Parking Brake System: Adjustments

Parking Brake Adjustment

Note: All brakes are self adjusting. Brakes are adjusted by repeated stepping on the brake pedal. (After stepping on the pedal and releasing it, the rear auto-adjuster, in the rear brake, produces a clicking sound. The same operation should be repeated until the sound disappears.)

Take the following steps after overhauling the rear brake assembly.
1. Move the parking brake lever to its fully released position.
2. Parking cable must be loosened sufficiently. (Loosen the adjust nut and the lock nut.).
3. Repeat stepping on the brake pedal firmly, and releasing it until the clicking sound can no longer be heard.
If the difference between the brake drum inside diameter and diameter of the brake shoes is adjusted to be 0.5 mm, the number of times for depressing the brake pedal can be reduced.
4. Remove the drum. Measure the brake drum inside diameter and diameter of the brake shoes.
Shoe clearance: 0.25 mm to 0.40 mm (0.0098 in to 0.0157 inch)
If incorrect, check the brake auto-adjusting system.
5. Rotate the adjust nut of hand brake lever until all slack disappears from the cable. Set the adjust nut.
6. Applying about 30 kg (66 lb.) of force, pull the parking brake lever to its fully set position three or four times.
7. If the parking brake is properly adjusted, the travel between the fully disengaged position and the fully engaged position will be 6 notches.
If the traveling range is not within these limits, repeat steps 1 through 5 again.
After adjusting has been done, check to see if the rear wheel rotates smoothly without drag when turned by hand.
