Parts List
The parking-brake hand lever is mounted on the transmission tunnel and incorporates the ratchet mechanism and release
button.
The front cable is routed from the hand lever, under the carpet through to an abutment bracket adjacent to the
transmission tunnel, and then connected to the relay lever. The relay lever is attached to a mounting plate by a center bolt
on which it rotates The relay lever mounting plate straddles the transmission tunnel, the plate is secured by four bolts. The
relay lever acts as a center pu ll system to transmit the force from the hand lever to the rear brakes shoes. The equalizer
which is positioned in the center of the rear brake cables balances the force that is applied to the rear brakes.
The rear brake cables are linked together: each cable passes through the rear hub carrier and connects to a brake shoe
expander lever. Application of the parking brake causes the rear cables to pu ll on the expander levers, the expander lever
mechanism rotates on a pivot pin to force the brake shoes outwards to contact the brake drums.
The parking brake cables are adjusted by the rotation of a nu t on the adjuster rod. The parking brake shoes are adjusted by
