Pneumatic schematic in the air brakes in any type or build of truck all work in coordination with each other for smooth driving. The brakes would not be able to smoothly stop without them.
In all cars and most trucks HYDRAULIC pressure is used to apply the brakes. In an air brake system such as is found on medium and heavy duty trucks the air is actually released to apply the brakes.

hydralics are used in car brakes,space ships,air planes,heavy equipment,lifts.
you have bleeder valves on all brakes. look for small fittng usually on back side of brakes starting with rear passenger side crack the bleeder valve and have someone slowly pump the brakes wait to see if all air is out tighten when fluid is steady and NO air bubbles. rear pass to rear drive then front pass and then of coursefront drive
