Is it okay to pull the handbrake in an emergency, and what happens if you pull the handbrake directl

Hello, a normal car with a sharp handbrake cannot stop the car at all, it only reduces the speed of the car.

Many car owners believe that in high-speed driving or sharp turns, in the event of a sudden crisis, you can directly pull the handbrake to slow down, in an emergency, the handbrake can replace the foot brake, so that the car immediately stops moving forward, in fact, this approach is wrong and very dangerous. If the owner pulls the handbrake at high speed, it will be easy to lock the rear wheels, the cable will be broken, and the phenomenon of side slip and rollover will occur. At the same time, when driving in sharp turns or rain, ice and snow, do not use the handbrake in a hurry, otherwise the ABS system will fail, and the rear wheel has no speed signal at all, which is prone to deviation and tail flicking.

1. The professional name of the handbrake is the auxiliary brake, which is different from the principle of the brake, which is connected to the rear brake shoe by using a steel wire to brake the car. Long-term use of the handbrake will cause plastic deformation of the wire, and since this deformation is irreversible, long-term use will reduce the utility, and the travel of the handbrake will also increase. The handbrake is complemented by a recovery spring.

When the handbrake is pulled up, the spring is elongated; The handbrake is released, and the spring returns to its original length. When the handbrake is used for a long time, the spring will also deform accordingly.

Second, the working principle of the handbrake for small cars, there is a brake disc after the gearbox, and the transmission shaft is connected to the place, similar to the disc brake (of course, there are also drum types), and then through the steel cable, the pull force is transmitted there, so as to achieve the parking brake. After pulling the handbrake, it uses a hydraulic auxiliary cylinder to push the hydraulic cylinder under the car to move, and then drive the air valve, (the reason why it is so designed is that the cab does not hear the sound of those air), and then after the air valve action, brake the transmission shaft, the car only brakes the transmission shaft with the handbrake, when the brake transmission shaft is completed, if it is an ordinary truck, the steel cable of the handbrake lever is used to pull and pull to achieve long-term braking, if it is a relatively high-end truck, such as Volvo's, then use electric control, Above, when you push the handbrake, there is actually an electric tractor that has been activated, and after the air braking is completed, it pulls the steel cable close and locks, of course, there is also a direct pull of the brake.

3. Precautions Handbrake is a system with a high usage rate, reasonable and correct use can make the future use smoother, especially for the largest number of mechanical handbrakes, better in accordance with the correct way to use, don't pull up the handbrake before the car stops, this practice is really not necessary. It is important for safety to save some use and ensure good use effect, and it can also extend its adjustment cycle and reduce the cost of maintenance and replacement.

When the car is in the driving state, the hand brake is suddenly pulled to death, which will have different consequences for different types of hand brakes. A mechanical handbrake may cause the car to lose control, while an electronic handbrake can slow the car down normally. But don't risk yourself, such actions are extremely dangerous.

Especially the mechanical handbrake, if the operation is not good, the car will roll over uncontrollably.

The structure and working principle of the mechanical handbrake is very simple, that is, using a lever principle, pulling a steel rope with the handle, driving the two rear wheel brake pads and the brake disc (or brake basin) to clamp and lock, resulting in braking effect. It must be noted that the mechanical handbrake brakes only the two rear wheels, and the front wheels have no stopping power.

In this case, the rear wheels of the car lock up, dragging on the ground, and ideally, the car will stay in a straight line, gradually slowing down until it comes to a stop.

However, in this process, as long as the rear wheel is affected by a little lateral force, it will immediately slide sideways, flick the tail, and even shake the rear of the car left and right, and the car in this state is extremely difficult to control, and it will generally lose control and roll over.

The braking force of the two rear wheels of the car cannot be exactly the same when braking, and the adhesion to the ground will not be completely equal, and the ground cannot be 100% flat, so it will be affected by the lateral force. That is to say, when the car is driving at high speed, if the hand brake is suddenly pulled to death, the car will definitely flick its tail, lose control or even roll over.

If the parking position is on a slope, be sure to brake well. When the slope is large, be sure to pull the handbrake to the end. On a parking ramp, it's absolutely impossible not to brake.

There are too many tragedies to prove it. In addition to the brakes, sometimes it is necessary to pull to the end. Many car owners can't stand to pull the brakes all the way to the end, because some cars are lighter in the front half and heavier in the back half.

At the critical moment, you must draw your hand to the end. Just in case, if you stop uphill, brake and step on another level.

When going downhill, pull down the hand brake and put the gear in reverse gear. The principle is that after shifting, the transmission gears are meshed, the slope is steep, and the force between the gears increases. In this way, the gear spacing becomes larger, which is not good for the car itself.

However, the next time you start, don't forget to set the gear to neutral before you start. It's also for safety. When we were learning subject 2 at driving school, the instructor would teach us to pull the handbrake all the way down after parking.

Therefore, many friends have developed the habit of "sudden braking", thinking that this is a good habit.

But in fact, most of the instructors in driving schools have a long service life, and in older models, the handbrake will become stronger. That's why the coach will let you do it. Most of the vehicles in real life are new cars, and the handbrake itself is relatively loose, and the owner no longer needs to brake vigorously.

