DuraGo BR31123 Disc Brake Rotor - Front

Durable Cast Iron Disc Brake Rotor for Nissan 200SX and Sentra

The DuraGo BR31123 disc brake rotor is engineered to provide reliable braking performance for Nissan 200SX and Sentra models. Constructed from full cast iron, this vented rotor offers consistent heat dissipation and durability under normal driving conditions.

• Material: Full cast iron construction for strength and heat resistance
• Vented design to improve cooling and reduce brake fade
• Nominal thickness of 0.71 inches (18 mm) with discard thickness at 0.63 inches (16 mm)
• Overall height of 1.77 inches (45 mm) and outside diameter of 9.13 inches (232 mm)
• Four mounting bolt holes with a 100 mm (3.94 inch) bolt circle diameter
• Non-directional brake surface suitable for standard brake pad applications
• Conventional rotor type without ABS tone ring, cross-drilled, or slotted features

Technical Details and Construction

The DuraGo BR31123 rotor is designed as a conventional, vented disc brake rotor made from cast iron, which is known for its ability to withstand high temperatures and resist warping. The vented construction allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking. This rotor features a nominal thickness of 0.71 inches (18 mm) and a discard thickness of 0.63 inches (16 mm), ensuring it meets safety standards for replacement. The overall height measures 1.77 inches (45 mm), and the outside diameter is 9.13 inches (232 mm), matching OEM specifications for Nissan 200SX and Sentra vehicles. The rotor includes four mounting bolt holes with a 100 mm bolt circle diameter, compatible with the specified Nissan models.

Compatible Nissan Models and Applications

This disc brake rotor is compatible with Nissan 200SX and Sentra models, providing a direct replacement for worn or damaged rotors. It is designed for vehicles that require a conventional, vented rotor without ABS tone rings or specialized surface treatments like slotted or cross-drilled patterns.

• Replaces worn or warped rotors causing brake pulsation or noise
• Addresses reduced braking efficiency due to rotor thickness below discard limits
• Solves issues related to overheating and brake fade during normal driving
• Restores proper rotor dimensions for safe and consistent braking

Installation Notes and Tips

When installing the DuraGo BR31123 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper fitment. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness. Use appropriate torque specifications for the mounting bolts to avoid rotor distortion. This rotor is non-directional, so it can be installed on either side of the vehicle without concern for rotation direction.

Quality Assurance and Warranty

DuraGo disc brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function. While this product does not include a rust-resistant coating, the cast iron construction provides reliable durability under typical operating conditions. Warranty coverage details should be confirmed with the product documentation or supplier.
