Detailed Description

SP32114 is a front brake rotor for Mercedes-Benz ML500, ML55 AMG, and ML430 applications. It is a vented rotor with a coated surface that helps resist rust on exposed areas, making it a practical choice for drivers replacing worn front brake rotors on Mercedes-Benz ML500 front brake systems, Mercedes-Benz ML55 AMG front brake systems, and Mercedes-Benz ML430 front brake systems. This part cross-references Bosch 36010943 for the same application.

What This Rotor Helps Address

• Brake pulsation caused by rotor wear or uneven braking surfaces
• Reduced braking performance from a worn front disc rotor
• Surface corrosion on exposed rotor areas
• Noise related to rotor finish deterioration
• Service replacement for OE-style front brake maintenance

Installation Notes and Tips

Verify rotor diameter, thickness, and bolt pattern before installation. Clean the rotor friction surfaces before mounting, and inspect pads, calipers, and hub condition at the same time to help ensure even contact. This rotor is listed for front position use on 2000-2001 Mercedes-Benz ML430, 2000-2003 Mercedes-Benz ML55 AMG, and 2002-2005 Mercedes-Benz ML500.

Quality Assurance

ATE brake parts are backed by Continental Automotive Systems’ original equipment brake engineering experience and are produced to a higher standard than conventional replacement parts. The coated brake disc design reflects ATE’s focus on premium materials, corrosion protection, and OE-level manufacturing consistency.
