ok for like the past month my brakes have been working worse and worse, now my car is undriveable its gotten so bad, this is the problem, when i drive i can push the brake pedal all the way to the floor, there is no pressure built up at all and even once the pedals at the floor i dont stop right away, i pretty much just have to pray to stop in time, i just replaced my brake pads about 2 weeks ago to try and fix this but no progress was made, they didnt help at all, also the brake fluid is not leaking, it is still full, and the ebrake does work, anyone know whats wrong here?

 

My guess would be the master cylinder needs replacing. The sinking pedal is a tell tell sign.

 

Air in the lines maybe>? Have you tried bleeding them? Im not the most knowledgable person here on brakes im sure but do you hear a hissing sound coming from the mastercylinder area? Break booster hose maybe? Just possibilities. I mean, with breaks, It cant really be much. Heh, hope this helps. remember, down shift and ebrake are your best friends.
