Was stopped at stop light,with foot on the brake. Started rolling forward and had to press harder on the brake. When holding foot on brake pedal and in gear pedal slowly moves down to the floor. Took vehicle to dealer who was luckily close by. They tested truck brake's and found the same thing. They kept truck, and repaired the next day. Master cylinder was bad. They believe that a seal may have a crack,or a nick in it, allowing pressure to release. The dealer said more than likely gm will ask for part to examine it, so they can't take it apart. Truck had 3173 mile's on it.
