The rotor’s surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, improving pad contact and reducing the risk of brake fade during heavy use. The vented design further aids in heat dissipation, maintaining rotor integrity and performance over time.\u003c\/p\u003e\u003cp\u003eThe rotor features a plain disc finish combined with a zinc silver hat finish that includes a rust-resistant coating, extending the rotor’s service life by protecting against corrosion. With a nominal thickness of 25 mm and a discard thickness of 23 mm, this rotor provides a solid balance between durability and performance. The six bolt holes, each 15.7 mm in diameter, fit a 135 mm bolt circle diameter, ensuring proper fitment and secure installation.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors on Ford F-150 and Lincoln Mark LT models\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 through slotted and drilled design\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on braking components\u003c\/li\u003e\n\u003cli\u003eRestores smooth and consistent braking response\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (23 mm) before installation\u003c\/li\u003e\n\u003cli\u003eClean rotor surface and hub mounting area to prevent uneven wear\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eInspect brake pads for wear and replace if necessary during rotor installation\u003c\/li\u003e\n\u003cli\u003eFollow directional rotation indicated by the rotor’s surface pattern\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction’s DFC Brake Rotor - Drilled and Slotted - Silver line is manufactured to meet industry standards for durability and performance.
