4005005 Brake Caliper Pin Bushing Equivalent

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 caliper mechanism. By maintaining precise alignment for the caliper pins, it prevents excessive vibration and uneven pad wear during heavy-duty braking cycles. High-strength components are utilized to ensure long-term durability in demanding environments.

Compatibility and application

These components are engineered to fit into standard braking assemblies used in the heavy commercial vehicle sector. They provide the necessary clearance and support for the movement of the caliper pins, ensuring that the braking force is applied evenly across the disc surface.

Installation and maintenance

For proper installation, technicians should verify that the bushing diameter matches the original specifications, specifically checking for a Ø 35x39 /20 mm dimension. Regular inspection of these bushings during brake service is essential to prevent caliper seizing or irregular pad wear.

Troubleshooting and service

Maintaining these small but vital parts helps prevent more costly repairs to the entire caliper mechanism. Proper lubrication of the pins within these bushings is recommended during every maintenance interval to ensure smooth operation.
