1. Use engine brake to match hand brake
① Automatic gear model: when the vehicle brake fails, first release the accelerator pedal, and then shift the gear to the manual gear, and then lower it from the high gear to the low gear. In general, the automatic gear model does not have such obvious braking effect as the manual gear model. Some models also prohibit the automatic gearbox downshift in order to protect the gearbox, so each downshift should be matched with the hand brake to reduce the speed Then lower the gear in turn. Similarly, when you pull the handbrake, you should press and hold the release button. You can pull the handbrake continuously for a while, but you can't pull it. The same is true for the electronic handbrake. Press it after you pull it up until the vehicle stops and puts it in the parking gear.
② Manual gear model: when the brake of the manual gear model is found to be out of order, release the accelerator pedal first, step on the clutch to continuously downshift, which will generate traction for the engine, and produce braking effect on the driving wheel of the vehicle through the traction of the engine. When the gear is downshifted to the first gear, cooperate with the handbrake to slow down. Note that when the handbrake is pulled, press and hold the release button, one after another continuously Pull the handbrake down, and do not pull it to the limit, otherwise it will easily lock the rear wheel, which will cause the vehicle to lose control again.
2. Use of terrain or emergency escape Lane
If none of the above methods can stop, turn on the vehicle warning light, sound the whistle to remind the vehicle ahead to make way for you, and find the appropriate road section to slow down in time, such as the emergency escape Lane set up on the uphill road or expressway or continuous downhill section. The emergency escape lane is on the right side of the main lane, and many highways will be set in the continuous downhill section or downhill section of the highway. If the brake fails, you can try to enter the emergency escape lane, and the lane has gravel to help slow down.
3. Use of roadside obstacles
If none of the above methods are applicable, only the roadside obstacles can be considered to reduce the speed of the vehicle. Of course, this is the inevitable method, because it is not only dangerous, but also will damage the driving vehicle. If there is a mountain wall or highway guardrail on the right side of the vehicle, drive the vehicle slowly to the roadside, grasp the steering wheel with both hands, and rub against the mountain wall or guardrail.
