Drum Brake System: Description and Operation

DESCRIPTION

The rear brakes use a leading shoe (primary) and trailing shoe (secondary) design.

OPERATION
When the brake pedal is depressed hydraulic pressure pushes the rear brake wheel cylinder pistons outward. The wheel cylinder push rods then push the brake shoes outward against the brake drum. When the brake pedal is released return springs attached to the brake shoes pull the shoes back to their original position.
