1. When going downhill, some people want to save fuel, they hang up the gear, use inertia downhill, so the time is long, the brake pressure is not enough, easy to brake failure, so do not advocate hanging the gap, do not hang the gap, is Let the engine and transmission connect, the two layers mean 1. When going downhill, some people want to save fuel, they hang up the gear, use inertia downhill, so the time is long, the brake pressure is not enough, easy to brake failure, so it is not recommended to hang Neutral, do not hang up the gap, is to connect the engine and the transmission, this time when the car is downhill, not by inertia, but by the engine, it is as if the engine is taking you away, not letting your car go faster. This is one of the brakes.

2. Use the engine to brake the car, so that it slows down. If you don't step on the brakes and let the car slow down, you can easily hit the low-end car. There is no benefit to the engine!
Braking method Braking method includes oil pressure (car foot brake); mechanical (hand brake); air pressure and vacuum assist air pressure (wagon brake); spring energy storage (large truck foot brake hand brake); exhaust auxiliary brake (large diesel) Locomotive); engine idle assist brake (operation); electromagnetic turbine retarder (large passenger car).
In the five kinds of wrong foot brakes, the driver's bad action when using the foot brake directly or indirectly affects the driving safety, which should be paid attention to: First, the "point brake" method. The so-called "point brake" is when the brake is used (air brake system), the brake pedal is stepped on and then lifted up again and again. When the road surface is slippery and the adhesion between the wheel and the ground is low, the "point brake" pair is used. Preventing slippage during car braking has a role. The driver who has this habit thinks that the "point brake" spirit, when repeatedly braking and then lifting the brake pedal, causes the gas to enter each brake cylinder once and once, so that the air pressure in each cylinder is once It is higher than once, so the braking force is getting bigger and bigger, and the brake is better.

In fact, this is a wrong concept. The actual situation is that when the brake pedal is depressed, the brake master cylinder will connect the air reservoir and the brake cylinder, and the gas enters the brake cylinder to push the cam to open the brake shoe, and the vehicle brakes. The air pressure in the air cylinder is basically the same as the air pressure of the brake cylinder. As long as the brake pedal is not lifted, the consistency will not change, that is, the "brake" will continue. Some people have experimented and braked at a speed of 50km/h. The use of "point brake" is 1m more than the braking distance of one foot brake. If the pedaling speed of "point brake" is slower, the braking distance will be Longer.

The second is the foot shifting brake method. That is, when braking, the heel of the right foot does not move, and it is still below the original throttle springboard, but the displacement of the sole is placed on the brake pedal. The harm of braking using this method is: awkward, inconvenient, once there is In an emergency where sudden braking is required, it may be possible to slip off the brake pedal if the foot is too hard, which is more likely to occur if there is water or mud on the sole. Moreover, the height of the throttle springboard is inconsistent with the height of the brake pedal, and some of them are far apart. There is still a certain distance between them. The brakes are not well controlled by the shifting of the soles of the feet. The driver who uses the foot shift brake thinks that this method saves time faster than the entire foot shift brake, and can be actually tested and not faster than the entire foot shift. From the perspective of the design of the vehicle, it is not designed for the displacement of the foot (the height of the pedal and the accelerator pedal from the brake and the distance between them can be proved). That is to say, whether it is from the design point of view or the disadvantages that may be brought about in the operation, it is unscientific and unsafe to use the foot shift brake.

The third is the "floating" brake method. That is, the entire foot is removed from the pedal while braking, and the heel is also placed on the brake pedal. This phenomenon is very common, and the hazard is not only easy to slip but also inconvenient to control the degree of pedaling.

The fourth is to press the brake pedal method on the left foot. This kind of phenomenon often occurs in an emergency situation. If the vehicle is downhill or turning, etc., only a slight deceleration can be passed. Some drivers do not move in order to save the right foot on the accelerator pedal, but let the unskilled It is obviously unsafe to step on the brake pedal on the left foot.

Five is one foot and two usages. Both the brake pedal and the accelerator pedal are applied. This method of operation is also an emergency measure for experienced drivers after the hand brake is broken, and is generally not used.
