It depends on what kind of car it is. Luxury and racing cars have 4-wheel brakes, but street cars have 2-wheel brakes.
Kinda-sorta. Usually the front brakes come on faster and harder, so at casual driving the rear brakes might not see much use at all. But at hard braking, all wheels will see some brake action.
ABS is an acronym for Anti-lock Braking System. An ABS has sensors on either two or four wheels. When you apply the brakes, the sensors detect a wheel lock and will quickly release braking pressure, then return braking pressure to normal. This keeps the car from skidding, which keeps you in control of the car. There are a few different ABS used by auto manufacturers. The least expensive to use is the rear wheel ABS, which keeps only the rear wheels from locking. This is used on larger trucks, where locking the rear is very unsafe. Some cars have a three channel ABS. Think of each channel as an ABS. Each of the two front wheels has their own channel and both of the rear wheels are on one channel (three channels). The Infiniti Coupe has a four channel system. Each wheel has its own ABS, so four wheels = four channels. This is the best ABS available, since each wheel can have the ABS work independent of what the other wheels are doing.
all wheel drive has power going to all 4 wheels all the time the vehicle is in motion My 1995 Ford Explorer is four wheel drive , it has a two wheel drive setting that powers the rear wheels , a 4x4 automatic setting where if the back wheels slip some of the power is transferred to the front wheels , and a 4x4 low setting that sends power to all 4 wheels continuously for off road use at reduced speeds
The three types of brakes are Pedal, Hand and Chin brakes. 1 Drum brakes on all four wheels 2 Disc brakes on front, drums on rear 3 Disc brakes on all four wheels.
It is not recommended to tow all four wheels down. Chrysler wants you to use a vehicle dolley and tow with either front of the vehicle up or rear of vehicle up in the dolley. Just reading from the service manual. I cant even find a procedure do it if you do tow with four wheels on ground. Hope this helps.
Almost all trains have wheels, although there do exist trains that use magnetic levitation and do not require wheels.
Use a water bottle and for the wheels use four water bottle caps and put a hole in the sides of the water bottle (use a big water bottle) and put holes in the caps too and use a straw to hold the wheels to the car and use tape to keep it all together. Good luck!
That all depends on what's most important to you; good braking or low weight. Disc brakes offers better braking but are heavier. Rim brakes are lighter, but braking will suffer in wet conditions.
Anti-lock brakes prevent the wheels from 'locking up' (i.e. stop rotating) allowing the driver to steer clear of an accident while braking and without skidding. The previous answer was correct but it is not true in all cases as using ABS on some surfaces i.e. gravel and ice will actually increase braking distance and a little more skidding.
A train has brakes similar to a car at every wheel (friction brakes), and also can use its locomotive power to apply a braking force (called dynamic braking). If any train wheels lock-up (stop moving) the sliding wheels do not slow the train as quickly as they are designed to do. In the US, modern locomotives use computerized braking systems, as do passenger trains. Freight cars are limited to the friction brakes and often this is where you may see a set of train wheels lock-up when they shouldn't.

The purpose of wheels is to transport you to all around the world. This is a very important use!
