Detailed Product Description

The DuraGo BR901874 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface for Tesla Model 3 vehicles. Its vented design enhances airflow between the rotor surfaces, helping to reduce heat buildup during braking and maintain consistent performance. With a nominal thickness of 0.79 inches (20 mm) and a discard thickness of 0.71 inches (18 mm), this rotor meets the specifications required for safe and effective brake operation. The rotor features a 13.19 inch (335 mm) outside diameter and an overall height of 1.87 inches (47.4 mm), ensuring proper fitment and compatibility with Tesla Model 3 brake assemblies. The 5 mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter and 0.66 inch (16.7 mm) hole diameter provide secure attachment to the vehicle hub. This rotor is designed with a non-directional braking surface and is a conventional type, meaning it is not a drum-in-hat style rotor. Note that this rotor does not include a rust resistant coating or an ABS tone ring.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors on Tesla Model 3
• Improves braking performance by restoring proper rotor thickness
• Helps reduce brake noise and vibration caused by uneven rotor surfaces
• Addresses overheating issues through vented rotor design
• Ensures safe braking by meeting Tesla Model 3 OEM specifications

Installation Notes and Tips

When installing the DuraGo BR901874 rotor on a Tesla Model 3, ensure the rotor surface is clean and free of any contaminants before mounting. Verify that the rotor thickness is above the discard limit of 0.71 inches (18 mm) to maintain safe braking performance. Use the correct torque specifications for the 5 mounting bolts to avoid rotor warping. 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 ensure optimal braking efficiency.
