Durable Construction and Precise Specifications

The BR900660 rotor features a full cast iron construction, providing the necessary strength to withstand the rigors of commercial and fleet use. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and maintain consistent stopping power. With an overall height of 146.2 mm (5.76 inches) and a center hole diameter of 123.2 mm (4.85 inches), this rotor is engineered for a precise fit. The drum-in-hat design integrates a drum brake surface within the rotor, supporting parking brake functionality common in these vehicle models.
