Product Description

The Brembo 09.5373.20 is a vented front brake rotor from the Brembo Prime line, designed for the Mercedes-Benz R129 SL-Class (300SL, 500SL, SL320, SL500) and W124 E-Class (500E, E500) models equipped with the standard 300mm front brake configuration. It cross-references Mercedes-Benz OE part numbers A1294212012 and 1294210612, and installs as a direct bolt-on with no modifications required. Both front rotors are included per box.

This part carries the Brembo ".20" suffix, indicating a standard (non-UV) coated finish - the protective treatment on non-braking surfaces provides corrosion resistance during storage and initial service without the full UV paint process of the ".11" series. High-carbon cast iron alloy reduces the noise and vibration typical of economy-grade replacements. ECE-R90 certified. Important: the 300mm front rotor applies only to R129 and W124 vehicles with the standard brake setup. Some 500E/E500 vehicles above chassis serial B930494, later SL500 models, and any R129 equipped with enlarged front brakes will require a different part - confirm your vehicle's front rotor diameter before ordering.
