What is it like to have bad brakes? What s wrong with a car s brakes not working?

Once I encountered it, the brake pedal completely lost its power, there was no way to press it, the braking effect almost disappeared, fortunately it was on the city road at the time, and the speed was not fast. I could only make a double flash while pressing on the brakes hard, and slowly let the car slip to the side of the road and stop with a little weak braking force.

It was really thrilling, it definitely made people feel the feeling of life and death, and even didn't want to drive anymore for a while, scared.

I was very panicked, once I encountered it, when I stepped on the brake pedal, I felt that the pedal was not raised, there was no resistance, and the car was running far away, which was really scared to death.

I feel very scared, afraid that I will have a car accident like this, and I am afraid that the car will not be able to control and hit a pedestrian, then it will be difficult to escape the blame, but fortunately nothing happened.

I really haven't experienced it, and of course I don't want to experience it, but here we can talk about the brakes, and if the brakes don't work, in addition to the braking system itself (brake discs, brake pads), it may also be related to the grip of the tires used in the car and the road conditions.

I was nervous, I was nervous about the brake system that time, and I was sliding directly on a small slope, but I was scared to death, and I was nervous, but fortunately there was no one.

When driving, the most feared thing is "brake failure", which is a life-threatening thing, if you don't get it right, you can really have a car accident.

I once had the brakes of the car fail, and the pedals didn't work, and I felt like I was in a cold sweat in less than a minute.

At that moment, I really felt helpless, I couldn't escape, so I just slid with the car, fortunately I didn't run into anyone, otherwise I would have died of guilt.

8 years ago, the driver's license test was used to practice a broken pickup truck with ineffective brakes, the brakes on the road practice car are not working, the coach scolded the half-dead said that the brakes are not working on a few more feet, from where to start to develop a habit, 8 years I stepped on the brakes have not stepped on the end of the foot.

I feel that my car brakes can't be braked, and I always have to press hard to have a little effect, and now it has been sent to the 4S store.

1. Serious overload: The vehicle is seriously overloaded, and under the action of gravitational acceleration, the inertia of the vehicle movement is increased, which directly leads to brake failure.

2. Improper operation:Due to improper operation, the failure of the parts, such as a long downhill slope, will cause the brake pads to rub and generate heat, the brake hub to carbonize, and the brake function to completely fail.

3. Weather factors:In summer, many car owners will find that the brakes are very difficult to press, because most cars turn on air conditioning in summer, which is easy to increase the load of the engine, and ultimately affect the play of the brakes.

Precautions for novices to step on the brakes.

When you don't step on the accelerator, your foot must be on the brake, don't be too troublesome, you must not put your foot on the accelerator, and avoid subconsciously stepping on the pedal in an emergency.

If you want to stop, you must stop: you need to practice deliberately. Take time to ask someone to accompany you to practice, and when you are on guard, the person in the same car suddenly shouts: stop, and forms a conditioned reflex under repeated reinforcement. Avoid the possibility of wrong stepping in an emergency.

First, the handbrake line is tight and does not return.

The direct consequence is that the brake disc is overheated, or the brake noise is abnormal, and the brake pad is overheated and the thermal attenuation occurs, and the brake thermal attenuation is one of the main culprits of brake failure.

Second, the brake master cylinder inlet air.

Exhaust is very important when changing the brake fluid, if the air in the brake fluid is not excluded, it will have a serious impact on the braking effect, and even cause brake failure. If the brake master cylinder enters the air and the brake becomes softer, there may be no brake response when the brake is pressed to the end, and it is necessary to count the brakes to have a certain effect. When the brake master cylinder enters the air, it needs to be discharged immediately and the cause should be found, if the brake master cylinder fails, there will be endless air discharge.

3. The hidden danger of long-term braking caused by too high brake oil and water content.

The water content in the brake fluid can be detected by the brake fluid inspection pen, and once the water content in the brake fluid exceeds the standard, it is also a manifestation of the deterioration of the brake fluid. Brake fluid also needs to be serviced and replaced regularly, especially if there is too much water.

Fourth, the brake failure caused by the failure of the brake master cylinder.

The failure of the brake master cylinder is a serious fault problem, and the fault is mostly manifested in the internal leakage of the pressure of the master cylinder, the brake pedal is empty, and the brake pedal is lower than the other, and even the brake force is not there when the brake pedal is empty.

