It includes 5 bolt holes arranged on a 114.3 mm bolt circle diameter, compatible with the Mazda CX-9 hub specifications. The hat finish is coated to provide corrosion resistance, and the rotor uses a floating disc mounting design to accommodate thermal expansion and reduce stress.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Mazda CX-9\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eResolves noise issues related to rotor surface imperfections\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency and pedal feel\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion-related rotor degradation\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 meets the nominal thickness of 11.0 mm and is above the discard thickness of 9.0 mm. Clean the rotor surface and hub mounting area to remove rust or debris for proper fitment. Use the correct torque specifications for the 5 mounting bolts on the 114.3 mm bolt circle diameter. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. Proper bedding-in of the new rotor and brake pads is recommended to optimize braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric Premium Disc Brake Rotors are manufactured to meet strict quality standards, ensuring durability and reliable performance.
