This product line is designed to meet or exceed OEM specifications for fit and function.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 1.098 inches (27.9 mm) and a discard thickness of 1.000 inch (25.4 mm), ensuring a long service life before replacement is necessary. The rotor has an outside diameter of 11.811 inches (300 mm) and an overall height of 2.685 inches (68.2 mm). It includes five mounting bolt holes with a bolt circle diameter of 4.409 inches (112 mm) and a center hole diameter of 3.150 inches (80 mm). The rotor is vented with straight vanes to promote effective heat dissipation and maintain braking efficiency. The smooth surface finish supports consistent pad contact and wear.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz 300SD, 300SEL, and 560SEC models
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion buildup with full coating
• Improves heat management to reduce brake fade during extended use
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor is installed behind the hub as specified. Verify the mounting bolt hole pattern matches the vehicle’s hub assembly. It is recommended to inspect brake pads and replace them if worn when installing new rotors. Clean the rotor surface before installation to remove any protective coatings or residues. Proper torque specifications should be followed for mounting bolts to avoid rotor warping.
