STAGE 1 Adjusting brakes.

TOOLS 17mm ‘cranked’ ring and open spanner; WD40 light oil

Spray WD40 or similar light oil into the area of the brake adjuster nut on the brake back plate. This will ensure that the adjuster turns freely. 
Adjust the shoes on each brake to the point at which the drum will not turn freely. The adjuster is then used to release the brakes to the point where the drum turns freely, with the brakes just on the point of contact.

STAGE 2 With each of the brakes individually adjusted release the handbrake mechanism temporary restraint. CAUTION The brake system should be completely intact and operational before this stage. With the handbrake down check the ‘free movement’ between the actuator lever and the drawtube in the coupling. The lever should move approximately 2mm before the brake system begins to apply tension. Adjust the fasteners on the main brake transmission rod to achieve the required tolerance. IMPORTANT Over tension in the main brake transmission rod will mean that the road wheel brakes are applied when travelling. This will cause very high brake temperatures and lead to failure of wheel bearings. It may in extremis lead to fire.

STAGE 3 Safety check. Ensure that all lock nuts and safety features are 
fully checked.
