What to do if the brakes fail? What should I do if the brakes fail?

When encountering brake failure, the first thing to do is to calm down, do not operate casually, grasp the steering wheel, release the accelerator pedal, turn on the hazard warning lights (double flashing lights), try to step on the brakes a few more times, once the brakes have an accident, you must know how to repeatedly press the brakes several times, which will put pressure on the braking system with air in the oil pipe, and it is possible to recover part of the braking force.

The downshift brake of automatic transmission models is usually not as effective as manual transmission, but it can also be decelerated with the handbrake, and if you encounter the electronic parking brake, you can try to pull up and press multiple times until the vehicle stops, and then hang to P gear.

Step 1: When you find that the brakes are failing, try to apply the brakes repeatedly, and if possible, you can switch from high gear to low gear and use engine traction to slow down.

Step 2: After the speed of the vehicle is reduced, you can use the handbrake to brake (electronic parking brake is also possible). If the speed is too high to be controlled with the handbrake, consider using roadside obstacles to slow down or stop.

There are many reasons for brake failure, one is the lack of necessary maintenance of the brake system, too many impurities in the brake master cylinder, poor sealing, vacuum booster pump failure, excessive dirt of brake oil or air resistance after the mixed use of several brake fluids, oil leakage of the brake master cylinder or sub-cylinder, air leakage of the gas tank or pipeline interface; The second is the failure of the parts due to improper operation, such as long-term downhill will cause the brake pads to rub and heat, the brake hub to carbonize, and the brake function to completely fail; Third, due to serious overload, under the action of gravitational acceleration, the inertia of vehicle movement is increased, which directly leads to brake failure. What should a novice do if the brakes fail while driving? 1.

Control the direction according to the road conditions and vehicle speed, disengage the high-speed gear, and at the same time quickly empty the fuel and shift the high-speed gear into the low-speed gear. In this way, the engine will have a lot of traction resistance and the speed of the vehicle will be reduced rapidly. In addition, the handbrake should be used in conjunction with the low-speed gear shift, but it should be noted that the handbrake should not be tightened or pulled too slowly.

If it is pulled too tightly, it is easy to make the brake disc "lock", and it is likely to damage the transmission parts and lose the braking ability; If it is pulled too slowly, the brake disc will wear and ablate and lose its braking effect. 2.Use the bumper, carriage and other rigid parts of the car to rub and collide with natural obstacles (rocks, trees or soil slopes) on the side of the road to achieve the purpose of forcibly stopping and getting out of danger, and reduce the accident loss as much as possible.

3.If the brakes fail when going uphill, you should reduce to the middle and low gear in time to maintain enough power to drive up to the top of the hill and stop. If you need to park on a half-slope, you should keep the forward low gear, tighten the hand brake, and the personnel with the vehicle should use stones, skids and other objects to jam the wheels in time.

If there is a backward slippage, the rear of the car should face the hillside or the safety side, and the headlights and emergency lights should be turned on to attract the attention of the vehicles in front and behind. 4.When the downhill brake fails and the speed of the vehicle cannot be controlled by the mechanism of the vehicle itself, the driver should decisively use natural obstacles, such as rocks and trees on the side of the road, to cause resistance to the car.

If you can't find a suitable terrain or object to use for a while, in an emergency, you can move one side of the car closer to the side of the mountain, and gradually reduce the speed of the vehicle by rubbing to increase the resistance. 5.When the vehicle is descending a long slope or a steep slope, the vehicle should apply the brakes regardless of whether there is a situation or not.

It can not only test the performance of the brakes, but also buy time to control the speed of the vehicle when the brakes are found to be out of order, also known as predictive braking.

Emergency braking refers to the rapid and correct use of the brakes by the driver to stop the car in the shortest distance when the car encounters an emergency while driving.

The brake device is a mechanical braking device that can slow down the speed of the vehicle, also known as a reducer. To put it simply: the car brake pedal is under the steering wheel, and when the brake pedal is pressed, the brake lever is pressurized and transmitted to the brake pad on the brake drum to jam the brake wheel, so that the car slows down or stops running.

