Hi, do the brakes still hold the truck as the pedal drops down or does it start to roll or move?

Mostly what you are experiencing is expansion in the system due to the larger volume of fluid because of the ABS and all it's related tubing. We have added about twice the amount of fluid volume and 3 times the hose and tubing wall area so as you add pressure and all that stuff starts to expand (very slightly) the master has to pump out more fluid to fill the area, and the pedal goes down. There is also an accumulator effect in the ABS unit that takes fluid volume also. As long as the pressure is maintained in the system and the brakes don't slip then what you are experiencing is normal.
