The high carbon content in the gray cast iron improves thermal stability and wear resistance, while the full coating on both the disc and hat surfaces helps prevent rust, extending the rotor's service life under various driving conditions.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThe Pagid 355121972 disc brake rotor is constructed from gray cast iron, a material known for its excellent heat absorption and dissipation properties, essential for maintaining braking efficiency. The rotor features a vented design that allows air to flow between the rotor surfaces, reducing heat buildup during braking. Both the disc and hat are coated to provide a rust-resistant barrier, which is particularly beneficial for vehicles exposed to moisture and road salts. With a full cast construction and six bolt holes, this rotor ensures a secure fit and consistent performance. The dimensions, including a 312 mm outside diameter and 46.20 mm height, are tailored to fit Audi A4, A6, and A8 models, including Quattro versions, ensuring compatibility and proper installation.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Audi A4, A6, and A8 models\u003c\/li\u003e\n\u003cli\u003eAddresses brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eHelps restore braking performance diminished by rotor corrosion\u003c\/li\u003e\n\u003cli\u003ePrevents premature rotor wear due to rust and environmental exposure\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Pagid 355121972 rotor, ensure the hub surface is clean and free of debris to promote proper seating. Torque the six bolts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Verify rotor thickness before installation; discard thickness is 23.00 mm, and the nominal thickness is 25.00 mm. Proper bedding-in of new rotors and pads will help achieve consistent braking response.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003ePagid rotors undergo rigorous quality control to meet OEM standards for fitment and performance.
