Technical Details and Construction

The DuraGo BR901938-01 rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design enhances heat dissipation during braking, reducing the risk of brake fade under heavy use. The rotor measures 13.15 inches in outside diameter and 3.25 inches in overall height, matching OEM specifications for Chevrolet Canyon and GMC Colorado vehicles. The nominal thickness of 0.91 inches ensures optimal performance, while the discard thickness of 0.83 inches indicates when replacement is necessary to maintain safety and braking efficiency. The rotor features six mounting bolt holes arranged on a 4.72 inch bolt circle diameter, compatible with the specified vehicle models.

Compatible Vehicles and Applications

This disc brake rotor is specifically designed for use on Chevrolet Canyon and GMC Colorado trucks. It is suitable for drivers seeking a reliable replacement rotor that meets factory specifications for these models. The DuraGo BR901938-01 rotor addresses common braking issues such as:

• Brake rotor wear and thinning beyond discard thickness
• Corrosion and rust buildup on braking surfaces
• Overheating and brake fade during heavy braking
• Uneven rotor surface causing vibration or noise
• Replacement of worn or damaged OEM rotors

Installation Notes and Tips

When installing the DuraGo BR901938-01 rotor, ensure the rotor surface is clean and free of debris before mounting. Verify that the rotor thickness is above the discard thickness specification to maintain safe braking performance. This rotor is non-directional, allowing installation on either side of the vehicle without concern for rotation direction. Use proper torque specifications for the six mounting bolts to secure the rotor firmly. It is recommended to inspect brake pads and hardware during installation to ensure overall system integrity.