1. The gap between the brake pads and the wheel hub;

2. The brake pads are seriously worn, and the shoe clearance adjustment is not suitable;

3. There may be problems with the vacuum booster pump and lack of brake fluid;

It is recommended that you go to a 4S shop or a large repair shop to check it, because the brake system has great safety hazards.

Hope it helps!

1. Improper operation.

Due to the improper operation of the brakes in daily driving, the failure of the parts, such as a long time downhill, the brake pads will be heated by friction, the brake hub will be carbonized, and the brake function will be completely invalid.

2. Lack of maintenance.

In daily maintenance, the lack of necessary maintenance of the brake system, too many impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, excessive dirt of the brake fluid or the mixing of several brake fluids after heating, oil leakage of the brake master cylinder or sub-cylinder, air leakage of the air tank or pipeline interface and other problems will lead to brake failure.

3. Serious overload.

Due to the serious overload of the car when driving, under the action of gravitational acceleration, the inertia of the vehicle movement is increased, which directly leads to brake failure.

Check whether the brake pads and brake discs are normal, check the brake fluid, check the brake vacuum booster and vacuum tube, it is also possible that the braking time is too long, resulting in a decrease in the friction coefficient, which will make the brakes insensitive. If you're not too professional, it's best to go to a repair shop. Hope to adopt!

The braking effect is significantly reduced, often the brakes are stepped on and can not be stopped immediately, and continue to walk far forward to stop, this may be the car's braking system failure, this is the most terrible fault in driving, often easy to form traffic accidents, to do emergency treatment, generally to see whether the brake pads are aging, whether the brake fluid is deteriorated, whether the tires are seriously worn.

What should I do if the brakes of the car are not working? Don't be in a hurry, the old driver will teach you to solve it easily!

What's the deal with the car not working? I wonder what you guys think? Let's talk about it.

What is going on with the brakes are not working, the reasons why the oil brake rents the front car can not brake: 1. Daily operation errors, most of the reasons are the daily operation and maintenance errors of the car owner, because the owner must regularly maintain the braking system of the vehicle, once the braking problem can not be underestimated, it must be checked clearly in the vehicle 4S shop; 2. The car is overloaded, many car owners will find that it is not good to step on the brakes in summer, the reason is that most cars will have air conditioning in summer, if the displacement of the car is not large, it is easy to increase the load of the engine, and ultimately affect the play of the brakes; 3. Weather factors, the brake brake is not firm, which is the case for many car owners when using the brakes, especially for small displacement cars, because the engine power is not enough, and when the air conditioning is turned on, the power pump can not play its due role when the car owner repeats the braking process. @2019

1. When you find that the brake system is out of order, don't panic, because once you panic, it is easy to make mistakes. If you press the brakes as the accelerator, it will only make the situation worse. So be sure to calm down and adjust your mindset.

Since it has happened, we must find a way to save ourselves and minimize the loss. Use the handbrake wisely to control the vehicle. If you find that the brakes are out of order if you encounter a continuous downhill section or a steep downhill section, try pulling the handbrake first to see if you can stop the vehicle.

2. When pulling the handbrake, be careful not to pull the end or pull too fast, which is easy to cause damage and failure of the handbrake. You should slowly pull the hand brake all the way down. Downshift appropriately to control vehicle speed.

If the handbrake slows down or the handbrake fails, you should try to use the Songtong method of forced downshift (commonly known as gear grabbing), use the low gear to reduce the speed of the car, and then use the handbrake to brake the car slowly.

There are two situations discussed here, one is the vehicle without the ABS anti-lock braking system, and the old vehicles are basically like this. When this kind of vehicle encounters emergency braking, if the braking force is too large, it may make the car tires lock (the tires do not rotate at all), we can often see two long black brake marks on the road, which is the traces of friction between the tires and the ground when the car brakes without ABS, the axle tires will no longer rotate after the tires are locked due to emergency braking, but the huge inertia will make the tires of the car rub against the ground and continue to slide forward, The violent friction between the tire and the ground caused the rubber particles on the tire to rub and sell, resulting in a black mark. At this time, if you force the direction, it will often have serious consequences such as deviation, side slippage, tail flicking, or even rollover out of control.

The braking system is generally composed of two main parts: the brake control mechanism and the brake. The brake control mechanism produces the braking action, controls the braking effect, and transmits the braking energy to the various parts of the braking system, and the brake is the part that generates the force that hinders the movement or movement trend of the vehicle.

