Cheap Mercedes-Benz B-Class Brake

The Mercedes-Benz B-Class W246 generation ran from 2011 to 2018, with a facelift in 2014, so a 2012 and a 2016 car sit either side of that facelift boundary. Within the same generation the body and platform are shared, but brake disc and caliper sizes can change across a facelift refresh, so you should confirm with the breaker against your specific registration before ordering. Never assume a pre-facelift part will drop straight onto a post-facelift car without checking.

Yes — Mercedes moved to the W247 generation B-Class from 2019 onwards, replacing the W246 (2011–2018). These are distinct platforms with different running gear throughout, so brakes from a W247 will not cross over to a W246, and vice versa. Always quote your registration to the breaker so they can pull parts from the correct generation.

Engine size does influence brake specification on the B-Class, with higher-output petrol and diesel variants commonly fitted with larger front discs and uprated calipers compared to the entry-level engines. If you have a B200, B220, or a diesel like the B200d, confirm the exact disc diameter and caliper type with the breaker against your registration, as the breaker will need to match those figures rather than go on engine name alone. This is especially important if you are sourcing from a donor car with a different output than your own.

Trim level alone — SE, Sport, or AMG Line — does not change the fundamental brake fitment on the B-Class; colour, interior spec, and cosmetic packs make no difference to disc or caliper size. What actually drives brake specification is the engine variant and the generation, so focus on those when speaking to a breaker. Bear in mind that if a donor car carries a different trim's styling parts, such as different wheel sizes, the brakes behind them may still be the same as yours — but confirm with the breaker using your registration to be certain.

The W246 B-Class was facelifted in 2014, meaning a pre-facelift car (2011–2013) and your 2015 car sit on either side of that known boundary. The generation is the same, but whether the brake components interchange across the 2014 facelift is something you must confirm with the breaker against both registrations, as Mercedes can revise disc sizes and caliper fittings during a mid-life update. Do not assume compatibility purely because both cars carry the W246 name.

Yes — front and rear calipers are handed, meaning the nearside (NS, left) and offside (OS, right) are not interchangeable. When contacting a breaker, always specify which side you need alongside your registration, engine size, and whether your car is pre- or post-2014 facelift. Fitting the wrong-sided caliper is not possible without forcing it, so getting the side confirmed upfront saves time and return costs.
