Detailed Product Description

The DuraGo BR31225 rotor is a solid, full cast iron disc designed specifically for Mitsubishi Diamante vehicles. Its drum-in-hat construction integrates a parking brake drum within the rotor, providing a compact and efficient braking solution. The rotor measures 10.16 inches in outside diameter and features a nominal thickness of 0.41 inches, ensuring adequate material for wear and heat management. The discard thickness is set at 0.32 inches, indicating when the rotor should be replaced to maintain safe braking performance. This rotor does not include rust-resistant coating, so proper maintenance is recommended to prevent corrosion over time. 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 on Mitsubishi Diamante models
• Restores braking efficiency and pedal feel
• Addresses brake noise caused by uneven rotor surfaces
• Solves vibration issues during braking due to rotor runout
• Supports parking brake function with integrated drum-in-hat design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent rotor misalignment
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with existing brake pads and hardware
• Inspect wheel bearings and hub assembly during rotor replacement

Quality Assurance and Warranty

DuraGo disc brake rotors are manufactured to meet OEM specifications for fit and function on Mitsubishi Diamante vehicles.
