Checking the brake drum for dirt
1. Unscrew the two cover plates (Fig. 83/1) on
the inside of the brake drum.
2. Remove any dirt and plant debris which
may have entered the drum.
3. Refit the cover plates.
CAUTION
Dirt entering the drums may be
deposited on the brake pads (Fig.
83/2) and thus appreciably reduce
brake performance.
Risk of accident.
If dirt is discovered in the brake drum,
the brake pads must be inspected by
a specialist workshop.
For this to happen, the wheel and
brake drum must be removed.

(Fig. 84).

ground and check the play.
If bearing play can be detected:
Adjust the bearing play
1. Remove the dust cup or hub cap.
2. Remove the split pin from the axle nut.
3. Tighten the wheel nut while turning the
wheel at the same time until the wheel hub
is lightly braked as it turns.

split pin hole. If it is already over a hole, turn
it to the next hole (max. 30°).
5. Fit the split pin and bend it slightly open.

grease and drive it into, or screw it onto the
