Detailed Product Description

The DuraGo BR54143 is a full cast, vented disc brake rotor designed specifically for select Ford and Mercury vehicles, including the Explorer, Explorer Sport Trac, and Mountaineer. Its cast iron construction provides a balance of strength and heat dissipation, essential for maintaining braking efficiency during extended use. The vented design allows air to flow between the rotor surfaces, reducing heat buildup and minimizing the risk of brake fade. With a nominal thickness of 1.18 inches and a discard thickness of 1.12 inches, this rotor meets OEM specifications for safe replacement intervals.

The rotor features a 12.01-inch outside diameter and an overall height of 2.13 inches, ensuring proper fitment and compatibility with the specified vehicle models. It includes five mounting bolt holes arranged on a 4.5-inch bolt circle diameter, matching factory mounting points. The non-directional brake surface allows for installation on either side of the vehicle 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 Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking performance due to rotor thickness below discard limits
• Eliminating noise and vibration from uneven rotor surfaces
• Restoring proper rotor dimensions for safe brake pad contact
• Upgrading to vented rotors for improved heat dissipation in daily driving

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness of 1.12 inches
• Clean mounting surfaces to prevent rotor runout and ensure proper fit
• Use proper torque specifications on mounting bolts to avoid rotor distortion
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Check for compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
