DuraGo BR31029-01 Disc Brake Rotor - Front

Durable Cast Iron Disc Brake Rotor for Honda Vehicles

The DuraGo BR31029-01 disc brake rotor is engineered to provide reliable braking performance for select Honda models. Designed with a full cast construction and rust-resistant coating, this vented rotor ensures consistent heat dissipation and long-lasting durability for your Honda Civic, Civic del Sol, and CRX.

• Material: Cast iron for strength and heat resistance
• Vented design to improve cooling and reduce brake fade
• Rust-resistant coating to protect against corrosion
• Nominal thickness of 0.83 inches (21 mm) with discard thickness at 0.75 inches (19 mm)
• Overall diameter of 9.45 inches (240 mm) with 4 mounting bolt holes
• Non-directional brake surface for versatile installation
• Conventional rotor type compatible with drum-in-hat systems

Technical Details and Construction

The DuraGo BR31029-01 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, helping to dissipate heat generated during braking and reducing the risk of brake fade. The rotor features a rust-resistant coating that helps maintain its appearance and performance over time, especially in environments prone to moisture and road salt.

With an outside diameter of 240 mm (9.45 inches) and an overall height of 44.1 mm (1.74 inches), this rotor fits Honda Civic, Civic del Sol, and CRX models requiring a 4-bolt mounting pattern with a 100 mm (3.94 inches) bolt circle diameter. The nominal thickness is 21 mm (0.83 inches), and the discard thickness is 19 mm (0.75 inches), ensuring clear guidelines for rotor replacement.

Compatible Honda Models and Applications

• Honda Civic (various years requiring 240 mm vented rotors)
• Honda Civic del Sol
• Honda CRX

This rotor is designed specifically for these Honda models, providing a direct replacement that meets factory specifications for fit and function.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive brake fade due to poor heat dissipation
• Corrosion and rust buildup on rotor surfaces
• Worn or thin rotors below discard thickness limits
• Uneven braking performance or noise from damaged rotors

Installation Notes and Tips

Ensure the rotor mounting surface is clean and free of debris before installation. Verify the rotor thickness is above the discard limit of 19 mm (0.75 inches) to maintain safe braking performance. This rotor features a non-directional braking surface, allowing installation on either side without concern for rotation direction. Use proper torque specifications for the 4 mounting bolts to avoid rotor distortion.
