This configuration helps reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The zinc silver coating on the rotor hat offers corrosion resistance, extending the rotor's service life under various driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air flow between the rotor surfaces, which aids in cooling during heavy braking. The rotor’s surface is both drilled and slotted, providing channels for gas and dust to escape, which helps maintain consistent brake pad contact. The directional design ensures the slots and drill patterns are optimized for the rotor’s rotation direction, improving braking response. The rotor has a nominal thickness of 28 mm and a discard thickness of 26 mm, indicating when replacement is necessary to maintain safety and performance. The zinc silver hat finish offers rust resistance, protecting the rotor from corrosion over time. The rotor features five bolt holes with a bolt circle diameter of 114.3 mm, matching the Mazda CX-9’s specifications.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on Mazda CX-9\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust resistant coating\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness for safe braking operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify that the bolt hole pattern matches the Mazda CX-9 specifications (5 bolts, 114.3 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 28 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Proper torque specifications should be followed when securing the rotor to avoid warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM standards for fit and function on Mazda CX-9 vehicles. The rust resistant zinc silver coating enhances durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable braking performance when installed and maintained properly.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51795680231605,"sku":"HBHR-631-80069L","price":117.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63180069L_Fro.jpg?v=1774641813","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-80069l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
