Used Mercedes-Benz EQB Brake Caliper

The EQB does have conventional hydraulic brake calipers at all four wheels, so yes, this is a real part to source. Like most electric vehicles it uses regenerative braking heavily, which means the physical calipers tend to see less wear than on a combustion-engined car, but they are standard hydraulic units and do occasionally need replacing. You are looking for a used caliper in the normal way.

The EQB was launched in the UK in 2022 and is currently in its first generation, based on the GLB platform; there has been a mid-life refresh but the core generation has not changed. Year can still matter because the brake setup on the more powerful EQB 350 4MATIC (dual-motor) is larger than on the single-motor EQB 300 variants, so you need to match both the year and the motor/power variant, not just the model name. Always give the breaker your full registration to cross-reference.

The EQB received a facelift during its production run, and while running-gear components often carry over through such updates, whether calipers are identical across that boundary is not something to assume. Name the boundary to the breaker and ask them to verify against your registration before purchasing, as mid-generation brake specification changes are possible. Do not rely on visual similarity alone.

Trim level alone – AMG Line, Sport, or otherwise – does not change the brake caliper specification on the EQB; what matters is the drive variant (single-motor versus dual-motor 4MATIC) and the associated power output, because the larger twin-motor version carries bigger brakes to handle the extra performance. You may find a caliper from a different trim looks slightly different in finish or colour, but functionally the key variables are drivetrain and axle position (NS or OS), not trim badge. Confirm the drive variant matches yours when speaking to the breaker.

Yes, absolutely – front and rear calipers are completely different parts and are not interchangeable, so always specify which axle you need. On top of that, calipers are handed, meaning the nearside (NS, driver's side on a UK right-hand-drive car) and offside (OS, passenger side) are mirror images of each other, so tell the breaker exactly which corner you need. Getting both the axle and the side wrong means the part will not fit.

The EQB shares its platform with the GLB, and there is a reasonable chance that some brake components overlap, particularly on comparable power variants. However, the EQB's additional weight from its battery pack may mean different brake specifications were fitted even where the two models look mechanically similar. This is exactly the kind of cross-model interchange question to put directly to an experienced breaker, quoting your EQB's registration, rather than to assume compatibility.
