Brembo Disc Brake Pad Set for Mercedes-Benz C-Class, E-Class, CLS, and GLC (2016–2023)

Made in Italy, the Brembo P50139 disc brake pad set replaces the factory pads on a broad range of Mercedes-Benz C-Class, E-Class, CLS, and GLC models. Coverage runs from the GLC300 and E300 through the C43 AMG, E53 AMG, CLS53 AMG, GLC63 AMG, and GLC63 AMG S, plus the GLC350e plug-in hybrid. Brembo develops its own friction compound for these pads and keeps testing, compound production, and mechanical processing in-house. The compound is designed to keep brake dust low, so wheels stay cleaner between washes.

Mercedes-Benz has used several part numbers for the pads this set replaces: A0004209000, A0004204900, and A0004204904. The A0004204900 and A0004204904 numbers also appear without the leading letter, as 0004204900 and 0004204904. If the old pads or your service records carry any of these numbers, this set is the Brembo equivalent. Because the same set spans standard models, hybrids, and AMG versions across four model lines, check your exact model and year in the fitment table rather than going by model family alone.

Every disc brake pad is a sacrificial part. Its friction material clamps against the rotor under pedal pressure and slowly wears away. Brembo has made brake components since 1964, starting with brake discs, and builds its pads under a quality system certified to ISO 9001 and IATF 16949.

Common Questions

How often should these pads be inspected?
Check pad thickness at oil changes or routine service against the minimum Mercedes-Benz specifies. Replace the pads before they wear out completely, because worn pads can damage the rotor.

What symptoms suggest the pads are due?
Pulsating, grinding, squeaking, rotor glazing, and rotor hot spots are common signs. Also watch for a noticeable lip on the rotor's outer edge.

Does one set cover both the AMG and non-AMG versions?
The fitment includes both, such as the GLC300 and the GLC63 AMG. Confirm your specific model in the table below.
