to which it is connected. It operates automatically and requires
no manual assistance or control lines from other sources.
Periodically, manually drain the reservoir and make sure the
drain passage is not plugged.
Some vehicles are equipped with remote air piloted drain valves.
These are actuated (drained) using dedicated individual controls
from the driver's control panel.

ABS Connections and Sensors

Periodically, push together the ABS wiring connections to ensure
they are fully seated. Press the wheel speed sensors into their
mounting collars to ensure they are fully seated.

Hydraulic Full Power Brakes

Brake Inspection and Adjustment

This inspection or adjustment should only be performed by
qualified service personnel and must be in accordance with
instructions provided in the Service Manual.
Establish a regular schedule for periodic cleaning, lubrication,
and inspection, based on the type of vehicle operation. It is
difficult to predetermine an exact maintenance interval (time or
mileage) since vehicles are used in a variety of applications and
conditions. Refer to the LUBRICATION AND MAINTENANCE
INTERVAL CHART later in this section for recommendations.
On a periodic basis of at least once per year inspect the entire
brake system for:
• The proper operation of the service and parking brakes
164
• The condition of the discs, calipers, and ABS exciter teeth
• Hydraulic fluid leaks
• Hose or pipe damage
• The condition of the ABS wheel speed sensors and wiring
• Proper ABS wheel speed sensor-to-exciter teeth gap
Inspect brake lining at every maintenance interval.
severe service operations or prolonged periods of stop-and-go
operation, the brakes may require more frequent inspection.
Establish inspection intervals that provide for lining replacement
before damage to the disc occurs. Excessive lining wear may
allow the metal brake shoe to damage the brake disc.

Brake Fluid Level

NOTE: If brake fluid is added frequently to maintain the
proper level in the master cylinder, it means that there
is either rapid pad wear or a fluid system leak. A more
frequent and thorough brake inspection is required.