Even in this case, if you brake suddenly, it will cause a certain amount of damage to the handbrake after a long time, and then maintenance is a big expense. During daily driving, it is best to keep a certain distance from other vehicles.

However, when the vehicle skids, a series of auxiliary measures such as braking and handbrake should be taken immediately. In addition, if you stop for a long time in town, you should still be vigilant and remember to brake the steering wheel. This will not only allow your feet to rest for a while, but also not worry about wandering and the brakes will slip.

To develop correct driving habits, be sure to pay attention to the dashboard while checking whether the handbrake is off before driving. On the contrary, the information displayed on the dashboard is the most comprehensive. Observe the information on the dashboard at all times, pay attention to the warning lights, and avoid handbrake driving.

The owner's car is automatic, so there is no need for a handbrake when driving. When parking, hang the P gear, and step on the brakes when encountering an uphill slope. If you drive like this, your feet will get tired.

I believe I have confidence in driving. In this case, I would hang in n gear and stop braking. A car Azhu joked, "The handbrake is not used to catch walnuts."

He couldn't understand that the handbrake wasn't for walnuts.

Of course, the injury must be pulled to the bottom of the ambush, if in the process of the first kill, if not resolute and decisive, it may make the car have a reverse accident; After the car stops driving, it is necessary to pull up the handbrake immediately, and when the car starts in the middle of the slope, it is necessary to put down the handbrake scumbag, and when the car stops in the middle of the slope, it is necessary to immediately pull up the handbrake, otherwise it will cause an accident that will slide and hit other people's vehicles in the middle of the slope.

Yes, this can better ensure safety, avoid rolling, and you can directly pull the handbrake after the car is stopped.

Yes, otherwise there is no way to use it normally, the handbrake must be pulled up when stopping, and the handbrake must be put down when walking.

1. Try to press and hold the handbrake buckle and then pull the handbrake

In order to prolong the service life of the spring and the small buckle, it is best to press the small buckle with the thumb and finger when pulling the handbrake and then pull the handbrake. This is more protective than pulling the handbrake directly without sound.

2. Pull the handbrake lightly

When pulling the handbrake, do not pull the handbrake up suddenly, as it will damage the handbrake for a long time. The correct way is to gently and coherently pull up the handbrake, and you can clearly hear the sound of the handbrake buttoning one by one.

The wrong way to pull the handbrake.

1. It is strictly forbidden to use the handbrake when driving at high speed.

When driving at high speeds, it is easy to pull the handbrake to lock the rear wheel of one side and cause side skidding, the correct way is to slow down by downshifting, and only pull the handbrake to stop the car when the speed is very low.

2. Park the car with a handbrake on the ramp for a long time.

Now there is a shortage of parking spaces, many parking spaces are planned to the slope, the owner will directly use the handbrake to fix the car after parking, because this will make the handbrake bear too much braking force, so that the handbrake wears faster, you can use a more practical method: bricks or other objects are padd under the tire, and then pull up the handbrake to let the wheels and the handbrake be stressed together.

When you pull the handbrake, you don't have to press the handbrake button, but you need to press the button when you stop to release the handbrake. The handbrake button is called the handbrake lock knob, which prevents you from misoperating and releasing the handbrake. So the correct way is not to pull the hand brake without the button, and when the hand brake is released, you need to press the button, and it cannot be released without pressing the button.

First, the scientific name of the handbrake is the parking brake, mainly to control the rear wheel, to put it bluntly, it is the rear wheel, generally used when parking on flat roads and slopes, the structure is very simple, mainly handles and buttons.

Second, the principle of the handbrake is to use the principle of lever, through the steel wire to pull the brake device of the rear wheel, mainly to see the locking teeth and teeth, these two parts are automatically occluded together

3. How to consume the handbrake correctly:

1. Pull the handbrake (brake the rear wheel), hold the handle with the right hand, pull it up, you don't need to use too much force, the tooth will automatically bounce up and bite the next tooth, and at the same time, the steel wire connected below will be slowly tightened, so as to brake the rear wheel brake pads (different car performance is different).

2. Release the handbrake (loosen the rear wheel): When the right hand holds the handle button, press the button with your thumb and press the button! Then press down on the handle, basically the handle can be pressed flat (the state before pulling up).

Fourth, the need to pay attention to:

1. Release the handbrake, press and hold the button (keep pressing the button) and press the handle down at the same time.

2. To what extent is the handbrake pulled? Parking on the slope can be pulled tighter to prevent slipping, and parking on the flat road can be pulled to seven or eight minutes;

3. The handbrake cannot replace the foot brake, and it cannot be in a pull-up state for a long time, because the steel wire will also be deformed after a long time, which will affect the braking performance.

4. Be sure to pull up the handbrake when starting, sometimes the handbrake will not be tightened when the road is flat, but at this time the car can start, if you forget to pull the handbrake, not only increase fuel consumption, power weakening, but also wear out the rear wheel brake device, and even heat and burn out the components, it is very easy to have an accident, now the model design is more humane, some high-configuration cars, the handbrake is not released at the start, and the system will have a warning report;

I only press when I am loose, and I don't press when I park, because I can't pull it tight when I press it when I park.

Do not press when parking. Press when you're ready to press.
