Detailed Product Description

The DuraGo BR900876-01 disc brake rotor is constructed from high-quality cast iron, providing excellent thermal conductivity and durability under demanding braking conditions. Its full cast, solid design incorporates a drum-in-hat type rotor, which integrates the parking brake drum into the rotor assembly, making it compatible with the rear braking system of Mercedes-Benz ML and R-Class models. The rotor features a rust-resistant coating to reduce corrosion, helping maintain performance and appearance over time.

With an outside diameter of 12.99 inches (330 mm) and an overall height of 2.47 inches (62.8 mm), this rotor fits vehicles requiring a 5-bolt mounting pattern with a 4.41 inch (112 mm) bolt circle diameter. The nominal thickness of 0.55 inches (14 mm) ensures structural integrity, while the discard thickness of 0.45 inches (11.4 mm) indicates when replacement is necessary to maintain safe braking performance. The non-directional brake surface allows for flexible installation without concern for rotor orientation.
