When the brakes are applied, the ABS is empty after starting, what s going on

ABS (Anti-lock braking system) anti-lock braking system, through the sensor installed on the wheel to send a signal that the wheel will be locked, the controller instructs the regulator to reduce the oil pressure of the wheel brake cylinder, reduce the braking torque, after a certain period of time, and then restore the original oil pressure, continuous such cycle (up to 5 10 times per second), always make the wheel in a rotating state and have the maximum braking torque.

The car without ABS is installed, if the brake pedal is pressed hard while driving, the wheel speed will decrease rapidly, when the braking force exceeds the friction between the wheel and the ground, the wheel will be locked, the wheel will be locked up completely, the friction between the tire and the ground will decrease, if the front wheel is locked, the driver can not control the direction of the vehicle, if the rear wheel is locked, it is very easy to slip sideways.

ABS, which was originally applied to the technology of aircraft, is now very popular, and it can be seen in cars of more than 100,000 yuan, and some buses are also equipped with ABS. Vehicles equipped with ABS can safely operate the steering wheel and brake on slippery roads such as snow, ice, or rain. It not only effectively prevents accidents, but also reduces the wear and tear on the tires, but it does not make the car shorten the braking distance, and in some cases it increases.

Tips: In case of emergency, the brake pedal must be pressed to the end to activate the ABS system, at this time the brake pedal will have some shaking, sometimes there will be some sound, but it can not be released, which indicates that the ABS system is starting to work.

Solved the ** thing.

The ABS system only works when the vehicle is driving at high speed, parking or slow driving does not work, the start you say is that the brakes cannot be stepped on when the car starts, it may be a problem with your braking system, not a problem with the ABS system.

As long as you don't release the brake pedal, it will not stop working until the car comes to a stop [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, the pump is working, you just need to press the brake tightly, don't put it, it will automatically brake, similar to point kill, computer-controlled, very fast, the pedal has the feeling of springing feet, this is to prevent the wheels from locking up [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Dear, hello, when the ABS brake of the vehicle is explosion-proof, if the brake cannot be stepped on after the system is started, it is necessary to release the brake and step on the brake again. Maintain the continuous braking performance of the vehicle to bring the vehicle to a faster stop.

First, after the ABS anti-lock braking system is activated, if it is in a state of fast driving, it is okay to directly press the brakes on the premise of keeping the vehicle in a straight line.

Second, if it is on an ice and snow road, after this mining, it is obvious that the feet are spring, and then it cannot be stepped on, in this case, you can release the brakes and step on it again, or continuously and intermittently step on the brakes to make the vehicle brake faster.

How to solve the problem that the brakes cannot be stepped on after the ABS brake anti-lock system of the car is activated? Do you let go of the brakes and apply them again, or what should you do?

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, dear, car master exclusive technician for you service, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this service helpful. If it helps you, we look forward to your likes and attention.

I wish you a happy New Year's Day, hello, when the vehicle or the ABS brake explosion-proof, if the brake cannot be stepped on after the system starts, it is necessary to release the brake and step on the brake again. Maintain the performance of the vehicle to continue braking, in order to make the vehicle brake first, after the ABS anti-lock braking system is started, if it is in a state of fast driving, this is in the premise of the brother guessing the vehicle to drive in a straight line, directly stepping on the brakes is also the second envy type, if it is on the ice and snow road, after this mining, obvious spring, and then do not move, in this case, you can let go of the brakes, and then step on again, or continuous intermittent step on the brakes, so that the vehicle brakes faster.

If you rule out the road surface and tire problems, check the braking system of the lower four wheels, turn off the ABS computer, and then find four people to help see which of the four wheels locks up first when braking. Then there is whether the wheel speed sensor of the four wheels is pasted to death by the brake pad powder.

ABS anti-lock braking system, through the sensor installed on the wheel to send a signal that the wheel will be locked, the controller directs the regulator to reduce the oil pressure of the wheel brake cylinder, reduce the braking torque, after a certain period of time, and then restore the original oil pressure, continuous such cycle (up to 5 10 times per second), always make the wheel in a rotating state and have the maximum braking torque.

