This product line emphasizes durability and consistent braking performance by using quality materials and precise manufacturing processes. The 120.45077 rotor features a vented design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The coated hat finish provides additional protection against rust and corrosion, extending the rotor's service life. The floating mounting type allows for slight movement between the rotor and hub, which can improve rotor alignment and reduce uneven wear.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor has a nominal thickness of 18 mm and a discard thickness of 16 mm, indicating the minimum thickness before replacement is necessary. The rotor's outside diameter measures 301.7 mm (11.878 inches), suitable for the braking system of the Mazda CX-7. It includes 5 bolt holes arranged on a 114.3 mm bolt circle diameter, matching the vehicle's hub specifications. The center hole diameter is 72 mm, and the rotor height is 56.8 mm. The smooth surface type ensures consistent contact with brake pads, while the vented design improves airflow and cooling. Note that this rotor does not include an ABS tone ring or bearings.\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-7\u003c\/li\u003e\n\u003cli\u003eAddresses brake noise caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eImproves braking performance by restoring proper rotor thickness\u003c\/li\u003e\n\u003cli\u003eReduces brake fade through enhanced heat dissipation\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\u003eEnsure the rotor thickness is measured before installation to confirm it meets the nominal thickness of 18 mm and is above the discard thickness of 16 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Use the correct torque specifications for the 5 mounting bolts on the 114.3 mm bolt circle diameter. Since this rotor uses a floating mounting type, verify proper alignment during installation to avoid uneven wear. This rotor is designed specifically for Mazda CX-7 models, so confirm vehicle compatibility before installation.\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 reliable performance and durability.
