This design helps to evacuate gases, dust, and water more effectively than plain rotors, contributing to improved brake response and reduced fade. The silver zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life in various driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The rotor's directional surface pattern, featuring both drilled holes and slots, is optimized to maintain clean pad contact and reduce brake fade. With a nominal thickness of 22.1 mm and a discard thickness of 20.6 mm, the rotor provides a balance between durability and performance. The zinc silver finish on the hat offers rust resistance, which is critical for maintaining structural integrity over time. The rotor includes five bolt holes with a 1\/2-20 diameter and a bolt circle diameter of 114.3 mm, matching the specifications required for Ford Explorer and Mazda Navajo models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors on Ford Explorer and Mazda Navajo vehicles\u003c\/li\u003e\n\u003cli\u003eImproves brake cooling to reduce 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\u003eEnhances brake pad bite and reduces noise with slotted and drilled design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is compatible with your specific Ford Explorer or Mazda Navajo model year before installation. Clean the rotor surface to remove any protective coating or residue prior to mounting. Torque the bolts to manufacturer specifications using the 5-bolt pattern with 1\/2-20 diameter holes. Verify the rotor thickness is above the discard thickness of 20.6 mm to ensure safe operation. Proper bedding-in of new rotors and pads is recommended to optimize braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function. The rust-resistant zinc silver finish helps extend rotor life by preventing corrosion. While no specific warranty information is provided, the rotor is designed for durability and consistent performance on compatible Ford Explorer and Mazda Navajo vehicles.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51810608545973,"sku":"HBHR-631-54125L","price":134.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63154125L_Fro.jpg?v=1774642961","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-54125l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
