Detailed Product Overview

This ATE brake rotor is engineered for rear fitments on Mercedes-Benz CL550, CL600, S550, S600, S350, and S400 models across the 2007-2014 range. It is a direct replacement-style rotor for vehicles that require a vented rear disc with the listed dimensions and OE-level specifications. The coated surface helps protect the rotor during storage and early service, while the full cast design supports stable braking under everyday driving conditions.

What This Rotor Helps Address

• Rear brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor wear or surface irregularities
• Corrosion on exposed rotor surfaces
• Reduced braking consistency from rotor thickness loss
• Service replacement needs on Mercedes-Benz rear brake systems

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear axle fitment before installation. Clean the friction surface before service, and inspect pads, caliper hardware, and hub condition at the same time to help prevent uneven wear. For Mercedes-Benz CL550, CL600, and S-Class rear brake service, confirm the vehicle’s brake package and model year against the listed fitment before ordering.
