Detailed Product Description

The DuraGo BR55112 rotor is constructed from full cast iron, providing a robust and durable braking surface suitable for heavy-duty use. Its vented design enhances airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and reduces the risk of rotor warping. With a nominal thickness of 1.14 inches and a discard thickness of 1.08 inches, this rotor meets OEM specifications for thickness tolerances, ensuring safe and effective braking performance. The rotor’s 6-bolt mounting pattern and 11.89-inch diameter make it compatible with a range of mid-size SUVs and trucks, including the Chevrolet Trailblazer and GMC Envoy.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following makes and models:

• Buick Rainier
• Chevrolet Trailblazer and SSR
• GMC Envoy
• Isuzu Ascender

It is designed for vehicles requiring a conventional, vented rotor without ABS tone ring integration.

Common Issues Addressed by DuraGo BR55112

• Brake rotor warping due to heat buildup
• Uneven brake pad wear caused by rotor thickness variation
• Reduced braking efficiency from worn or undersized rotors
• Brake noise and vibration linked to rotor surface irregularities
• Compatibility issues with OEM mounting bolt patterns

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.08 inches) before installation
• Clean mounting surface to prevent rotor runout and vibration
• Use proper torque specifications on the 6 mounting bolts
• Check for compatibility with vehicle’s brake caliper and hub assembly
• Inspect brake pads and replace if worn to optimize rotor performance
