There are many cases brake, the car's different, different braking techniques, different roads, braking skills course will be different, even if the same car, same road, the speed of different methods have different brakes, today I talk about road vehicle on the highway brake basic knowledge and basic skills.
A: Basics:
1: front brake more quickly than the rear brakes.
2: front brake than the rear brakes more secure.
3: two brake faster than a brake.
4: dry brakes brakes more quickly than the wetlands.
5: asphalt concrete pavement is more than fast.
6: Please do not try to point the best brakes.
7: you better not brake in the corners.
Now I explain one by one.
1: In the driving brake, rear wheel friction can not give you enough to make you stop faster, while the front wheel can, because, in driving the use of front brake, the car will shift into the inertia of forward downward force, then, the front wheel will be greater than the friction of the rear wheels,

2: in a moving kind of a little harder (especially when high-speed) of the rear brake will cause the rear hold S, produce sideslip, and the front wheel as long as you do not have ridiculously large force to brake, will not produce side slide (of course, the road to clean,
derrick rose jerseys, the car should be upright)
3: a good understanding, certainly with two brakes with a brake than just how fast. (Nonsense)
4: dry road surface than the water brake quickly because the water will form a layer between the tire and the ground water film,

5: cement ratio of asphalt pavement in the face of the tire friction is small. Especially when there is water on the ground. Because the rough asphalt road surface than the cement.
6: Point the brakes on the car's relatively high demand, and similarly, the requirements of the driver is also relatively high, of course, you can try, however, point the brake is not meaningful for the road car.
7: in the corners, the adhesion of the tire to the ground is quite small, the brake force will cause a slight slip, fall.
II: Basic Skills:
1: high-speed front-wheel braking when the intensity must be greater than the strength of the rear wheels.
2: high-speed front-wheel braking force when the front wheel must not hold S.
3: uphill braking, the front wheel braking force can be appropriately larger.
4: downhill braking,

5: emergency brake, the brake force is slightly smaller than the intensity of S hold.
6: wet roads when braking,

1: high-speed braking braking force distribution, in general, 60-90, after the first 6 4.90 or more, after the first 7 3.120 2 after the first 8 or above. (Of course, not absolute)
2: well understood, hold the front wheel had to somersault S, Oh.
3: uphill, when the front wheel higher than the rear, so the front brake to the appropriate multi-point force.
4: above a turn.
5: Because, after the tires hold S, but will reduce the friction, the friction of the tire is the largest holding in the upcoming S, but S does not hold the critical point and has no way to explain more clearly, too trouble.
6: wet roads first before using the brakes, is likely to hold the front wheel S, the result is sure to fall, while the rear holds S, (as long as the car is a shelf, the front is) generally can not fall. Very simple.
Finally,
cheap barcelona jersey, add that, never expect to get enough in the corners braking force, the reasons see section 7 of the basic knowledge, then in the corners really need the emergency brake how to do? Keep in mind that the first thing you are not the brakes, but the pull is your car
