What effect does the car handbrake have on the car all the time

A normal car with a sharp pull on the handbrake does not 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.

As a kind of auxiliary brake, the handbrake is mainly designed for parking brake and to prevent the car from skidding, and is often used when driving. But did you know that in fact, using the handbrake is also a learning problem, so what kind of impact will the handbrake have on the car? Let's take a look.

First of all, the handbrake is connected to the rear brake with a steel cable, which has a braking effect on the car. The handbrake cable looks like a solid steel cable on the outside, but it is made of nylon on the inside, which plays a key role. If the handbrake is pulled to the end for a long time, the service life of the handbrake cable will be shortened for a long time, and then the nylon material will gradually lose its elasticity, and the steel wire of the handbrake will be irreparably deformed, and the decline of the reset function will easily lead to a decrease in braking performance, thereby increasing the braking stroke, and even leading to the failure of the braking effect.

So the correct way to operate should be to pull the handbrake to two-thirds of the limit when pulling it, and this position is also easy to find. Like the pedal of the foot brake, the handbrake lever also has a pull stroke. When parking, slowly pull the handbrake and count the ratchet clicks as you pull until you pull your hand to the end.

But don't pull the handbrake when driving at high speeds. Although we can often see in movies that the handbrake is pulled for emergency braking in an emergency, these can only be seen in movies. Once the handbrake is pulled during high-speed driving, it is easy to lock the rear wheel on one side and cause side skidding, which may also cause the handbrake line to break and the vehicle to roll over out of control.

Therefore, the correct thing to do is to slow down by downshifting, and then pull the handbrake to stop when the speed of the vehicle decreases.

Also, don't use the handbrake to stop on the ramp too often. I believe that whether on a road trip or out for work, many car owners will inevitably park their cars on ramps. Many car owners usually pull the handbrake directly for convenience, but the most correct way is to pull the handbrake after parking, then get out of the car and put some big stones on the rear wheel.

The purpose of this is to reduce the braking of the handbrake and play the role of auxiliary parking. Otherwise, the use of the handbrake alone will cause the handbrake to be subjected to excessive braking force, which will not only fail to achieve good braking efficiency, but also easily lead to handbrake wear.

The effects of pulling the handbrake to drive the car are as follows:

1. Pull the handbrake to drive, the most direct hazard is that the brake disc accelerates and wears out, the brake pad becomes hard after heating, and the handbrake cable is elongated. This results in a decrease in braking performance, which can sometimes lead to a smell of burning, and in severe cases, smoke from the rear of the car. If you pull the handbrake for a long time to drive, it may also lead to the brake cylinder biting, brake fluid leakage, and the brake fluid temperature is too high, resulting in the complete loss of brake function.

2. Generally speaking, when driving with a handbrake, the faster the speed, the greater the loss of the brakes, and at the same time, it will also damage the tires. Car owners must develop correct driving habits, before driving to see whether the handbrake has been released, but also pay more attention to the dashboard, relatively speaking, the dashboard shows the most comprehensive information. Observe the information on the dashboard at all times and pay attention to the warning lights to avoid driving with the handbrake.

3. If you drive with the handbrake, you will obviously feel that the car is slow, the frustration is obvious, and the engine speed is high. Emergency measures: If you encounter driving with the handbrake while driving, and there is a serious burnt smell and smoke from the rear of the car, the owner should immediately slow down, brake, and put down the handbrake.

At this time, do not continue to move forward, park the car on the side of the road, wait for the temperature of the car to cool down, and carefully observe if there is anything else. Don't just drop the handbrake and continue driving while the car is still hot.

The correct way to pull the handbrake

Try to press and hold the handbrake buckle and then pull the handbrake; Pull the handbrake lightly; Pay attention to the best working point of the handbrake, the best working point of the handbrake is to pull up 70%. Some people will forget to release the handbrake when starting, this situation is normal, especially novice drivers, and the novice damage to the car is very large, so you must pay attention to the correct method of handbrake.

Can not use the handbrake to replace the footbrake, many novice friends in the driving in order to avoid the brake as the accelerator, will subconsciously come up with the handbrake instead of the footbrake, in fact, this method is particularly dangerous, in the process of driving, if the handbrake is pulled, it is easy to break the handbrake cable, then, you will have an unpredictable accident.

If the foot brake fails when the vehicle is driving in a straight line, you can pull the handbrake to help slow down until it stops. However, if the handbrake is on one side, it may cause the car to deviate.

The braking system of the car determines the safety of the car. If the car's handbrake works for a long time, the car's handbrake will wear out severely. Although the car's handbrake will wear out while driving, the handbrake will still be pulled while driving, which has a lot of pressure on the handbrake, there is a possibility of failure, and it is also very dangerous if the handbrake is used.

This is the most serious case. If the handbrake is pulled for a long time, the friction will increase. When you pull the handbrake for a long time, the heat reaches the limit value, which can cause the handbrake pad to catch fire.

Many car fires tend to be due to some detailed reasons, so you should do a good job of checking while driving. Nowadays, many cars are equipped with safety warnings, so you can find some potential safety hazards at the first time, if you smell the smell of burning while driving, you should stop and check in time to prevent greater danger.

If you forget to pull the handbrake when parking, and forget to apply the footbrake when the vehicle is reversing, there may not be much danger. But if you are stuck in traffic on a half-slope and the owner forgets to pull the handbrake, it will be very dangerous. At this point, the owner's energy is spent on pressing the accelerator and releasing the clutch, and the foot brake is neglected.

At this point, the vehicle will slide downward. In addition, other vehicles behind him constantly honked their horns, which made the owner even more nervous. When he hastily lifts the clutch, the vehicle will stall and then quickly back away in order to meet the vehicle behind him.

If you see smoke coming out of the back of your car while driving, it's most likely because of a problem with the handbrake. If you find abnormal smoke in the exhaust of your fellow vehicle, you should also remind the owner to deal with it as soon as possible to avoid further damage. Pulling the handbrake to drive will undoubtedly increase the drag of the car.

It needs to increase the throttle to drive the car. This not only affects the fuel consumption of the car, but also the engine performance of the car. This is similar to low and high speeds, but the impact will be greater.

If you suddenly notice that your vehicle is unable to accelerate or even roars while driving, do not continue to press the accelerator. Since the rear wheels of the vehicle are locked, the vehicle is towed by the front drive wheels. Stop for inspection as soon as possible.

If rear-drive steering or high-speed steering is possible when the rear wheels are locked, there is a high chance of sideslipping or tail flicking. Pulling the handbrake to drive will undoubtedly increase the drag of the car. It needs to increase the throttle to drive the car.

This not only affects the fuel consumption of the car, but also the engine performance of the car. This is similar to low and high speeds, but the impact will be greater.

It will cause serious wear and tear on the car, the brake pads of the car are seriously worn, and there may even be brake failure, and the brake pump will bite the brake fluid leak. If the temperature of the brake fluid is too high, it will directly affect the engine of the car, causing the car to stall or serious white smoke.

The most direct impact is that the brake disc will accelerate the wear, and the brake pad will even produce smoke if it is overheated, resulting in poor braking effect, and in severe cases, it may also lead to brake fluid leakage and loss of brake function.

The direct effect is that it will accelerate the aging and heating of the brake disc, and then harden. This leads to a decrease in the car's braking ability. And the body shakes violently. In severe cases, it can lead to accidents.
