DuraGo BR31288 Disc Brake Rotor - Rear

Overview of DuraGo BR31288 Disc Brake Rotor

The DuraGo BR31288 disc brake rotor is engineered for reliable braking performance on Mitsubishi Montero vehicles. Designed with durable cast iron and a vented, drum-in-hat construction, this rotor supports consistent heat dissipation and structural integrity under demanding driving conditions.

• Material: Cast iron for durability and heat resistance
• Vented rotor design for improved cooling
• Drum-in-hat type rotor with integrated parking brake drum
• Non-directional brake surface for versatile installation
• Six mounting bolt holes with precise fitment dimensions
• Nominal thickness of 0.87 inches (22 mm) with discard thickness at 0.8 inches (20.4 mm)
• Overall diameter of 11.81 inches (300 mm) and height of 2.83 inches (72 mm)

Detailed Product Description

The DuraGo BR31288 rotor is constructed from full cast iron, providing a solid and reliable braking surface for Mitsubishi Montero models. Its vented design enhances airflow between the rotor faces, helping to reduce heat buildup during braking and maintain consistent stopping power. The drum-in-hat construction integrates a parking brake drum, eliminating the need for a separate component and simplifying installation. This rotor features a non-directional brake surface, allowing it to be installed on either side of the vehicle without concern for directional wear patterns.

With six mounting bolt holes arranged on a 139.7 mm (5.5 inch) bolt circle diameter, and a center hole diameter of 94 mm (3.7 inches), the BR31288 rotor ensures precise fitment on compatible Mitsubishi Montero models. The nominal thickness of 0.87 inches (22 mm) and discard thickness of 0.8 inches (20.4 mm) provide clear guidelines for rotor service life and replacement timing.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thinning
• Resolving noise issues related to uneven rotor surfaces
• Upgrading to a vented rotor for improved heat dissipation
• Restoring parking brake functionality with drum-in-hat design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility specifically with Mitsubishi Montero models
• Inspect brake pads and hardware during rotor replacement for optimal performance

Quality Assurance and Warranty

DuraGo manufactures the BR31288 rotor to meet industry standards for material quality and dimensional accuracy. While this rotor does not include a rust-resistant coating, its cast iron construction is designed for durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