In a car without ABS, if the brake pedal is pressed hard while driving, the wheel speed will decrease rapidly, and when the braking force exceeds the friction between the wheel and the ground, the wheel will be locked.

Fully locked wheels reduce the friction between the tires and the ground, if the front wheels are locked, the driver cannot control the direction of the vehicle, and if the rear wheels are locked, it is extremely prone to side skidding.

In case of emergency, the brake pedal must be pressed to the end to activate the ABS system, at this time the brake pedal will have some shaking, sometimes there will be some sound, but it cannot be released, which indicates that the ABS system is starting to work.

Addendum: The development of the ABS system dates back to the early 20th century. In the late 70s of the 20th century, the rapid development of digital electronic technology and large-scale integrated circuits laid a technical foundation for the practical development of ABS system, and many companies have developed various forms of ABS system.

Since the mid-80s of the 20th century, the ABS system has developed in the direction of high cost performance. Some companies have simplified the structure and optimized the system of ABS, and launched an economical ABS device; Some companies have introduced rear-wheel ABS or four-wheel ABS systems for light trucks and passenger and cargo vehicles.

These efforts have created the conditions for the rapid popularization of ABS. The ABS system is considered to be the most important technical achievement in terms of safety since the introduction of seat belts in automobiles.

The above content refers to the anti-lock braking system - encyclopedia.

It is normal for the car ABS to feel that the brakes are bumpy and cannot be stepped on when the brakes are stepped on, because the ABS function of the car is the role of auxiliary braking.

If the ABS system fails, the rest of the safety system will also lose its effect, the braking ability of the car will be greatly reduced, and the control ability of the body will also be sharply weakened, and the car will be in danger of losing control in an emergency. When the ABS system of the car fails, it is necessary to go to the repair shop for repair as soon as possible to avoid a bigger failure.

When the ABS light on the car is on, it means that the ABS system has failed. At this time, the braking performance of the car will decline, and if it is not repaired, it will greatly affect the driving safety.

If it is not normal, the reasons and solutions for stepping on the brakes ABS light are as follows

1. The ABS light is always on, indicating the alarm of the anti-lock braking system. Under normal circumstances, the light will turn on when the ignition switch is turned on or the engine is started, and the system enters the automatic detection program, and after the detection is completed, the light is turned off. If the light does not turn on after turning on the ignition switch, or does not go off after it is on, or lights up while driving, it indicates that the system is faulty.

2. There are two possibilities, if only the ABS warning light is on while driving, it means that there is a fault in the ABS system, but the car is still reliable in the conventional braking system, and the professional should be asked to repair it with a diagnostic instrument as soon as possible, judging that it is a problem such as gear ring, sensor, and line; If the ABS warning light and the braking system warning light are lit at the same time while driving, it means that both the ABS and the braking system are faulty, and the braking characteristics will change.

If the latter is the case, you must immediately stop driving and check the brake fluid level. If the liquid level is normal, it indicates that the ABS system may fail, that is, the adjustment function of the ABS system fails, and only the ordinary braking system plays a role, which is easy to cause the rear wheels to lock up quickly when braking, resulting in side skidding. At this time, you should drive with caution and carry out repairs as soon as possible.

Precautions for driving:

1. Fasten your seatbelt. The first thing to do when you get in the car is to fasten your seatbelt, and don't forget to remind your family or friends to wear one.

2. Check the condition of the car regularly. In a timely manner, the vehicle has been regularly maintained, and it is necessary to check the condition of the vehicle frequently, see whether the parts, tires, lights, oil, etc. are running well, and repair the problems in time.

3. It is strictly forbidden to run red lights. I believe everyone knows this, now that the traffic laws are strict, the punishment for running a red light has been increased, and very few people run a red light, but you must know that the purpose of doing so is nothing more than to ensure safety.

4. Don't overtake casually. Don't try to overtake to save a little time, especially if you're following behind a big car and obstructing the view ahead, as overtaking is most dangerous because you can't be sure if there's a car coming from the opposite side.
