These rotors are designed to meet or exceed OEM specifications, providing reliable braking performance with a focus on durability and consistent wear. The 121.62138 rotor exemplifies this line’s commitment to precision engineering, featuring vented construction and a floating disc mounting system to optimize heat management and rotor longevity.\u003c\/p\u003e\u003ch2\u003eTechnical Details and Performance Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design with straight vanes that enhance airflow and heat dissipation, reducing the risk of brake fade during extended use. The rotor’s nominal thickness of 1.181 inches (30.000 mm) ensures a robust braking surface, while the discard thickness of 1.063 inches (27.000 mm) indicates the minimum safe thickness for replacement. The floating disc mounting allows for slight movement to accommodate thermal expansion, improving braking consistency. With a smooth surface type, this rotor is compatible with standard brake pads and does not include an ABS tone ring or bearings.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Cadillac ATS and CT4\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation and vibration issues\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade\u003c\/li\u003e\n\u003cli\u003eRestores braking performance after rotor surface damage\u003c\/li\u003e\n\u003cli\u003eSuitable for vehicles requiring vented rotors with floating mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is measured before installation to confirm it exceeds the discard thickness of 1.063 inches (27.000 mm). Clean the rotor surface and hub mounting area to prevent uneven contact. Use proper torque specifications for the 5 lug nuts with 0.559 inch (14.200 mm) diameter holes. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. The floating disc mounting requires careful alignment during installation to maintain proper rotor movement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric’s C-TEK Standard Disc Brake Rotors are manufactured to meet strict quality standards, ensuring reliable performance and durability.
