Technical Details and Specifications

The DuraGo BR34146 rotor features a solid, full cast design without cross-drilling or slotting, providing a stable braking surface ideal for everyday driving conditions. With a nominal thickness of 0.5 inches (12.6 mm) and a discard thickness of 0.46 inches (11.7 mm), this rotor maintains structural integrity throughout its service life. The overall height measures 2.47 inches (62.8 mm), and the center hole diameter is 2.76 inches (70.1 mm), ensuring precise fitment on compatible Land Rover models. This rotor does not include an ABS tone ring and is coated without rust-resistant treatment, so regular inspection and maintenance are recommended to prevent corrosion.

Compatible Land Rover Models

This disc brake rotor is specifically designed for use with Land Rover Discovery and Range Rover vehicles. The part number BR34146 ensures compatibility with these models, providing a direct replacement for worn or damaged rotors. Using the correct rotor helps maintain braking efficiency and vehicle safety.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking performance due to worn rotor thickness
• Uneven brake pad wear from damaged rotor surfaces
• Noise and vibration during braking
• Overheating and brake fade under normal driving conditions

Installation Notes and Tips

When installing the DuraGo BR34146 rotor, ensure the mounting surface is clean and free of debris. Verify the rotor thickness before installation to confirm it meets minimum specifications. Since this rotor lacks a rust-resistant coating, applying an anti-corrosion treatment to the rotor hat and hub area can extend service life. Use proper torque specifications on the 5 mounting bolts to avoid rotor distortion. This rotor is non-directional, allowing installation on either side of the vehicle without concern for rotation direction.
