Question about Cars & Trucks
Changed the master cylinder, front pads and rotors, and the pedal is really spongy, after changing the master cylinder again thinking i had a faulty master, its still the same... i have gravity bled the brakes, and have power bled them... what would cause it to stay spongy?
Have you driven it since the brakes where replaced?
Did you bleed all four wheels?
have you "broken in" the new pads?
Are the rears drum or disk? If drum are they adjusted correctly?
are you using remanufactured master cylinders? If so keep replacing them. eventually you will get one that works. New is pricey but a better way to go.

it sounds like your still not getting all the air out of your lines. it helps to have a brake bleeder but they are expensive, it also could be that the gasket inside the master cylinder is inverted even if it is a new master cylinder this could be the case, ive had four bad remanned ones in a row, before i got a good one... hope i could help

check under your master cylinder,is there another clyinder below with one line in and one line out,if you do I found this is for the Abs to the rear,I had to replace this it was full of air,and did exactly what yours is now

Did you adjust the rear shoes out? If the rear drum brakes are out of adjustment they will give you a lot of pedal travel. If the pads are worn have no fear of that U-CLIP brake spring, just change one shoe at a time. Take the spring off one side, change the shoe, put the spring back on the post and do the same to the other shoe, no problem.

So long as the brake booster is working, test it by turning on the engine, press the brake pedal all the way down, then shut off engine keeping your foot on the brake pedal, if the pedal comes up slightly pushing against your foot then the booster IS working.
Did you BLEED the brakes??????

I just went to Brake Masters this morning and had them replace the Master Cylinder since I was experiencing the pedal very spongy and going to the floor. When they replaced the Master Cylinder and they gave me back the car, the brakes were still spongy and going to the floor. I addressed this to them and they took another look at it, but when I took it for a second time, the brakes were extremely spongy. It was almost like they gave me back my car in worst condition to when I brought it in. Can you help?
