Detailed Product Description
The DuraGo BR900776 rotor is constructed from full cast iron, providing a balance of strength and heat dissipation essential for effective braking. Its vented design helps reduce heat buildup during braking, which can improve rotor longevity and maintain consistent brake performance. The drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with vehicles equipped with rear drum parking brakes. This rotor is non-directional, allowing for flexible installation without concern for rotation direction. The absence of cross drilling and slots means it is designed for standard braking applications rather than high-performance or track use.
Compatible Vehicles and Applications
This rotor is compatible with BMW 125i and 128i models, ensuring a precise fit and proper function. It is ideal for drivers seeking a reliable replacement rotor that meets OEM specifications for these vehicles.
- Restores braking efficiency on BMW 125i and 128i
- Replaces worn or warped rotors causing vibration or noise
- Addresses rotor thickness below discard limits (0.72 inches)
- Eliminates brake pulsation and uneven pad wear
- Supports proper parking brake operation with drum-in-hat design
Installation Notes and Tips
When installing the DuraGo BR900776 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper seating. Verify the rotor thickness is within nominal specifications (0.79 inches) before installation. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. Use the correct torque specifications for the 5 mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
