of foreign materials; remove any dirty, etc.
• Check the pole piece for damage, and
replace speed sensor if necessary.
• Check speed sensor cable for short or open,
and
replace with a new one if necessary. To
check
for cable short or open, bend or
stretch the cable while checking for
continuity.
• Check the sensor ring for damage including
tooth chipping, and if damaged replace the
axle shaft assembly. Refer to removal of the
sensor ring in
Section 48 "Rear Axle".

'\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.

PARKING BRAKE ROTOR (DRUM)
INSPECTION
Refer to "Rear Disc Brakes" in Section 5A2 for
inspection procedure
of the rotor (drum).
•

PARKING BRAKE ADJUSTMENT
1. Adjustment of parking brake assembly
• Prior to lever stroke adjustment, adjust the rear
brake
shoe/rotor (drum) gap. Perform this
procedure
by loosening the adjust nut of the
equalizer.
a) Remove the adjusting hole plug (rubber) and
turn the shoe adjusting screw
downward with a
small screwdriver so that shoes will expand
until
they get into close touch with the rotor.
(Turn
down the adjusting screw notch by notch
until the rotor does not turn.)
b) Turn the adjusting screw in the opposite
direction (upward) until the rotor can
be turned
lightly. Standard
number of notches to turn
upward: 7 or 8.
Turn the rotor and make sure that there is no
brake dragging.
2. Adjustment of parking brake cable
a) Turn the equalizer nut so that the parking brake
lever travels 6
or 7 notches when pulled up with
a force of 30 kg (66 lb).
b) Make sure there is no brake dragging and
tighten the cable lock nut.
l~l Torque N·m (lb·in) 6 (52)
3. Break-in of parking brake shoe
• When poor braking effect possibly resulting
from insufficient break-in is felt, or just after
replacement
of parking brake shoe, be sure to
conduct break-in by driving vehicle as follows:
a) Forward 50 km/h (30 mph) x 400 m (About 30
seconds) with a lever pull force of 15 kg (33 lb),
and
b) Backward 10 km/h (6 mph) x 50 m (18 sec-
onds)
with a lever pull force of 15 kg (33 lb).
NOTE:
Break-in procedure must be performed under the
safety conditions and traffic rules.
• If braking effect still remains poor after the
above break-in,
wait for some time until
parking brake shoe cools
down and repeat the
procedures
a) and b) noted above.
• On completion of break-in, inspect parking
brake lever stroke, and
if the lever does not
come within the specified number of notches
when pulled up, readjust.
• Excessive brake-in may cause premature wear
of the parking brake lining.
