Detailed Product Description

The DuraGo BR54105 disc brake rotor is engineered with a full cast iron construction, providing the necessary durability and thermal conductivity required for consistent braking performance. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. This reduces the risk of brake fade and extends the rotor's service life. The rotor features a drum-in-hat design, integrating a parking brake drum within the rotor assembly, which is compatible with the rear braking system of select Ford and Mercury vehicles.

With an outside diameter of 11.61 inches and a mounting bolt hole pattern of 5 holes spaced on a 4.5 inch bolt circle, the BR54105 ensures a precise fit for the Ford Crown Victoria, Mercury Grand Marquis, and Marauder models. The nominal thickness of 0.75 inches and discard thickness of 0.71 inches provide clear guidelines for maintenance and replacement intervals.
