brake issue

[romgolferman]

ok my pedal goes to the floor and it still dont want to stop very well at all. i dont think the backs are working atall. it has new brakes. i blead them many times and it doesnt help. could the master cylinder be bad or something.

Well, if the pedal goes to the floor, then you have a ton of air, or a large leak.


Would help to know what mustang this is....this your 2000gt? Or a fox?

 

[romgolferman]

it is a 91 fox body

With the car off...pump the pedal. Does it firm up?

Do you have any leaks?

 

[romgolferman]

firms up good and no leaks at all. if you pump it while your driving it firms up some but not for long

Based on that, I'd suggest a faulty master cylinder. But I would pull the drums and check the wheel cylinders for leaks first
