The rotor’s three mounting bolt holes and 4.409 inch bolt circle diameter align precisely with the Smart Fortwo’s hub assembly, ensuring straightforward installation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Smart Fortwo vehicles
• Addresses brake pulsation caused by uneven rotor surfaces
• Resolves noise issues related to rotor surface imperfections
• Restores proper rotor thickness for safe braking performance
• Suitable for routine maintenance and brake system overhauls

Installation Notes and Tips

When installing the Raybestos R-Line 980511R rotor, ensure the hub surface is clean and free of rust or debris to promote proper rotor seating. Verify that the mounting bolt holes align correctly with the vehicle’s hub assembly. It is recommended to replace brake pads simultaneously to maintain optimal braking efficiency. Check rotor thickness before installation to confirm it meets the minimum discard thickness of 0.315 inches. Proper torque specifications should be followed for mounting bolts to avoid rotor distortion.
