If the brake fails at high speed, should I pull the handbrake?

If you are driving at high speeds, remember not to use the handbrake immediately to brake. Because at this time, once the handle is likely to cause a rollover, the correct way is to use the above method to reduce the speed first, wait until the speed of the car drops to 30km h, and then slowly pull the handbrake until the vehicle stops. If the vehicle is equipped with an electronic parking brake, it can be powered when the brake fails at high speeds.

Brake failure at high speeds is a very serious car failure. Although the probability of brake failure in daily driving is very small, once it happens, if it is not handled properly, it can have very serious consequences. Therefore, it is very necessary to master some emergency braking measures in advance.

1.Steady the direction and turn on the double flash. When the high-speed brakes fail (you can also refer to the situation of a puncture), the first thing to do is to stabilize the direction to prevent collapse, stabilize the steering wheel, and let the vehicle continue to slide.

At the same time, turn on the double flash to remind the Bi Yin vehicle next to it, and first use the wind resistance and friction to slow down by itself. Brake failure can also be due to short-term failure of components such as brake fluid or vacuum pumps. If the distance between the vehicles is within a safe range, you can try to press the brake pedal frequently to wake up the braking system.

2.Downshift with the handbrake. If the brakes really fail, we can use the engine brakes to slow down the car by downshifting.

Manual transmission models: Continuously lower the current gear to a low gear (e.g. 5th gear, 4th gear, 3rd gear, 2nd gear, 1st gear). At this point, the speed of the vehicle decreases, and then the handbrake is used to brake.

Most models are now equipped with an electronic parking brake with dynamic emergency braking. After attaching the low gear, you can directly try the handbrake, and the ESP will intervene to hydraulically brake the four wheels, which is much safer than the ordinary handbrake. Automatic transmission models:

Hands can be downshifted one by one, and snow mode can also be used to reduce speed. Handbrake method: After the brake fails, you can use the handbrake to brake.

The correct way is to slowly pull down the handbrake, tighten, loosen, tighten, and release the vehicle several times, and slow down to stop. It should be noted that when pulling the handle of the handbrake, the safety button of the handbrake handle should be pressed, so that the handbrake handle can be operated freely in the process of tightening and releasing to prevent the handbrake from locking up when tightened. 3.

Use emergency escape routes. If the handbrake and downshift don't work, the driver honks loudly to warn the surrounding vehicles to give way, and then slows down on the appropriate section. Many highways have emergency escape lanes on or off the slope of the road.

There will be pools of sand and water in the driveway to help the vehicle slow down. If the brakes fail, you can pull over next to the emergency escape route. 4.

Take advantage of the obstacles around you. If none of the above works, consider using roadside obstacles such as walls, trees, railings, etc. ) to reduce the speed.

Of course, this is also a last resort, because it is not only dangerous, but also can damage the moving vehicle. It should be noted here that when braking with this method, the front of the car must not directly hit the obstacle. If the obstacle is on the driver's side, do not lean on the obstacle, which will directly affect the driver's life safety.

In short, there are risks associated with any of the above methods, and the best way is to prevent them from happening. It is necessary to develop the habit of checking the brakes at ordinary times. Pay more attention to whether the braking distance is longer and whether the braking is slow.

Before entering the highway, uphill and downhill sections, it is even more important to get into the habit of testing the brakes. Step on the brakes and test if the brakes work.

If the brake fails, the handbrake can be pulled.

In the case of low speed, you can use the handbrake to slow down, but it should be noted that the handbrake cannot be pulled down suddenly, otherwise it will directly damage the handbrake system, cause the handbrake to fail, and even cause the car to slide sideways; The correct method should be to brake lightly, and repeatedly tighten and release until the vehicle stops; Use roadside obstacles to reduce the speed of the car, rub the side of the body, do not approach violently, and rely on a little back to avoid deformation of the cab and injury to the driver.

The electronic handbrake is the most trustworthy for the failure of the foot brake, pay attention to the operation of the electronic handbrake, and the same as parking, it is not effective to just pull once, and it needs to be pulled for a long time, so that it can work. It has more stopping power, is faster, and most importantly, the car doesn't get out of control when you brake.

If your car is a mechanical hand brake, you can also brake hand brake, but be careful, when the speed is relatively fast, you must not use it, otherwise the loss of control is within a few minutes. This is because the handbrake only brakes the rear wheels, and the electronic equipment cannot participate in the work, if the braking force of the rear wheels is too large, or even when the wheels are locked, the direction is slightly turned, and the car will immediately lose control of the tail, so when the hand brake is turned on, it will not be able to play the direction in essence.

If the owner is driving at high speed, if the handbrake is easy to cause the vehicle to roll, when the speed is fast, the owner must gently pull the handbrake to avoid accidents. In addition to the manual handbrake, there is also an electronic push-button handbrake, which allows the owner to successfully brake by simply holding the electronic key handbrake. If the owner experiences a braking failure while driving the vehicle, the absolute measure that cannot be taken is to stall, which will lose steering and braking power, and will also cause the engine to brake malfunction.

When our brakes fail, we can use the handbrake to stop the car. If you have an electronic parking brake, you can use it to assist with braking; If it is an old-fashioned mechanical cable-type handbrake, it can also be used in an emergency, but it is necessary to be very careful in the process, if the speed of the car is too high, do not pull the handbrake immediately, there will be a risk of losing control and flicking the tail.

The electronic handbrake is the most trustworthy after the foot brake fails, pay attention to the operation method of the electronic handbrake, and the same as parking, only pull it is not effective, you need to pull it for a long time, and you must release the throttle, so that it can work. Its braking force is relatively large, it can brake the car quickly, and the most important thing is not to let the car lose control, and there will be ABS, ESP to participate in the work when braking to maintain the stability of the vehicle.

If your car is a mechanical handbrake, you can also pull the handbrake to brake, but be cautious, do not use it when the speed is relatively fast, otherwise it is a matter of minutes. This is because the handbrake only brakes the rear wheels and the electronic equipment can not participate in the work, if the braking force of the rear wheels is too large, or even the wheels are locked, the direction is slightly turned, the car will immediately lose control and flick the tail, so the handbrake can not be greatly hit after the direction.

When the brakes fail, we can use the handbrake to stop the car. If there is an electronic parking brake, it can be used to assist braking; If it is an old-fashioned mechanical cable handbrake, it can be used in an emergency, but special care should be taken during use. If the speed is too high, do not pull the handbrake immediately as there is a risk of loss of control and tail flicking.

After the foot brake fails, the electronic parking brake is the most reliable. Pay attention to the operation method of the electronic handbrake. It's like parking, useless.

It takes a long time to pull and the throttle must be released to work. It has a relatively large braking force and can brake quickly. The most important thing is not to let the car get out of control.

ABS and ESP will be involved in the braking process to maintain the stability of the car.

If your car has mechanical brakes, you can also brake with the handbrake, but be careful not to use it when the speed is relatively fast, otherwise it will take a few minutes to lose control. This is because the handbrake only brakes the rear wheels, and the electronics cannot be involved in the work. If the braking force of the rear wheels is too large, even if the wheels lock up and the direction is slightly steered, the car will immediately lose control and flick its tail, so you can't hit the direction sharply after turning on the handbrake.
