#274366 No. A brake booster will cause a hard pedal. Low pads can cause a spongy feel also. Btw those bleeder machines suck imho. Get a friend and do it the old school way.

#274372 When I did my Integra brake swap, I change out the master, proportioning valve and booster. That is probably your issue.

I agree, sounds like air in the system, I would bleed it old school by hand.

You'll always get air in the lines anytime you open the braking system anywhere. Sometimes it takes awhile to get those stubborn air pockets out of the lines and/or calipers.

#275037 Could be the master cylinder starting to go out. Mine did something similar right before I swapped out all the lines and what not and then it blew out the minute I put it on street replaced it re-bled the brakes and sold as a rock now.


Booster will cause extremely hard pedal, check all your soft lines you might have a kink or a small pin hole. Prop valve is one piece that very rarely goes out. it as well as the booster rarely goes out. Might also have a caliper or a wheel cylinder going bad.


What is your brake setup currently, what kind of car what not?

#275053 94 eg with front n rear integra disc brake conversion... I think I might jus replace the master caz that shit might be the original... Thanks
