Models with drum brakes
The correct adjustment of the handbrake is checked by measuring the stroke in the plungers of the handbrake regulator. The plungers are located on the inside of each rear shield of the drum brake. The total stroke of the two combined plungers should be between 0.5 and 2.0 mm (see Fig. 1.31, 1.32).
If the plunger stroke goes beyond the specified limits, adjustment must be made.
When making adjustments, it is necessary to use a new lock pin.
To adjust the handbrake, first release the handbrake completely, then press the foot brake pedal several times to set the automatic adjusters. Remove the locking pin from the adjuster sleeve, then turn the sleeve to set the total stroke of the plungers within 0.5-2.0 mm. Turn the locking nut manually until it contacts the adjusting sleeve. Hold the lock nut with a wrench, and turn to tighten the adjusting sleeve.
Secure the adjustment by inserting a new lock pin.
Models with disc brakes
Remove the plug from the rear brake mounting plate, at the bottom of the rear of the brake caliper.
With the handbrake released, insert a screwdriver through the plug hole and insert the end of the screwdriver into the teeth of the adjuster wheel. Move the screwdriver up and down to turn the adjuster wheel as needed until the screwdriver engages the teeth.
Unscrew the regulator wheel until it is completely free.
Repeat these procedures on the other brake assembly, then check the operation of the handbrake.
