3522020 Compatible Brake Caliper Carrier Slide

What does a brake caliper carrier slide do?

The brake caliper carrier slide acts as a vital guide component within the pneumatic disc brake system. By allowing the caliper to slide axially on its carrier, it ensures that braking forces are distributed evenly across the disc surface, maintaining consistent friction and stopping performance under heavy loads.

Compatible vehicles and systems

This specific component is designed for use in Mercedes-Benz vehicles and is compatible with Knorr-Bremse systems. It is engineered to meet the precision requirements of 17.5" wheel configurations, providing reliable guidance for floating-type caliper assemblies in heavy commercial vehicle applications.

Installation and maintenance

For optimal performance, technicians should inspect the slide pins and carrier assembly during routine brake maintenance. Ensuring the slide moves freely without excessive play helps prevent uneven pad wear and ensures the automatic pad clearance adjuster functions correctly within the assembly.

System performance and selection

When replacing worn components, it is essential to verify that all guide pins and bushings are in good condition to maintain system integrity.
