Second Hand Mercedes-Benz B-Class Brake Pedal

The W245 and W246 are completely different generations with different pedal boxes and bulkhead layouts, so a pedal from the first generation is very unlikely to interchange with the second. Always quote your registration to the breaker so they can match the correct generation. Never assume fitment across this generational boundary.

The W246 ran from 2012 to 2018 and received a facelift in 2015, but the pedal box and brake pedal assembly are generally shared across the pre- and post-facelift cars within this generation. That said, whether a specific used pedal crosses that 2015 facelift boundary cleanly is worth confirming with the breaker against your registration, as minor running-gear revisions can occasionally affect fitment. Do not assume without checking.

The brake pedal itself is part of the pedal box assembly and is primarily generation-specific rather than engine-specific on the B-Class, since it is a front-wheel-drive family hatchback throughout both the W245 and W246 generations. However, because larger engines can be paired with uprated braking systems, it is worth confirming with the breaker that the pedal from their donor vehicle matches your engine variant, particularly if you have a higher-output model such as the B 220. Always give the breaker your full registration to be certain.

Trim level does not affect brake pedal fitment on the B-Class - the pedal assembly is the same across SE, Sport, and AMG Line grades within the same generation. Trim differences on these cars relate to interior finish, wheels, and cosmetic equipment rather than the pedal box. Source from the correct generation and you can disregard trim when searching.

Yes, the B-Class in both W245 (2005-2011) and W246 (2012-2018) forms has a conventional mechanical brake pedal assembly, so the part genuinely exists and is available from breakers. Later W247 B-Class models (2019 onwards) also retain a physical brake pedal. You are looking for the correct pedal box or brake pedal arm for your generation, which a breaker can identify from your registration.

In principle, the W246 generation (2012-2018) shares a common pedal box design, so parts from within that generation are likely to be compatible, but the 2015 facelift is a boundary worth flagging to your breaker before buying. Confirm the donor vehicle's year and your registration with the breaker so they can verify the part matches before it leaves the yard. Never rely solely on generation alone without that check.
