Detailed Product Description

The DuraGo BR34228 rotor is constructed from full cast iron, providing a balance of strength and thermal conductivity essential for braking components. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent performance. The drum-in-hat configuration integrates a parking brake drum within the rotor, making it compatible with vehicles equipped with drum parking brakes, such as the BMW 320i, 323Ci, and 323i models.

This rotor features a non-directional braking surface, which means it can be installed on either side of the vehicle without affecting performance. The absence of cross drilling and slots reduces the risk of cracking under stress, contributing to the rotor's durability. The precise mounting bolt hole pattern and center hole diameter ensure a secure fit on compatible BMW vehicles.

Compatible Vehicles and Applications

• BMW 320i (various model years)
• BMW 323Ci
• BMW 323i

This rotor is designed to replace worn or damaged rotors on these BMW models, restoring braking efficiency and safety.

Common Issues Addressed by DuraGo BR34228

• Brake pulsation caused by warped rotors
• Reduced braking performance due to worn rotor thickness
• Excessive brake noise from uneven rotor surfaces
• Overheating and brake fade during extended use
• Incompatibility with drum-in-hat parking brake systems

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.69 inches) before installation
• Clean mounting surfaces to prevent rotor runout
• Torque mounting bolts to manufacturer specifications
• Check compatibility with vehicle ABS system; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
