4421008 Ford Trucks Compatible Mechanism Repair Kit

What does a mechanism repair kit do?

This mechanism repair kit serves as a specialized service set for renewing the internal components of an air disc brake caliper. Instead of replacing the entire caliper housing, this kit allows technicians to restore the internal force-transmission and automatic adjustment assembly, which is essential for maintaining consistent braking performance in heavy commercial vehicles.

Vehicle compatibility

Designed for use in heavy commercial vehicle braking systems, this kit is compatible with Ford Trucks. It focuses on the moving elements that manage pad clearance and force distribution, ensuring the system functions according to original specifications.

Maintenance and installation

When performing maintenance, ensure all internal parts are free of debris and that the assembly is correctly seated to maintain automatic pad clearance. This kit helps extend the service life of the caliper by replacing only the worn moving elements, such as the lever arm or adjuster components, rather than the entire unit.

Service efficiency

Consult your authorized distributor to check the compatibility list.
