4105009 Compatible Brake Caliper Pin Bushing

What does a brake caliper pin bushing do?

This brake caliper pin bushing plays a critical role in the stability of the air disc brake assembly. By providing a precise interface between the caliper pins and the housing, it prevents excessive movement and vibration during braking cycles. The component is manufactured from high-strength materials to withstand the intense thermal and mechanical stresses encountered in heavy commercial vehicle braking systems.

System compatibility and function

This component is designed for compatibility with air disc brake caliper mechanisms. It ensures that the caliper pins maintain correct alignment, which is essential for even pad wear and reliable deceleration. For technicians, ensuring the correct diameter and fitment is vital for maintaining system integrity.

Installation and maintenance

The technical specifications for this part include a diameter of Ø 35 x 40 / 77 mm. During installation, it is recommended to check all related pins and covers to ensure there is no uneven wear or excessive play in the mechanism. Regular inspection of these bushings helps prevent more costly caliper repairs.

Troubleshooting braking stability

If you experience uneven brake pad wear or unusual vibrations from the braking system, it may be necessary to inspect these bushings. Maintaining high-strength components in the caliper mechanism ensures long-term reliability for fleet managers and workshop technicians alike.
