Power Stop Rear Genuine Geomet High Carbon Coated Rotor Overview

The Power Stop - Rear Genuine Geomet High Carbon Coated Rotor (Part Number EBR686EVC) is engineered for reliable braking performance on select Mercedes-Benz models. Designed with high carbon cast iron and a rust-resistant Geomet coating, this vented disc brake rotor offers durability and consistent stopping power.

• High carbon cast iron material for enhanced heat dissipation
• Rust-resistant Geomet coating to prevent corrosion
• Vented rotor design for improved cooling
• Nominal thickness of 0.87 inches (22.00 mm) with discard thickness at 0.76 inches (19.40 mm)
• Overall height of 2.70 inches (68.30 mm) and outside diameter of 11.80 inches (300.00 mm)
• Mounting bolt hole circle diameter of 4.40 inches (112.00 mm) with 5 lug holes

Detailed Product Description

This disc brake rotor is specifically designed for rear axle applications on Mercedes-Benz vehicles including CLS400, CLS500, CLS550, E250, E350, E400, E500, E550, GLK250, and GLK350 models. The high carbon cast iron construction improves thermal conductivity and reduces the risk of warping under heavy braking conditions. The Geomet coating provides a protective layer that resists rust and corrosion, extending the rotor's service life. Its vented design enhances airflow to dissipate heat more effectively, maintaining braking efficiency during demanding driving scenarios.

The rotor's precise dimensions, including a nominal thickness of 0.87 inches and an outside diameter of 11.80 inches, ensure proper fitment and compatibility with the specified Mercedes-Benz models. The mounting bolt hole circle diameter of 4.40 inches and 5 lug holes align with factory specifications for secure installation.

About the Power Stop - Rear Genuine Geomet High Carbon Coated Rotor Line

The Power Stop - Rear Genuine Geomet High Carbon Coated Rotor product line focuses on delivering rotors that combine high carbon cast iron with a Geomet rust-resistant coating.
