Cheap BMW M5 Brake Master Cylinder

Yes, every generation of the BMW M5 is fitted with a conventional hydraulic brake master cylinder — it is a standard component of the car's braking system regardless of which generation or engine variant you own. The M5 has always used a pedal-operated hydraulic setup, so a brake master cylinder is present on all of them. If your car has an electronic brake booster or iBooster fitted (more relevant to hybrid or very recent models), confirm with the breaker exactly what system your car uses before ordering.

No — the E39 M5 and the E60 M5 are entirely different generations with different braking architectures, subframe layouts, and in the E60's case a high-revving 5.0-litre V10 engine rather than the E39's 4.9-litre V8, meaning the systems are not interchangeable. Always source a master cylinder specific to your generation: E39 for the 1998–2003 car, and E60 for the 2005–2010 car. Confirm the exact part reference with the breaker against your registration to be certain.

Within a generation the master cylinder is generally consistent, but mid-generation brake system updates are a known possibility on performance cars like the M5 and we cannot state as fact whether any such changes were made part-way through the E60 run. Name your generation clearly to the breaker, and always ask them to cross-reference the part number against your specific registration rather than year alone.

No — the F10 and F90 are separate generations with significantly different chassis, braking systems, and in the F90's case a twin-turbocharged 4.4-litre V8 replacing the F10's naturally aspirated 4.4-litre unit, so the master cylinders are not the same part. The F10 generation ran from 2011 to 2016, while the F90 arrived for 2018; parts from either should only be matched to the correct generation. Always have the breaker verify the part against your registration.

The Competition badge on models such as the F90 M5 primarily brings suspension, software, and cosmetic differences rather than a change to the hydraulic brake master cylinder itself, so trim level alone should not affect which master cylinder is fitted. That said, if your car has any upgraded or different braking hardware confirmed by the factory for the Competition variant, check this with the breaker against your registration rather than assuming the parts are identical. The master cylinder itself is not a cosmetic item, so trim level is unlikely to be the deciding factor here.

Both years sit within the F10 M5 generation (2011–2016), so a cylinder from within that generation is your best starting point. However, whether any mid-generation brake specification changes affect interchangeability across those specific build years is something we cannot confirm with certainty, so route this to the breaker and ask them to match the part number to your registration before purchasing.
