Detailed Product Description

This disc brake rotor is constructed from high carbon cast iron, which provides improved thermal conductivity and resistance to warping under heavy braking conditions. The full cast, vented design enhances airflow to reduce heat buildup, helping maintain consistent brake performance during extended use. The Geomet coating applied to the rotor surface offers a protective barrier against rust and corrosion, extending the rotor's service life especially in environments prone to moisture exposure.

With a nominal thickness of 0.94 inches (24.00 mm) and a discard thickness of 0.88 inches (22.40 mm), this rotor meets strict OEM specifications for thickness tolerances. The 13.60-inch (344.90 mm) outside diameter and 120 mm mounting bolt circle diameter with 5 lug holes ensure compatibility with the rear brake assemblies of various BMW models.

Compatible BMW Models and Applications

This Power Stop rotor is compatible with a range of BMW vehicles, including the 535i GT, 535i GT xDrive, 550i, 550i xDrive, 640i, 640i Gran Coupe, 640i xDrive, 640i xDrive Gran Coupe, 650i, 650i Gran Coupe, 650i xDrive, 650i xDrive Gran Coupe, 740i, 740Ld xDrive, 740Li, 740Li xDrive, and ActiveHybrid 7.

Power Stop - Rear Genuine Geomet High Carbon Coated Rotor Product Line

The Power Stop - Rear Genuine Geomet High Carbon Coated Rotor line focuses on delivering rotors with enhanced corrosion resistance and durability through the application of a Geomet coating. This coating reduces surface rust and extends rotor life without compromising braking performance. The use of high carbon cast iron in this product line improves heat dissipation and reduces the risk of rotor warping, making it suitable for both daily driving and more demanding conditions.

Common Issues Addressed by This Rotor

• Brake rotor warping and vibration during braking
• Premature rust and corrosion on rotor surfaces
• Reduced braking efficiency due to heat buildup
• Uneven brake pad wear caused by rotor imperfections
• Noise and pulsation from worn or damaged rotors

Installation Notes and Tips

• Ensure the rotor thickness is above the discard thickness of 0.88 inches (22.40 mm) before installation
• Clean mounting surfaces to remove rust or debris for proper rotor seating
• Torque lug nuts to manufacturer specifications to avoid rotor distortion
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Perform a bed-in procedure after installation to maximize braking efficiency
