This product line focuses on standard vented rotors with smooth surfaces and integrated ABS tone rings, ensuring compatibility with factory ABS systems and maintaining proper braking function. The 121.84003 rotor exemplifies this line’s commitment to precise fitment and consistent performance.\u003c\/p\u003e\u003ch2\u003eTechnical Details and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design with 40 OEM-style vanes to optimize cooling during braking. The smooth surface finish supports even pad wear and braking response. With a mounting bolt hole circle diameter of 285.5 mm (11.24 inches) and 10 bolt holes sized at 27 mm (1.063 inches), it fits vehicles requiring these exact dimensions. The rotor mounts behind the hub, and the cast-in ABS tone ring ensures proper ABS sensor operation without additional components. The nominal thickness of 36.5 mm and discard thickness of 33.53 mm provide clear service limits for maintenance.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors causing brake pulsation\u003c\/li\u003e\n\u003cli\u003eRestores proper ABS sensor function with integrated tone ring\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade under heavy use\u003c\/li\u003e\n\u003cli\u003eAddresses rotor thickness below manufacturer discard limits\u003c\/li\u003e\n\u003cli\u003eCompatible with vehicles requiring 10-bolt vented rotors with specific diameter and mounting specs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor mounting surface and hub are clean and free of debris before installation. Verify the rotor’s orientation to mount behind the hub as specified. Check the ABS tone ring alignment with the wheel speed sensor to avoid sensor errors. Measure rotor thickness before installation to confirm it meets minimum specifications. Use proper torque settings on mounting bolts to prevent rotor warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric manufactures the C-TEK Standard Disc Brake Rotors to meet or exceed OEM standards.
