Why do my brakes come and go???

Asked by Mar 12, 2016 at 08:20 AM about the 1999 Ford Explorer 2 Dr Sport 4WD SUV

Question type: Maintenance & Repair

My 99 F explorer sport's brakes will work like
they should for a momentt then next
moment, there gone. Pedal goes to floor.
The fluid in the resivior doesnt go down that
fast at all.There is no physical sign of fluid
leaking anywhere. Ive'already got into an
accident cause the brakes failed backing out
of my driveway. I hit my neighbors garage.
anyway, we have bled the brakes numerous
times now. changed the bleeder screws, put
a new diaphragm thing under the brake
resivoir cap. Oh we also bled the master
cylinder too.   anybody got any suggestions
as to what the problem could be?

Sounds like a bad master cylinder. I would replace it and remember to bench bleed it before installing it.