When you find that the brakes are abnormal, you can't be careless, it is likely to cause brake failure. What should I do if I experience brake failure? Three tricks to get it done.

The solution to brake failure is:1. Release the accelerator pedal;

2. Hang the gear to manual mode, and manually lower it from high gear to low gear in turn;

3. When pulling the handbrake, you should press and hold the release button to pull the handbrake continuously, and you can't pull it to death;

4. After the vehicle is stopped, it is put into parking gear;

5. You can also look for trees or walls. When the speed of the vehicle cannot be controlled, it should be controlled to drive in the direction of trees or walls, and use the bumper, compartment and other solid parts of the vehicle to collide or rub against obstacles to achieve the purpose of forced stopping, and avoid hitting pedestrians or other vehicles as much as possible.

The braking system is an important part of the car.

Once something goes wrong, the likelihood of a car accident is much higher for the car owner. So, what to do if the brakes fail at high speeds? For veteran manual transmission drivers, when the brakes are ineffective, the correct approach should be to use the low-speed anti-drag engine to brake at high speed; For automatic transmissions, it is necessary to change the automatic mode to manual mode for downshift braking.

Automatic cars can be hung in "2" gear and then "L" gear, not in "P" and "R" gears, and try not to hang "N" gear. The downshift brake of automatic transmission models is generally not as effective as that of manual transmission, but it can also be slowed down with the handbrake. If you play the electronic parking brake, you can try to "pull up and press and pull up" a few times until the vehicle stops, and then hang the "P" gear.

1.Stay calm and turn on the double flash. If you encounter brake failure, the first thing to do is to calm down.

Don't panic and rush too much. At the same time, double-check that you and the other passengers in the car are wearing seatbelts. Turn on the double flashes to warn the vehicle next to you to stay away from you.

In addition, even in the event of failure, the owner constantly tries to apply the brakes. Brake failure is most likely caused by brake fluid or other problems. Even if you feel like the brakes are failing, it's possible that the braking force hasn't completely disappeared.

2.Avoid pulling the handbrake directly. Most people may simply pull the handbrake when the brakes fail.

However, if the car is driving at high speeds at this time, the rear wheels may be locked by the handbrake, causing the vehicle to roll over without control. 3.Look for an escape route.

If none of the above works, then all the owner needs to do is quickly find an escape lane. If not, you can only use your body to rub against guardrails, mountains or other obstacles to do a forced deceleration. During this process, it is forbidden to hit the obstacle directly with the front of the vehicle, but to rub the entire body several times to reduce the risk of injury.

There are several situations when braking is abnormal:

1. New car running-in.

Due to the long parking time of the new car in stock, and the brake disc is easy to rust and rust, there will be abnormal sound when stepping on the brake during the run-in process of the new car, and the abnormal sound is not so obvious after more than 200 kilometers of running-in, and the braking will be more powerful.

2. Replace the new friction pads or brake discs.

If the worker does not chamfer the new friction plate, or does not apply the silencer paste, it is easy to have abnormal brake noise, and after replacing the new brake disc, it cannot have a good run-in with the friction plate, and there will be abnormal noise.

3. The gap between the hard foreign body entering the brake pad and the brake disc.

Generally, after wading, or walking on mud roads, etc., the hard sand and gravel will run into the gap of the braking mechanism, and there will be stagnation when the braking system is working, and the brake will make abnormal noise when running to the gap of the brake disc.

4. The braking mechanism is loose.

It is common that the brake caliper is not marked tightly in accordance with the specified torque when installed, and the brake pad is not fixed well when the brake disc is not tightly fitted with the brake disc when driving, and there will be abnormal noise.

5. Intervention of ABS in special circumstances.

Usually in the case of emergency braking, due to the driver slamming on the brakes. In order to avoid the locking of the wheels, the ABS system slightly hides the car and releases the brake at the moment of locking, and clamps the brake disc again, which can effectively reduce the situation of tail flicking, so the wheels may have a short abnormal sound in the case of high-frequency locking and release.

6. Use inferior brake pads.

The inferior brake pad texture is relatively hard, its metal content is high, the friction between the hard brake pad and the hard brake disc is easy to produce abnormal noise, the brake is easy to heat up for a long time, the light brake is weak, the heavy brake fails, it is recommended to choose the quality of the brake pad stove, after all, for the sake of safety.

