DuraGo BR900552 Disc Brake Rotor - Rear

Durable Cast Iron Disc Brake Rotor for Volvo Models

The DuraGo BR900552 disc brake rotor is engineered for reliable braking performance on select Volvo vehicles. Designed as a solid, full cast rotor, it offers consistent stopping power for Volvo C30, C70, S40, and V50 models.

• Material: Cast iron for durability and heat dissipation
• Solid rotor construction without slots or cross-drilling
• Nominal thickness of 0.43 inches (11 mm) with discard thickness at 0.35 inches (9 mm)
• Overall height of 1.61 inches (40.8 mm) and outside diameter of 11.02 inches (280 mm)
• Five mounting bolt holes with a 4.25 inch (108 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Technical Details and Compatibility

The DuraGo BR900552 rotor is constructed from full cast iron, providing a balance of strength and thermal management essential for everyday driving conditions. Its solid design means it does not feature venting, slots, or cross-drilled holes, which suits vehicles that do not require enhanced cooling or performance braking modifications. The rotor measures 11.02 inches in diameter and 1.61 inches in overall height, fitting precisely on Volvo C30, C70, S40, and V50 models. The five mounting bolt holes with a 4.25 inch bolt circle diameter ensure secure attachment to the hub assembly. This rotor does not include an ABS tone ring, so it is compatible with vehicles that use separate ABS sensors.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Resolving uneven brake pad wear due to rotor surface issues
• Eliminating noise or vibration related to damaged rotors
• Restoring braking performance on Volvo C30, C70, S40, and V50 vehicles

Installation Notes and Tips

When installing the DuraGo BR900552 rotor, ensure the hub surface is clean and free of rust or debris to promote proper rotor seating. Verify rotor thickness before installation to confirm it meets minimum specifications. Use proper torque settings on the five mounting bolts to avoid rotor warping. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for rotation direction. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system.