1. The brake pads are seriously worn, the brake pads are divided into two kinds with induction lines and without induction wires, and when the brake pads are worn to the limit position, the induction line will automatically connect to the circuit, and then the fault light will be lit. Brake pads need to be replaced;

2. The brake fluid level is too low, and the lack of brake fluid will be accompanied by an obvious lack of braking force, and even the loss of braking force will occur in serious cases. In this case, the warning light will turn on. As long as the brake fluid is replenished in time;

3. Oil leakage and false alarm of the brake system. It directly affects the technical performance of the car, resulting in the waste of lubricating oil and fuel, consuming power, affecting the cleanliness of the car, and causing environmental pollution. The fault light will be lit and the gasket or oil seal needs to be replaced.

If the braking system fails, it will affect the driving safety, and it is necessary to check and repair it in time. The braking system of the automobile is composed of a vacuum booster pump, a brake master cylinder, a brake cylinder, a brake pad, and a brake disc. In order to ensure the safe driving of automobiles, increase the average driving speed of automobiles, and improve transportation productivity, special braking mechanisms are provided on various automobiles, and such a series of specialized devices are called braking systems.

The main function of the braking system is to slow down or even stop the moving car, to stabilize the speed of the car driving downhill, and to keep the stopped car still.

Immediately, immediately go to repair, the brake is not working is a major safety hazard.

There are three reasons for the occasional brake failure of a car: the first is the failure of the brake system caused by poor maintenance of the brake system, the second is the failure of mechanical components caused by improper operation, and the third is the failure of the brake system caused by the overload of the vehicle. If the braking system is not maintained in daily use, there are too many impurities in the brake master cylinder and the sealing is not tight, which makes the braking system temporarily fail.

In addition, faulty vacuum booster pumps and unclean brake fluid can also cause brake failures. In addition, improper operation can also lead to brake failure. For example, a long downhill period can cause the brakes to temporarily fail.

If the vehicle is overloaded, the braking distance will be shortened, so the brakes will fail for a short time.

The reasons for the insensitive brakes are: 1. The first reason is that the thickness of the brake pads and brake discs is thinner due to the wear. For example, disc brake calipers (also known as brake pads) clamp the brake disc for a long time, and friction will make the surface of the caliper and brake disc become thinner and thinner, which will make the travel side of the brake pedal longer; 2. The second reason is the wear and tear of the tires.

The life of the tire is generally about 60,000 kilometers, and the tread of the tire will be ground very thin, reaching the wear mark in the tire groove. The adhesion between the tire and the ground will also deteriorate due to long-term friction, resulting in a long braking distance between the braking distance; 3. The third and most important reason is the problem of brake fluid. At present, the braking system of most cars is hydraulic braking, which requires the pressurization of brake oil to transmit this braking force to the brake pads.

The volume of brake fluid is not easy to decrease after being compressed. However, friction generates heat, and this brake pad will produce high temperature when the brake disc is vigorously applied, and the high temperature will be transmitted to the brake fluid through the brake pad and brake cylinder.

Driving a car requires braking. Once the brakes fail, it can be said that there is a serious safety hazard to the people in the car. So what do we do when the brakes fail?

First, let's look at the causes of brake failure:

1.Oil leakage, abrasion, clogging, etc. Occurs in the brake master cylinder and wheel cylinder.

2.Deterioration of brake fluid or excessive dirt in the line.

3.Improper clearance between the brake drum and the brake shoe leads to abnormal movement of the hidden liquid head during braking.

These are all problems caused by car breakdowns. If you encounter this situation, you should go to the repair point in time to check.

Of course, in addition to the breakdown, it is also possible that the car is overloaded. If the weight of the car exceeds a certain range, the performance of the whole car will be reduced, so when the brakes are not good, we can first try to remove the excess items in the car and bury them, and then try again.

It may also be that the tire grip is not strong, the car mainly relies on the tire to contact the ground, and the brake is also achieved by the friction of the tire, so if the tire is not good, it will also affect the performance of the car.

Emergency treatment methods for brake failure during driving.

Pulling the brakes can gradually reduce the speed of the car or it can be achieved by lowering the speed gear of the car. When there is a failure such as uphill, we can slow down into the middle and low gear, so that it has enough stove power to stop the uphill gear, and then switch to the low gear halfway uphill, and finally tighten the handbrake to block the movement of the main wheel with obstacles such as stones.
