Product Details and Specifications

The DuraGo BR54143-01 rotor features a vented design that enhances heat dissipation during braking, helping to maintain consistent performance and reduce the risk of brake fade. Its full cast iron construction provides the necessary strength and durability for daily driving and demanding conditions. The rotor includes a rust-resistant coating to protect against corrosion, which is especially beneficial in wet or humid environments.

With a nominal thickness of 1.18 inches (30 mm) and a discard thickness of 1.12 inches (28.5 mm), this rotor meets OEM specifications for thickness tolerances. The overall height measures 2.13 inches (54 mm), and the outside diameter is 12.01 inches (305 mm), ensuring proper fitment and compatibility. The rotor is designed with five mounting bolt holes spaced on a 4.5 inch (114.3 mm) bolt circle diameter, matching the factory mounting pattern for the specified vehicles.

Compatible Vehicles and Applications

• Ford Explorer (various model years)
• Ford Explorer Sport Trac
• Mercury Mountaineer

This rotor is intended for use in conventional braking systems and does not include an ABS tone ring. It is a non-directional rotor, allowing installation on either side of the vehicle without concern for directional rotation.

Common Issues Addressed by This Rotor

• Brake pulsation or vibration due to warped rotors
• Reduced braking efficiency from worn or thin rotors
• Corrosion and rust buildup affecting rotor surface
• Overheating and brake fade during extended braking
• Noise and uneven brake pad wear caused by damaged rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the rotor thickness meets or exceeds the discard thickness specification of 1.12 inches (28.5 mm). Use proper torque specifications for mounting bolts to avoid rotor warping. Since this rotor is non-directional, it can be installed on either side of the vehicle. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.
