4111004 MERITOR Movement Lever Roller

The 4111004 roller is a critical component within the movement lever assembly of an air disc brake caliper system. Designed to maintain smooth mechanical movement, this part ensures the precise operation of the braking mechanism under heavy-duty conditions. Its robust construction helps maintain the structural integrity of the braking system during frequent actuation.

4111004 is the OE-equivalent movement lever roller used in MERITOR ELSA 225, ELSA 225, DUCO, EX 225, ELSA 195, ELSA 1, and ELSA 2 systems. This component is engineered to meet strict compatibility standards for heavy commercial vehicle brands such as MERITOR and DAF, ensuring seamless integration into existing brake architectures.

For workshop technicians, this part is essential for routine brake caliper maintenance and overhauls. When replacing movement levers or rollers, it is vital to check for smooth rotation and ensure no debris interferes with the mechanism. Regular inspection of these components helps prevent uneven brake wear and maintains optimal braking force in heavy-duty vehicles.

Proper installation of this roller ensures that the movement lever functions within its intended geometric path. This prevents binding or excessive vibration in the air disc brake caliper assembly, contributing to the overall safety and longevity of the vehicle's braking system.
