ating levers forward, by means tensioner and cables.
As the actuating lever is pulled forward, the parking
brake strut (which is connected to both shoes), exerts
a linear force against the primary brake shoe. This
action presses the primary shoe into contact with the
drum. Once the primary shoe contacts the drum,
force is exerted through the strut. This force is trans-
ferred through the strut to the secondary brake shoe
causing it to pivot into the drum as well.
A gear type ratcheting mechanism is used to hold
the lever in an applied position. Parking brake
release is accomplished by the hand lever release
button.
A parking brake switch is mounted on the parking
brake lever and is actuated by movement of the
lever. The switch, which is in circuit with the red
warning light in the dash, will illuminate the warn-
ing light whenever the parking brakes are applied.
Parking brake adjustment is controlled by a cable
tensioner mechanism. The cable tensioner, once
adjusted at the factory, should not need further
adjustment under normal circumstances. Adjustment
