These rotors are designed to maintain structural integrity under high thermal stress while resisting rust, making them suitable for rear brake applications on performance-oriented vehicles like BMW. The vented design further aids in heat management to reduce brake fade during extended use.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Specifications\u003c\/h2\u003e\u003cp\u003eThe EBR1221EVC rotor is manufactured from high carbon cast iron, which improves thermal conductivity and reduces the risk of warping under heavy braking. The Geomet coating offers a protective layer against rust and corrosion, which is critical for maintaining rotor surface quality over time. This rotor features a vented design, allowing air to flow between the rotor faces to dissipate heat more effectively. With a nominal thickness of 0.94 inches and a discard thickness of 0.88 inches, it provides a clear service life indicator. The rotor’s dimensions, including a 14.60-inch outside diameter and 2.70-inch overall height, are engineered to match the rear brake system requirements of compatible BMW models.\u003c\/p\u003e\u003ch2\u003eCompatible BMW Models and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBMW 550i GT and 550i GT xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 750i and 750i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 750Li and 750Li xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 760Li\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis rotor is specifically designed for rear brake replacement on these BMW models, ensuring proper fitment and brake system performance.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake rotor warping due to heat stress\u003c\/li\u003e\n\u003cli\u003eCorrosion and rust buildup on rotor surfaces\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency from worn or thin rotors\u003c\/li\u003e\n\u003cli\u003eBrake fade during extended or aggressive driving\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear caused by rotor surface irregularities\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Power Stop EBR1221EVC rotor, ensure the rotor surface is clean and free of any protective coatings or contaminants before mounting. Verify that the mounting bolt hole circle diameter of 120 mm and the 5 lug holes align correctly with the vehicle hub. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Always torque mounting bolts to manufacturer specifications and inspect the brake system for any additional wear or damage during installation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003ePower Stop rotors are manufactured to meet or exceed OEM specifications for fit, form, and function.
