Brake pedal all the way to the floor

Asked by Doug Nov 11, 2014 at 03:28 PM about the 1996 Mercury Grand Marquis 4 Dr LS Sedan

Question type: Maintenance & Repair

There was a rumbling feeling in my brake pedal, it suddenly stopped, now I have to
push my brake pedal all the way to the floor. Could this be my brake booster? I've
checked for fluid leaks, brake fluid reservoir is full, no fluid inside the wheels, or
puddles on the ground. Fuses are all good, etc. Please help!!

I'd replace both booster and master cylinder, but you could try just the master first, but the rumbling makes me think booster.
