Description

What does a mechanism repair kit do?

The caliper mechanism repair kit is a service set that brings together the wearing moving elements of the adjustment and force transmission mechanism inside an air disc brake caliper. This kit is used to renew the internal mechanism rather than the entire caliper housing, providing a cost-effective solution when the caliper shell and slide system remain sound but the internal components have fatigued.

Compatible vehicles and systems

These kits are specifically engineered for heavy commercial vehicles including trucks, tractors, buses, and trailers. They are compatible with Mercedes-Benz, Volvo, DAF, Iveco, Dennis, and Freightliner vehicles. Additionally, these components are suitable for use in vehicles requiring WABCO systems.

Installation and maintenance

For optimal performance, technicians should inspect the piston bushings and seals during installation. Ensuring that all moving parts are free from debris before assembly helps maintain the integrity of the air disc brake system. Regular maintenance of these components is essential for preventing uneven pad wear or brake drag.

Selection guidance

Consult your authorized distributor to ensure you select the correct configuration for your specific braking system requirements.
