BRAKE SYSTEM - CONTINUED
Brake Air Chamber The brake air chamber converts air pressure to mechanical motion. This
movement through the hydraulic master cylinder applies the brakes. When air pressure in the brake
air chamber is released, spring action releases the brakes.
Hydraulic Master Cylinders The hydraulic master cylinders convert the mechanical motion of the
brake air chamber to hydraulic pressure.
Hydraulic Brake Lines The hydraulic brake lines transfer hydraulic pressure from the hydraulic
master cylinder to the wheel cylinders.
Hydraulic Wheel Cylinders The wheel cylinders convert system hydraulic pressure to mechanical
motion and force the brake lining against the brakedrum.
Brakeshoes The two brakeshoes on each wheel assembly are spread apart by the mechanical
movement of the wheel cylinders. The brakeshoes are pushed against the brakedrum, causing
