This design helps maintain braking efficiency and reduces the risk of brake fade. The zinc silver hat finish provides corrosion resistance, extending rotor life in various driving environments.\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 slotted and drilled surface improves water and debris removal from the braking surface, enhancing wet weather performance. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring safe replacement intervals. The zinc silver coating on the hat area offers rust resistance, preserving structural integrity and appearance. The rotor features 5 bolt holes with a 112 mm bolt circle diameter, matching the Audi S4’s factory specifications.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores braking performance on Audi S4 models with worn or damaged rotors\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during aggressive or repeated braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eEnhances wet weather braking by channeling water away from the rotor surface\u003c\/li\u003e\n\u003cli\u003eProtects against rust and corrosion for longer rotor life\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 20 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the 5-lug, 112 mm bolt circle pattern on the Audi S4. Use proper torque specifications for lug nuts to avoid rotor damage. Directional rotors must be installed following the indicated rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-73024L rotor to meet or exceed OEM standards for fit, form, and function.
