• Overall height: 1.82 in. (46.3 mm)

Detailed Description

DuraGo BR31287 is part of the brand’s brake drum and rotor program, built in ISO-certified factories with attention to fit, form, and function. For Mitsubishi Montero front brake service, this rotor follows the required dimensions for proper wheel-end fitment and braking surface alignment. The vented cast iron design supports heat management during repeated stops, while the non-directional surface helps promote even pad bedding and consistent braking feel. This part cross-references GSP 126073 for the same application.

Compatible With 2000 Mitsubishi Montero, front from 2/00, and 2001-2006 Mitsubishi Montero, front. The BR31287 is a direct replacement choice when servicing front brake rotors on these Montero model years.

What This Rotor Helps Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking performance from a worn front rotor surface
• Noise related to uneven rotor contact with brake pads
• Heat buildup in front brake service applications
• Fitment issues when replacing the original front rotor on select Mitsubishi Montero models

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub fitment before installation. Clean the hub mounting surface thoroughly to help prevent lateral runout and brake pedal vibration. Inspect pads, calipers, and hardware condition during rotor replacement, and follow the vehicle manufacturer’s torque specifications and bedding procedure after installation.

Quality Assurance

DuraGo manufactures this rotor through ISO-certified factories and builds its brake program around catalog accuracy and OE-style fitment requirements. The BR31287 is produced to meet fit, form, and function expectations for front brake service on the listed Mitsubishi Montero applications.
