Will replacement of brake master cylinder correct false messages on brakes such as check low brake fluid, break light or VSA systems?

Hello -- quick answer is - no one can have any idea until they perform needed electronic diagnostic testing referencing "C" Chassis modules with a tool capable of interfacing with the vehicle in this way. Referencing the trouble codes found with workshop manual and service bulletin data is required to figure out what's happening. Certainly. it's possible that the master cylinder could be at the root of the concern - but it's definitely not the only possible cause.
