This product line emphasizes precise fitment and consistent braking performance, making it suitable for routine maintenance and repair on vehicles like the Mazda Protege. The rotors feature vented construction to aid in heat dissipation and maintain braking efficiency under normal driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis Centric rotor features a vented design with straight vanes to optimize airflow and reduce heat buildup during braking. The smooth surface finish ensures even pad contact and reduces noise. With a nominal thickness of 0.945 inches (24 mm) and a discard thickness of 0.866 inches (22 mm), the rotor provides a clear service life indicator for replacement. The floating disc mounting style allows for slight movement to accommodate thermal expansion and improve rotor longevity. The rotor’s overall height is 1.843 inches (46.8 mm), and it includes four lug holes sized at 0.512 inches (13 mm) diameter, matching the Mazda Protege’s specifications.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Mazda Protege\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation and vibration issues\u003c\/li\u003e\n\u003cli\u003eRestores braking performance and pedal feel\u003c\/li\u003e\n\u003cli\u003ePrevents overheating and brake fade during normal driving\u003c\/li\u003e\n\u003cli\u003eSuitable for routine brake system maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of rust or debris before installation. Verify the rotor thickness to confirm it is above the discard thickness of 0.866 inches (22 mm). Use proper torque specifications for the lug nuts and mounting bolts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, reuse existing components or replace separately if necessary. It is recommended to replace brake pads simultaneously for optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric C-TEK Standard Disc Brake Rotors are manufactured to meet OEM standards for fit, form, and function.
