Technical Details and Construction

The DuraGo BR900726 rotor is made from cast iron, a material known for its excellent thermal conductivity and wear resistance. This rotor features a vented design that allows air to flow between the rotor faces, helping to dissipate heat more effectively during braking. The drum-in-hat construction integrates a parking brake drum, making it suitable for vehicles equipped with rear drum parking brakes. The rotor's non-directional surface allows for flexible installation without concern for rotation direction. With five mounting bolt holes spaced on a 120 mm circle, this rotor fits securely on BMW 135i and 135is models.

Compatible Vehicles and Applications

• Designed specifically for BMW 135i and 135is models
• Ideal replacement for worn or damaged rear disc brake rotors with integrated parking brake drums
• Addresses issues such as brake rotor warping, uneven wear, and reduced braking efficiency
• Suitable for vehicles experiencing brake noise or vibration due to rotor surface irregularities

Installation Notes and Tips

When installing the DuraGo BR900726 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper fitment. Verify the rotor thickness before installation; replace if below the discard thickness of 20.4 mm. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle's ABS system. Use proper torque specifications for the five mounting bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance and Warranty

DuraGo manufactures the BR900726 rotor to meet or exceed OEM specifications for fit, form, and function. The full cast iron construction and vented design contribute to consistent braking performance and durability.
