Product Details

ATE, a Continental Automotive Systems brand, applies OE-focused product and process engineering to aftermarket brake parts. The ATE Coated Single Pack Rotor SP10278 reflects that approach with premium materials and a coated surface that helps protect the rotor during storage and early service life. For drivers servicing Mercedes-Benz E250, Mercedes-Benz E320, or Mercedes-Benz E500 rear brake systems, this rotor is built to meet or exceed North American OEM specifications where listed.

The ATE coated rotor line is centered on corrosion protection and consistent manufacturing quality. This rear rotor is a solid design with a non-directional finish, which supports even pad contact during brake service and simplifies rotor preparation before installation. The SP10278 is a direct-fit option for select Mercedes-Benz rear brake applications, including 2014-2016 Mercedes-Benz E250 rear, 2003-2009 Mercedes-Benz E320 rear, and 2003-2006 Mercedes-Benz E500 rear, with note that E500 fitment excludes Sport Package vehicles.

This part cross-references Bosch 36010977 and Brembo 08.9584.11 for the same application.

Common Brake Issues This Rotor Can Address

• Rear brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor wear or surface corrosion
• Reduced braking consistency from rotor thickness loss
• Rust buildup on exposed rotor surfaces
• Service replacement needs on Mercedes-Benz E250, E320, and E500 rear brake systems

Installation Notes and Tips

Verify rotor dimensions and vehicle brake configuration before installation. This rotor is listed for rear use only, and 2003-2006 Mercedes-Benz E500 fitment does not apply to Sport Package models. Clean the hub mounting surface thoroughly, inspect pads and caliper hardware for wear, and confirm the rotor seats flat before road testing. Follow the vehicle manufacturer’s brake service procedures and torque specifications.

Quality Assurance

ATE brake parts are backed by Continental Automotive Systems’ OE brake manufacturing experience and are produced to a higher standard than conventional replacement parts. The coated finish and controlled manufacturing process support dependable fitment and service life for select Mercedes-Benz rear brake applications.
