Detailed Product Description

The DuraGo BR34100 disc brake rotor is constructed from cast iron, a material known for its excellent thermal conductivity and resistance to warping under high temperatures. This rotor features a solid design with a drum-in-hat configuration, which integrates the parking brake drum into the rotor hat, making it compatible with vehicles equipped with drum-in-hat parking brakes. The rotor’s nominal thickness of 0.39 inches (10 mm) ensures sufficient material for effective braking, while the discard thickness of 0.33 inches (8.3 mm) indicates when replacement is necessary to maintain safety and performance.

With an outside diameter of 11.42 inches (290 mm) and a 5-bolt mounting pattern, this rotor fits securely on the specified Mercedes-Benz models. The non-directional brake surface allows for flexible installation without concern for rotor orientation. Note that this rotor does not include an ABS tone ring and does not feature cross-drilled or slotted surfaces, which aligns with the original equipment specifications for these vehicles.

Compatible Vehicles and Applications

• Mercedes-Benz C36 AMG, C230, C240, C280, C320, C350
• Mercedes-Benz CLK320, CLK350, CLK430
• Mercedes-Benz E300, E320, E420, E430
• Mercedes-Benz SLK280, SLK300, SLK350
