Used Mercedes-Benz CLA Brake Caliper

The CLA comes in two generations: the first-generation (C117) ran from 2013 to 2019, and the second-generation (C118) launched in 2019 onwards. The two generations are entirely different platforms, so calipers do not cross between them. Even within each generation there are brake size differences depending on engine variant, so always confirm the exact part against your registration with the breaker.

Engine size genuinely matters for brake caliper fitment on the CLA — the larger, more powerful 250 variants were often fitted with bigger brake assemblies than the entry-level 200. You should not assume a caliper from a 200 will fit a 250 even if both cars are from the same generation. Give the breaker both registrations so they can verify the caliper dimensions match.

Trim level alone — Sport, AMG Line, Executive, or similar — does not change the brake caliper specification on the CLA; what matters is the engine size and generation. A caliper from an AMG Line car and a Sport car with the same engine and from the same generation should be mechanically identical, though any painted or styled caliper covers are cosmetic and may look different. Confirm the engine code and year with the breaker to get the right part.

This is an important boundary to check: the first-generation C117 CLA ran until 2019, when the second-generation C118 was introduced, and the two share no caliper compatibility. A 2018 car is first-generation, but a 2019 car could be either generation depending on when it was registered, so you cannot assume compatibility based on year alone. Ask the breaker to match the part to your registration rather than just the model year.

The CLA Shooting Brake (estate body) shares its platform and running gear with the equivalent saloon-bodied CLA of the same generation, and the brake caliper specification is determined by engine size rather than body style. A Shooting Brake and a saloon with the same engine from the same generation should use the same calipers, but confirm with the breaker against both registrations to be sure.

Yes — brake calipers are side-specific, so you must specify whether you need the nearside (NS, left as you sit in the car) or the offside (OS, right as you sit in the car). Getting the wrong side is a very common mistake, and a breaker will always need this information before they can quote correctly. Double-check which corner of the car the faulty caliper is on before you contact them.
