i posted a thread in the 92-00 civic forum but ill try here. is there any way for the brake booster to put air in the sytem

 

bump bump or could it like over boost and make the pedal go to the floor

 

It may be possible that air leaks past the seal in the master cylinder and then get into your system. It couldn't overboost and make the pedal go the floor. If your pedal is going to the floor you have a leak somewhere.

 

manual has was you can test booster check it out. booster most of time last longer then master cylinders..

 

huh?
