Its a circuit, the advantages are that they help start cars and other automobiles.
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.

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.
F1 cars need friction for their brakes, if they didn't have friction on there brakes then it wouldn't be able to brake.
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.
