Rubbers in one or more of the cylinders may be curling or damaged which will not hold any pressure within !
could also be the ABS module

Brake pedal soft after changing pads and bleeding brakes


You will need to bleed the brake system. I would start with the rear brakes lines and work towards the front.You must have key off engine off when bleeding brakes, apply pressure on brake pedal 10 times and hold. The brake line is now ready to be open. Open and let the stream of fluid come out and close the line tight. Then release brake pedal once bleeder screw is close. This procedure must be repeated twice front and back. After, brakes have been bleed pump the brake pedal before putting in drive.
Note: Don't let the resevoir run low on brake fluid. This will cause air bubbles to accumulate on the brake system. Always top off before opening bleeder screw.

Brake pedal has alot of back pressure and car moves in gear.Have to press real hard to stop.How to check abs pump if has one where or brake booster or master cylinder?Don't know how to trouble shoot or...


The air seeping is a dead giveaway. Your power brakes are now manual brakes, but stiffer. The diaphram in the brake booster has torn and the hissing noise is the engine vacuum escaping (you hear it louder when you depress the pedal right?). Replace the booster and you will be fine. The brake lights probably don't work because you can't push the pedal down far enought to release the switch. Please rate. Thanks.

I replaced front and back brakes on my 1996 1500 Chev Suburban. Bled the brakes starting at the farthest line. The pedal is soft and travels too far. Does not seem to stop very good. What is the...


it sounds like there is still air in the brake system that has not been removed.you don`t say if you replaced the brake pads and shoes(in which case you shouldn`t need to bleed)or you replaced a brake line(s) or wheel cylinder or caliper.you will have to keep bleeding the brakes all 4 wheels(trucks don`t use bi-directional braking meaning right rear brakes with left front and so on).bleed both rear brakes then bleed both front brakes,was this problem there before you replaced the brakes(soft pedal noticed) and this is why you changed the brakes or the pedal was soft and the brakes needed changing.its possible that the master cylinder has an internal leak and may need replacing.

If there are no warning lights on, I would try to bleed the brakes to see if the pedal movement is decreased and braking power is increased.

Also, check the power booster vacuum hose and check valve to see if there are any leaks.

After turning off the car, pull the check valve off of the booster, and see if you hear a loud hiss.

You may want to wait a few minutes, first, to test that the booster holds vacuum over time.

Good luck on this repair.

I suggest replacing the master cylinder assuming that you bled the system properly. You sound competent so it seems likely that the seals in the MC might be failing. That being said the brake lines can hold a lot of air :)

Anti lock brakes


Well this is very serious I hope you deal with it right away. You mentioned that sometimes the pedal was hard,do you mean that its all the way up and it doesnt feel like you have power brakes?? If so have you noticed any sounds like air escaping (swoosh sound when brakes applied)? Failure of the power booster causes pedal to become very hard and could possibly be your problem for hard pedal if I understood you correctly. check to make sure that vacuum to the booster is conected properly and hose not kinked..Now for the solution for the pedal fading to the floor... You either have air in your brake system, A bypassing master cylinder , or a hydraulic leak...Were your brakes serviced recently?? if so try bleeding your brake system first...That would be the first step if still the problem persist I would isolate exactly where the problem was coming from.. To do this you would start at the passenger rear wheel and line clamp the brake hose to make that part of your brake sytem inoperable...when clamped try your brakes and note if brakes improved or had know affect on system (when testing obviously im not suggesting you drive to determine results of test procedure)repeat test for each wheel you have isolated the problem when brakes feel normal with one wheel clamped,which ever it may be.. This isnt as hard as it might soun and if you are confused at all dont hesitate to ask questions... Remember the only dumb question is the one you fail to ask I would hate for you to get into an accident ... Good luck!!!
