Maintenance
On vehicles equipped with automatic drain valve(s), moisture
and contaminants are automatically removed from the reservoir
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 ensure 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.

Brake Inspection and Adjustment
This inspection or adjustment should only be performed by
qualified service personnel and must be in accordance with
instructions provided by the
IC Bus ® CE Bus 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 in the Maintenance Interval and Specifications 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.
• 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. During
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.
Fluid Precautions
Use only DOT 3 or DOT 4 Brake Fluid that is properly identified
in a sealed container. Avoid brake fluid contact with painted
surfaces. It will damage the paint.
Brake Lines, Hoses, and Fittings
• Check lines for kinks, dents, corrosion, or ruptures.
• Check hoses for abrasion, kinks, soft spots, ruptures,
collapse, cracks, twists or loose frame supports. When
replacing a hose, be sure there is enough clearance
to prevent the new hose from rubbing against other
components.
• Examine all connections for leaks.
• Repair or replace brake line tubes, hoses or fittings as
required.
