Durable Construction and Precise Specifications

The BR55069-01 rotor features a full cast iron construction that balances durability with effective heat management. Its vented design helps reduce brake fade by allowing air to circulate and cool the rotor during operation. The rotor measures 12.01 inches (305 mm) in outside diameter with an overall height of 2.14 inches (54.3 mm), ensuring proper fitment and clearance. Nominal thickness is 1.15 inches (29.1 mm), with a discard thickness of 1.08 inches (27.5 mm), indicating when replacement is necessary to maintain braking efficiency. The rotor includes six mounting bolt holes arranged on a 5-inch (127 mm) bolt circle diameter, with each hole measuring 0.52 inches (13.2 mm) in diameter. This conventional, non-directional rotor does not include an ABS tone ring and is designed for vehicles requiring a solid, vented rotor without cross-drilled or slotted features.

Compatible Vehicles and Applications

• Buick Ascender
• Chevrolet Trailblazer
• GMC Envoy
• Isuzu Ascender
• Oldsmobile Bravada and Rainier

This rotor is suitable for drivers seeking a reliable replacement part for their disc brake system on these specific models, ensuring proper fit and function.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced braking performance
• Corrosion and rust buildup affecting rotor surface
• Overheating and brake fade during extended use
• Uneven rotor thickness causing noise or pulsation

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.08 inches (27.5 mm) before installation. Clean the hub surface to remove rust and debris for proper rotor seating. Use the six mounting bolts to secure the rotor on the 5-inch bolt circle diameter. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for rotation direction. Verify compatibility with your vehicle’s brake system and ABS components, as this rotor does not include an ABS tone ring.
