Product Details

Zimmermann brake rotors are manufactured to dimensions and material quality specified by automotive manufacturers, making this rotor a direct-fit replacement for select Mercedes-Benz front brake applications. The perforated design supports heat dissipation under repeated braking, while the coated finish helps maintain a cleaner appearance and resists surface corrosion. This part number, 400.3625.20, is also referenced in aftermarket catalogs for the same application.

Compatible fitment includes 2016 Mercedes-Benz SLK55 AMG, front; 2012-2015 Mercedes-Benz SLK55 AMG, front; 2011-2014 Mercedes-Benz CL550, front; 2012-2013 Mercedes-Benz S550, front; 2012 Mercedes-Benz S550, front without Sport Package; 2004-2012 Mercedes-Benz SL600, front; 2005-2011 Mercedes-Benz SL65 AMG, front; 2003-2008 Mercedes-Benz SL55 AMG, front; 2006 Mercedes-Benz CLS55 AMG, front; and 2003-2006 Mercedes-Benz E55 AMG, front.

Common Reasons for Replacement

• Brake pulsation or vibration during stopping
• Rotor scoring, grooves, or uneven wear
• Corrosion on the braking surface or hat area
• Reduced braking consistency under repeated heat cycles
• Rotor thickness approaching minimum specification

Installation Notes

Verify rotor diameter, thickness, hub bore, and bolt pattern before installation. This rotor is for front axle applications only and must be matched to the vehicle’s brake package, including any model-specific exclusions noted in fitment. Inspect pads, calipers, and wheel hub condition during service to confirm proper rotor seating and braking performance.

Quality Assurance

Zimmermann standard rotors are produced as equivalent-quality replacement parts aligned with original equipment dimensions and material requirements. The coated finish and high-carbon construction reflect Zimmermann’s focus on OE-style brake rotor specifications for Mercedes-Benz applications.
