Parking Brake System: Adjustments
PARKING BRAKE ADJUSTMENT1. 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
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) x 400 m (About 30 seconds) with a lever pull force of 15 kg (33 lbs.).
9. Backward 10 km/h (6 mph) x 50 m (About 18 seconds) with a lever pull force of 15 kg (33 lbs.).
NOTE: Break-in procedures must be performed under safe 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 8. and 9. 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 break-in may cause premature wear of the parking brake lining.
