How to solve the problem of soft brakes in the car?

Solve the car brake soft:

1. Brake oil pipe intake.

Brake oil is the medium transmitted by the braking system, if the oil pipe enters the air, the brake fluid under high pressure will appear to be insufficient, although there is still braking force but the maximum braking force is significantly weakened, at this time should be timely to the maintenance enterprise for brake system exhaust treatment.

The way to determine whether the brake hose is intake is to press the brake pedal a few more times until the brake becomes hard in the flame-off state, and then press the brake pedal and hold on, if it has been kept in a hard state, it means that it is normal, and if the pedal sinks slowly, it means that the brake system has taken in.

2. The brake fluid has not been replaced for a long time.

If the brake fluid is not replaced in time, it will contain too much hybrids and moisture, which will affect the transmission of braking force. Therefore, the brake fluid must be replaced regularly, and the moisture content of the brake fluid should be tested in the maintenance company if possible.

3. Oil leakage or the brake material is too soft.

Under normal circumstances, the leakage of the brake master cylinder or brake hose will cause the brakes of the vehicle to become soft, and if the material of the brakes is too soft, the high temperature stability will become poor, which will also cause the brakes of the vehicle to become soft.

The brakes of the car are on the soft side.

Adjustment method:

1. First of all, check whether the brake pads are excessively worn, generally high-end cars are equipped with brake pad wear alarm function, once the brake pad wear is close to the critical value, the corresponding alarm light will be lit on the dashboard;

2. Even if the car does not have this function, when the brake pads are worn to a critical value, the brake disc will come into contact with the metal part reserved by the brake pads, making an abnormal sound, reminding the driver to check and replace the brake pads;

3. Check whether there is internal leakage of the brake master cylinder and sub-cylinder, if the leather bowl inside the main cylinder and sub-cylinder is worn, resulting in pressure leakage, it will cause the feeling of brake softness, which needs to be replaced.

First drive the vehicle to a 4S shop or a professional repair shop to check what causes the brakes to be soft. There are three components of a brake system: brake pads, brake discs, and brake fluid.

1.First, check the brake master cylinder and sub-cylinder for internal leakage. The brake master cylinder is squeezed by several leather bowls through the brake pedal, and the brake fluid transmits the force to the sub-cylinder, and pushes the brake pads to rub against the brake disc to generate braking force.

If the inner bowl of the master and sub cylinders is worn, resulting in pressure leakage, it will cause the brakes to feel soft.

2.Check whether the brake pads are excessively worn, when the brake pads are worn to a critical value, the brake disc will come into contact with the metal part reserved by the brake pads, making an abnormal sound, reminding the driver that the brake pads should be checked and replaced.

3.The brakes become softer and self-adjusting method.

Start the car and wait for the idle speed to stabilize (about 2-3 minutes).

Hit the brakes deep to the end, and be sure to push hard.

After two seconds, pull the handbrake up, and wait for a few seconds without letting go of the foot brake.

Then slowly release the footbrake, and finally release the handbrake.

1. The braking force of the car itself is not good;

2. The brake fluid of the car is insufficient;

3. The brake pads are too thin;

4. The pattern of the tire is gone;

5. The speed is too fast and the inertia is too large.

Some of them are because of pedal problems! Corresponding to the solution can be.

Generally, the brake pads and brake fluid are replaced. Some need to change tires. Some of the pedals are too slippery or too old and need to be replaced with a new one.

To solve the problem of soft brakes in automobiles, the key depends on what causes the brakes to be soft, if the brake pads are too worn, the brake pads should be replaced.

Brake oil into the water, because the brake fluid has a certain hydrophilicity, the car has been driving for a long time, the more water is mixed into it, after the water evaporates, there will be a certain air barrier between the brake pad and the brake disc, so the brake becomes soft and not forceful. In addition, brake discs, brake pads, and tires also play an important role in the braking process. Regularly check the thickness of brake pads and brake discs, and replace them when they reach the wear limit.

If you find that the brake pedal is too soft, you should immediately repair it. The most common solution is to exhaust the brake system, which exhausts the air from the brake fluid at the four brake cylinders, although it cannot completely exhaust the air in the entire pipeline, but can minimize the presence of air. I hope it will be helpful to you, and I hope to adopt it! Thank you!

It may be that the temperature is too high, causing the brake fluid to become thinner and the brakes to become softer, and it is recommended to replace the brake fluid or a higher grade brake fluid when the car cools down and returns to normal.

Analysis of the reasons for the soft brakes of automobiles:

1. Because the brake pads and brake discs will wear out and become thinner and thinner after a long period of use, if you want to brake the car at this time, you need a longer braking stroke, and the braking ability will also decrease, so it will make people feel that the brakes are getting softer and softer;

2. Long-term tire use will also make the tire wear, the tread on the surface of the tire will gradually fade, and it will become what we often call a bald tire, at this time, the adhesion between the tire and the ground will be reduced, because the braking distance has also become longer, so the brake will feel unstoppable;

3. The current brakes mostly use hydraulic braking, so the brake oil is needed to put pressure on the brake pads to achieve the braking effect, friction and heat, the brake pads will produce high temperature when vigorously adding the brake disc, and the high temperature will be transmitted to the brake oil through the brake pads and the brake cylinder.

There are generally two cases when the brakes become stiffer or softer. The first scenario is when the brakes become stiffer or softer. If you are applying the brakes, the brake pads in front are difficult to press, and it is even harder to get down than before.

