PREVENTIVE MAINTENANCE
Important: Review the warranty policy before performing
any intrusive maintenance procedures. An extended warranty
may be voided if intrusive maintenance is performed during
this period.
Because no two vehicles operate under identical conditions,
maintenance intervals will vary. Experience is a valuable guide
in determining the best maintenance interval for a vehicle.
GENERAL
Perform the tests and inspections presented at the
prescribed intervals. If the AR-1
described, or leakage is excessive, it should be repaired or
replaced with a new or genuine Bendix remanufactured
unit, available at any authorized parts outlet.
EVERY 3 MONTHS, 25,000 MILES OR 900
OPERATING HOURS
1. Remove any accumulated contaminates and visually
inspect the exterior for excessive corrosion and physical
damage.
2. Inspect all air lines connected to the AR-1

OPERATION & LEAKAGE TESTS
OPERATING TEST
1. Apply and release the brakes several times and check
for prompt application and release at each wheel. If
prompt reaction is noted at some, but not all wheels,
test the AntiLock modulator between the AR-1
and the brake actuator for proper operation. If a "sluggish"
response is noted at all wheels, inspect for a kinked or
obstructed air line leading to or from the AR-1
2. If a complete release of the brakes is noted at some, but
not all wheels, test the antilock modulator between the
AR-1
™
valve and the brake actuator for proper operation.
If an incomplete release is noted at all wheels, inspect
for a kinked or obstructed air line leading to or from the
AR-1
™
valve.
