Technical Description and Specifications

This disc brake rotor features a vented design with curved vanes that enhance airflow and cooling during braking, reducing the risk of brake fade. The rotor’s nominal thickness is 1.260 inches (32.000 mm), with a discard thickness of 1.181 inches (30.000 mm), indicating when replacement is necessary to maintain safe braking. The overall height measures 2.028 inches (51.500 mm), and the outside diameter is 13.150 inches (334.000 mm), matching the original equipment dimensions for the Mercedes-Benz SL500 and SL600. The rotor mounts using a floating disc mounting system with five lug holes, each 0.524 inches (13.300 mm) in diameter, and a mounting bolt hole circle diameter of 4.409 inches (112.000 mm). The center hole diameter is 2.638 inches (67.000 mm). This rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores proper braking performance on Mercedes-Benz SL500 and SL600
• Addresses rotor thickness below discard limits to maintain safety
• Improves heat dissipation to reduce brake fade during extended use
• Suitable for routine brake system maintenance and repairs

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum specifications
• Clean rotor surface and hub mounting area to prevent uneven wear or vibration
• Use proper torque specifications for lug nuts to avoid rotor distortion