At this time, it is necessary to pay attention to the fact that there may be a problem with the brake system and it needs to be stopped and sent to the repair shop for repair. On the contrary, the softening of the brakes is not a good sign and may be an oil leak in the car, which also needs the attention of the owner. The second situation is that when you apply the brakes, you will feel the car shaking, and many mountain dust car owners will definitely encounter this situation.

When you apply the brakes, the car will shake or even stall. This is because the car has been driven for a long time and the brake pads have not been replaced, and the owner has to go to the workshop to get a new one. If you insist on applying the brakes, the brakes will fail.

In the third case, the brake pedal is depressed and the brake pedal does not immediately return to its original position. If this is the case, you really need to pay attention, because usually, after pressing the brake pedal, the brake disc wears out. Although the degree of wear is minimal, if it is worn for a long time, the brakes will fail and the engine will be damaged.

Brake fluid needs to be changed regularly. If you don't change it for a long time, there will be a lot of magazines mixed inside, which will affect the braking system, and you will feel that you can't stop when braking. If the brake fluid leaks, it will also affect the braking performance, which may cause brake failure and bring hidden dangers to driving.

There are several ways to solve the problem of too soft brakes. First of all, if the braking distance is extended, it could have stopped, but after stepping on the brake, it did not stop in time, it must be because the brake pads are seriously worn. In this case, you need to stop as soon as possible.

Secondly, weak brakes can also be caused by high tire pressure. At this time, the reduced grip of the tires will also lead to too long braking distances. Finally, a slight reduction in tire pressure can enhance the braking effect of the tire, but the increased friction will also consume more fuel.

Moreover, the side of the tire is under tremendous pressure, which can easily be crushed, and the risk of a puncture is comparable to that of a brake failure. Therefore, tire pressure adjustment needs to be operated in detail according to the standard of the manual and taken seriously.

Summary. Brake hoses, brake pumps.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I'm helping you sort out the answer to your question, please wait a while The brakes are soft, it is possible that you can see if the brake fluid is enough, or whether your vacuum booster drum has air leakage or oil leakage.

I let it off a little bit, and then the brakes were low for a few days.

The reversing image is not displayed, which may be a problem with the camera, or the camera is flooded.

After changing the brake fluid, the brakes worked for a week and the brakes didn't work, what's going on.

No, the depreciation rate of your German car is already high, and if you spend more than 500,000 yuan, I suggest that it is better to buy a new car.

I asked you what the problem was with bad brakes, and what did you pull for me?

Mine is the Buick Micro Blue Hybrid Azure Five.

I'm sorry to rush to Bi, just back to serve others, you drive for a few days and let go a little bit, and the brakes are good, then you may be the brake system where there is oil leakage, and he will be cautious and only enter the air after the oil leakage is wide, you see if there is any air leakage.

So how do you look at it**.

Brake hoses, brake pumps.

It is recommended that you go to the 4S store for on-site inspection and exclusion.

1. There is air in the system, the free clearance is too large, the quality of the brake fluid is poor, the boiling point is low, the bubbles are produced during braking, the main cylinder and the sub-pump are poorly sealed, and the pressure is relieved.

2. Automobile braking system is also known as automobile braking system. The function of the braking system is: to make the moving car force to slow down or even stop according to the driver's requirements; Stable parking of stopped cars in various road conditions, including on ramps; Keep the speed of the car going downhill steady.

3. The brake master cylinder belongs to the automobile braking system, the function is mainly to provide brake assistance, only after the vehicle engine is started, there is a brake assistance effect, buses and trucks and other large vehicles use air pump booster system, small cars use oil pump booster system, the main oil brake brake master cylinder is a vacuum booster pump, in the case of master cylinder assistance, the driver controls the oil pressure of the sub-cylinder when acting on the brake pressure when the brake pedal can be easily stepped on a lot, if the gas vehicle does not start the engine, then use as much as possible, Pressing the brake pedal will not be able to press all the way down.

4. The function of the service brake device is to slow down the moving car or stop in the shortest distance. The function of the parking brake device is to keep the car that has been parked on various road surfaces still. However, sometimes in an emergency, both braking devices can be used at the same time to increase the effect of the car's braking.

Some special-purpose cars and cars that often drive in mountainous areas, long-term and frequent braking will cause the service brake system to overheat, so various types of auxiliary braking devices are often added to these cars to stabilize the speed when going downhill.

Brake softening solution: 1. Start the car and wait for the idle speed to stabilize (about 2-3 minutes). 2. Step on the brakes deeply to the end, and be sure to work hard.

3. After two seconds, pull up the handbrake, and wait for a few seconds until the head and foot brake are not released. 4. Slowly release the foot brake, do not let go of the hand brake. 5. Release the handbrake.

6. Repeat steps 1-5 three times, and you're done.

The brakes of the car ensure our safe driving, and if there is a breakdown, there is no safety guarantee when driving.

Reasons why the brakes of the car become softer:

1. If you don't replace the brake fluid for a long time, the brake fluid is one of the fluids that need to be replaced regularly, if you don't replace it for a long time, there will be many impurities mixed in it, which will affect the braking system and feel that you can't brake when braking.

2. Brake oil leakage, if there is brake oil leakage, it will also affect the braking performance, which may cause brake failure and bring hidden dangers to driving the car.

3. The new brake pads are not run in well, the new brake pads are still in the run-in, and the brake pads that have just been replaced will have a soft feeling.
