Detailed Product Description

The EBR1031 rotor features a vented design that enhances airflow between the rotor surfaces, helping to reduce heat buildup during braking. With a nominal thickness of 19.90 mm and a discard thickness of 18.40 mm, this rotor maintains structural integrity and braking efficiency throughout its service life. The overall height of 78.60 mm and an outside diameter of 319.80 mm ensure proper fitment within the rear brake assembly of compatible BMW models. The rotor includes a 5-lug hole pattern with a 120 mm bolt circle diameter, matching the factory mounting specifications. Note that this rotor does not include a rust resistant coating, so proper maintenance is recommended to prevent corrosion over time.

Common Applications and Issues Addressed

• Replacement for worn or warped rear brake rotors on BMW X5 and X6
• Restores braking performance affected by rotor thickness below discard limits
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during extended use
• Ensures proper rotor fitment for rear brake assemblies with 5-lug configurations

Installation Notes and Tips

When installing the Power Stop EBR1031 rotor, ensure the rotor thickness is measured and compared to the discard thickness of 18.40 mm to confirm suitability. Clean the rotor surface and hub mounting area to remove any rust or debris before installation. Proper torque specifications should be followed for the 5 mounting lug nuts on the 120 mm bolt circle. Since this rotor does not have a rust resistant coating, consider applying an anti-corrosion treatment to exposed surfaces if the vehicle is operated in harsh environments.
