Cheap BMW i7 Brake Discs

The BMW i7 does have conventional hydraulic brake discs on all four wheels — it is not a fully brake-by-wire vehicle. Like most modern EVs it uses regenerative braking to recover energy, but physical discs and calipers are still present and do wear out. Because the regenerative system does much of the braking work, the discs can suffer from corrosion if the car is used mainly on gentle runs, so replacement is a genuine and common requirement.

The i7 is part of BMW's G70 generation, which launched in the UK in 2023 as the first and so far only generation of this model. At the time of writing there is no prior generation and no confirmed facelift with altered running gear, so generation matching is straightforward — all UK i7s are G70. Always confirm the exact build date and any mid-cycle changes with the breaker against your registration, as brake specifications can be revised quietly during a production run.

These are different variants and are very likely to use different brake disc sizes — the M70 is a significantly more powerful and heavier car and BMW typically fits larger, uprated braking systems to match. When sourcing used discs, always quote your specific variant (xDrive60 or M70) to the breaker and ask them to verify part numbers against your registration. Do not assume discs from an M70 donor car will be a straight swap onto an xDrive60, or vice versa.

Trim level alone does not determine brake disc fitment on the i7 — it is the powertrain variant (xDrive60, M70 etc.) that governs which discs are fitted, not the interior or equipment pack. A Pure Excellence and an Excellence on the same drivetrain should share the same disc specification. That said, always confirm with the breaker against your registration, as optional sport brake packages could mean a car has larger discs regardless of its trim name.

The i7 shares its G70 platform with the combustion-engined 7 Series, and some braking components may be shared, but the i7's additional battery weight and regenerative braking calibration mean brake specifications are not necessarily identical across the range. This is a question you must route to the breaker, who can cross-reference part numbers against both donor and recipient registrations before you commit to buying. Never assume platform-sharing means part interchangeability without that check.

Because the i7 only went on sale in the UK from 2023, the pool of salvage cars reaching dismantlers is still relatively small, so availability of used discs will be more limited than for older 7 Series models. Findapart lets you request quotes from multiple UK breakers simultaneously, which gives you the best chance of locating the correct discs for your specific variant. Given the car's age, some breakers may also be able to source low-mileage discs from insurance write-offs, which can be good quality — always ask the breaker to confirm condition and mileage of the donor vehicle.
