Detailed Product Description

The DuraGo BR3489 disc brake rotor is crafted from cast iron, a material known for its ability to withstand high temperatures and provide stable braking under various driving conditions. This rotor features a solid, non-directional braking surface, which means it can be installed on either side of the vehicle without affecting performance. The drum-in-hat construction integrates a drum brake surface within the rotor hat, allowing compatibility with vehicles equipped with rear drum parking brakes.

With an outside diameter of 11.06 inches and an overall height of 2.88 inches, this rotor fits Volvo models such as the 240, 740, 745, 760, 780, 940, 960, DL, and GLE. The 5 mounting bolt holes with a 4.25 inch bolt circle diameter ensure secure attachment to the wheel hub. The nominal thickness of 0.38 inches provides a solid braking surface, while the discard thickness of 0.33 inches indicates when the rotor should be replaced to maintain safe braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing uneven brake pad wear due to rotor surface irregularities
• Restoring proper braking performance on Volvo 240 and 700 series vehicles
• Eliminating brake noise caused by rotor damage or corrosion
• Ensuring compatibility with drum-in-hat parking brake systems

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean mounting surface and hub to prevent rotor runout and vibration
• Use proper torque specifications on mounting bolts to avoid rotor distortion
• Check compatibility with vehicle ABS system; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
