Drum Brake System: Description and Operation

DESCRIPTION






This vehicle's rear wheel drum brakes are a two shoe leading/trailing internal expanding type, with an automatic self-adjuster mechanism. The automatic self-adjuster mechanism used on this vehicle functions differently than the screw type adjusters used in the past. This automatic adjuster mechanism is located directly below the rear wheel cylinder.

OPERATION
This vehicle's rear wheel drum brake shoes expand outward against the brake drum when applied. The automatic self-adjuster is actuated each time the vehicle's service brakes are applied.
