4306003 Repair Kit, Mechanism — VOLVO

The 4306003 repair kit is an essential component designed for the maintenance and restoration of air disc brake caliper mechanisms. Engineered for high-strength performance, this part ensures the structural integrity and functional precision of the braking system, specifically for the left (L) side orientation. It is designed to meet the rigorous demands of heavy commercial vehicle service environments.

This part serves as the OE-equivalent for several critical systems, including the 653996-25 ALEXANDER DENNIS mechanism used in various heavy-duty transport applications. It is fully compatible with several major manufacturers and systems such as VOLVO (1696924), PACCAR (TP02006095), FORD (9C46 2K16 1BA), IVECO (3346448R1), MAN (1350884, 8605966, N2.50999-0129), and MERITOR (68191510, A164052). It also fits compatible systems from DAF (1694793), RENAULT TRUCKS (50018681F25, 5006018474), and AWD (A4027705).

Workshop technicians should ensure that all assembly surfaces are clean and that the direction (L) matches the vehicle's requirements before installation. Regular inspection of the caliper mechanism is recommended to prevent brake drag or uneven wear. This kit provides a reliable solution for maintaining heavy-duty braking performance and ensuring vehicle safety during routine maintenance cycles.
