Detailed Product Description

The Centric C-TEK Standard Disc Brake Rotors line is designed to meet or exceed OEM specifications, providing a reliable replacement option for Nissan and INFINITI vehicles. This particular rotor, part number 121.42099, features a vented design with straight vanes that enhance heat dissipation during braking, reducing the risk of brake fade. The rotor’s nominal thickness is 1.181 inches (30.000 mm), with a discard thickness of 1.122 inches (28.500 mm), ensuring a clear service limit for safety and performance. The overall height measures 1.697 inches (43.100 mm), and the outside diameter is 13.780 inches (350.000 mm), matching factory dimensions for proper fitment.

With a floating disc mounting and six lug holes sized at 0.531 inches (13.500 mm) diameter, this rotor is engineered for secure installation on compatible Nissan Armada, QX56, and TITAN models. The smooth surface finish promotes even brake pad wear and consistent stopping power. Note that 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 excessive brake noise from uneven rotor surfaces
• Improving heat management in braking systems prone to fade
• Ensuring proper rotor fitment for Nissan Armada, QX56, and TITAN vehicles

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface to remove any protective coatings or debris prior to mounting
• Use proper torque specifications on lug nuts to avoid rotor warping
• Check compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to maintain optimal braking performance
