The 121.51024 rotor is part of this line, ensuring compatibility and reliable operation for Hyundai Elantra brake systems.

Technical Specifications and Features

This Centric rotor is a solid type, which means it does not have venting channels and is suited for standard braking applications rather than high-performance or heavy-duty use. The smooth surface type helps maintain consistent pad wear and braking efficiency. With a nominal thickness of 0.394 inches and a discard thickness of 0.331 inches, it provides a clear service life indicator to ensure safe replacement intervals. The rotor’s mounting specifications, including a 5-lug hole pattern and a 4.5-inch bolt circle diameter, match Hyundai Elantra factory requirements.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Resolving uneven brake pad wear due to rotor surface imperfections
• Eliminating brake noise caused by damaged or scored rotors
• Restoring proper braking performance on Hyundai Elantra models

Installation Notes and Tips

When installing the Centric C-TEK Standard Disc Brake Rotor 121.51024, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the rotor thickness is above the discard thickness specification of 0.331 inches. Use proper torque specifications for the 5 lug nuts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, confirm compatibility with your vehicle’s existing components. It is recommended to replace brake pads simultaneously for optimal braking performance.
