SYMPTOM/CONDITION:
Some vehicles equipped with Bendix ABS, may exhibit a condition where the brake pedal may not return to its fully released position. As a result, the
rear stop lamps remain illuminated when the brake pedal has been released or the speed control may be inoperative.
DIAGNOSIS:
Verify that the brake pedal return spring is properly installed. Verify that the stop lamp switch is properly adjusted as outlined in the appropriate service
manual. Ensure that the accumulator is fully charged, by pumping the brake pedal (with the ignition key ON) until the pump comes on, then allow it to
fully charge the accumulator. Depress the brake pedal and slowly release it. Verify that the brake pedal does return to the fully released position, by
pulling up on the pedal and verify that the rear stop lamps go out. If the rear stop lamps go out after pulling up on the pedal, proceed with this repair
procedure.
