You must have the necessary replacement friction pads for your machine. Refer to the brake parts
document in your machine manual. You will find part numbers for components or overhaul/repair
kits. The overhaul/repair kit contains O-rings, pads, and other components.
1.
Remove power from the machine (see above notice).
2. Remove the used fluid. See : How to Change Hydraulic Fluid and Remove (Bleed) Air from
the Brake Circuit , page 33 .
3. Remove the two bolts that attach the caliper ( Figure 5 , item 9) and the two caliper halves
( Figure 5 , item 3) to get access to the friction pads. Do not disconnect the hydraulic line ( Fig-
ure 5 , item 6).
4. If there are leaks, see : How to Do a Caliper Overhaul, page 32 before you continue.
5. Replace each friction pad:
a. Remove the brass screw ( Figure 6 , item 3) that attaches the pad to the piston.
b. Attach the new pad to the piston. Tighten the screw.
c. Make sure that the screw head is fully in the recess in the pad.
6. Make sure that the connection o-rings are clean and in their positions ( Figure 6 , item 7).
7. Put the caliper halves in their positions on the brake assembly. Tighten the mounting bolts to
30 foot-pounds (41 Newton-meters).
8. Bleed the brake. See : How to Change Hydraulic Fluid and Remove (Bleed) Air from the
Brake Circuit , page 33 .
9. Supply electrical power to the machine.
