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 Section : How to Change Hydraulic Fluid and Remove (Bleed)
Air from the Brake Circuit , page 43 .
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 18: A typical hydraulic brake system, page 38 , item
5). Replace the disk if it is worn or if it is not flat.
3. Examine the brake pads ( Figure 19: The Caliper Components, page 42 , item 4). To do this,
you will remove/replace the calipers and bleed the hydraulic system. See Section : How to Do
