3522017 KNORR-BREMSE SL7/SM7/ST7 22.5" Caliper Carrier

This heavy-duty grade caliper carrier is engineered to provide structural stability within the air disc brake system of heavy commercial vehicles. Designed for high-stress environments, the component ensures the proper alignment and positioning of the brake caliper during intense deceleration cycles, maintaining consistent braking performance.

3522017 is the OE-equivalent of the KNORR-BREMSE K052379K50 caliper carrier used in the KNORR-BREMSE SL7, SM7, and ST7 series. This part is also fully compatible with MERCEDES BENZ systems (OEM: 000 423 10 06), ensuring seamless integration with existing braking hardware for heavy trucks and buses.

Workshop technicians should ensure that the caliper mounting surfaces are free from debris and that all torque specifications are met during installation to prevent vibration or misalignment. This component is specifically designed for 22.5" wheel configurations and should be inspected alongside the brake pads and calipers during routine maintenance intervals to ensure long-term safety and system reliability.
