    Study Notes

    Monthly Inspection

    • Park the loaded vehicle on flat level ground with wheels pointed straight and ensure parking brake is applied and wheels are chocked.
    • Inspect the gap between the Rubber Axle Stop and spring, which should be between 1/16” and 1/2”. If outside of this range, drive cautiously and re-measure.
    • If the gap is > 1/2”, place the vehicle out of service and contact CMF. If < 1/16” or the Rubber Axle Stop is touching, submit a defect report.

    Brake Pads

    • Bendix ADB22X Disc brake pads must be replaced at 11mm (approximately 7/16”).
