Brake Pad Repair
NOTE:
The brake pads themselves are maintenance
free. All that is required here is a check for damaged
parts, as well as, inspection to ensure that the brake
disc spins freely.
INSPECT
The thickness of the brake lining must be subjected
to a visual inspection at regular intervals, which de-
pends on vehicle usage, but every 6 months at the lat-
est. In the event of a minimal residual lining thick-
ness, these intervals must be reduced accordingly in
order to avoid major damage to the brake or disk.
• Small brake: Minimum residual thickness 1.0 mm
(0.039 in.) per brake lining plate [6 mm (0.236 in.)
carrier plate thickness]
• Large brake: Minimum residual thickness 2.0 mm
(0.079 in.) per brake lining plate [8 mm (0.315 in.)
carrier plate thickness]
REMOVE
CAUTION
If the pressure hose is too short, it must be dis-
connected in order to allow the brake to be re-
moved. Step 2 and Step 3 must be performed
beforehand. Then release pressure by actuat-
ing hand brake valve.
NOTE:
During this adjusting process, the parking
brake must be released.
1.
Release cap and unscrew. See Figure 6.
2.
Release lock nut and turn setscrew clockwise un-
til it is flush with inside of piston.
3.
Press back ram bolt using a suitable screwdriver
until it comes to rest against piston.
NOTE:
In the event there is insufficient clearance
to remove brake pads, brake must be completely re-
moved. To do this, pull 145 mm (5.708 in.) long bolts
out of brake housing.
4.
Depending on free space available, release one of
two 145 mm (5.708 in.) bolts, remove cotter pin,
unscrew nut, and pull 145 mm (5.708 in.) long
bolt out of brake housing. Remove brake pads.
INSTALL
NOTE:
If magnets do not have sufficient force, they
must also be replaced. Remove by prying out with a
screwdriver.
NOTE:
When brake has been completely removed,
pressure hose must be reconnected to brake housing.
Brake must then be bled.
1.
Replace brake pads and insert 145 mm (5.708 in.)
long bolts into brake housing. Verify magnets
have sufficient force to hold brake pads.
2.
Secure to bracket with 145 mm (5.708 in.) long
bolts, nuts, and cotter pins.
3.
Adjust brakes. See Adjust.

REMOVE
1.
Release lock nut and turn setscrew clockwise un-
til it is flush with inside of piston.
2.
Release pressure by actuating hand brake valve;
then remove pressure hose and completely re-
move brake. The disc springs are now completely
depressurized.
3.
Remove piston stop and remove retaining ring
from housing.
4.
Remove bank of disc springs and piston.
