• Vented rotor design to improve cooling
• Drum-in-hat construction for integrated parking brake compatibility
• Non-directional brake surface for versatile installation
• Five mounting bolt holes with precise fitment dimensions
• Compatible with BMW 330i, 330xi, 335d, 335i, 335is, 335i xDrive, 335xi, and X1 models

Detailed Product Features and Specifications

The BR900604 rotor features a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.8 inches (20.4 mm), ensuring a clear service life indicator for maintenance. Its overall height measures 2.64 inches (67 mm), and the outside diameter is 13.23 inches (336 mm), matching OEM specifications for proper fitment. The rotor includes five mounting bolt holes arranged on a 4.72-inch (120 mm) bolt circle diameter, with each hole measuring 0.57 inches (14.6 mm) in diameter. The center hole diameter is 2.95 inches (75 mm), allowing for precise hub alignment. This rotor does not include an ABS tone ring and is not cross-drilled or slotted, maintaining a solid braking surface optimized for everyday driving conditions.

Compatible BMW Models and Applications

This DuraGo disc brake rotor is compatible with a range of BMW vehicles, including the 330i, 330xi, 335d, 335i, 335is, 335i xDrive, 335xi, and X1. It is designed to replace original equipment rotors on these models, providing a direct fit and maintaining factory braking performance. The drum-in-hat design integrates the parking brake drum, making it suitable for vehicles equipped with drum parking brakes.

Common Issues Addressed by BR900604 Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced braking efficiency
• Overheating due to insufficient rotor ventilation
• Corrosion and surface damage affecting brake pad contact
• Noise or pulsation from uneven rotor surfaces

Installation Notes and Tips

When installing the DuraGo BR900604 rotor, ensure the mounting surface is clean and free of debris to prevent misalignment. Use proper torque specifications for the five mounting bolts to avoid rotor distortion. Since this rotor is non-directional, it can be installed on either side of the vehicle. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Verify rotor thickness before installation to confirm it meets minimum discard thickness requirements.
