The drilled and slotted design helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The rotor’s plain disc finish combined with a zinc silver hat finish provides corrosion resistance, extending the rotor’s service life. With a nominal thickness of 9 mm and a discard thickness of 8 mm, this rotor maintains structural integrity under demanding conditions. The rotor’s 251 mm outside diameter and 35 mm overall height are engineered to match the specifications required for compatible vehicles.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis rotor is compatible with various Ford, Mazda, and Mercury models, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFord Escort\u003c\/li\u003e\n\u003cli\u003eMazda Miata\u003c\/li\u003e\n\u003cli\u003eMazda MX-3\u003c\/li\u003e\n\u003cli\u003eMazda Protege\u003c\/li\u003e\n\u003cli\u003eMercury Tracer\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIt is designed to replace worn or damaged rotors and restore braking efficiency on these vehicles.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade caused by overheating during extended braking\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear due to rotor surface imperfections\u003c\/li\u003e\n\u003cli\u003eCorrosion and rust buildup on rotor surfaces\u003c\/li\u003e\n\u003cli\u003eVibration or pulsation during braking from warped rotors\u003c\/li\u003e\n\u003cli\u003eReduced braking performance from worn or thin rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface and hub are clean and free of debris before installation. Verify that the rotor thickness is within the nominal and discard limits (9 mm nominal, 8 mm discard) to maintain safety and performance. Use the correct torque specifications for the 4 bolt holes (13 mm diameter) and confirm proper alignment with the 100 mm bolt circle diameter. Directional rotors must be installed with the correct rotation direction to ensure optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Product Line Information\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction’s DFC product line, which focuses on delivering rotors with enhanced heat management and corrosion resistance.
