Detailed Product Description

The DuraGo BR55049 rotor is designed specifically for use on Chevrolet Blazer and GMC Jimmy vehicles, ensuring proper fitment and optimal braking performance. Its full cast iron construction provides excellent thermal conductivity and durability under normal driving conditions. The vented design helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. This rotor features a drum-in-hat configuration, combining the disc braking surface with an integrated drum for parking brake functionality.

With a nominal thickness of 0.79 inches (20 mm) and a discard thickness of 0.73 inches (18.5 mm), this rotor meets OEM specifications for thickness tolerances. The 5 mounting bolt holes with a 4.75 inch (120.65 mm) bolt circle diameter ensure secure attachment to the hub assembly. The non-directional brake surface allows for flexible installation without concern for rotor orientation. Note that this rotor does not include an ABS tone ring and does not have rust-resistant coating, so proper maintenance is recommended to prevent corrosion.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores braking efficiency on Chevrolet Blazer and GMC Jimmy models
• Addresses rotor thickness below manufacturer discard limits
• Improves heat dissipation to reduce brake fade during heavy braking
• Supports parking brake function with integrated drum-in-hat design

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard specifications
• Clean mounting surface and hub to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to maintain balanced braking performance
• Check for ABS sensor compatibility as this rotor does not include an ABS tone ring
