Maintenance:
WARNING
– Danger of injury from crushing.
Maintenance and repair tasks on the brake must be performed only when the machine has been stopped
and has been secured from being turned on again.
Daily
– Keep the brake assembly free of dust and debris buildup during shift operation.
As Needed
– Keep the rotor free of excessive dust and debris buildup. Use a residue-free brake cleaner such
as turpentine, acetone, or
BioBrake
TM
to wipe down the rotor.
Fan Replacement
– Replace fan every three years or 30,000 hours of brake operation.
Brake Pads
– Calipers assemblies are designed to prevent brake pads from extending so far that the backing
plate rubs the rotor. New brake pads measure 15mm [0.591 in] in thickness. Since brake pads will stop
extending with 6mm [0.236 in] of overall thickness left (half of this is a metal backing plate) it is recommended
to replace brake pads prior to wearing the brake pads down to the 6mm [0.236 in] thickness. Note: brake pads
do not contain asbestos.
WARNING
– danger to eyes.
Wear eye protection when working with compressed air.
How to replace the brake pads:
A
For brakes WITHOUT a fan
shroud remove the fan finger
guard. For brakes WITH a fan
shroud remove the fan shroud.
B
Remove (4) bolts to dismount
each caliper mounting half.
C
Brake pads are clipped onto the
piston and are easily removed.
Dismount brake pads by prying
the brake pad away from the
piston until it has become
unclipped. To replace with a new
brake pad simply line up the tabs
of the brake pad with the tabs of
the caliper and press until the
pad has clipped in place.
D
Remount caliper mounting
halves using (4) each previously
removed bolts.
