and the mastercylinder

 

is the vacuum hose still hooked up to the booster?

 

i think its rr lf lr rf.... maybe you have a bad hose somewhere

 

i've checked all lines and everything is tight. i've now bled at the calipers, at the mastercylinder, and after the proportioning valve again today with no positive result.....i'm stumped.

 

nevermind guys i got her all fixed......not really sure what i did different but oh well. thanks for the couple of tips though. YAAY i get to autox this weekend
