Clutch or brake first when you want to stop

Cars running at low speeds, such as when the speed is 20-30 km/h and below, generally press the clutch first, and then apply the brakes, which will prevent the engine from stalling.

In high-speed operation, the opposite is true. At this time, it is necessary not only to avoid emergency braking, but also to be careful not to step on it to death to prevent the car from sliding and causing potential safety hazards. Manual transmission models should first lightly step on the brakes, downshift, and use the engine to brake; After the speed has slowed down, press the clutch again to prevent the flameout.

In fact, on this issue, as long as you drive for a long time, when you have a sense of car, the corresponding feeling will naturally be found, usually on the road, whether to step on the brakes or clutch first, many old drivers will not think about it at all, it is all subconscious behavior.

Apply the brakes first, then the clutch.

When the vehicle is in motion when it is to be stopped, pressing the clutch directly will disconnect the power of the engine from the vehicle, and the vehicle will lose the braking effect of the engine itself. If there is an emergency and emergency braking is required at this time, the braking effect of the engine itself is lost, so the braking effect provided by the brake can only be braked, and the braking distance will be lengthened, which is more likely to cause accidents.

In the process of deceleration and coasting, the engine will provide a certain braking effect, which is often referred to as "engine braking". Because in the vehicle does not step on the accelerator and does not step on the clutch in the coasting state, the crankshaft of the engine is still connected with the rotation of the wheel, at this time, because the power output of the engine itself is very weak, only enough for the engine to maintain the idle level, so the actual situation is that the rotation of the wheel is driving the engine to rotate, and the rotation of the engine itself has frictional resistance, and this resistance is transmitted to the wheel through the crankshaft, and the deceleration of the wheel is realized until the engine speed drops to idle speed. Therefore, if you press the clutch in advance, the wheels will not be able to withstand this resistance due to the disconnection of the mechanical connection, and the braking distance will be increased.

That's why when we learn to drive at a driving school, the driving school teacher will also tell us that idling is safer.

Recently, some netizens sent a private message to ask; When learning to drive, if you want to stop, whether to apply the brakes or clutch first.

Clutch first or brake first, there should be many friends who learn to drive.

Apply the clutch first, then apply the brakes immediately to prevent the car from coasting and causing the car to go too fast.

Of course, the brakes are applied first, and the clutch is stepped on only after the speed slows down.

The best thing to do with the car is to clutch first, and then brake.

Let me talk about my opinion and experience, I have been driving for 31 years, and I have always been a semi-trailer and a big bus. If you are not an emergency stop, such as almost to the red light, you slowly slow down and brake, so the most fuel-efficient way is actually to first point the brake, and then almost arrive, feel that there is a drag gear in the gear and then step on the clutch to stop together, after stopping must pick up the neutral. If it is an emergency, then do not hesitate, two step on the brake together, the right foot on the brake and the left foot immediately press the clutch to the end (this problem is usually more difficult for novice or less experienced drivers to achieve, less experienced drivers usually step on the clutch first and then on the brake, or just just step on the brakes.)

Let's talk about the former first, so if you step on the clutch and then step on the brakes, you may have crashed; Speaking of the latter, the latter is simple, and it will definitely be extinguished. ）

Hello, I have 5 years of driving experience, I think it is better to clutch first and then brake when parking, as for the problem of fuel economy, I don't feel anything!

Clutch first and then brake is a taboo, this is not absolute, the actual driving depends on the situation, and it is not a dead brain. For hard braking, this is indeed a big taboo, because it will increase the braking distance of the car; However, if the speed of the car is slower at this time, the precedent of braking after leaving is a good way to avoid the car from turning off. So in general, when the car brakes suddenly, it should first lightly step on the brakes to slow down, then step on the clutch and brake, and at low speeds, first step on the clutch to cut off the power, and then step on the brakes.

Brake hard

Many people will think that the parking brake should be stepped on first, cut off the power, and the brake will be more effective, after all, the driving school instructor teaches it like this. But in essence, if the clutch is stepped on first when the vehicle speed is fast, the engine will quickly become idle, and the vacuum degree of the air tube will be reduced, and the auxiliary force of the vacuum booster will be greatly reduced.

That is to say, if you press the clutch first and then brake, the car will lose the engine brake, and then step on the brakes, the vehicle will shake violently, and the inertia of the car and the braking distance will increase. Therefore, you should apply the brakes first, and then press the clutch when the speed is reduced to close to stopping, which is predictive braking, and it should be smooth, and developing this habit can also argue that Kai can be prepared for accidents.

Low-speed braking

When the car is at a speed of 20-40 mph, first stepping on the clutch and then braking can prevent the car from stalling. On the contrary, if you step on the brake first and then step on the clutch, the car will undoubtedly turn off at this time, so the saying that "first clutch and then brake is taboo" is not absolute.

When the vehicle is parked while driving, when the high-end speed is relatively fast, if it is not an emergency brake, first step on the brakes, reduce the speed, and wait for the speed to drop to about 25 kilometers per hour, step on the clutch, and at the same time step on the brake. Pick-up parking. When the speed of the car in the lower gear is slow, it is necessary to press the wide circle clutch and brake at the same time.

