4120004 Brake Caliper Shaft — MERITOR

The 4120004 Brake Caliper Shaft is a vital component within the air disc brake system, engineered to provide structural stability and precise movement during braking operations. Designed for heavy-duty environments, this part ensures the smooth and reliable function of the caliper assembly under demanding mechanical stresses.

This product is engineered to be compatible with MERITOR systems, specifically supporting models such as ELSA 195, ELSA 225, EX 225, and DX 195/DX 225. It is also suitable for various heavy commercial vehicle applications involving ASTRA, CATERPILLAR, DAF, and IVECO. 4120004 is the OE-equivalent part used in MERITOR ELSA 225 and EX 225 systems.

For workshop technicians, this component requires careful inspection of the mounting surfaces and shaft alignment during assembly to ensure optimal braking response. Regular maintenance of the brake caliper system and checking for wear in the shaft mechanism is essential for maintaining safety standards in heavy commercial vehicle fleets. Proper lubrication and fitment are critical for long-term durability in air disc brake systems.

Maintaining the integrity of the brake caliper shaft is essential for the overall performance of the air disc brake system. This part provides the necessary rigidity to support high-load braking-suspension interactions in trucks and heavy machinery.
