• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 0.94 inches (24 mm) with discard thickness at 0.88 inches (22.4 mm)
• Overall height of 2.88 inches (73.2 mm) and outside diameter of 12.99 inches (330 mm)
• Five mounting bolt holes with a 4.72 inch (120 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR901538 disc brake rotor is constructed from full cast iron, a material known for its strength and thermal conductivity, which helps maintain braking efficiency under demanding conditions. Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation and reducing the risk of brake fade during extended use. With a nominal thickness of 0.94 inches and a discard thickness of 0.88 inches, this rotor meets the precise specifications required for optimal braking performance on compatible BMW models.

Measuring 12.99 inches in diameter and 2.88 inches in overall height, the rotor fits securely with five mounting bolt holes arranged on a 4.72 inch bolt circle diameter. The non-directional brake surface simplifies installation, allowing the rotor to be mounted in either orientation without affecting performance. This conventional rotor does not include an ABS tone ring, so it is intended for vehicles equipped with compatible braking systems.

Compatible Vehicles and Applications

• BMW 228i
• BMW 328i and 328i xDrive
• BMW 330e
• BMW 428i, 428i Gran Coupe, 428i xDrive, and 428i xDrive Gran Coupe

This rotor is designed specifically for these BMW models, ensuring proper fitment and reliable braking performance when replacing worn or damaged rotors.

Common Issues Addressed by DuraGo BR901538

• Brake rotor warping causing vibration during braking
• Excessive brake fade from overheating
• Uneven rotor wear leading to reduced braking efficiency
• Corrosion and surface damage affecting rotor lifespan
• Noise and pulsation during brake application

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below discard thickness of 0.88 inches
• Ensure mounting surfaces are clean and free of debris for proper rotor seating
• Torque mounting bolts to manufacturer specifications to avoid rotor distortion
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Perform a brake system bleed if necessary after rotor replacement

Quality Assurance and Warranty

DuraGo disc brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function. While this product does not include a rust-resistant coating, the full cast iron construction provides durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
