Product Line Details: Power Stop - Front Genuine Geomet High Carbon Coated Rotor

This rotor is part of the Power Stop - Front Genuine Geomet High Carbon Coated Rotor line, which focuses on providing rotors with a high carbon cast iron core and a Geomet rust-resistant coating. This combination enhances rotor longevity and performance by reducing corrosion and improving heat management. The vented design further supports thermal regulation, making it suitable for daily driving and moderate performance demands on compatible BMW models.

Technical Description and Specifications

The EBR842EVC rotor is manufactured from high carbon cast iron, a material known for its ability to withstand high temperatures and resist warping under stress. The rotor’s nominal thickness is 0.94 inches (24.00 mm), with a discard thickness of 0.88 inches (22.40 mm), ensuring a clear maintenance threshold for safe operation. Its vented design allows air to flow between the rotor surfaces, improving heat dissipation during braking. The Geomet coating provides a protective layer against rust, extending the rotor’s service life, especially in environments prone to moisture and road salt exposure. The rotor measures 11.80 inches (299.80 mm) in diameter and 2.90 inches (73.80 mm) in overall height, with a mounting bolt hole circle diameter of 120.00 mm and 5 lug holes, matching the specifications required for the listed BMW models.

Compatible Vehicles and Common Applications

• Replacement rotor for BMW 128i front disc brakes
• Suitable for BMW 325i and 325xi front brake systems
• Compatible with BMW 328i and 328xi front brake assemblies
• Addresses issues such as rotor warping, excessive brake noise, and uneven pad wear
• Ideal for restoring braking performance after rotor wear or damage

Installation Notes and Tips

When installing the Power Stop EBR842EVC rotor, ensure the vehicle is securely lifted and the wheel assembly is removed. Clean the hub surface to remove rust or debris before mounting the rotor. Verify the rotor thickness is above the discard limit before installation. Use proper torque specifications for the lug nuts and mounting bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.
