The pros and cons of sudden death of automobile brakes, and what are the general causes of sudden de

Now the general car basically has to have anti-locking, mainly for safety considerations, the wheel is dead, it freezes, can not turn to dodge. It is dangerous at high speeds.

If the car is not equipped with ABS, if the brakes are pressed too hard while driving, the wheels will rapidly reduce the rotational speed, and if the braking force exceeds the friction between the tires and the ground, the brakes will lock.

Here's what causes brake locking

1. If the car without ABS is installed, if you press the brake pedal 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, and the completely locked wheel will reduce the friction between the tire and the ground, and in serious cases, there will be dangerous phenomena such as side sliding, tail flicking and sharp turn. So it's best to take this into account when buying a car;

2. To put it simply, even if you don't step on the brake pedal, you still obviously feel that the car resistance is large, and in serious cases, you will make abnormal noises or even lock the wheels. If the brake fluid is not changed for a long time, resulting in the internal rust of the brake cylinder, it can be repaired by sandpaper sanding and buttering; If the sub-pump itself is faulty, it is likely to be replaced directly;

3. Generally, water or other impurities in the braking system, or the system is not cleaned before replacing other grades of brake fluid, resulting in the bubble of the leather bowl of the brake master cylinder causing locking, this kind of problem is not a design problem, it is caused by wrong operation, and the solution to this problem is to clean the entire braking system and replace the leather bowl of the brake master cylinder.

If the front wheels are locked, the car will not be able to steer, and the steering of the car is based on the front wheels, which is easy to cause accidents due to inertia sliding forward. If the rear wheel is locked, it will slip sideways, which is also a very dangerous situation. Therefore, brake locking is mainly caused by stepping on the brake suddenly, and daily driving should avoid sudden braking to eliminate the source of wheel locking.

In addition, the installation of ABS system can effectively prevent wheel locking, which is now the anti-lock braking system that most cars will install.

The vehicle has brake locking, tire locking, brake not returning and other faults, generally due to the following reasons: 1. The air pressure of the vehicle is insufficient; 2. The air valves are blocked; 3. Air leakage of brake cylinder; 4. Rust of brake shoe pins.

Brake locking means that the wheels stop rotating after being subjected to strong braking force, and due to the inertia generated by the speed of the vehicle, even if the wheels do not turn, the car is still sliding forward. In order to solve this problem, automotive engineers use ABS anti-lock braking technology, the main feature of this technology is that after pressing the brakes sharply in an emergency, the wheels will not stop rotating, which will ensure that the vehicle and the ground are not sliding friction, can ensure that the vehicle will not lose control, and the tires will not burst due to sliding friction.

The car without ABS is installed, if you press the brake pedal 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, and the completely locked wheel will reduce the friction between the tire and the ground, and in serious cases, there will be dangerous phenomena such as side sliding, tail flicking and sharp turning. So it's best to take this into account when buying a car;

Tyre locking is when the brakes (whether disc or hub) tighten the tyre, and the tyre has no relative motion towards the brake.

In other words, the tires don't turn and the car slides like a brick on the road.

If you lock up on the brakes, it is a failure of the brake cylinder or master cylinder. If you don't lock on the brakes, it may be that the fixing pin of the brake pad falls off, causing the brake pad to be misaligned and the brake disc is locked.

First, the brake cylinder of a certain wheel is not well returned, and the thermal expansion effect is easy to occur during driving.

Second, the gap between the ejector rod of the vacuum booster and the brake master cylinder is not properly adjusted, which affects the oil return of the system, and the gap between the brake pad and the brake disc is too small after a few feet of braking, and the semi-braking situation occurs during the driving process, and the continuation time is slightly longer, and the brake is easy to lock under the action of thermal expansion.

However, frequent sudden braking is also harmful to the vehicle. The main hazards of long-term sudden braking: 1. It mainly affects the service life of tires and increases wear; 2. Reduce the service life of the engine; 3. Reduce the service life of the clutch system; 4. Increase fuel consumption; 5. Increase the service life of brake pads and brake discs; 6. Accelerate the aging of the brake cylinder and the brake master cylinder.

