Detailed Product Description

The DuraGo BR900856 is a conventional, vented disc brake rotor made from cast iron, providing a balance of durability and thermal management. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The rotor measures 11.89 inches in outside diameter and 1.61 inches in overall height, fitting securely on Volvo S60, S80, V60, V70, and XC70 models. With five mounting bolt holes spaced on a 4.25 inch bolt circle diameter, installation aligns precisely with factory specifications. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible placement on either side of the vehicle.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Restores braking efficiency on Volvo S60, S80, V60, V70, and XC70 models
• Addresses rotor thickness below discard limits to maintain safety
• Improves heat dissipation to reduce brake fade during extended use
• Eliminates noise and vibration associated with damaged rotors

Installation Notes and Tips

• Ensure rotor thickness is within nominal specifications before installation
• Clean mounting surfaces to prevent uneven rotor seating
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with existing brake pads and hardware
• Inspect calipers and brake lines during rotor replacement for overall system health
