I'm working on a friends car and it has this wierd *** brake problem.....brakes are fine at all times...but when you put it in reverse...the pedal hits the floor.

we have bled the the MC, and all four corners...but I suspect a vacuum problem or something...why else would this ONLY happen in reverse???

 

Ummm....that doesnt seem to make any sense at all to me???

 

me either...I had to see it to believe it...I told the guy he was full of *****...but sure enough....only in reverse....thats when I bled his system for him...but same results...the booster must not be getting enough vac in reverse is all I can think of.

 

wow thats a new one

 

yup....

maybe it's just evil?

 

brakes suck, I just wnat my car to run....wtf?

 

its possible
i would say the brake booster vacum hose/line if i had to pick anything
maybe its just possesed.

 

there is vacume when u take the hose off, Im gonnaput ina new brake booster tomorrow, hopefuly thats it, any one have anyother ideas

 

its not becuse of it not getting enought vacume or you wond have that problem all the time does it have rear discs or drums? if drums check the (cant think of the name its late) thing that pushes the shose aganst the drums for leaks

 

I just put on rear disk brakes, this is how the whole ordeal started

 

I don't think it's a vacuum. And air or a leak doesn't seem like it either. All of those would seem consistant if it were the case. I don't know what to say bro. Never heard of that. What kind of car is this? By the way, the thingy that pushes the shoes to the drums is a wheel cylinder.

 

Did you install a disc/disc master cylinder, or are you still using the same master cylinder from your previous disc/drum setup?

-Andie

 

he installed a set up from a 99 civic SI

 

Did you inspect the rear calipers? That's where I'd look first.

 

I haven't taken them apart yet....but they seem fine...

what might we look for in them?

 

Broken seals........leaking fluid (don't think i needed to say that)
Take the pistions out and see if there scared or scratched......(caliper pistons!!!!)
I would check the seals first and if they don't look bad leave it alone until a rebuild kit is purchased.

 

externally they look fine...all seals are in good shape...I haven't pulled em apart yet though

 

I wouldn't if they look fine.....after all they are 99's.........

Where is "Fixhonda's"?? He might have seen this before.

 

TTT

 

improper length on parking brake cables?

incorrect routing of hard lines?

I dunno, stumped me

 

how would the brake cables effect anything? the ebrake works on both sides......anyideas of why the ebrake would **** something up

 

does it have an automatic tranny?

 

Did he swap the master cylinder and proportioning valve also?
Thats an interesting problem, i'm interested in hearing the cause.
