Hi there, I have a nice little 90 crx DX and it's going nuts. I just did new pads, shoes, and rotors (still w/ rear drums). Then it completely lost pressure. Pedal would sink to the floor when the car was running. I just slapped a new Master Cyl and its still doing it... even after 3 complete all around bleeds. I've checked the Booster and it looks fine and tested good. Is there something Im missing? Maybe a recall? Or do I just need to bleed the hell out of it some more? I guess I have to check the rears to make sure they're adjusted just right... but I somehow think that's not it. The e-brake now engages perfectly, when it used to take up to the last few clicks. Anyhow, please! If you know what this little guy is doing, I need to know STAT. This damn thing is my only car and work car... I deliver so I need it by morning. Thanks ahead of time!

 

did you (bench) bleed the master cylinder... didn't see that mentioned

 

Are you losing fluid? Maybe there's a break somewhere in the system? And yeah about the bench bleeding... it would take a while to get all the air out if you didn't do that. Use a vacuum bleeder it's a lot faster.

 

try bleeding your fronts and then your rears completley till nice clean fluid is coming through. if possible use a bleeder that is hooked up to an air compressor ( ), after that it should stop great unless you have a leak in a brake line
