5D1–6 PARKING BRAKE SYSTEM (4x4 Model)

Inspection and Repair

Parking Brake Lining Inspection
Check the shoe assemblies for wear by removing the
brake drum.
Replace the shoe assemblies if the lining thickness is less
than 1.0 mm (0.039 in).
Minimum limit: 1.0 m (0.039 in)
Parking Brake Rotor (Drum) Inspection
Refer to"Rear Disc Brakes" in Power-Assisted Brake
System section for inspection procedure of the rotor
(drum).

Parking Brake Adjustment

1. Prior to lever stroke adjustment, adjust rear brake
shoe/rotor (drum) gap. Perform this procedure with
loosening the adjust nut of the hand brake lever.
2. 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.)
3. 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.
4. After the rear brake shoe/rotor (drum) gap has been
adjusted, perform parking brake cable adjustment.
5. Turn the adjusting nut so that the parking brake lever
travels 6–8 notches when pulled up with a force of 30
kg (66 lb).
6. Make sure there is no brake dragging. Then tighten
the cable lock nut
Torque : 13 N·m (113 lb in)
7. 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 as
follows:
8. Forward 50 km/h (30 mph)
seconds) with a lever pull force of 15 kg (33 lb).
9. Backward 10 km/h (6 mph)
seconds) with a lever pull force of 15 kg (33 lb).
NOTE: Break–in procedures must be performed under
safe conditions and traffic rules.
f 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 8. and 9. noted
above.
f 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.
f Excessive break–in may cause premature wear of
the parking brake lining.
