Brake pad check
Open the inspection hole (Fig. 55/1) by pulling
out the rubber stopper (if present).
At a residual thickness

the brake pad must be replaced.
Reinsert the rubber tab.
Brake adjustment
Depending on use, the wear and function of the
brakes must be constantly checked and, if nec-
essary, readjustment must be carried out. Read-
justment is required after using approx. 2/3 of the
max. cylinder stroke for emergency braking. To
do this, jack up the axle and secure it against
unintended movement.

Adjusting the linkage adjuster
Move the linkage adjuster by hand in the pres-
sure direction. If the free travel of the long-stroke
diaphragm cylinder pressure rod is max. 35 mm,
the wheel brake must be readjusted.
Adjustments are made using the readjustment
hexagon bolt on the linkage adjuster. Set the free
travel "a" to 10-12 % of the connected brake
lever length "B",
e.g. lever length 150 mm = free travel 15 – 18
mm.

Adjusting the automatic linkage adjuster
Basic settings are made in the same way as for
the standard linkage adjuster. Readjustment
occurs automatically at a cam rotation of approx.
15°.
The ideal lever position (which cannot be altered
owing to the attachment of the cylinder) is ap-
prox. 15° before perpendicularity, and the same
in the actuation direction.
