Okay guys, here's the problem I have been having. This is a 93 Honda Civic EX 2dr too. I replaced my brakes and I have bled them several times but the pedal has barely any pressure. When I turn the car off the pressure builds right back up and the pedal is firm, but when I turn it right back on, it immediately gets soft. I've changed the booster check valve and the master cylinder, but neither have alleviated the problem. Does anyone believe that the brake booster is what is causing the problem?

Thanks for the help.

it could be the booster. however does the car stop normally with the soft pedal?

 

No, braking has definitely diminished.

 

when you were bleeding them was the car running?

 

Sounds like you still have air in the lines, are you following the recommended sequence? (LF RF RR LR) You can also tap the caliper with a hammer or screwdriver handle to get the tiny bubbles out. You shouldn't have to bleed more than once if you do it right.

 

Yes I bled them while the car was running and in that order as well.

 

try bleeding them with the car off. thats how ive done my truck as well as mustang and honda and have never had a problem, also tap the calipers(like said above) that usually helps...and dont try and do it by urself get someone to help you

 

I have always bled the brakes with car switched off and not had any problems so far. Maybe give this a try and let us know how you get on.

 

I replaced the brake booster and that did the trick. Thanks for the suggestions.
