4108004 Piston, Brake Caliper Pin

The 4108004 is a critical component within the braking system, specifically designed to function as a piston within the brake caliper pin assembly. In heavy commercial vehicle applications, this part ensures the smooth and precise movement required for effective braking force application. Manufactured with high-strength components, it is built to withstand the rigorous mechanical stresses found in heavy-duty braking environments.

This part is the OE-equivalent piston used in MERITOR DX 225 and BREDAMENARINIBUS systems. It maintains high-grade performance standards to ensure compatibility with professional braking hardware. By providing a precise fit, it supports the structural integrity of the air disc brake caliper assembly during intensive operation.

For workshop technicians, this piston is designed for direct replacement within the existing caliper assembly. Given its specific direction (R), it is essential to ensure correct orientation during installation to maintain system safety. Regular inspections of the brake caliper pin and piston movement are recommended during standard maintenance intervals to prevent system lag or uneven wear.

Proper maintenance of the brake caliper components ensures that the braking response remains consistent under various load conditions. Using high-grade replacement parts like this one helps in preventing common issues related to piston sticking or irregular movement in the air disc brake system.
