okay if anyone has been reading my recent posts than you know that i'm havin brake issues. my pedal is really low and ive replaced the master cylinder and bled the brakes a million times and the pedal is still low. the mechanic told me today that i need a new brake booster and a new ABS pump.. can the ABS pump really make the pedal lower? i'm thinking about just taking the ABS system off.. can anyone tell me if the ABS pump and the brake booster matter in the pedal presssure and how hard it is to take ABS off of it.. btw i have a 92 accord ex coupe

anyone? ... -
The abs could be losing pressure also. I think cpmike has something posted on how to bypass it but to for sure.-1991 Honda Accord LX H22a-

did u check your disc brake..cuz my friend had a smiliar problem..he had good pads and the disc was finish.. he had to press all the way to brake. after he changed his disc it was fixed.My signature works perfectly fine.Comment

yea we checked.. the disks are fine.. the mechanic said its the ABS pump and brake booster.. he adjusted the pedal so itll have a little more pressure but it's still needs a lot more..Comment

i have had this problem for a long time, but i dont have ABS. and the last thing i could think of is the brake boosters. but those puppys are not cheap at all.

You brake booster is what gives you power brakes. It uses vacuum off the engine to assist when the pedal is pressed. The only way to understand what it does is drive down a straight road and turn your engine off then try to brake.-1991 Honda Accord LX H22a-

i believe a way to test the booster is when the car is off, press the brake pedal, it should get REALLY hard. You should only replace the booster when the pedal is really hard to press down when the car is ON, not off. When the car is OFF its supposed to be firm after like 2-3 presses, since it looses vacuum. I would say check your brake lines and sometimes the inner O-ring inside the Master can go bad, causing the pedal to sink. As for the ABS system, its really not worth it to fix that, I think it costs around 2K for an ABS motor, pump and all that crap, its VERY costly to repair.

Pump your brake pedal about 2-3 times like said with the car off and then start it the pedal should shink down=good booster no chang or doesnt pump up bad booster, How are the calipers I assume ABS you have 4 wheel disc??
If you have a claliper slide that is stuck or binding it can act like a master cylinder problem take your calipers off and lube all the slides, If you have rear drums check you wheel cylinders if they are leaking then you are loseing pressure there

besides each disk and the master cylinder is there any where else that there can be a leak? because i highly doubt that if the ABS motor isnt working that shouldnt cause me to lose pressure in the brake pedal.. it should just cause the ABS to not work right?Comment
