• Brake Surface: Non-directional, drum-in-hat type rotor

Technical Details and Construction

The DuraGo BR900740 rotor is made from cast iron, a material known for its excellent heat absorption and resistance to warping under high temperatures. Its full cast construction ensures a solid and reliable rotor body, while the vented design allows air to flow through the rotor, helping to dissipate heat more effectively during braking. This rotor features a drum-in-hat design, integrating the parking brake drum within the rotor assembly, which is compatible with the BMW X5's braking system. The non-directional brake surface means the rotor can be installed on either side of the vehicle without affecting performance.

Compatible Applications and Problem Solving

This disc brake rotor is specifically compatible with BMW X5 models requiring part number BR900740. It addresses common braking issues such as:

• Brake fade caused by overheating during extended use
• Uneven rotor wear leading to vibration or noise
• Warped rotors resulting in pulsation during braking
• Reduced braking efficiency due to worn or thin rotors
• Integration with parking brake systems via the drum-in-hat design

Installation Notes and Tips

When installing the DuraGo BR900740 rotor on your BMW X5, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness before installation to confirm it meets the nominal thickness of 0.79 inch (20 mm) and is above the discard thickness of 0.72 inch (18.4 mm). Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. Proper torque specifications should be followed for the 5 mounting bolts to ensure secure installation.

Quality Assurance and Warranty

DuraGo manufactures the BR900740 rotor to meet industry standards for performance and durability. While this rotor does not feature a rust-resistant coating, its cast iron construction provides reliable service life under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
