Detailed Product Description

The DuraGo BR34180 disc brake rotor is constructed from high-quality cast iron, providing a solid and durable braking surface. Its full cast construction ensures consistent thickness and strength, while the solid rotor design offers straightforward maintenance without the complexity of vented or slotted rotors. The drum-in-hat configuration integrates a parking brake drum, making it suitable for BMW X5 vehicles equipped with this braking system. With an outside diameter of 12.76 inches and a nominal thickness of 0.47 inches, this rotor meets OEM specifications for fit and function. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This rotor does not include an ABS tone ring and does not feature rust-resistant coating, so proper care and installation are recommended to maintain longevity.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving noise or vibration issues linked to damaged or uneven rotor surfaces
• Upgrading to OEM-spec rotors for consistent braking performance on BMW X5
• Ensuring compatibility with drum-in-hat parking brake systems

Installation Notes and Tips

• Verify rotor thickness before installation; discard thickness is 0.41 inches (10.4 mm)
• Ensure mounting bolt holes align with the 5-bolt pattern and 120 mm bolt circle diameter
• Clean rotor surface and hub mounting area to prevent uneven wear or noise
• Check for proper torque specifications on mounting bolts to avoid rotor warping
• Since this rotor lacks rust-resistant coating, consider applying anti-corrosion treatment if exposed to harsh environments

Quality Assurance and Warranty

DuraGo manufactures the BR34180 rotor to meet or exceed OEM standards for fit, form, and function on BMW X5 vehicles. While this rotor does not include a rust-resistant coating, its cast iron construction provides reliable durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation to ensure protection against defects.
