We should probably start by saying a Brake Master Cylinder technically is not essential. You could use cable-actuated brakes, if you liked, like the cheap items you get on entry-level mountain bikes. On the other hand, to stand the strain of stopping one or two tonnes of metal, plastic and humans over 10-20 years, the cable would have to be massive.

There are more practical solutions, chief among which are hydraulics. The fact that liquid does not compress makes it perfect for transferring force from one part of a system to another. When it comes to the brakes in your car, the master cylinder is the key component in making that happen.
