Technical Specifications and Features

This vented disc brake rotor features a smooth surface type that supports even pad wear and braking efficiency. The nominal thickness of 1.260 inches (32.000 mm) ensures structural integrity, while the discard thickness of 1.201 inches (30.500 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height is 2.146 inches (54.500 mm), and it has an outside diameter of 12.992 inches (330.000 mm). The floating disc mounting design allows for slight movement to reduce stress and improve braking response. It includes five stud/lug holes with a diameter of 0.669 inches (17.000 mm) and a mounting bolt hole circle diameter of 5.000 inches (127.000 mm). This rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving noise or vibration issues related to rotor surface irregularities
• Upgrading to OEM-spec vented rotors for improved heat dissipation
• Ensuring proper fitment and compatibility with Dodge Durango and Jeep Grand Cherokee brake systems

Installation Notes and Tips

When installing the Centric C-TEK Standard Disc Brake Rotor 121.58006, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify that the rotor thickness meets or exceeds the discard thickness specification. Use proper torque settings on the lug nuts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, confirm these components are in good condition or replaced as needed. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
