Detailed Product Description

This Centric disc brake rotor, part number 228.35138, is specifically engineered for Mercedes-Benz GL350, GL450, GLS450, ML350, and ML400 models. The rotor features a vented design with pillar-style vanes that promote airflow and heat dissipation, helping to maintain consistent braking performance under demanding conditions. The cross-drilled surface reduces heat buildup and assists in water and debris evacuation from the braking surface. With a nominal thickness of 1.260 inches and a discard thickness of 1.157 inches, this rotor meets strict wear specifications to ensure safety and longevity. The floating disc mounting system allows for slight movement to reduce stress and improve rotor alignment. The rotor’s outside diameter measures 13.780 inches, with a center hole diameter of 2.638 inches and a mounting bolt circle diameter of 4.409 inches, accommodating five lug holes sized at 0.594 inches.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improves heat dissipation to reduce brake fade during heavy braking
• Addresses rotor surface corrosion and scoring
• Restores proper rotor thickness for safe braking performance
• Compatible upgrade for Mercedes-Benz GL350, GL450, GLS450, ML350, and ML400 brake systems

Installation Notes and Tips

• Ensure rotor thickness is within discard limits before installation
• Clean mounting surfaces to prevent rotor runout
• Torque lug nuts to manufacturer specifications for proper fitment
• Check for ABS tone ring compatibility; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to optimize rotor performance
