The drilled and slotted surface design helps reduce brake fade by allowing gases and debris to escape, while the directional pattern enhances water dispersion. This rotor line is finished with a rust-resistant zinc silver coating on the hat to extend service life, making it suitable for Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer applications.\u003c\/p\u003e\u003ch2\u003eProduct Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis solid rotor features a nominal thickness of 12.1 mm and a discard thickness of 11 mm, ensuring a clear service limit for safety. The 301 mm outside diameter and 58.2 mm height provide a precise fit for compatible vehicles. The rotor’s 5-bolt pattern with 13.7 mm bolt hole diameter and 114.3 mm bolt circle diameter matches factory specifications for secure mounting. The drilled and slotted surface type is directional, designed to optimize braking efficiency and reduce heat buildup during operation.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake discs on Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer\u003c\/li\u003e\n\u003cli\u003eImproves braking performance by reducing heat and brake fade during heavy use\u003c\/li\u003e\n\u003cli\u003eHelps prevent rust and corrosion with zinc silver coated hat finish\u003c\/li\u003e\n\u003cli\u003eAddresses issues with brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking response in wet or adverse weather conditions due to directional drilled and slotted design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of debris before installation. Verify that the rotor thickness is above the discard thickness of 11 mm to maintain safety standards. Use proper torque specifications for the 5 lug bolts with 13.7 mm diameter to avoid warping. The directional surface requires correct orientation during installation to maximize performance benefits. It is recommended to inspect brake pads and replace if worn when installing new rotors.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for Ford and Mercury vehicles, ensuring compatibility and reliable performance.
