raptor80dad Posted September 3, 2009 Share Posted September 3, 2009 Hello all,I have a 1992 Accord and the brake pedal will go almost to the floor before engaging the brakes. I have replaced the M.C. and bled the system still does the same thing. Pedal will pump up and stay up until I start the motor then the pedal goes right down. Pads and shoes are new also. Any help is appreciated. Quote Link to comment Share on other sites More sharing options...

alex37211 Posted September 4, 2009 Share Posted September 4, 2009 no need for upgrade for a stock car. Are you sure you don't have a leak anywhere? Try and bleed them again. And make sure you're doing it right. Have u bled brakes before? Did you have a friend help? Was he competent? Quote Link to comment Share on other sites More sharing options...

I have bled brakes many times.There are no visible leaks and the master cylinder stays full.Pedal is not spongy it just goes straight down before engaging the brakes,this only happens when engine is running.I have full,solid pedal when car is off. Will try bleeding one more time. Quote Link to comment Share on other sites More sharing options...
raptor80dad Posted September 4, 2009 Author Share Posted September 4, 2009 check your brake lines. maybe upgrade to stainless steel ones Could the old ones be ballooning under booster assisted pressure?I can stand on the pedal all I want when engine is off and it stays solid.

xxhrdcr4lifexx Posted September 4, 2009 Share Posted September 4, 2009 unless your lines are old and weathered prty good and you didnt upgrade you m.c. and booster they shouldnt balloon up... just a thought here kinda retarded but it makes perfect sense if you think about it, but is it possible you didnt tighten your brake lines back up to the m.c and the caliper all the way. ive done that with a master clutch cyl b4 and i was like WTFAX is going on, but it turned out to be it wasnt tightened all the way so it was sucking just enough air to make a whole crap loads difference... it as also possible you purchased a poorly built m.c. Just bkuz its new doesnt mean its going to work, happens more times than you can imagine... if you have no brakes after you checked your lines out, bleed then 1 more time ,but make sure you go rear pass then drive front then rear drive then front pass.. i do believe that is the order it should be done correctly anyways and not like oh ill just do the 1 side 1st then ill do the other just bkuz its easier that way... thats how ppl fck there crap up kuz they dont want to take the time to do it the right way... anywho thats just my 2 cents of an input Quote Link to comment Share on other sites More sharing options...
RichB in AZ Posted September 7, 2009 Share Posted September 7, 2009 Strange, Just for giggles, bleed the brakes again except this time pump about 10 times thru for each brake location. It's a good way to purge the old fluid anyway. Watch the MC to make sure you don't run out. If you get any orange fluid coming out it may be time to strip the calipers and clean them Quote Link to comment Share on other sites More sharing options...
ANDY_CB7 Posted September 8, 2009 Share Posted September 8, 2009 if you've done the m.c you prolly need calipers.... Quote Link to comment Share on other sites More sharing options...
