Detailed Product Description
The DuraGo BR5556 disc brake rotor is constructed from full cast iron, a material known for its strength and ability to withstand high temperatures generated during braking. Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation and reducing the risk of brake fade during extended use. This rotor features a drum-in-hat design, integrating a parking brake drum within the rotor hat, which is compatible with Chevrolet Corvette models requiring this configuration.
With a nominal thickness of 0.79 inches (20 mm) and a discard thickness of 0.72 inches (18.4 mm), the rotor provides a balance between longevity and performance. The overall height of 2.51 inches (63.8 mm) and an outside diameter of 11.5 inches (292 mm) ensure proper fitment and compatibility. The five mounting bolt holes, each measuring 0.52 inches (13.1 mm) in diameter, are arranged on a 4.75 inch (120.65 mm) bolt circle diameter, matching the factory specifications for the Chevrolet Corvette.
Compatible Vehicles and Applications
This DuraGo BR5556 rotor is specifically designed for Chevrolet Corvette models requiring a vented, drum-in-hat disc brake rotor. It is suitable for applications where a rust-resistant coating is not necessary, and the rotor does not include an ABS tone ring. The non-directional brake surface allows for flexible installation without concern for rotor orientation.
Common Issues Addressed by DuraGo BR5556 Rotor
- Brake fade caused by overheating during aggressive or prolonged braking
- Uneven brake pad wear due to rotor warping or thickness variation
- Reduced braking efficiency from worn or undersized rotors
- Parking brake malfunction related to integrated drum-in-hat rotor design
- Noise and vibration issues stemming from rotor surface irregularities
Installation Notes and Tips
- Ensure rotor thickness is above discard thickness (0.72 inches) before installation
- Clean rotor mounting surface to prevent runout and vibration
- Use proper torque specifications for the five mounting bolts
- Check compatibility with existing brake pads and parking brake components
- Inspect wheel bearings and hub assembly during rotor replacement
