• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 1.27 inches (32.2 mm) with discard thickness at 1.16 inches (29.4 mm)
• Outside diameter of 12.99 inches (330 mm) ensuring proper fitment
• Five mounting bolt holes with a 4.41 inch (112 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR900872 disc brake rotor is engineered with a full cast iron construction that balances durability and thermal management. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking. This feature is critical for maintaining consistent brake performance and reducing the risk of rotor warping under heavy use. The rotor measures 12.99 inches in outside diameter and has a nominal thickness of 1.27 inches, with a discard thickness of 1.16 inches, indicating when replacement is necessary to maintain safety and performance.

Designed as a conventional rotor without cross-drilled or slotted features, the BR900872 offers a smooth braking surface compatible with a wide range of brake pads. The non-directional surface allows for flexible installation without concern for rotor orientation. This rotor is compatible with multiple Mercedes-Benz models such as the GL320, ML320, ML350, ML450, ML500, R320, R350, and R500, ensuring precise fitment and reliable braking response.

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
• Eliminating noise and vibration from uneven rotor surfaces
• Improving heat dissipation to prevent brake fade during extended use
• Ensuring proper fitment for Mercedes-Benz GL and ML series vehicles

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard specifications
• Clean rotor surface and hub mounting area to prevent uneven contact
• Use proper torque specifications on mounting bolts to avoid rotor distortion
• Check compatibility with existing brake pads and hardware
• Inspect wheel bearings and suspension components during brake service

Quality Assurance and Warranty

DuraGo manufactures the BR900872 rotor to meet or exceed OEM standards for fit, form, and function. The full cast iron construction and vented design contribute to consistent braking performance and durability. While this product does not include a rust-resistant coating, proper maintenance and installation will help extend rotor life. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
