Second Hand BMW i7 Brake Caliper

Yes, the BMW i7 does have conventional hydraulic brake calipers — despite being a fully electric vehicle, it uses a traditional friction braking system alongside its regenerative braking, so calipers, discs, and pads are all present on the car. The regenerative system does most of the work at lower speeds, which means the physical calipers often see less wear than on a comparable petrol or diesel car, so used calipers from a dismantled i7 can be in good condition. Always confirm with the breaker that the caliper they have is from an i7 rather than another 7 Series variant, as the xDrive all-wheel-drive system on some i7s may affect front caliper specification.

The BMW i7 (G70) was launched in the UK from 2022 onwards as a single generation, so a 2023 and a 2024 car sit within the same generation and the calipers are likely compatible in principle. However, BMW did introduce updates to the i7 during its early production run, and whether any brake hardware changed mid-generation is something you should confirm with the breaker against your specific registration number. Never assume fitment without that check.

Engine size and drivetrain layout matter here rather than trim name alone — the higher-output xDrive60 and M70 xDrive variants are significantly more powerful and heavier than the eDrive50, and BMW typically fits larger or differently specified brake assemblies to cope with that extra performance and weight. The trim name itself (such as the standard i7 versus M Sport specification) does not affect caliper fitment in terms of cosmetic differences, but the underlying drivetrain variant very much does. Always tell the breaker your exact model designation — eDrive50, xDrive60, or M70 xDrive — so they can match the correct caliper, and confirm fitment against your registration.

Yes, this matters — brake calipers are handed, meaning the nearside (left, passenger side in the UK) and offside (right, driver side) calipers are mirror images of each other and are not interchangeable. When contacting a breaker, always specify which corner you need: nearside front, offside front, nearside rear, or offside rear. Getting this wrong means the part will not fit, so be clear from the outset.

The i7 shares the G70 platform with the internal combustion and plug-in hybrid 7 Series models, so some braking components may be shared, but the i7's integrated regenerative braking system means its brake-by-wire setup can differ in specification from a straight petrol or PHEV 7 Series. Whether a caliper from, say, a 740i or 750e will physically fit and function correctly on your i7 is not something to assume — route this question directly to the breaker, giving them both vehicles' registration numbers so they can cross-reference part numbers before you buy.

Because the i7 uses a brake-by-wire system with electronic integration, some calipers — particularly at the rear — may require coding or calibration after fitting, so ask the breaker whether the unit has been tested and whether you will need a BMW-capable diagnostic tool at the point of installation. It is also worth confirming whether any mid-cycle specification changes apply to your car, as these are the kind of detail that is best checked against your registration rather than assumed from the model year alone. A reputable breaker will be able to cross-reference part numbers against your VIN to give you the best chance of a correct match.
