Risk of accidents due to uneven braking!
If the brake linings are only replaced on one side of the axle line then the
wheels have an uneven braking force.
Always have the brake linings replaced on both ends of the axle line.
New brake linings do not provide optimal braking and must therefore be run
in by periodic braking.
Risk of damage to the brakes when running them in!
Constant or heavy braking at high speeds can overheat the brakes and
damage them.
The brakes must only be run in through periodic braking.
This must first be done at low speed and then later at medium speed.
•
Perform a test drive to make sure that the new brake pads are sufficiently
run in before putting the truck crane into normal operation.
•
Check the brake lining thickness from the
inside at the openings (1).
If the brake lining thickness has worn down to
the wear marks (stepped edges or grooves) or
if the brake lining thickness has worn down to
only 6 mm (0.25 in):
