The Special Hydraulic Fluid called Brake Fluid is used for several reasons:
Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.

mechanical and hydraulic are two different power transmission medium. in mechanical brakes solid links or levers are used to achieve the required braking. in hydraulic brakes there are no links, here the braking is achieved by the hydraulic fluid, the hydraulic system in which the force applied at the brake pedal is multiplied several times to achieve the requied braking.
It was 1939 that Ford started to use hydraulic brakes.
Instead of using hydraulic brake fluid to apply the pads to the brake drums or discs, air pressure is used.
Because air is in constant supply - thus, a leak in the system won't necessarily render the brakes inoperable, whereas, with hydraulic brakes, the fluid would leak out until it had emptied.
In some cases, yes but NOT for hydraulic BRAKE fluid.
DOT ( 3 ) brake fluid is used for the hydraulic clutch and the brakes in a 1997 Ford Explorer Sport
A car has to have brake fluid to allow for the effective operation of the brakes to stop the car. When we apply pressure to the brake pedal, brake fluid, which is largely incompressible, will transfer that pressure to the pistons that operate the in the calipers or the pistons that operate the brake shoes. Further, the fluid must be of the correct type for the system in which it is used. The continued safe operation of the brakes may be compromised by the wrong fluid.
Hydraulic motors and hydraulic pumps are both components commonly used in hydraulic systems, and while they serve different functions, they share several similarities: Both are Hydraulic Components: Hydraulic motors and hydraulic pumps are both integral parts of hydraulic systems, which utilize pressurized fluid (usually oil) to transmit power. Both Convert Energy: While they convert energy in different ways, both hydraulic motors and pumps are involved in the conversion of mechanical energy to hydraulic energy or vice versa: Hydraulic pumps convert mechanical energy (often from an electric motor or an engine) into hydraulic energy by pressurizing fluid and creating flow. Hydraulic motors, on the other hand, convert hydraulic energy from pressurized fluid into mechanical energy, which can then be used to drive machinery or perform work. Both Operate via Fluid Flow: Both hydraulic motors and pumps operate by controlling the flow of hydraulic fluid. Hydraulic pumps create flow by drawing fluid into the pump and then pressurizing it, while hydraulic motors use the pressure of the fluid to generate rotational motion. Both Have Inlet and Outlet Ports: Hydraulic motors and pumps typically have inlet and outlet ports for fluid to enter and exit the component. In pumps, fluid enters through the inlet port and exits through the outlet port, while in motors, fluid enters through the inlet port to create motion and exits through the outlet port. Both Utilize Seals and Bearings: Both hydraulic motors and pumps often contain seals and bearings to prevent leakage and reduce friction, ensuring efficient operation and prolonging the lifespan of the components. Despite these similarities, it's important to note that hydraulic motors and pumps serve different purposes within a hydraulic system and operate in different ways to fulfill those purposes. While pumps are primarily responsible for generating flow and pressure, motors are designed to convert hydraulic energy into mechanical motion.

Those typically don't use brake fluid - they normally use air brakes. Can't really speak for the UK, but in the US, trucks with a Gross Vehicle Weight Rating of 26,000 lbs. or less tend to use hydraulic brakes, while vehicles heavier than that use air brakes. However, many of these vehicles with either manual or automated manual transmissions do use a hydraulic assist clutch, and brake fluid is what's used in those.
