Do your brakes slowly go to the floor when you press them with engine on, sitting in your driveway?
I don't know if this is normal, or a problem. Pedal is rock hard when power is off, master cylinder passes the bypass test, power booster check valve is fine, all four brakes are working fine, all hoses check out, system does not lose fluid. I've done hard 60-0 stops, and the brakes feel fine, no ABS pulsing, but very good stopping distances. Front pads were just replaced by dealer, not as grabby as the old pads, which is what started me poking around the system. I've bled all four corners, fluid is fine, system has only been opened for brake bleed. ABS shows no codes. The only concern is the pedal going down when sitting in the driveway, I checked my other truck (Excursion), it does it as well.
Any comparison points appreciated.
