5D – 6 PARKING BRAKES

GENERAL DESCRIPTION

Pulling up the parking brake lever by hand will set the parking brake. Once pulled up, the lever is held by
means of a ratchet type lock until it is released.  The position of the lever is transmitted through
cable/lever systems to the rear wheels.  These parts are designed to obtain sufficient braking force when
parking on slopes.  When the parking brake is set, or when the ignition SW is in the “ON” position, the
brake warning light illuminates. The rear wheel parking brake is a duo-servo brake (mechanical inside
expansion type) built-in to rear disc brake.  Parking brake adjustment is made through the adjusting hole
(bored through back plate).  Parking brake lever stroke should be adjusted to 6 or 7 notches.

OPERATION

When pulled in the direction “A”, the parking lever presses the secondary shoe against the brake drum
using the lever/shoe joint “B” as a fulcrum and pushes the strut in the direction “C”.  The strut, in turn,
presses the primary shoe against the brake drum.  Counter force “D” to the primary shoe is transmitted
again to the secondary shoe through the fulcrum “B”.  The secondary shoe contacts the drum, thereby
producing braking effect.  Clearance which may result from worn parking brake shoe lining can be
adjusted by turning the adjusting screw
