1990 f250 4x4 brake pedal sinks to floor on its own. bran new every thing all way around. an new master an booster last year. every thing been bled an pedal feels good when truck is off. when i start the truck pedal falls to floor on its own
Hi, my name is XXXXX XXXXX is caused by a defective master cylinder, it will bypass internally and cause the pedal to go to the floor, if the fluid is full and there is no air in the system, it can only be a bad master, i know you said it was replaced last year, but it is still defective, and most parts houses have a one year warranty on these, so they should warrabty the master,Tim
