The brake pedal has o-rings inside the valve and will let air pass the o-ring when water or dirt get inside, you can check the leak by: build air, turn off truck, hold brake pedal down(if air gages drop, listen for air coming out the intake) if this is the case, remove the brake pedal and clean the inside.
