Detailed Product Description

The DuraGo BR901544 rotor is a vented disc brake rotor designed to provide consistent braking performance under normal driving conditions. Its composite construction combines a cast iron braking surface, known for its wear resistance and heat tolerance, with a lightweight aluminum hat to reduce unsprung weight. This rotor features a nominal thickness of 1.18 inches (30 mm) and a discard thickness of 1.12 inches (28.4 mm), ensuring it meets OEM specifications for safe operation. The 13.7 inch (348 mm) outside diameter and five mounting bolt holes with a 4.72 inch (120 mm) bolt circle diameter make it compatible with various BMW models including the 535d, 535i, 640i, and ActiveHybrid 5 variants.

Compatible Vehicles and Applications

• BMW 535d and 535d xDrive
• BMW 535i and 535i xDrive
• BMW 640i, 640i Gran Coupe, 640i xDrive, and 640i xDrive Gran Coupe
• BMW ActiveHybrid 5

This rotor is intended for use in front or rear disc brake systems where a vented, conventional rotor is specified. It is not equipped with an ABS tone ring and does not feature cross-drilled or slotted surfaces, making it suitable for drivers seeking a direct replacement rotor that meets factory standards.

Common Issues Addressed by DuraGo BR901544

• Brake rotor warping due to heat buildup
• Uneven brake pad wear caused by rotor thickness variation
• Brake noise and vibration from worn or damaged rotors
• Reduced braking efficiency from rotor surface damage
• Corrosion-related rotor degradation (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.12 inches) before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal braking performance

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, its composite construction supports durability under typical driving conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
