4161009 Roller, Brake Caliper Mechanism

The heavy-duty roller component is a critical part of the air disc brake caliper assembly, ensuring smooth mechanical movement and precise braking response. Designed to withstand rigorous heavy commercial vehicle operations, this component maintains structural integrity under high-stress braking conditions.

4161009 is the OE-equivalent of the MERITOR SJ4031 roller used in the MERITOR LISA systems. This precision part is also fully compatible with ALEXANDER DENNIS (655377-8, 655377-9), DENNIS (655377-8, 655377-9), NISSAN UD TRUCK (69029760), and VOLVO (8550893) vehicle braking architectures.

For workshop technicians performing brake system maintenance, this component offers a reliable solution for caliper mechanism repairs. It is essential to ensure proper fitment within the brake caliper assembly to maintain optimal braking performance and safety during heavy-duty transport. Regular inspection of caliper rollers is recommended during standard service intervals to prevent system degradation.
