• Nominal thickness of 1.26 inches (32 mm) with discard thickness at 1.18 inches (30 mm)
• Outside diameter of 13.39 inches (340 mm) suitable for specified fitments
• Five mounting bolt holes with a 4.75 inch (120.65 mm) bolt circle diameter
• Non-directional brake surface for flexible installation
• Conventional rotor construction without ABS tone ring

Detailed Product Description

The DuraGo BR900970 disc brake rotor is engineered with a full cast construction using high-quality cast iron, providing a balance of durability and thermal conductivity. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The cross-drilled holes further aid in heat dissipation and help prevent brake fade under demanding conditions. This rotor features a nominal thickness of 1.26 inches (32 mm) and a discard thickness of 1.18 inches (30 mm), ensuring it meets the necessary safety standards for replacement parts.

With an outside diameter of 13.39 inches (340 mm) and five mounting bolt holes arranged on a 4.75 inch (120.65 mm) bolt circle, the BR900970 is designed for direct compatibility with Cadillac Corvette and Chevrolet XLR models. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This conventional rotor does not include an ABS tone ring, so it is intended for vehicles without ABS sensor integration on the rotor.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Improves braking performance by restoring proper rotor thickness and surface condition
• Addresses overheating issues by utilizing vented and cross-drilled design
• Eliminates noise and vibration related to damaged or uneven rotors
• Compatible upgrade for maintaining factory braking specifications on Cadillac Corvette and Chevrolet XLR

Installation Notes and Tips

• Ensure rotor thickness is measured before installation to confirm discard limits
• Clean rotor surface and hub mounting area to prevent uneven rotor seating
• Use proper torque specifications on mounting bolts to avoid rotor warping
• Check brake pads for wear and replace if necessary to optimize braking performance
• Verify compatibility with vehicle ABS system since this rotor does not include an ABS tone ring
