4306015 Mechanism Repair Kit for Air Brakes

What does a mechanism repair kit do?

This mechanism repair kit is a specialized component set designed to renew the internal force-transmission and automatic adjustment assembly inside air disc brake calipers on heavy commercial vehicles. It functions by multiplying the thrust force from the brake chamber and transferring it to the pads, while simultaneously taking up the clearance that develops as the pads wear down.

Compatible vehicles and systems

The kit is compatible with various heavy commercial vehicles including Renault Trucks, Alexander Dennis, Awd, DAF, Dennis, Iveco, MAN, PACCAR, and Volvo. It is also suitable for systems from Meritor and ZF. This ensures that the worn internal mechanisms can be renewed without the need to replace the entire caliper assembly.

Installation and maintenance

For optimal performance, technicians should inspect the sealing elements and adjustment spindles during every service interval. Proper installation of these components ensures the automatic pad clearance adjuster functions correctly under heavy-duty operating conditions. Always verify the specific fitment requirements for the vehicle's braking system before installation.

Maintenance benefits

Regular maintenance of the caliper mechanism helps prevent uneven pad wear and ensures consistent braking force across all axles.
