Durable Cast Iron Disc Brake Rotor for GM Trucks and SUVs

The DuraGo BR55097 disc brake rotor is engineered for reliable braking performance on select Cadillac, Chevrolet, and GMC models. Designed with a full cast iron construction and vented design, this rotor provides consistent heat dissipation and durability for vehicles like the Chevrolet Silverado 1500 and GMC Sierra 1500.

• Material: Full cast iron for strength and heat resistance
• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 30.2 mm with discard thickness at 28 mm
• Outside diameter of 330 mm (12.99 inches) for precise fitment
• 6 mounting bolt holes with a 139.7 mm bolt circle diameter
• Non-directional brake surface for versatile installation
• Compatible with multiple GM models including Cadillac Escalade and Chevrolet Tahoe

Technical Details and Construction

The BR55097 rotor features a full cast iron construction, providing the necessary rigidity and thermal capacity to withstand demanding braking conditions. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat more effectively and maintain braking performance during extended use. The rotor measures 330 mm in outside diameter and has a nominal thickness of 30.2 mm, with a discard thickness of 28 mm to ensure safe replacement intervals. The overall height is 55.6 mm, and it includes six mounting bolt holes with a 139.7 mm bolt circle diameter, matching factory specifications for a secure fit.

Compatible Vehicles and Applications

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

• Cadillac Escalade, Escalade ESV, Escalade EXT, and XTS
• Chevrolet Avalanche, Silverado 1500 (including Classic and LD), Suburban 1500, Tahoe, and Express 1500
• GMC Sierra 1500 (Classic, Limited), Yukon, Yukon XL, Yukon XL 1500, and Savana 1500

It is designed for conventional, non-directional brake surfaces and does not include an ABS tone ring, making it suitable for vehicles with standard braking systems.

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 out-of-spec rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (28 mm) before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fit
• Inspect brake pads and replace if worn to maintain optimal braking
• Check for ABS sensor compatibility as this rotor does not include a tone ring
