Detailed Product Description

The DuraGo BR34145 disc brake rotor is engineered for Mercedes-Benz ML320, ML350, and ML430 vehicles requiring a solid rotor with a drum-in-hat design. Made from cast iron, this rotor provides consistent thermal conductivity and durability under normal driving conditions. The solid rotor design without cross drilling or slots ensures even pad wear and reduces the risk of cracking under stress. Its non-directional braking surface allows for flexible installation without concern for rotor orientation.

The drum-in-hat construction integrates the parking brake drum within the rotor, maintaining factory-style parking brake performance. With a 5-bolt mounting pattern and precise dimensions including an 11.22 inch outside diameter and 2.64 inch center hole diameter, this rotor matches OEM specifications for a direct replacement on compatible Mercedes-Benz ML models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores proper braking performance on Mercedes-Benz ML320, ML350, and ML430
• Addresses rotor thickness below discard limits (0.51 inches / 13 mm)
• Eliminates uneven pad wear due to rotor surface imperfections
• Supports parking brake function with integrated drum-in-hat design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surface to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with vehicle ABS system; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to optimize braking performance
