5.11
The brake lining thickness should be checked every 6 months.
ADVICE
The minimum thickness of the linings is 5mm.
5.2.7 ADJUSTMENT OF MECHANICAL BRAKES
Significant lining wear increases the stroke of the brake cylinder piston and reduces 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 approximately 90 ° -
compare Figure (5.6). The braking force also decreases when the angle of operation of the
brake cylinder piston rod (5) is not correct - figure (5.5) in relation to the expander arm (1).
To obtain the optimum mechanical angle of operation of the cylinder rod, fork (6) must be
mounted on the expander arm (1) so that when fully braked the angle of operation is approx.
90 °.
ADVICE
The correct stroke of the piston rod should be in the range of 25 - 45mm.
CAUTION
An improperly adjusted brake can cause the rubs to rub against the drum, which can
result in faster wear of the brake linings and / or overheating of the brake.
