This coating extends rotor life by protecting against rust, which is especially beneficial for vehicles like the Cadillac CTS and STS that require dependable rear brake components. The vented rotor design further supports heat management during braking, maintaining consistent stopping power.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that allows air to flow between the rotor surfaces, reducing heat buildup and minimizing brake fade during extended use. The rotor's nominal thickness is 26.00 mm, with a discard thickness of 24.00 mm, ensuring it meets safety standards for replacement. The Geomet coating provides a protective layer against rust and corrosion, which is critical for maintaining rotor integrity over time. With an outside diameter of 12.60 inches (320 mm) and a mounting bolt hole circle diameter of 115.00 mm, this rotor is specifically designed to fit the rear brake assemblies of Cadillac CTS and STS models. The rotor includes five stud\/lug holes to match factory specifications.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rear rotors on Cadillac CTS and STS\u003c\/li\u003e\n\u003cli\u003ePrevention of rust and corrosion-related rotor damage\u003c\/li\u003e\n\u003cli\u003eImproved heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eRestoration of smooth and consistent rear braking performance\u003c\/li\u003e\n\u003cli\u003eAddressing rotor thickness below manufacturer discard limits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is within the nominal range and above the discard thickness of 24.00 mm. Use proper torque specifications for the 5 lug bolts to secure the rotor. It is recommended to inspect brake pads and other related components during rotor replacement to maintain optimal braking system performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eThe Power Stop - Rear Genuine Geomet Coated Rotor (Part Number AR82119EVC) is manufactured to meet or exceed OEM specifications for Cadillac CTS and STS rear brake rotors.
