4456040 Mechanism Repair Kit for Air Disc Brakes

What does a mechanism repair kit do?

The mechanism repair kit plays a vital role in the maintenance of air disc brake caliper assemblies. By replacing worn internal components, it restores the precise movement required for effective braking force application. This kit is engineered with high-strength components to withstand the intense thermal and mechanical stresses found in heavy commercial vehicle braking systems.

Compatible vehicle applications

These kits are designed to support various air disc brake caliper mechanisms used in the heavy commercial vehicle sector. They ensure that the internal movement of the caliper remains fluid and responsive under pressure. For technical service, always verify that the specific kit matches the existing caliper hardware to ensure correct fitment.

Installation and maintenance guidance

Installation should be performed by a workshop technician to ensure all seals and moving parts are correctly seated. Proper maintenance of the mechanism helps prevent uneven pad wear and ensures consistent braking performance across the entire axle. Always inspect the caliper housing for any signs of excessive wear before installing new components.
