• Vented design for improved heat dissipation
• Nominal thickness of 1.04 inches (26.3 mm)
• Outside diameter of 10.51 inches (267 mm)
• Five mounting bolt holes with 4.53 inch (115 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Features and Specifications

The DuraGo BR5566 rotor features a full cast iron construction, providing the necessary strength and thermal capacity for effective braking. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to prevent brake fade. The rotor measures 10.51 inches (267 mm) in outside diameter and has a nominal thickness of 1.04 inches (26.3 mm), with a discard thickness of 0.97 inches (24.7 mm) indicating when replacement is necessary. The overall height is 1.42 inches (36 mm), and it includes five mounting bolt holes with a 4.53 inch (115 mm) bolt circle diameter and 0.51 inch (13 mm) hole diameter. This rotor does not include an ABS tone ring and features a non-directional brake surface, allowing for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

This disc brake rotor is compatible with a range of GM vehicles, specifically:

• Buick Cutlass Supreme
• Chevrolet Lumina and Monte Carlo
• Oldsmobile Cutlass Supreme and Regal
• Pontiac Grand Prix

It is designed to meet the braking requirements of these models, ensuring proper fit and function when replacing worn or damaged rotors.

Common Issues Addressed by DuraGo BR5566 Rotor

• Brake pulsation or vibration caused by warped rotors
