Technical Details and Construction

The DuraGo BR901948-03 rotor is constructed from cast iron, a material known for its excellent thermal conductivity and wear resistance. This rotor features a full cast design, providing structural integrity and consistent performance under demanding conditions. The vented rotor type allows for improved airflow, reducing heat buildup during braking and helping to maintain optimal brake function. A rust-resistant coating is applied to the rotor surface to minimize corrosion and extend service life, especially in environments exposed to moisture and road salts.

With a non-directional brake surface, this rotor can be installed in either orientation, simplifying replacement. The rotor measures 16.14 inches in outside diameter and has a nominal thickness of 1.27 inches, with a discard thickness of 1.18 inches, indicating when the rotor should be replaced to maintain safe braking performance. The overall height of 2.18 inches ensures proper fitment with the brake caliper assembly.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following vehicles:

• Cadillac Escalade
• Cadillac Escalade ESV
• Chevrolet Silverado 1500
• Chevrolet Tahoe

Designed specifically for these models, the DuraGo BR901948-03 rotor meets the required specifications for mounting bolt hole quantity (6 holes) and dimensions, ensuring a precise fit and reliable braking performance.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Corrosion and rust buildup affecting rotor surface
• Overheating and brake fade from inadequate heat dissipation
• Noise and vibration from uneven rotor wear

Installation Notes and Tips

When installing the DuraGo BR901948-03 rotor, ensure the rotor surface is clean and free of any contaminants before mounting. Verify that the rotor thickness is above the discard thickness specification to maintain safe braking. Since this rotor has a non-directional surface, it can be installed on either side without concern for rotation direction. Always torque mounting bolts to manufacturer specifications and inspect brake pads for wear during rotor replacement.

Quality Assurance and Warranty

DuraGo disc brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The BR901948-03 rotor includes a rust-resistant coating to enhance durability and corrosion resistance. While specific warranty details are not provided, DuraGo products typically come with a limited warranty against defects in materials and workmanship. For optimal performance and safety, use this rotor as a direct replacement on compatible Cadillac and Chevrolet models.
