4421010 Repair Kit, Mechanism — WABCO

The 4421010 mechanism repair kit is engineered to restore the precise functionality of air disc brake calipers in heavy commercial vehicle braking systems. This component is essential for maintaining reliable braking force and ensures the mechanical assembly operates within strict safety parameters under heavy-duty load conditions.

This product is the OE-equivalent of the WABCO 13 301 212 mechanism used in DAF, DENNIS, FREIGHTLINER, IVECO, and KÖGEL heavy vehicle braking systems. It is specifically designed to meet the technical requirements of WEDGE BRAKE Ø 360 SIMPLEX configurations, providing a seamless fit for professional workshop applications.

Designed for workshop technicians, this repair kit facilitates efficient maintenance of the caliper mechanism. It is vital for regular service intervals to prevent system degradation. Technicians should ensure all seals and mechanical parts are inspected during installation to maintain optimal braking performance in truck and bus applications.

Proper selection of this kit ensures long-term durability in the braking system. By using high-strength components, the repair process addresses wear within the caliper mechanism, helping to maintain the structural integrity of the entire air brake system.
