General Information

This section contains information necessary for diagnosis of mechanical conditions which can affect the operation of the BENDIX ANTI-LOCK 10 BRAKE SYSTEM. Specifically, this section should be used to help diagnose mechanical conditions which result in any of the following:

CAUTION: REVIEW THIS ENTIRE SECTION PRIOR TO PERFORMING ANY MECHANICAL WORK ON A VEHICLE EQUIPPED WITH THE BENDIX ANTI-LOCK 10 BRAKE SYSTEM FOR INFORMATION ON PRECAUTIONS PERTAINING TO POTENTIAL COMPONENT DAMAGE, VEHICLE DAMAGE AND PERSONAL INJURY.
(1) ANTI-LOCK warning lamp illuminated

(2) BRAKE warning lamp illuminated

(3) Lack of Power Assist or Excessive Pedal Travel

(4) Brakes Lock on Hard Application

Diagnosis of conditions which are obviously mechanical in nature, such as brake noise, brake pulsation, or vehicle vibration during normal braking, brake pull, and parking brake problems, should be directed to Group 5 Brakes in the service manual.

In order to effectively diagnose an Anti-Lock Brake System (ABS) condition, it is important to read Section 1 of this manual, ANTI-LOCK BRAKE SYSTEM DESCRIPTION, and to follow the diagnostic procedures outlined in this section.

Many conditions that generate customer complaints may be normal operating conditions, but are judged to be a problem due to unfamiliarity with the ABS system. These conditions can be recognized without performing extensive
diagnostic work given adequate understanding of the operating principles and performance characteristics of the ABS system. See Section 1 of this manual to familiarize yourself with the operating principles of the ABS system.
