Brake pedal goes soft,?

[LePimpOfPimps]

So the otherday I was pulling up to my driveway and I was lightly and gently pressing on the brake pedal and it felt like foam was cushioning it and was just sinking all the way till it hit the wall and my brake signal came on,? But if I press the pedal with good force and speed it's normal xcept for when it's at a stop with little slow force.,?

sounds like air in the system or a bad master cylinder. check for leaks from all 4 calipers and the back of the master. If those are all dry along with the lines I would suspect it being a bad master cylinder. when the internal seals go bad they bleed pressure past them and it sinks to the floor.

It definitely sounds like a bad master cylinder. I had the same exact symptoms. I just had to rebuild my master cylinder and this is what I got. Very quick and easy fix and not to expensive in my opinion.

I tried TE trick where you pump the brakes while engine is off then hold the pedal, turn the car on and if it sinks it's bad., I checked my bleeder and leaked it a bit with a bleeding tool, fluid was all nasty looking like some bacon fat looking color., also noticed some small grains of dirt at the bottom of the bottle when I poured out the fluid., think it was from when I inserted the middle Into the bleeder but idk yet I'm going to bleed the old fluid this week and top off with fresh clear fluid.,

More then sure it's the master or the booster., thanx for the link btw
