Brake failure

Asked by Aug 19, 2018 at 01:49 PM about the 1984 Ford E-350

Question type: Maintenance & Repair

I have a 1984 mobile traveler motor home equipped with a ford 460. The
coach has 34000 miles on it. The problem is the brakes seem to fail in stop
and go heavy traffic. I have replaced master cylinder and bleed brakes also
checked to make sure no brakes were dragging. This seems to happen after
driving for a while and pedal will go to floor and brake light comes on. I pull
over and let sit for 15 minutes and brake pedal comes back with full brakes.