> if you only press the brake pedal, then the braking force for the vehicle needs to overcome two aspects, one is the kinetic energy of the car itself, and the other is the traction of the engine.

If the brake pedal and the clutch pedal are pressed together, the torque output of the output shaft of the engine has been separated from the transmission shaft during the braking process, and the braking force does not need to overcome the traction of the engine while overcoming the kinetic energy of the car itself, and the braking distance will be shortened. (Not necessarily applicable to braking on downhill slopes).

It has a great impact on tire wear; The service life of the engine will be reduced; The clutch system will also be lowered.

In the process of driving a car in our daily life, the most instinctive reaction in an emergency is to step on the brakes, and it is very dangerous to brake sharply when the speed is too high, and the sudden braking will also have a certain harm to the car itself. So specifically, what are the effects of hard braking on the car?

First of all, it is the impact on car tires and brake pads. When the speed is too high, the inertia and weight of the vehicle will all act on the tire, which will lead to increased friction between the tire and the ground, which can easily cause serious wear of the tire.

The sudden increase in friction between the brake pads and the brake disc during sudden braking will also cause serious wear of the brake pads, and the service life of the brake pads and tires will be shortened for a long time, which will bring hidden dangers to driving safety.

Secondly, it is the impact on the suspension system of the car. The suspension system of the car is the connecting device between the frame and the axle of the car, which can play a role in mitigating the impact force and ensuring that the car drives relatively smoothly.

Generally speaking, the suspension system will have springs and shock absorbers and other devices, which can play a shock-absorbing effect. When braking suddenly, the center of gravity of the car moves forward due to the action of inertia, and the suspension system at this time will affect the elasticity and cushioning force due to excessive compression, if this goes on for a long time, the suspension system and the body need to bear all the impact force, and it is easy to twist or even deform.

Finally, there is the impact on the performance of the car's engine. In the process of driving, sudden braking or sudden acceleration will cause the engine speed to change too quickly, and the fuel in the combustion chamber will not be fully burned, and carbon deposits will be generated.

If there is too much carbon deposit, the engine will have problems such as insufficient power, strong shaking, shortened life, and increased fuel consumption.

To sum up, sudden braking still has a certain impact on the performance of the car. Although the occasional sudden braking is not a big problem, if you develop the habit of sudden braking, it is very detrimental to both the car itself and the safety of the driver. Therefore, it is also recommended that friends must pay attention to the smoothness of power output in the process of driving a car to avoid sudden braking or rapid acceleration.

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

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Questions. Hard braking is a rattle of the brake pedal, do you need to check the braking system?

My car used to brake when it was lightly pressed on the brakes and it would automatically go down, and what happened when I felt wrong after the car was in a hurry.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! According to the information you provide, the brake pads are damaged by the sudden braking, which has a great impact on the braking system. Sudden braking also accelerates the wear and tear of the car's tires, which can reduce the life of the tires.

2. Rapid acceleration makes the load of the car increase suddenly, increases the burden on the engine and transmission, damages the engine and transmission system, and affects the life of the engine. 3. Sudden braking has a damaging effect on the engine, gearbox and brakes, affecting the service life of these parts. Just like a person who suddenly runs with force, it will cause damage to various organs.

4. Fuel consumption will also increase, the loss of the brake system will be great, the brake disc and brake pads will be replaced earlier, the clutch system will also reduce the service life, and the brake cylinder and brake master cylinder will be damaged relatively quickly. 5. It will aggravate the wear and tear of the suspension system and brake system. In short, sudden braking is very damaging to the car, and there is nothing wrong with an occasional sudden braking, and often, the service life of the car engine will definitely be shortened.

Second, emergency braking should also pay attention to the hidden danger of rear-end collision, this situation is common in urban driving, if the front car emergency stop, then after the emergency braking, as far as possible to slow down the brakes, so that the car slipped forward, leaving room for the rear car to buffer, otherwise you are stopped, but the rear car is afraid that only by hitting you to force yourself to stop.