If it is an emergency braking, directly apply the brakes, and use the braking system and the engine to brake at the same time, of course, the car will be suffocated, but the situation is urgent and safe. If it's not urgent, apply the brakes, and when the speed is low, apply the clutch and brake at the same time.

Braking, also known as braking, is the action of stopping or slowing down a running locomotive, rolling stock, or other means of transport or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install the corresponding brake shoe, belt or disc on the machine base, and make it produce braking torque under the action of external force. The brake device is a mechanical braking device that can slow down the speed of the vehicle, also known as a reducer.

Two separate cases:

1. When pulling over: when pulling over, the speed is generally slow, turn on the turn signal, observe the traffic on both sides through the turn signal, under the premise of ensuring safety, pull over, and when the vehicle adjusts the distance between the road and the road, step on the clutch, and then step on the brake, according to this operation, you can achieve smooth braking.

2. Parking at traffic light intersections: When passing through traffic light intersections, you can determine whether to step on the brakes or clutch according to the distance to the intersection. When the distance is not very far, you can release the throttle, use the gearbox to slow down, when the speed is relatively fast, you must slow down to the intersection by stepping on the brakes, first step on the clutch and then step on the brakes, and wait until the car is completely stopped after the gear is removed, pull the handbrake, and release the clutch and brake.

Parking Notes:

1. Do not occupy multiple parking spaces.

Sometimes, although a line is drawn in the parking lot, many times the place where two cars can be parked is occupied by one car, which is not good for others and oneself. Therefore, "novices" should not influence others to park for their own convenience. If the parking technique is poor, just reverse it a few more times.

2. You can't stop under the balcony window and next to the construction site.

Parking in this way, just into the upstairs bad habits and lack of morality of the "gun range" range, the light is to throw a cigarette butt, fruit peel and the like, heavy to throw a fruit pit, waste batteries and the like, in the wind and rain to fall a piece of glass and flower pot or something is not new, the consequences of this can be imagined.

In addition, the air conditioning water dripping from the water outlet of the outdoor unit of the air conditioner in summer is also easy to get on the car paint, leaving a mark that will be difficult to wash, not only the loss of money, but also the mood.

3. Don't stop under the tree.

Some trees will drop fruit, and the fruit will crumble when it falls on the ground or on the car, leaving the sap like phlegm, which is difficult to clean. It is easier to leave bird droppings under the tree, this thing is very corrosive, and if the car paint is not treated in time, it will leave scars, and it can be completely cleaned unless the paint is redone, so you should also pay great attention to parking under the tree.

4. When there are many empty parking spaces, do not park in the middle.

When there are several empty parking spaces at the same time, it does not mean that you can choose any parking space. Choosing a parking space is also a science, and the worst position is in the center. Because you have cars to your left and right, there is the highest probability that someone will accidentally knock on your door when they open the door.

In the middle of the two leftmost and rightmost parking spaces, the leftmost one is better. Because there is no car on the left side of your car, the car on your right side is the door opening side of someone else's driver. Drivers generally understand that they should open the door carefully so as not to hurt both sides. However, passengers who do not drive are less aware of this.

5. Park your car in a conspicuous place with good visibility.

Parking does not mean that you are not easy to be targeted by thieves if you park in concealment, on the contrary, those corners, monitoring corners, and poor lighting are the best places for thieves to start. The theft of the contents of the car is not a small matter, and the thief may directly steal the entire car. Therefore, you must choose a public location for parking, and the more people you see, the less likely you are to be stolen and pried.

Slow down by pressing the brakes when stopping, and then press the clutch pedal when the car is about to stop. The clutch belongs to the transmission system of the car, and this component is important for the car. The clutch is responsible for connecting or disconnecting the engine from the gearbox, and the clutch is installed between the engine and the transmission.

The pressure plate of the clutch is fixed to the engine flywheel, and between the pressure plate and the flywheel are the clutch plates.

Automobile History

In 1879, the German engineer Karl Benz successfully tested a two-stroke experimental engine for the first time. In October 1883 he founded the Benz Company and the Rheingas Engine Plant, and in 1885 he built the first Benz patented motor vehicle in Mannheim, which was a three-wheeled vehicle.

Powered by a two-stroke, single-cylinder horsepower gasoline engine, the car has some of the basic features of a modern car, such as spark ignition, water-cooled circulation, tubular steel frame, leaf spring suspension, rear-wheel drive, front-wheel steering, and brake handlebars. On January 29, 1886, German engineer Karl Benz filed a patent for his motor vehicle.

In November of the same year, Carl Benz's three-wheeled motor vehicle was granted German patent number 37435A. This is what is considered the world's first modern car. For these reasons, 1886 is generally regarded as the first year of the automobile, and some scholars regard 1885, the year of Karl Benz's first three-wheeled car, as the year of the birth of the automobile.
