Wires stretch and sag. Hydraulic fluids transfer force with far smaller losses.
both pneumatic & hydraulic systems are applications of fluid powers
It can not. Generally use press brake to bend sheet metal. Press brake has 3 kinds of series. Manual press brake by foot, mechnical press brake, hydraulic press brake.
Because oils damage rubber seals and hoses in the braking system, brake fluids are not petroleum-based. Most brake fluids used today are glycol-ether based, but mineral oil (Citroën liquide hydraulique minéral (LHM) and silicone (DOT 5) based fluids are also available.
Hydraulic drive systems like gear pumps, rotary vane pumps, screw pumps, bent axis pumps etc. One real life example of hydraulic pumps is the brake master cylinder in a car. You also see hydraulic pumps in excavators.
All modern mass-produced cars and light trucks DO have hydraulic brakes on the front and the rear wheels. Heavy trucks generally have air brakes on all the wheels. Maybe you are thinking of cars that have disk brakes on the front and drum brakes on the rear? On cars, these are both hydraulically operated using the same hydraulic (brake) fluid. In normal stopping situations, the front brakes do more work than the rear brakes. Maybe 70 or 80% of the braking is done by the front wheels (it depends on where the weight is in the car and how fast you stop). Disk brakes are a somewhat better brake for a car, but drum brakes are a little cheaper to manufacture. So, disk brakes are almost always used on the front wheels where the braking is more important. Drum brakes are used on the back of some cars to save money. Note that performance cars (sports cars) almost always have disk brakes on all of the wheels.

It looks like a hydraulic clamp. When hydraulic pressure is applied with the brake pedal, the caliper clamps the disc brake pads to the disc brake rotor to stop rotation.
Your brake fluid is how the brake system converts mechanical force of your foot on the brake pedal, into hydraulic force that applies your brakes. Without fluid, your hydraulic brakes will not function.
First production motorcycle with a hydraulic disk brake would be the Honda CB 750 in 1969
air in the hydraulic brake system
Air is in constant supply, so a leak in the air system won't necessarily cause a loss of braking power (a downside of the hydraulic brake system).
Hydraulic fluid?? Are you referring to Brake fluid? Dot 3.
