Technical Specifications and Features

This disc brake rotor features a nominal thickness of 27.9 mm (1.098 inches) and a discard thickness of 25.4 mm (1.000 inch), ensuring a long service life before replacement is necessary. The rotor has an outside diameter of 300 mm (11.811 inches) and an overall height of 45.4 mm (1.787 inches). It includes a floating disc mounting system and a straight vane style for efficient cooling. The rotor weighs approximately 8.1 kg (17.81 lbs) and has a coated hat finish to protect against corrosion. It is designed with five stud/lug holes, each 15 mm (0.591 inches) in diameter, and a mounting bolt hole circle diameter of 112 mm (4.409 inches). This rotor does not include ABS tone rings or bearings.

Applications and Problem Solving

• Improves brake cooling to reduce fade during aggressive driving or towing
• Enhances braking consistency by evacuating gases and debris from the rotor surface
• Reduces corrosion on the rotor hat for longer service life
• Addresses uneven rotor wear and vibration issues common in older or stock rotors
• Compatible replacement for worn or damaged rotors on select Mercedes-Benz models

Installation Notes and Tips

• Ensure compatibility with Mercedes-Benz 300SL, 500E, 500SL, SL320, and SL500 before installation
• Inspect brake pads and hardware for wear and replace as necessary during rotor installation
• Follow manufacturer torque specifications for mounting bolts to maintain rotor alignment
• Check rotor thickness before installation to confirm it meets minimum discard thickness
• Proper bedding-in of new rotors and pads is recommended for optimal performance
