BRAKES

2002 Ford F-150 • 115,000 miles

The brakes on my F150 stop just fine but sitting with the truck in drive and my foot on the brakes the pedal slowly goes down and the truck creeps forward. I have changed the vacuum assist and master cylinder. Bled the system and checked the calipers/system for leaks. Any idea what the problem may be.

Normally that is a sign of a master cylinder but it may be air in abs unit as it can take up to 3 quarts to properly bleed system. Suggest a power bleeder.
