This vehicle had all new rear brake hardware put on it about 3 years ago, and its got all new front brake hardware on it now, it also has a new master cylinder on it, I have bleed all four wheels several times, but can not get the pedal to pump up and hold good pressure, when driving it, it barely wants to stop even when you smash down the pedal fast. Anyone have any ideas what i can do, is there anything electronic on this vehicle that could be not making the booster function properly or something else? There is no ABS light on or anything either. There are no system leaks on this vehicle that I can tell, fluid is always full.
