4105003 Brake Caliper Pin Bushing

The 4105003 Brake Caliper Pin Bushing is a critical component within the Air Disc Brake Caliper system, designed to provide stability and smooth movement for the caliper pins. This high-strength component is engineered to withstand the rigorous demands of heavy-duty braking environments, ensuring precise mechanical function and long-term durability during operation.

This part is specifically developed for high-performance applications in heavy commercial vehicles. The 4105003 is compatible with various models from VOLVO (including FH12, FH13, FH16, FM12, FM13, FMX, VNL, and B11R/B13R series), RENAULT TRUCKS (Magnum, Kerax, and Premium), and MACK (Pinnacle and Granite). It also serves as a compatible part for DAF and ALEXANDER DENNIS systems. The 4105003 is the OE equivalent of the specialized bushing used in these heavy-duty braking architectures.

Maintenance technicians should ensure that the dimensions—specifically the Ø 35 - 36 x 39 / 47 mm specifications—match the existing assembly before installation. Regular inspection of the caliper pin area is recommended to prevent wear-related issues in the braking system. Always consult your authorized distributor for exact fitment verification.

Proper replacement of this bushing helps maintain the structural integrity of the air disc brake system, preventing uneven wear on the caliper pins and ensuring consistent braking response.
