So your truck you put it in park and it makes a noise as it lunges then if you press the breaks while in park the noise stops Ok now I have had this issue occur with my v6 chevy s10 and my issue that I soon found was the problem was not with the breaks but with my crankshaft positioning sensor I had to order a new one and the problem stopped they are cheap but after a while they will detoriate and get oil build up making them stop working and cause a car to lunge cause it won’t pick up the shafts position
