This product line emphasizes quality materials and precise manufacturing processes to provide rotors that maintain structural integrity and braking efficiency over time. The 120.45046 rotor benefits from this line’s attention to detail, including a coated hat finish to reduce corrosion and a vented design to enhance heat dissipation during braking.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design, which allows air to flow between the rotor surfaces, reducing heat buildup and minimizing brake fade during extended use. The rotor has a nominal thickness of 18 mm and a discard thickness of 16 mm, indicating when replacement is necessary to maintain safe braking performance. The outside diameter measures 285.7 mm, ensuring compatibility with the specified Mazda models. The rotor includes 5 bolt holes arranged on a 114.3 mm bolt circle diameter, matching the factory mounting pattern. The coated hat finish provides corrosion resistance, extending the rotor’s service life. The smooth surface type ensures even contact with brake pads for consistent braking feel.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Mazda 929 and MPV\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy use\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness for safe braking performance\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion-related rotor damage with coated hat finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Centric Premium Disc Brake Rotor 120.45046, ensure the rotor surface is clean and free of any contaminants before mounting. Verify the bolt hole pattern matches the vehicle’s hub (5 bolts on a 114.3 mm circle). It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Check rotor thickness before installation to confirm it meets the nominal thickness of 18 mm and is above the discard thickness of 16 mm. Proper torque specifications should be followed when securing the rotor to avoid warping.\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 braking performance.
