Durable Cast Iron Disc Brake Rotor for GM SUVs

The DuraGo BR900322 disc brake rotor is engineered for reliable braking performance on select Buick, Chevrolet, GMC, and Saturn SUVs. Designed with vented construction and precise dimensions, this rotor supports consistent heat dissipation and long service life for vehicles like the Buick Enclave and Chevrolet Traverse.

• Material: Full cast iron construction for durability
• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 1.14 inches (29 mm) with discard thickness at 1.08 inches (27.5 mm)
• Outside diameter of 12.8 inches (325 mm) suitable for specific GM SUV models
• Six mounting bolt holes with a 5.2 inch (132 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Technical Details and Specifications

The DuraGo BR900322 rotor features a full cast iron construction that provides strength and resistance to warping under high temperatures. Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation during braking. The rotor measures 12.8 inches (325 mm) in outside diameter and has an overall height of 2.15 inches (54.5 mm). The nominal thickness is 1.14 inches (29 mm), with a discard thickness of 1.08 inches (27.5 mm), indicating when replacement is necessary to maintain safe braking performance.

Mounting is facilitated by six bolt holes with a diameter of 0.62 inches (15.8 mm) arranged on a 5.2 inch (132 mm) bolt circle diameter. The center hole diameter is 2.98 inches (75.6 mm). This rotor is designed as a conventional, non-directional brake surface without cross-drilling or slotting, making it compatible with original equipment brake pads and calipers.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with a range of GM SUVs, including:

• Buick Enclave
• Chevrolet Acadia and Acadia Limited
• Chevrolet Traverse
• GMC Acadia
• Saturn Outlook

It is intended for use in front or rear disc brake systems where the original equipment rotor matches these specifications.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Reduced braking efficiency due to worn or thin rotors
• Overheating and brake fade from insufficient heat dissipation
• Uneven brake pad wear linked to rotor surface irregularities
• Noise and pulsation caused by damaged or scored rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Use proper torque specifications on mounting bolts to avoid distortion
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Perform a bed-in procedure after installation to optimize braking performance
