4001005 Brake Caliper Pin — WABCO Compatible

The technical function of the 4001005 Brake Caliper Pin is to ensure the stable positioning and smooth movement of the caliper assembly within the air disc brake system. This component is manufactured using heavy-duty grade materials to withstand high mechanical stress and environmental exposure in heavy commercial vehicles. Its precise dimensions are critical for maintaining braking stability and preventing system vibrations.

4001005 is the OE-equivalent Brake Caliper Pin used in WABCO PAN 19 DOUBLE and PAN 22 DOUBLE systems, as well as in compatible VOLVO, DAF, FRUEHAUF, RENAULT TRUCKS, and PACCAR braking hardware. This part ensures seamless integration with professional-grade pneumatic braking components to maintain vehicle safety standards.

For workshop technicians, this pin is an essential replacement part during brake system overhauls or caliper maintenance. It is designed to fit specific diameters of Ø 38 / 128 mm to ensure a perfect fit within the assembly. Regular inspection of caliper pins is recommended during scheduled maintenance to prevent uneven wear or caliper sticking. Proper lubrication and fitment checks are vital for maintaining optimal braking performance in heavy-duty trucks and buses.
