Technical Details and Construction

The DuraGo BR31273-01 rotor features a solid, non-vented design with a drum-in-hat configuration, which integrates the parking brake drum into the rotor hat. This design is common in Subaru vehicles like the Baja, Legacy, and Outback, providing a compact and efficient braking system. The rotor’s cast iron material ensures effective heat dissipation and structural integrity during braking. The rust-resistant coating extends the rotor’s service life by reducing surface corrosion, which is especially beneficial in regions with harsh weather conditions.

Compatible Subaru Models and Applications

This disc brake rotor is specifically compatible with the following Subaru models:

• Subaru Baja
• Subaru Legacy
• Subaru Outback

It is designed to meet the exact specifications required for these vehicles, ensuring proper fitment and reliable braking performance. The part number BR31273-01 should be referenced when searching for replacement rotors for these models.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced braking efficiency
• Corrosion and rust buildup on rotor surfaces
• Uneven brake pad wear due to rotor surface irregularities
• Noise or squealing caused by damaged or worn rotors

Installation Notes and Tips

When installing the DuraGo BR31273-01 rotor, ensure the mounting surface is clean and free of debris to promote proper seating. Verify that the rotor thickness is above the discard thickness of 0.33 inches (8.5 mm) before installation. Use the correct torque specifications for the 5 mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
