6.4 ADJUSTMENT OF BRAKES
Significant wear of the brake linings in
-
creases the stroke of the brake cyl-
inder piston and deteriorates braking
performance.
When braking, the piston rod stroke should
be within the specified working range, and
the angle between the piston rod (1) and
the expander arm (3) should be approxi-
mately 90 ° - Figure (6.7) i (6.8). The trailer
wheels must brake simultaneously.
The braking force also decreases when
the angle of operation of the brake cyl-
inder piston rod (5) is not correct - figure
(6.5), (6.6) in relation to the expander arm
(1). To obtain the optimum mechanical
angle of operation of the piston rod fork
(6) must be mounted on the expander arm
(1) so that when fully braked the angle of
ADVICE
The correct stroke of the piston rod should be in the
range of 25 -45 mm.
