This design aids in heat dissipation and helps reduce brake fade under demanding conditions. The zinc black coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for vehicles requiring vented rotors with directional braking surfaces, such as the Ford Ranger and Mazda B2300, B3000, and B4000 models.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis vented disc brake rotor is engineered with a slotted and drilled surface type to enhance heat dissipation and maintain consistent braking performance. The rotor's nominal thickness of 26.1 mm ensures structural integrity, while the discard thickness of 24.5 mm indicates when replacement is necessary to maintain safety. The zinc black finish on the rotor hat offers rust resistance, which is critical for vehicles exposed to varying weather conditions. The rotor features five bolt holes with a 1\/2-20 diameter and a bolt circle diameter of 114.3 mm, matching the factory specifications for compatible Ford and Mazda trucks. The directional brake surface is designed to optimize braking efficiency and reduce noise and vibration during operation.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Ford Ranger and Mazda B2300, B3000, B4000 models\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by overheating during heavy braking\u003c\/li\u003e\n\u003cli\u003eReduces rust and corrosion on rotor hats for longer service life\u003c\/li\u003e\n\u003cli\u003eImproves braking response with slotted and drilled surface design\u003c\/li\u003e\n\u003cli\u003eMaintains structural integrity with vented rotor design for heat management\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 direction. Verify bolt hole alignment with the 114.3 mm bolt circle diameter and use the specified 1\/2-20 bolts. Check rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 26.1 mm and is above the discard thickness of 24.5 mm. Proper cleaning of the rotor surface before installation is recommended to remove any protective coatings or residues.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for fitment and performance on Ford and Mazda trucks. The rust-resistant coating and vented design contribute to durability and consistent braking. While no specific warranty information is provided, the rotor is designed to comply with industry standards for safety and reliability.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51813032853685,"sku":"HBHR-633-54139L","price":138.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63354139L_Fro.jpg?v=1774643061","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-633-54139l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
