Technical Details and Construction
The BR901990 rotor features a full cast iron construction, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, reducing heat buildup and helping to maintain braking efficiency during extended use. The rotor’s nominal thickness of 0.79 inches (20 mm) ensures a robust braking surface, while the discard thickness of 0.71 inches (18 mm) indicates when replacement is necessary to maintain safety and performance. With an outside diameter of 13.58 inches (345 mm) and an overall height of 1.26 inches (32 mm), this rotor is engineered for precise compatibility with Genesis Electrified GV70, G80, G90, and GV70 models.
Compatible Vehicles and Applications
This DuraGo disc brake rotor is specifically designed for use with the following Genesis vehicles:
- Genesis Electrified GV70
- Genesis G80
- Genesis G90
- Genesis GV70
It is ideal for addressing common braking issues such as:
- Brake rotor wear and thinning beyond discard thickness
- Overheating and brake fade during heavy use
- Uneven braking or vibration caused by warped rotors
- Replacement of worn or damaged conventional rotors
Installation Notes and Tips
When installing the DuraGo BR901990 rotor, ensure the mounting surface is clean and free of debris to promote proper seating. This rotor features a non-directional brake surface, allowing installation on either side without concern for rotation direction. Verify that the rotor thickness is within specifications before installation, and replace if below the discard thickness of 0.71 inches (18 mm). Proper torque on the five mounting bolts with a 4.5 inch (114.3 mm) bolt circle diameter is essential for safe operation.