Is it normal to pay attention to the gurgling sound of sudden braking?2021-12-25 14:39It is normal to pay attention to the gurgling sound of sudden braking. This is the sound that the ABS anti-lock braking system makes when it is activated.

Most cars are equipped with ABS anti-lock braking systems, which prevent wheel locking in the event of emergency braking. If you die holding the wheels during emergency braking, the car will skid and lose control, and the driver will not be able to slow down the car or control the trajectory of the car, which is very dangerous. The ABS anti-lock braking system keeps the wheels rolling and slipping during emergency braking, so that the driver can use the steering wheel to control the vehicle's trajectory while decelerating.

When driving a car equipped with ABS system, the correct operation in case of emergency is to press the brake pedal all the way down, which will trigger the ABS system.

Questions. Once in a while, it's not a big deal.

My car used to brake when it was lightly pressed on the brakes and it would automatically go down, and what happened when I felt wrong after the car was in a hurry.

In recent years, the number of cars in China has been increasing, everyone's love for cars has become stronger, and the traffic pressure is increasing, which has also made the traffic management department launch a series of traffic policies to deal with it. The main purpose of traffic rules is to restrain the driving behavior of drivers, and to reduce the incidence of traffic accidents by avoiding bad habits of driving, which will also ensure everyone's safety.

Most of the drivers have developed good driving habits, and the violation rate and traffic accident rate are decreasing year by year, but there are still some drivers whose driving behavior has become a habit, and they do not think that their driving habits will cause danger. The braking system is one of the most important systems of the car, the quality of the braking system is directly related to the life safety of passengers in the car, some drivers like to brake suddenly, which is a wrong behavior.

The damage of the sudden braking to the car is very large, the most direct manifestation is that the sudden braking will cause serious wear and tear of the tires and brake pads, and the vehicle will also constitute a huge impact on the overall vehicle structure because of the huge inertia, and the sudden braking will also have a strong impact on the automobile chassis suspension system when driving at high speed, and the internal parts will be deformed and damaged in serious cases. When the driver brakes suddenly, the tires will also be severely worn out from the ground, which can cause huge damage to the tires.

In severe cases, the tires will also produce high temperatures due to high-speed wear, which will lead to tire punctures, which is fatal for vehicles that are driving at high speeds, and the problem of loss of direction of the vehicle will also threaten the safety of the people in the car. After braking suddenly, the vehicle will have a lot of inertia, which is better for the front passengers, after all, there is seat belt protection, and the rear passengers are not necessarily so lucky, and it is normal to fly out of the car when the speed is fast enough.

Comments: Think that emergency braking is a vice, we must avoid this wrong braking method, the normal braking method is point brake or slow brake, so that not only the passengers in the car will have a comfortable driving experience, safety is also very guaranteed. The braking system is very important, it is recommended that the majority of car owners can check the brakes in their spare time, regular maintenance, and life safety is the first place when driving.

The disadvantages of the car's sudden braking are mainly due to the greater impact on tire wear, the service life of the engine will be reduced, the clutch system will also reduce the service life, the fuel consumption will also increase, the brake system will be greatly damaged, the brake disc brake pads will be replaced earlier, the brake cylinder, the brake master cylinder will be damaged relatively quickly, which will seriously affect the service life of the vehicle, it is recommended not to drive like this.

Yes, as follows: the impact on tire wear is relatively large;

The service life of the engine will be reduced;

The clutch system will also reduce the service life;

Fuel consumption will increase;

The loss of the brake system will be large, and the brake disc and brake pads will be replaced relatively early;

Brake cylinders, brake master cylinders, damage will be relatively fast.

Brake pads. It is the most critical safety part of the car, and it is one of the most frequently used parts in the braking system of the car and in daily driving, and regular maintenance is essential. When driving, you should be careful not to brake too often, as it will cause great damage to the car.

Brake pads need to pay attention to daily maintenance, mainly regular inspection, pay attention to the thickness of brake pads, and replace brake pads in time. In short, sudden braking and rapid acceleration have a great impact on the car and seriously affect the service life of the vehicle, but in case of emergency, do not be stingy with your brake pads.
