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

This rotor is part of the Power Stop - Rear Genuine Geomet High Carbon Coated Rotor line, which focuses on providing rotors with a high carbon content and a Geomet coating. The high carbon cast iron material improves thermal conductivity and reduces brake fade, while the Geomet coating offers superior rust resistance compared to standard rotors. This combination ensures longer service life and consistent braking performance, especially for rear brake applications on vehicles like the Mercedes-Benz C36 AMG, C230, and E320.

Detailed Product Description

The Power Stop EBR491EVC rotor is a solid disc brake rotor designed specifically for rear brake systems. Its high carbon cast iron construction allows for better heat management during braking, reducing the risk of warping under heavy use. The Geomet coating provides a protective layer that resists rust and corrosion, which is critical for maintaining rotor integrity over time. With a nominal thickness of 9.90 mm and a discard thickness of 8.30 mm, this rotor meets strict specifications to ensure safe and effective braking. The rotor’s dimensions, including a 290 mm outside diameter and 112 mm bolt circle diameter with 5 lug holes, make it compatible with a range of Mercedes-Benz models such as the CLK350, SLK280, and E430.

Compatible Vehicles and Common Applications

• Mercedes-Benz C36 AMG rear brake replacement
• Rear rotor upgrade for Mercedes-Benz C230 and C240
• Replacement rotor for Mercedes-Benz E320 and E430 rear brakes
• Suitable for CLK320 and SLK350 rear brake systems
• Addresses issues like rotor rust, brake noise, and uneven wear

Installation Notes and Tips

When installing the Power Stop EBR491EVC rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the rotor thickness to confirm it is above the discard thickness of 8.30 mm. Use proper torque specifications for the 5 lug bolts on the 112 mm bolt circle to avoid warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check for any signs of uneven wear or damage on the caliper and hardware during installation.
