About the Element3; Coated Rotor Product Line

The Element3; Coated Rotor line by Raybestos features rotors with a protective coating that helps resist corrosion and extends rotor life. This coating reduces surface rust and maintains a cleaner appearance over time, which is particularly beneficial for vehicles exposed to moisture and road salt. The 980521FZN rotor benefits from this coating, providing enhanced durability and consistent braking performance for Mercedes-Benz models.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Improves braking consistency on Mercedes-Benz C230, C320, CLK350, SLK280, SLK300, SLK350
• Addresses rotor thickness below discard limits to maintain safety
• Reduces brake noise and vibration associated with damaged rotors
• Prevents corrosion-related rotor degradation

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below 1.024 inches discard thickness
• Ensure mounting bolt holes align with the 5-hole, 4.409 inch bolt circle diameter pattern
• Clean hub surface before mounting to prevent runout
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and hardware during rotor replacement for optimal performance
