1. Remove the plug from the inspection hole.
2.
Use a screwdriver to turn the adjusting wheel 5
until the wheels no longer turn in the forward
direction.
3.
Apply the parking brake a number of times to centre the brake linings.
4. Use the screwdriver to turn the adjusting wheel back (3 to 5 notches) until there is no more
braking resistance to the wheels turning forward.
5. Pull up the parking brake.
6. Check the position of the equaliser 2
on the brake rod 1 .
If the equaliser is perpendicular to the brake rod, the brake clearance is the same on each
wheel.
If the equaliser is not perpendicular, adjust the brakes again.
7.
Pull the parking brake lightly on and compare the braking force on the wheels.
If the braking force on the wheels is not equal, the brakes must be adjusted again.
8. Replace the plug in the inspection hole.
A light rubbing sound when the wheels turn is permissible if it does not affect free turning.
