Detailed Product Description

The DuraGo BR34175 disc brake rotor is a solid, full cast iron rotor designed to meet the braking demands of Mercedes-Benz ML55 AMG, ML430, and ML500 vehicles. Its drum-in-hat construction integrates a drum brake surface within the rotor hat, allowing for rear parking brake functionality. The rotor features a non-directional braking surface, which simplifies installation by allowing it to be mounted in either orientation without affecting performance.

With an outside diameter of 13.05 inches and a nominal thickness of 0.55 inches, this rotor provides a robust braking surface. The discard thickness of 0.48 inches indicates the minimum safe thickness before replacement is necessary, helping maintain optimal braking efficiency and safety. The rotor includes five mounting bolt holes arranged on a 4.41-inch (112 mm) bolt circle diameter, compatible with the specified Mercedes-Benz models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores braking performance on Mercedes-Benz ML55 AMG, ML430, and ML500 rear axles
• Addresses rotor thickness below manufacturer specifications
• Eliminates uneven brake pad wear due to rotor surface irregularities
• Supports proper function of rear drum-in-hat parking brake systems

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with ABS sensors as this rotor does not include an ABS tone ring
• Inspect brake pads and hardware during rotor replacement for optimal system performance
