1992 pontiac bonnie.. se break peadel travels all the way to floor as if line or wheel cylinder has poped, they grab when all the way to floor, pedal travels easlely to floor no resistance.. but no fluid leaks full resivour good pads and master was changed 3 yrs back...

Sounds like a bad master cylinder, but I would inspect the entire braking system. In the mean time, DON'T drive the car.:nono:

im a change it out thanks! master and go from there

changed out master that was what it was...
