The curved vane style enhances airflow between the rotor surfaces, maintaining optimal operating temperatures. With a nominal thickness of 1.260 inches and a discard thickness of 1.181 inches, this rotor meets precise wear limits to ensure safe replacement intervals. The rotor’s outside diameter of 13.583 inches and overall height of 2.008 inches are engineered to exact OEM specifications for proper fitment and performance. The floating disc mounting design allows for slight movement to accommodate thermal expansion and reduce stress on the braking system. This rotor features a smooth surface type, providing consistent pad contact without an ABS tone ring, and includes five lug holes with a 4.409 inch bolt circle diameter for secure installation.\u003c\/p\u003e\u003ch2\u003eAbout the C-TEK Standard Disc Brake Rotors Line\u003c\/h2\u003e\u003cp\u003eThe C-TEK Standard Disc Brake Rotors line by Centric offers rotors manufactured to meet or exceed OEM specifications for fit, form, and function. This product line focuses on providing reliable, direct replacement rotors with standard surface finishes and vented designs to maintain effective braking performance. The 121.35042 rotor exemplifies this approach by combining precise dimensions and vented construction to support consistent braking on Mercedes-Benz ML series vehicles.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors causing brake pulsation\u003c\/li\u003e\n\u003cli\u003eAddressing reduced braking efficiency due to rotor overheating\u003c\/li\u003e\n\u003cli\u003eEliminating noise and vibration from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eRestoring proper rotor thickness to maintain safe braking distances\u003c\/li\u003e\n\u003cli\u003eEnsuring compatibility with Mercedes-Benz ML55 AMG, ML430, and ML500 brake systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify rotor thickness before installation; replace if below discard thickness of 1.181 inches\u003c\/li\u003e\n\u003cli\u003eEnsure proper cleaning of rotor surface to remove any protective coatings\u003c\/li\u003e\n\u003cli\u003eCheck wheel hub and mounting surfaces for debris or corrosion prior to installation\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and replace if worn to ensure optimal rotor performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric manufactures the C-TEK Standard Disc Brake Rotors to meet strict quality standards, ensuring consistent dimensions and material integrity.
