WARNING
REAR DRUM BRAKE
Auto-Adjust Brake Mechanism
Theory of Operation
The auto-adjust mechanism is located on the bottom of
the brake assembly. As the brake pad material wears
down, the distance the brake shoes travel to engage the
brake drum becomes longer. When the travel becomes
long enough, the brake lever engages the auto-adjust
lever and causes it to index a tooth on the star wheel
adjuster. This rotates the adjuster, which decreases the
travel needed for the brake shoes to engage the brake
drum.
Note: The auto adjust brakes cannot be manually
adjusted.
Note: The symptom of a low brake pedal may
indicate that the auto adjuster is not working
or the brake cable is not adjusted properly.
Remove the vehicle from service and repair
the brakes.
Note: The brake adjustment is inside of the left
and right brake. Do not adjust the brake by
means of the brake cables as this will cause
malfunction of the brakes. If you hear a
single “clunking” noise while braking it may
be due to incorrect adjustment of the brake
cables or linkage.
Inspecting the Auto-Adjust Brake Mechanism
1: Raise the rear of the vehicle and support with
jack stands.
2: Remove the brake drum.
3: Release the park brake.
4: Back off the auto adjuster star wheel one or two
turns.
5: Reinstall the brake drum and press the bake
pedal.
6: As the brake pedal is pressed, the auto adjuster
should rotate the star wheel. You should hear
a ‘click’ each time the pedal is pressed until the
adjustment is complete. Reconnect the main
positive and negative at the batteries.
7: Remove the blocks from behind the wheels.
8: Test drive the vehicle
