Cheap Mercedes-Benz EQB Brake Discs

Yes, brake discs do exist on the EQB despite it being a battery-electric vehicle. Like most EVs, the EQB uses conventional hydraulic disc brakes at all four corners alongside its regenerative braking system, so worn or damaged discs still need replacing in the usual way. Regenerative braking does mean the discs are used less aggressively than on a petrol or diesel car, but they are a real serviceable part you can source from a breaker.

The EQB (X243) launched in the UK in 2022 and, as of 2024, there is only one generation with no major facelift that has taken place yet, so the year range is relatively straightforward. That said, brake disc size can vary depending on which powertrain variant you have – the EQB 250 (front-wheel drive) and the EQB 300 4MATIC or EQB 350 4MATIC (all-wheel drive) may carry different disc specifications front and rear. Always confirm the exact part against your registration with the breaker before purchasing.

This is unlikely to be a straight swap, as larger, more powerful variants like the EQB 350 4MATIC typically carry larger or heavier-duty brake discs to cope with the extra weight and performance compared with the EQB 250. The front-wheel-drive EQB 250 also has no rear drive unit, which can affect rear brake sizing. Confirm the exact disc diameter and specification against both registrations with the breaker before agreeing a sale.

Trim level alone does not determine brake disc fitment on the EQB – what matters is the powertrain variant (e.g. EQB 250, EQB 300 4MATIC, EQB 350 4MATIC) rather than whether the car is dressed in AMG Line or Progressive specification. You may find AMG Line models have a sportier visual appearance including different wheel sizes, and if wheel size differs, disc diameter can sometimes differ too, so it is worth confirming this detail with the breaker against your registration. In short, don't rule out a disc from a differently trimmed car, but do verify the specification matches yours.

Because the EQB has not undergone a facelift or generation change within the 2022–2024 UK production window, discs from across that period are more likely to be compatible than on a model that has crossed a major revision boundary – but mid-generation running changes and sport suspension differences can sometimes affect brake specification in ways that aren't obvious from the outside. Confirm the exact disc diameter, bolt pattern, and any sport-pack variants with the breaker against your specific registration to be certain. Never assume fitment purely on the basis of year alone.

For front and rear axle discs, a single disc is the same on both the nearside (NS) and offside (OS) of the same axle on most passenger cars including the EQB, so left-right side generally does not matter for the disc itself. What does matter is whether you need a front or rear disc, as these are different parts with different diameters and thicknesses. Let the breaker know whether you need front or rear, and confirm the powertrain variant, and they should be able to match the correct part to your car.
