4005004 Bushing, Brake Caliper Pin

The 4005004 bushing plays a critical role in the stability and movement of the brake caliper pin within the air disc brake system. Designed to handle heavy-duty grade materials and high-stress environments, this component ensures smooth caliper travel and prevents uneven brake wear. Its precise dimensions are essential for maintaining the structural integrity of the braking assembly under intense thermal and mechanical loads.

This specific part is an OE-equivalent component used in WABCO systems, specifically within MAN TGS and MAN TGX heavy commercial vehicle models. 4005004 is the OE-equivalent bushing used in WABCO MAXX 22 braking systems for MAN TGS and TGX models. Maintaining strict compatibility with these heavy-duty vehicle architectures is vital for ensuring safety and operational efficiency in transport applications.

For workshop technicians, this part requires precise inspection of the caliper pin clearance during installation. Given its role in the air disc brake system, ensuring the diameter specifications of Ø 42 x 38 / 35 mm are met is crucial for preventing caliper binding or uneven pad wear. Regular maintenance of the brake caliper assembly helps prevent premature degradation of the braking components.
