Brake adjustment must be done at the brake shoes, slacken all the brake mechanism at the compensator and the coupling. Always start at the brake drum, rotate the brake adjuster
using one of the following methords bepending on the brake setup you have:
Note: Only spin the wheels in a forwards direction during this
operation otherwise the auto reverse mechanism can engage and make accurate
settings impossible.
Method 1
Turn the brake adjuster bolt (usually found on the rear of the brake
backplate) clockwise until some resistance is felt as the brake shoes begin to
grip the drum. Then slowly turn the brake adjuster bolt anticlockwise until the
wheel begins to rotate freely again.
Method 2
Advance the adjuster using a screwdriver through the hole in the rear of the
brake backplate until resistance is felt as the brake shoes begin to grip the
the drum. Then slowly turn the brake adjuster back a few clicks until the wheel
begins to rotate freely again.
Continue the process on all drums and then take up the slack at the compensator and coupling.
Caution! do not overtighten as this will cause the brakes to drag and
overheat. Operate the handbrake several times to ensure that the compensators
and brake shoes are seated. The compensators should remain at 90°
to the brake rod when the brakes are applied. Misalignment can be corrected
through adjustment of the cable locking nuts. Check the travel of the individual
brake cables, this should be between 2 & 5mm, if not re-adjust the brake as
appropriate. Finally check that all the drums still spin freely.
