Overview of DuraGo BR900686 Disc Brake Rotor

The DuraGo BR900686 disc brake rotor is engineered for reliable braking performance on select Audi models. Designed with durable cast iron and a vented construction, this rotor supports effective heat dissipation and consistent stopping power for vehicles like the Audi A4, A4 Quattro, A6 Quattro, Allroad Quattro, and S4.

• Material: Cast iron for strength and durability
• Vented rotor design to improve heat dissipation
• Nominal thickness of 30 mm with discard thickness at 28 mm
• Outside diameter of 320 mm (12.6 inches)
• Five mounting bolt holes with a 112 mm bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional full cast construction
• Center hole diameter of 68 mm (2.68 inches)

Technical Details and Construction

The BR900686 rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, reducing heat buildup during braking and helping to maintain consistent performance under demanding conditions. The rotor measures 320 mm in outside diameter and has a nominal thickness of 30 mm, with a discard thickness of 28 mm, ensuring it meets specifications for safe replacement intervals. The five mounting bolt holes are spaced on a 112 mm bolt circle diameter, compatible with the specified Audi models. This rotor features a non-directional brake surface, allowing installation on either side of the vehicle without concern for directional orientation.

Compatible Audi Models and Applications

This DuraGo disc brake rotor is compatible with a range of Audi vehicles, including the A4, A4 Quattro, A6 Quattro, Allroad Quattro, and S4. It is designed to replace original equipment rotors on these models, providing a direct fit and maintaining factory braking performance. The part number BR900686 should be referenced to ensure proper fitment for these specific Audi vehicles.

• Replaces worn or warped rotors causing brake pulsation
• Addresses rotor thickness below manufacturer discard limits
• Improves braking consistency and reduces noise
• Restores proper rotor surface for even pad wear
• Eliminates vibration or shudder during braking

Installation Notes and Tips

When installing the DuraGo BR900686 rotor, ensure the rotor surface is clean and free of any contaminants before mounting. Verify that the rotor thickness meets or exceeds the nominal thickness of 30 mm and is above the discard thickness of 28 mm. Use proper torque specifications for the five mounting bolts on the 112 mm bolt circle diameter. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for orientation. It is recommended to inspect brake pads and hardware during installation to ensure optimal braking system performance.
