The spring force that is applied to the tapered brake piston becomes amplified through the wedge
effect. This force becomes further amplified to the power of AB/AC through the mechanical
advantage of a lever and acts on the brake shoe, which in turn, applies a large force to tighten and
lock the piston rod. To disengage the lock, air pressure is supplied through the unlocking port, thus
disengaging the brake spring force.
Brake piston is operated by air pressure.
