4004017 Caliper Cover Bolt Equivalent

What does a brake caliper cover bolt do?

This brake caliper cover bolt serves as a critical fastening component within the air disc brake system. It ensures the secure attachment of caliper covers, protecting internal brake components from external contaminants and maintaining structural integrity during heavy-duty operation.

Technical specifications and fitment

Designed for heavy commercial vehicle braking systems, this component is engineered to withstand high vibrations and thermal cycles common in professional transport environments. The bolt features an M12 x 1.5 thread size and a 50 mm length to ensure precise fitment and secure clamping force.

Installation and maintenance

For professional installation, technicians should verify that the M12 x 1.5 thread specification matches the existing caliper assembly to prevent cross-threading. Regular inspection of these fasteners during brake service is recommended to ensure they remain seated and free from fatigue or corrosion.

System reliability

Maintaining secure caliper covers helps prevent debris from entering the braking mechanism, which is essential for consistent braking performance in heavy commercial vehicles.
