The Inspection of the Brake
BNWUUM03.T01 0000277536 A.3 A.7 3/17/20 11:57 AM Released
NOTE:
The brakes shown in this document can look different from your equipment.
NOTE:
Do this inspection when the maintenance schedule tells it is necessary. Do this
inspection after you replace friction pads or do a caliper overhaul.
1. Examine the fluid in the reservoir. Change the hydraulic fluid if it smells, has contamination,
or has an unusual color. See : How to Change Hydraulic Fluid and Remove (Bleed) Air from
the Brake Circuit , page 33 .
NOTE:
Brake fluid can become defective from heat in the brake system. Brake fluid
absorbs water from air. Water in the brake system causes corrosion.
If necessary, add new DOT 3 fluid to 0.25 inch (6.35 millimeters) from the top of the reser-
voir. Follow the precautions on the container.
2. Examine the rotor disk surface ( Figure 5: A typical hydraulic brake system, page 29 , item 5).
Replace the disk if it is worn or if it is not flat.
3. Examine the brake pads ( Figure 6: The Caliper Components, page 32 , item 4). To do this,
you will remove/replace the calipers and bleed the hydraulic system. See : How to Do a Cali-
per Overhaul, page 32 and : How to Change Hydraulic Fluid and Remove (Bleed) Air from
the Brake Circuit , page 33 .
a. Remove power from the machine (see above notice).
b. Remove the bolts ( Figure 5 , item 9) that attach the caliper halves ( Figure 5 , item 7).
c. Remove the caliper halves.
d. Replace the pads as told in : How to Do a Friction Pad Replacement, page 31 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 6 , item 14) above the
mounting screw ( Figure 6 , 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 : How to Change Hydraulic Fluid and Remove
(Bleed) Air from the Brake Circuit , page 33 .
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.
