Detailed Product Description

The DuraGo BR34249 is a full cast, vented disc brake rotor specifically designed for BMW 745i and 745Li vehicles. Its cast iron construction provides the necessary durability and thermal conductivity to handle the heat generated during braking. The vented design allows air to flow between the rotor surfaces, helping to reduce brake fade and maintain consistent performance. This rotor features a drum-in-hat design, integrating the parking brake drum within the rotor hat, which is common for these BMW models. The non-directional brake surface allows for installation on either side of the vehicle without concern for rotor orientation.

Compatible Vehicles and Applications

This rotor is compatible with the following BMW models:

• BMW 745i
• BMW 745Li

It is intended for use as a direct replacement part to restore proper braking function and maintain vehicle safety.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear reducing braking efficiency
• Overheating and brake fade under heavy use
• Corrosion and surface damage affecting rotor performance
• Parking brake malfunction due to worn drum-in-hat rotor

Installation Notes and Tips

• Ensure the rotor thickness is above the discard thickness of 0.88 inches (22.4 mm) before installation
• Clean the rotor surface to remove any protective coating or debris prior to mounting
• Torque mounting bolts to manufacturer specifications using the 5-bolt pattern with 4.72 inch (120 mm) bolt circle diameter
• Check compatibility with ABS sensors as this rotor does not include an ABS tone ring
• Inspect brake pads and calipers during installation for optimal braking system performance
