car is a 1992 civic hatch with itr 5 lug

so i got into my car and started to drive and noticed my brake pedal was very very soft.

i e-brake'd it back to my driveway and turned the car off. i bled the system for air.

anytime i pump the pedal when the car is off the pedal gets hard within 2-3 pumps.

but if the car is turned on it just goes soft. any ideas? thanks H-T

 

Leaks? Check the lines, Master/slave for seepage. Air still trapped in system? Re-bleed. Brake systems are not that complicated so you should be able to track the problem down.

 

ive re-bled about 4 times. but im not getting any air bubbles.

how would i check the master cylinder for seepage?

 

Interior of the car. Look under the dash.

 

ok will do when im off work. thanks

 

Check for vac leaks to the booster... I did a rear disc conversion on my eg and afterwards my brakes lasted about 3 weeks... I upgraded to a teggy non abs booster and master cylinder problem solved!!! oh and by the way my symptoms were as you described yours lol

 

if you have a soft pedal and you aren't losing fluid, definitely check your master cylinder and booster

 

Booster! I meant booster and master cylinder (clutch on the brain). You know what I meant.

 

hahaha I picked up what you put down bud

 

lol well thanks guys. much appreciated. ya i was wondering why the slave.lol

 

I am shocked no one asked, but did you install a 1'' MC?

 

That's why you're here.

 

yup once inch master and 40/40 prop valve and coated stainless steel brake lines

 

Start looking for leaks.

Did you bench bleed the MC?
