Mercedes-Benz X-Class Brake Discs Replacement Parts

Yes, brake discs are a genuine part on the Mercedes-Benz X-Class, which was sold in the UK from 2017 to 2020 as a single generation with no facelift — so any used discs pulled from another X-Class of that period are worth considering, subject to the engine size check below. The X-Class shared its underpinnings with the Nissan Navara, and disc sizing varied between the smaller 2.3-litre diesel and the larger 3.0-litre V6 diesel, so confirm the engine size matches your own before buying. Always confirm fitment with the breaker against your exact registration.

Almost certainly not — larger, more powerful engines typically run bigger brake discs, and the 3.0-litre V6 X-Class is a heavier, more potent vehicle than the 2.3-litre variants. You should treat these as different fitment groups and tell the breaker your exact engine size when requesting a quote. Never assume discs from a 2.3 will swap onto a V6 car.

No, trim level does not affect brake disc fitment on the X-Class — Progressive, Power, and Stylish are equipment and cosmetic grades rather than mechanical ones. What matters is your engine size (2.3 or 3.0 V6) and whether you are sourcing the front or rear disc. Mention your trim to the breaker if it helps them identify the vehicle, but the disc specification is driven by the drivetrain, not the trim name.

No — front and rear brake discs are different sizes and are not interchangeable; front discs are larger as they handle the majority of braking force. When contacting a breaker, always specify whether you need the nearside (NS) or offside (OS) disc, and state front or rear clearly. Mixing front and rear discs would be unsafe and the parts will not fit correctly.

The X-Class had a short production run, from 2017 to 2020, which means fewer donor vehicles in the dismantler network compared to longer-lived models. However, because the X-Class shares its platform with the Nissan Navara, it is worth asking your breaker whether Navara-sourced discs are dimensionally compatible with your variant — but do not assume they are without the breaker confirming this against your registration. Using Findapart to get quotes from multiple breakers gives you the best chance of locating the right used disc.

It is possible that individual vehicles left the factory or were modified with uprated braking components, and this could mean the disc diameter or fitment differs from a standard example. This is not something that can be confirmed from the model name alone — you should check with the breaker and provide your full registration so they can verify the exact specification of your vehicle. Do not assume a standard-spec disc will fit without that confirmation if you have any reason to think your car has non-standard running gear.
