Detailed Product Description

The DuraGo BR34489 is a full cast iron disc brake rotor designed specifically for select Land Rover models such as the Defender 90, Defender 110, Defender 130, Discovery, Range Rover, and Range Rover Sport. Its vented construction enhances heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The rotor measures 14.96 inches (380 mm) in outside diameter and has a nominal thickness of 1.34 inches (34 mm), with a discard thickness of 1.22 inches (31 mm), ensuring it meets OEM specifications for safe and effective braking. The rotor features five mounting bolt holes with a 4.72 inch (120 mm) bolt circle diameter and 0.59 inch (15 mm) hole diameter, compatible with the specified Land Rover models. This conventional, non-directional rotor does not include an ABS tone ring and is designed for straightforward installation and reliable performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving noise or vibration issues related to rotor surface wear
• Upgrading to a vented rotor for improved heat management in off-road or heavy-duty use
• Ensuring proper fitment and compatibility with Land Rover Defender and Range Rover brake systems

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface to remove any protective coatings or contaminants prior to mounting
• Use proper torque specifications for mounting bolts to avoid rotor warping
• Inspect brake pads and calipers during installation for optimal braking system performance
• Ensure compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
