Cheap Mercedes-Benz GLB Brake Discs

The Mercedes-Benz GLB has been a single generation (X247) running from 2019 onwards, with a facelift arriving around 2023, so a 2020 disc and a 2023 disc are from the same platform — however, whether the facelift brought any brake spec changes is something you should confirm with the breaker against your exact registration before buying.

Yes, engine size does affect brake disc sizing on the GLB — larger and more powerful variants such as the GLB 250 and AMG Line 4Matic models typically run bigger discs than the entry-level GLB 180 or 200 petrol and diesel engines, so always tell the breaker your exact engine when asking for a quote.

Trim level alone does not determine brake disc fitment on the GLB — it is engine size and drivetrain (front-wheel drive versus 4Matic all-wheel drive) that matter, not whether the car is badged Progressive, Sport, or AMG Line; that said, AMG Line models are more commonly paired with larger engines, so cross-check both trim and engine with the breaker to be sure.

Yes, front and rear brake discs are different parts with different diameters and hat depths, so always state which axle you need when contacting a breaker — if you are unsure which disc has failed, a good independent garage can confirm this before you order.

The 200d and 220d are different engine variants and may run different brake specifications, so you should not assume the discs are interchangeable — give the breaker both the engine code and your registration number so they can check the exact spec of the donor vehicle against yours.

Yes, all variants of the GLB (X247, 2019 onwards) are fitted with brake discs on both the front and rear axles as standard — this applies across the full engine range including petrol, diesel, and plug-in hybrid variants, so sourcing used discs from a breaker is a straightforward and sensible option.