7. The friction plate is worn to the limit.

Generally, the friction pad is worn to a certain value (generally about 5mm), the vehicle system will send out an alarm, and the owner is advised to replace the brake pad, if you continue to use the metal worn to the brake pad, it will cause abnormal noise.

8. Brake dragging.

When the driver touches the brake, the brake is still in the braking state, which is caused by brake lag, poor brake return effect or broken or failure of the brake master cylinder return spring, which is also caused by brake lag.

When it comes to brake failure, I believe that every driver wants to be touched, but we have to plan ahead. The following is an emergency method for brake failure, I hope it will help you. What should I do if the brakes fail during normal driving?

1) When the brakes fail or fail, turn on the warning light. Stay calm, hold the steering wheel tightly, release the accelerator pedal immediately, familiarize yourself with the road conditions and the terrain ahead as much as possible, control the direction, and disengage the high gear. Use engine braking, use steering to avoid obstacles as much as possible, and use methods such as parking brake or "gear rushing" to slow down and stop as much as possible.

2) When using the parking brake (handbrake), it is not allowed to tighten the control lever at one time, which is easy to "lock" the parking brake disc, damage the transmission parts, and lose braking force. While turning the steering wheel to avoid dangerous targets, you can take a "rush" operation according to the situation, use the drag function of the engine to slow down the vehicle as much as possible, and finally drive to the side of the road to stop. (3) Avoid people first, then avoid objects, choose a safe parking place in advance to avoid accidents caused by pedestrians.

What should I do if the downhill brake suddenly fails? When the brakes fail when going downhill and the speed cannot be controlled by the vehicle's own mechanism, the driver should decisively use natural obstacles, such as roadside rocks and trees, to cause resistance to the vehicle. If you can't find a suitable terrain or object to use for a while, in an emergency, you can move the side of the vehicle closer to the hillside, increase the resistance through friction, and gradually reduce the speed of the vehicle.

1) Check for obstacles on the side of the road, ramps can help slow down, or wide areas can be detoured to slow down and stop. It is best to use the emergency stop lane on the right side of the road to park. After parking, the parking brake lever should be tightened to prevent the car from skidding or secondary danger.

2) If there is no available terrain and timing, the accelerator pedal should be quickly lifted to "grab gear" and use the sudden increase in the transmission ratio and the resistance of the engine to reduce the vehicle speed, so as to control the speed and make the vehicle turn to the direction of travel; It's best to skip the first gear. If the speed is still high, you can slow down or jump gears again, because it will be more difficult to jump in second gear, and it will be more dangerous if you fail to jump gear. (3) In the case of effective control of vehicle speed, a flat and wide area should be selected for parking for heat dissipation and maintenance, and the parking brake lever should be tightened after parking.

The brakes fail when going uphill. When the brakes fail when going uphill, you should reduce to the middle and low gear in time to maintain enough power to drive uphill and stop. If you need to stop in the middle of the slope, you should keep the forward low gear, tighten the handbrake, and the attendant should block the wheels with Zen pins stones, skids, etc.

In time. In the event of a roll, the rear of the vehicle should be facing the hillside or the safety side, and the headlights and emergency lights should be turned on to attract the attention of the vehicles in front and behind. Abstract: The most feared thing on the way is that the brakes suddenly fail, and the slightest carelessness may cause the car to be destroyed and killed.

Therefore, if you master the above emergency methods for brake failure, you may be able to save the day and get out of the way. If the brakes fail on a flat surface, just put the oil away, get the steering wheel, and use the handbrake to slowly stop the car. Generally speaking, the problem will not be very big, as long as you don't panic, I believe most of it can be dealt with.

There are many reasons for brake failure, one is the lack of necessary maintenance of the brake system, too many impurities in the brake master cylinder, poor sealing, vacuum booster pump failure, excessive dirt of brake oil or air resistance after the mixed use of several brake fluids, oil leakage of the brake master cylinder or sub-cylinder, air leakage of the gas tank or pipeline interface; The second is the failure of the machine due to improper operation.
