BMW X4 Brake Caliper Replacement Parts

No – the F26 first-generation X4 (2014–2018) and the G02 second-generation X4 (2018–onwards) are entirely different platforms, so the calipers are not interchangeable. Always quote your registration to the breaker and confirm the generation before ordering.

Engine size and power output do affect brake specification on the X4 – larger, more powerful variants such as the xDrive30d and M40i are likely to carry bigger brakes than the entry-level xDrive20d. Check your exact engine code with the breaker against the donor vehicle to make sure the caliper, disc size, and bolt pattern all match your car.

Trim level alone does not determine brake caliper fitment on the X4 – what matters is the generation and engine variant, not whether the car is badged xLine, M Sport, or another trim. Bear in mind that M Sport and M40i models can come with larger or upgraded brakes, so confirm the exact brake specification against your registration with the breaker rather than relying on trim name alone.

All three years fall within the G02 second-generation X4 (2018–onwards), so in principle calipers from the same engine variant should correspond, but mid-generation brake specification changes are possible and cannot be ruled out. Confirm the donor vehicle's registration and engine code with the breaker before purchasing to make sure the caliper is a genuine match.

Yes – brake calipers are handed, so you must tell the breaker whether you need the nearside (passenger side, left) or offside (driver side, right) caliper, as well as whether it is front or rear. Getting this wrong means the bleed nipple and piston orientation will be incorrect, so double-check before placing your order.

The F26 X4 is based on the F25 X3 platform, and the G02 X4 shares its underpinnings with the G01 X3, so there is a reasonable chance of overlap, but brake specifications can differ between the two models depending on engine variant and any upgrades applied. This is exactly the kind of cross-model interchange question to put directly to the breaker with both vehicles' registrations, rather than assume compatibility.
