Detailed Product Description

This Centric C-TEK Standard Disc Brake Rotor 121.35080 is a vented rotor featuring a curved vane style that enhances airflow to reduce heat buildup during braking. The rotor’s floating mounting design allows for slight movement to accommodate thermal expansion, which helps maintain consistent contact with brake pads and reduces the risk of warping. With a nominal thickness of 1.260 inches and a discard thickness of 1.157 inches, this rotor meets the specifications required for safe and effective braking on compatible Mercedes-Benz vehicles.

The rotor measures 12.992 inches in outside diameter and 2.539 inches in overall height, ensuring proper fitment on the specified models. It includes five lug holes with a bolt circle diameter of 4.409 inches, matching the factory mounting points. The smooth surface type is designed for standard brake pad materials, providing reliable stopping power without the need for an ABS tone ring or included bearings.
