Detailed Product Description

The DuraGo BR31377-01 disc brake rotor is specifically designed for Toyota Prius vehicles, ensuring compatibility and optimal braking performance. Constructed from full cast iron, this rotor offers a balance of strength and thermal conductivity. The vented design enhances airflow, helping to dissipate heat generated during braking and reducing the risk of brake fade. A rust-resistant coating is applied to the rotor surface to protect against corrosion, which is especially beneficial in humid or wet environments.

With a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.79 inches (20 mm), this rotor meets precise wear specifications to maintain safe braking performance. The 10.04 inch (255 mm) outside diameter and five mounting bolt holes with a 3.94 inch (100 mm) bolt circle diameter ensure a secure fit on compatible Toyota Prius models. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust buildup
• Improving heat dissipation to reduce brake fade during extended use
• Restoring braking performance on Toyota Prius models with original equipment rotor wear
• Ensuring proper rotor thickness for safe braking operation

Installation Notes and Tips

• Verify compatibility with Toyota Prius model year before installation
• Inspect brake pads and replace if worn to ensure even rotor wear
• Clean mounting surfaces to prevent rotor misalignment
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check rotor thickness and discard limits during installation
