OPERATION
When pressing on the brake pedal, pressure forces
the brake fluid through the brake line from the
master cylinder to each wheel cylinder. The wheel
cylinder has two pistons, each of which engage a
brake shoe. Fluid pressure pushes the pistons out,
causing the brake shoes to press against the brake
drum.
When the park brake lever is engaged, it pulls on
the cables to the park brake actuator lever, which
engages the two brake shoes. Movement of the
park brake actuator forces the brake shoes to press
against the brake drum.
The friction of the shoes against the drum causes
the drum and wheel to stop turning.
