No. Presently electromagnetic brakes are not used in cars but the can be used

No brake pads to wear out. Can't overheat the brakes.
No. Not yet, probably not anytime soon.
Copper is used in motors, brakes, wiring, radiators, connectors, and bearings in both cars and trucks.
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.
A brake tester is used to test brakes on vehicles. A brake tester is mostly used for testing the brakes of cars/auto-motives, but is also used for bikes and motorcycles.
In the past they used drum brakes but today all cars use disc brakes no matter if they are FWD or RWD.
the brakes or the emrgen see brakes
Well, considering the fact that cars don't work without brakes, Brakes were put into cars at the very beginning of car-time. Common sense, evidently, is something you lack.
no
Disc brakes have been used just about as long as there have been cars. The disc brake was patented by Frederick William Lanchester in England 1902.
Cars no but if you want to spend alot of money pickup trucks can. I personally am just going to keep the brakes I have on my truck.
You can learn all about the brakes in your cars and other cars by doing a simple search on your favorite SE. It's not hard to find out the steps to repairing your brakes.
