• Vented design to improve cooling and reduce brake fade
• Drum-in-hat type rotor with integrated parking brake drum
• Non-directional brake surface for versatile installation
• Five mounting bolt holes with a 114.3 mm bolt circle diameter
• Outside diameter of 291 mm (11.46 inches) and overall height of 68 mm (2.68 inches)
• Nominal thickness of 18 mm (0.71 inches) with discard thickness at 17 mm (0.67 inches)
• Center hole diameter of 60 mm (2.36 inches) for precise fitment

Technical Details and Construction

The DuraGo BR31157 rotor is made from cast iron, a material known for its excellent thermal conductivity and wear resistance. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking. This reduces the risk of brake fade and maintains consistent stopping power. The rotor features a drum-in-hat construction, integrating a parking brake drum within the rotor hat, which is compatible with specific Toyota Previa and Supra brake systems. The non-directional brake surface simplifies installation by allowing the rotor to be mounted in either orientation without affecting performance.

Compatible Vehicles and Applications

• Designed specifically for Toyota Previa models requiring a 291 mm vented disc brake rotor
• Compatible with Toyota Supra models that use a drum-in-hat type rotor
• Ideal replacement for worn or damaged rotors to restore braking efficiency
• Suitable for vehicles experiencing brake noise, vibration, or reduced stopping power
• Addresses rotor thickness wear by meeting nominal and discard thickness specifications

Installation Notes and Tips

When installing the DuraGo BR31157 rotor, ensure the rotor thickness is above the discard thickness of 17 mm to maintain safe braking performance. The rotor's non-directional design allows for flexible mounting orientation. Verify that the five mounting bolt holes align with the vehicle's 114.3 mm bolt circle diameter. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle's ABS system. Proper cleaning of the rotor surface before installation is recommended to remove any protective coatings or contaminants.

Quality Assurance and Warranty

DuraGo manufactures the BR31157 rotor to meet or exceed OEM specifications for fit, form, and function. The full cast iron construction ensures durability and consistent performance over time. While no specific warranty information is provided, DuraGo products typically undergo rigorous quality control to ensure reliability in automotive braking applications.
