i have an 09 blue bird vision with a brake problem the go to floor no leaks any where at first i was thinking master bad but then i checked for codes and there is a pump motor failure code the brakes dont always go to floor but most of the time they do would a bad pump motor cause pedal fade and i thought the pump motor was only used if the engine stalled
When you say "go to the floor" are you saying the pedal hits the bottom and there is absolutely no braking? Or is there some braking but the pedal travel is excessive? If it's the later I would be thinking there's a problem in the boost system and the bad motor is a symptom. I've never had that kind of problems with my visions.
it stays firm i dont think it an air in system issue but i did activate the abs pump a few times with the laptop then took it for a right and its fine now thats y i am thinkin some how its got to do with the abs pump
