(Bleed) Air from the Brake Circuit , page 43.
a. Remove power from the machine (see above notice).
b. Remove the bolts (Figure 18 , item 9) that attach the caliper halves (Figure 18 , item 7).
c. Remove the caliper halves.
d. Replace the pads as told in Section : How to Do a Friction Pad Replacement, page 40 if
• the pads make an unusual noise when you apply the brake
• if the rotor is worn or damaged
• if the pad thickness is less than 1/16 inches (2 mm) (Figure 19 , item 14) above the
mounting screw (Figure 19 , item 3). Always replace the two brake pads at the same
time.
e. Put the caliper halves in their positions on the brake assembly. Tighten the mounting bolts
to 30 foot-pounds (41 Newton-meters).
f. Bleed the hydraulic systems as told in Section : How to Change Hydraulic Fluid and Re-
move (Bleed) Air from the Brake Circuit , page 43.
g. Supply electrical power to the machine.
4. Examine the condition of all of the brake system.
a. Make sure that brake mounting components are tightly installed.
b. Make sure that fittings are tight. Make sure that there are no leaks.

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 Section : How to Change Hydraulic Fluid and Remove (Bleed)
Air from the Brake Circuit , page 43.
3. Remove the two bolts that attach the caliper (Figure 18 , item 9) and the two caliper halves
(Figure 18 , item 3) to get access to the friction pads. Do not disconnect the hydraulic line
(Figure 18 , item 6).
4. If there are leaks, see Section : How to Do a Caliper Overhaul, page 42 before you continue.
5. Replace each friction pad:
a. Remove the brass screw (Figure 19 , 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 19 , item 7).
