Braking system / Handbrake - checking and adjustment


Checking
1 The handbrake is correctly adjusted when the rear wheels are fully locked when the handbrake lever has been pulled up by six to eight notches. This adjustment tolerance will be maintained if the automatic adjuster mechanism is operating correctly to compensate for brake shoe/pad wear.

2 To check the adjustment, proceed as follows.

3 Start the engine and release the handbrake.

4 Depress the brake pedal fully two or three times with the engine running, then stop the engine.

5 Chock the front wheels, then jack up the rear of the vehicle, and support securely on axle stands (see Jacking and Vehicle Support).

6 Apply the handbrake between six to eight notches, and check that both rear wheels are locked. If the wheels do not lock, or if the wheels lock before the handbrake lever has moved through at least six notches, adjust the mechanism as follows.

10 With the mechanism correctly adjusted, tighten the adjuster locknut then, where applicable, refit the rear body undershield, and lower the vehicle to the ground.

11 Check that the handbrake on warning light illuminates with the handbrake lever at the first notch of its travel. If necessary, adjust the switch as described in Chapter 12.

13 Chock the front wheels, and ensure that the handbrake is released.

14 Slacken the locknut on the handbrake adjuster mechanism, then turn the adjuster nut until there is a clearance of approximately 2.0 mm between the end faces of the cable end fittings and the handbrake operating levers on the rear calipers (see illustration).
