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.
Cars have improved in many ways. The advent of seat belts, safety glass, anti-lock brakes, air bags, power steering and power brakes have all improved cars.
The improvements in railway transportation that were brought about by new technology were Air Brakes, Car Cupplers, Refrigerated cars, Sleeping cars and Dining cars.
In all cars and most trucks HYDRAULIC pressure is used to apply the brakes. In an air brake system such as is found on medium and heavy duty trucks the air is actually released to apply the brakes.
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.
No, they use air pressure or actually the lack of air pressure to stop the vehicle. The brakes are fully on until pressure builds up in the tank releasing the brakes. When you push the brake pedal this removes air from the system and applies the brakes.
No. Presently electromagnetic brakes are not used in cars but the can be used If I may finish that..on trailers
Pumping gently will reduce friction, produce less heat and help the brakes last a little longer. This procedure is not recommended if you have a truck with air operated brakes.
We would need to know what type of brakes you have... S-cam air brakes, air disc brakes, air piston brakes, air wedge brakes, hydraulic drum brakes, hydraulic disc brakes... they're all different.
Air brakes are just as effective as a standard set of brakes. The advantages to air brakes are that you do not have to worry about leaking brake fluid.
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.
Compressed air.
