Detailed Product Description

This Beck Arnley disc brake rotor (part number 083-3804) is designed specifically for Mercedes-Benz A220, CLA250, GLA250, and GLB250 models. The rotor features a vented design that helps reduce heat buildup during braking, which is critical for maintaining braking efficiency and preventing warping. The X drilled surface enhances cooling by allowing better airflow and reducing brake fade under demanding conditions. With a rotor outside diameter of 330 mm and a thickness of 30 mm, this rotor meets the precise specifications required for these vehicles. The 5 lug holes with a 15.2 mm diameter and a bolt hole center-to-center length of 112 mm ensure secure mounting. The rotor’s hub outside diameter of 166 mm and center bore inside diameter of 67 mm provide a proper fit on the wheel hub assembly.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improves braking performance on Mercedes-Benz A220, CLA250, GLA250, and GLB250
• Addresses excessive brake noise due to rotor surface wear
• Helps reduce brake fade during extended or heavy braking
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness meets or exceeds the minimum thickness specification of 28.4 mm to maintain safety standards. Use proper torque specifications for the 5 lug nuts to avoid rotor distortion. This rotor does not include bearings, so reuse existing bearings or replace as necessary. It is recommended to inspect brake pads and other braking components during rotor replacement for optimal system performance.
