3505009 Bushing, Brake Caliper Pin

The precision of a braking system relies heavily on the quality of its small components. This bushing is engineered to provide stable support for the brake caliper pin, ensuring smooth movement and preventing caliper seizing during heavy-duty operation. By maintaining structural integrity under thermal stress, it plays a vital role in the overall reliability of the air disc brake system.

3505009 is the OE equivalent of the KNORR-BREMSE and MERCEDES BENZ components used in professional braking systems. This part features a specific diameter of Ø 36 x 40 / 75 mm to ensure exact fitment within the caliper assembly. It is designed for high-performance standards required by workshop technicians and fleet managers.

During routine maintenance or brake system overhauls, technicians should inspect these bushings for wear or deformation. Replacing worn components helps prevent uneven brake wear and ensures that the caliper returns to its neutral position correctly after every application. Proper installation within the caliper pin assembly is essential for maintaining optimal braking performance.

Maintaining the braking system with high-strength components ensures better safety and longevity for heavy commercial vehicles. Always verify compatibility with specific axle or braking hardware to ensure seamless integration.
