Its vented design allows air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. With a nominal thickness of 1.34 inches and a discard thickness of 1.26 inches, this rotor meets the specifications required for safe and effective braking. The rotor’s outside diameter of 12.58 inches and five mounting bolt holes with a 4.5 inch bolt circle diameter ensure compatibility with Infiniti FX35, FX37, FX45, and QX70 models. The non-directional brake surface allows for flexible installation without concern for rotor orientation.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInfiniti FX35 (various model years)\u003c\/li\u003e\n\u003cli\u003eInfiniti FX37\u003c\/li\u003e\n\u003cli\u003eInfiniti FX45\u003c\/li\u003e\n\u003cli\u003eInfiniti QX70\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis rotor is designed to replace worn or damaged rotors on these Infiniti models, restoring braking performance and safety.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake rotor warping causing vibration during braking\u003c\/li\u003e\n\u003cli\u003eExcessive rotor wear leading to reduced braking efficiency\u003c\/li\u003e\n\u003cli\u003eOverheating and brake fade during heavy use\u003c\/li\u003e\n\u003cli\u003eUneven rotor surface causing noise or pulsation\u003c\/li\u003e\n\u003cli\u003eCorrosion-related rotor degradation (note: this rotor does not have rust-resistant coating)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the DuraGo BR900420 rotor, ensure the rotor thickness is above the discard thickness of 1.26 inches to maintain safety standards. Clean the hub surface before mounting to prevent runout and ensure proper fitment. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for orientation. Verify that the mounting bolt holes align correctly with the vehicle’s hub assembly. It is recommended to replace brake pads simultaneously to optimize braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures this rotor to meet or exceed OEM specifications for Infiniti FX35, FX37, FX45, and QX70 models. The full cast iron construction and vented design contribute to consistent braking performance and durability. While this rotor does not include a rust-resistant coating, proper maintenance can help extend its service life. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.\u003c\/p\u003e","brand":"DuraGo","offers":[{"title":"Default Title","offer_id":43584834273461,"sku":"GVMP-BR900420","price":72.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/PR_BR900420_Fro.jpg?v=1774634974","url":"https:\/\/www.partcatalog.com\/products\/durago-br900420-disc-brake-rotor","provider":"PartCatalog","version":"1.0","type":"link"}
