Detailed Product Description

The DuraGo BR901056 disc brake rotor is constructed from full cast iron, a material known for its durability and effective heat management during braking. This rotor features a vented design, which allows air to flow between the rotor surfaces, helping to dissipate heat and maintain consistent braking performance under demanding conditions. With a nominal thickness of 0.79 inches and a discard thickness of 0.72 inches, this rotor ensures a balance between longevity and safety, signaling when replacement is necessary to maintain optimal braking efficiency.

Measuring 11.81 inches in outside diameter, the rotor fits precisely on BMW Z4 models requiring a 5-bolt mounting pattern with a 4.72-inch bolt circle diameter. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This conventional rotor does not include an ABS tone ring, so it is compatible with vehicles that do not require this feature.

Compatible Applications and Common Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores braking performance affected by rotor thickness below discard limits
• Addresses overheating issues by improving heat dissipation with vented design
• Suitable for BMW Z4 models requiring 300 mm diameter rotors with 5 mounting bolts
• Helps eliminate uneven brake pad wear due to rotor surface irregularities

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surface 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 rotor performance
