Technical Specifications and Design Features

The BR900972 rotor features a full cast iron construction that provides strength and resistance to wear. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to prevent brake fade. The cross-drilled holes further aid in heat dissipation and help maintain consistent braking performance. This rotor is a drum-in-hat type, integrating the drum brake surface within the rotor assembly, and includes five mounting bolt holes with a bolt circle diameter of 120.65 mm (4.75 inches). The rotor’s outside diameter measures 12.99 inches (330 mm), with a nominal thickness of 1.02 inches (26 mm) and an overall height of 1.93 inches (49.1 mm). The center hole diameter is 2.78 inches (70.7 mm), ensuring proper fitment on specified vehicles.

Installation Notes and Tips

When installing the DuraGo BR900972 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper seating. Verify the rotor thickness before installation; the discard thickness is 0.94 inches (24 mm), and the nominal thickness is 1.02 inches (26 mm). Use proper torque specifications for the five mounting bolts to avoid rotor warping. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system.
