'\f7 CAUTION:
Yf All brake attaching fasteners are an important attaching part in that they could affect performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one ofthe same
part number
or with and equivalent part if replacement becomes necessary. Do not use replacement parts of
lesser quality or substitute design. Torque values must be used as specified during reassembly to assure
proper retention
of these parts.

GENERAL DESCRIPTION
Pulling up the parking brake lever by hand will set the
parking brake.
Once pulled up, the lever is held by 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 the 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. Refer
to "Parking Brake Adjustment" in
this Section.

5C-2 PARKING BRAKES
OPERATION (Fig. SC-1)
When pulled in the direction "A", the parking lever
presses the secondary shoe against the brake drum
using the lever/shoe joint "8" 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
Primary shoe
Parking cable guide
the secondary shoe through the fulcrum "8". 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. Refer to
"Parking Brake
Adjustment"
in this Section.
