Detailed Product Description

The DuraGo BR55047 is a full cast iron disc brake rotor designed to meet the braking demands of mid-size SUVs and trucks. Its vented construction allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The rotor’s nominal thickness of 1.15 inches (29.1 mm) ensures structural integrity, while the discard thickness of 1.08 inches (27.5 mm) indicates when replacement is necessary to maintain safe braking performance.

With an outside diameter of 10.79 inches (274 mm) and an overall height of 2.15 inches (54.7 mm), this rotor fits vehicles equipped with a five-bolt mounting pattern and a 4.75 inch (120.65 mm) bolt circle diameter. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This rotor does not include a rust-resistant coating or ABS tone ring, making it suitable for vehicles that do not require these features.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with a range of Chevrolet, GMC, Isuzu, and Oldsmobile models, including:

• Chevrolet Blazer
• GMC Jimmy
• Isuzu Hombre
• Chevrolet S10
• GMC Sonoma
• Oldsmobile Bravada

It is designed to replace worn or damaged rotors on these vehicles, restoring braking efficiency and safety.

Common Issues Addressed by BR55047 Rotor

• Brake pulsation or vibration caused by warped rotors
• Reduced braking performance due to rotor wear below discard thickness
• Overheating and brake fade from insufficient heat dissipation
• Uneven brake pad wear linked to rotor surface irregularities
• Noise or squealing related to rotor surface damage

Installation Notes and Tips

• Ensure rotor thickness is measured before installation to confirm it meets minimum specifications
• Clean rotor mounting surface and hub to prevent runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Perform a proper bed-in procedure after installation to maximize braking efficiency
