Brakes????

I have a brake problem. When I come to a stop at a light or stop sign there is pressure at the pedal, however it gradually loses pressure and moves all the way to the floor. The brake warning light will come on, I'll pump the brakes and the light will go off and i will have pressure until the next stop. Last week while driving this happened and the light would not come off and the brakes would not regain pressure. I bled the system and now I'm back to only having the pressure problem when I'm at a stop. What should I do? Not sure what needs replaced, if anything. Thanks.

Brett

Assuming you have checked and not found any leaks, it sounds like your master cylinder is out.

Pressure on brake pedal, it sinks to the floor. It's the master cylinder and if you have power brakes, it's leaking into the booster.

Is it advisable to replace both booster and master cylinder or just the master cylinder?

Try just replacing the Master. Be sure to bench-bleed the new master.
