This product line is designed to provide enhanced braking efficiency and durability, particularly for vehicles like the Ford Explorer Sport and Explorer Sport Trac that demand reliable stopping power under varied driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow better airflow, which helps dissipate heat during braking and reduces the risk of brake fade. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking consistency. The rotor features a rust-resistant zinc silver finish on the hat and a plain finish on the disc, extending the rotor’s service life. With a nominal thickness of 26.2 mm and a discard thickness of 24.5 mm, this rotor meets precise wear limits for safe operation. The 5-bolt hole pattern with a 1\/2-20 diameter and 114.3 mm bolt circle diameter ensures proper fitment on compatible Ford models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors on Ford Explorer Sport and Explorer Sport Trac\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake noise and vibration through vented design\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion with protective zinc silver coating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 24.5 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify the 5-lug bolt pattern and 114.3 mm bolt circle diameter match your vehicle’s specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant coating and vented design contribute to long-term durability.
