Description

What does a mechanism repair kit do?

This mechanism repair kit serves as a vital component set designed to renew the internal force-transmission and automatic adjustment assembly inside air disc brake calipers on heavy commercial vehicles. By replacing wear-prone elements, this kit restores the caliper's free sliding action and ensures the automatic pad clearance adjustment functions correctly under heavy loads.

Compatible vehicles and engines

The kit is compatible with Ford Trucks, Iveco, Van Hool, and Volvo vehicles. It is also suitable for various heavy commercial applications where precise braking force transmission is required. This allows technicians to renew only the worn internal mechanism instead of replacing the entire caliper unit.

Installation and maintenance

For professional installation, ensure all old seals and bushings are removed thoroughly to prevent debris from entering the new assembly. Maintenance of these components is essential to prevent uneven pad wear or sticking mechanisms. Always verify the fitment against the specific caliper type during service.

Troubleshooting and selection

Regular inspection of the mechanism components can prevent sudden braking performance degradation in heavy-duty fleets.
