The brakes of the car are very soft, and you can only brake when you step on low?

It's possible that the air isn't running out. If it is not a problem of air, it is necessary to see that the oil in the brake oil pot is a lot, if it is less, it must be that the brake booster pump is broken, and the oil in the oil pot must not be a pipeline leakage.

There are several that may cause this phenomenon, first check the use time of the brake pads, if the use time is long, the brake pads can be replaced if the brake pads are overly frosted, and check whether the brake master cylinder and the sub-cylinder have oil leakage, if the oil leakage is found to need to be repaired or replaced, and then used, and finally check whether there is brake oil, or there is air in the oil circuit, you can replace the brake fluid to solve the problem.

There are three possibilities for you, the first possibility is that the brake pads are running out.

Second, you may also be in this situation if you are missing brake fluid.

Thirdly, a leak of a brake pump can also occur.

If the brakes are soft, it means that there is air in the line that is not being discharged, or the brake pads are badly worn, resulting in insufficient brake fluid.

First of all, check the wear of the brake pads and vent the pipeline.

The brakes of the car are very soft, and you can only brake when you step on it to the end, what's going on? In the end, it can be braked, which means that your brake pads are no longer good and must be replaced in time.

In this case, it is very likely that the travel distance of your brake is too far, and you must adjust it in time, otherwise it is easy to have a traffic accident in the later stage, and you must pay attention to it.

If it is normal before, you should check the brake pads and brake fluid.

It may be because the brake disc of the original car has been worn, and the new brake pads and the brake disc have not yet fully contacted, resulting in the problem that the brakes have become soft, and you have to step on it very deep to brake. Maintenance method of brake pads.

Under normal driving conditions, every 5000 kilometers of the brake shoe is inspected, not only to check the remaining thickness, but also to check the state of the shoe wear, whether the degree of wear on both sides is the same, whether the return is free, etc., and the abnormal situation must be dealt with immediately.

Brake shoes are generally composed of two parts: iron lining plate and friction material, and you must not wait for the friction material part to wear out before replacing the shoes.

When replacing, the brake pads provided by the original spare parts should be replaced, only in this way can the braking effect between the brake pads and the brake disc be the best and the wear and tear should be minimal.

After replacement, be sure to step on the brake a few times to eliminate the gap between the shoe and the brake disc, resulting in the first foot without braking, which is prone to accidents.

First, the oil is not enough, check and replenish. The second is oil and air, it is recommended to go to the repair shop for inspection and treatment. The third is that there is a problem with the pump.

Check whether the brake cylinder is rusty, if it is rusty and needs to be repaired, or it may be caused by the total brake scale of the vehicle or the oil leakage of the brake hose.

If the braking distance is extended, consider replacing the brake fluid or see if the brake pad wear is serious, you can also adjust the stroke to see if it is not so soft, and it is not other problems to brake.

You can find a master to adjust the itinerary or go to the maintenance department to ask the master to see, basically for these reasons.

I feel like you're talking about the air brake on the truck, which is normal, because there will be air resistance in the pipe, and the solution is to just step on it a few more times; If it is a car, check whether there is a problem with the brake fluid and brake pump and brake oil pipe, and try to solve it as soon as possible, after all, safety is not a trivial matter.

1. There is air entering the brake system;

2. There is a large free gap in the braking system;

3. Poor quality inspection of brake fluid for vehicle acceleration;

4. The sealing performance of the main pump and the sub-pump is not good;

5. Different brands or different types of brake fluid are added to the vehicle, resulting in pressure relief from the master pump and sub-cylinder.

Hello, there are several reasons: 1. There is air in the brake oil can. If you have just changed the brake fluid, then it is very likely that the master did not help you drain the air in the brake line, and the air in the pipe will make the vehicle brake weak and weak; 2. The brake pads are seriously worn. When the brake pads are worn, the overall thickness will become thinner, so the driver needs to press the brakes deeply to achieve the original braking effect; 3. Insufficient brake fluid.

You can check whether the brake fluid level in the brake oil pot is between the max and min scales, if the brake fluid is lower than the min scale value, it proves that the brake fluid is insufficient. It is recommended to find a professional to repair and deal with it!

There are two reasons for this. 1. There is gas in the pipeline. The phenomenon is that the brakes are applied twice, but the first foot feels soft.

2.The slice is thin. The phenomenon is which foot brake is lost.

But the braking distance has changed compared to before Whatever the reason, it must be repaired in time, after all, braking is related to life.

There are four possibilities for soft brakes, the first is that the brake fluid cannot establish oil pressure to the limit of use, and it needs to be replaced. The second is that there is air in the brake fluid and it needs to be exhausted. The third is that the brake fluid has too much moisture content and needs to be replaced. The fourth is that the brake fluid is insufficient and needs to be added.

This situation is generally caused by the aging of the leather bowl of the brake master cylinder, and it should be replaced in time, otherwise it will be dangerous!

Check if the brake fluid is missing, add. Then check whether there is air in the brake system, the air in the pipe needs to be removed, and then the brake pump is faulty and needs to be repaired or replaced.

The brake soft foot is very dangerous and needs to be repaired in time, first check whether the brake fluid is missing and deteriorated, replace the brake fluid, check whether the brake shoe is seriously worn, if it is seriously replaced, it is not good to make it necessary to check the clutch master cylinder and sub-cylinder, whether the sealing ring and the leather bowl are damaged, and replace it.

It shows that the brake pads of the car are too worn out and need to be replaced.

1. Car beauty and decoration mainly learn car beauty and decoration, mainly learn to clean and clean the car, and also paint the car decoration film.

2. The solid wood floor must be seen at the decoration manufacturer or store site, and it must also see whether its solid wood is real solid wood.

3. All online loans cannot be loaned, they are all deceptive, they are illegal, and they are all subject to credit investigation.

The car brake system is very important, it is often checked and replaced for maintenance, and you can go to the car repair shop or 4S shop to repair the brake soft. It's safer to drive this way.

See if the brake fluid is enough.

Weak brakes and abnormally weakened braking force are usually three conditions that cause this result.

1. The oil pressure of the sub-pump or the main pump is not good, and there may be oil leakage;

2. There is air in the brake line, assuming that the pedal height increases slightly when braking a few feet in succession, and there is a spring**;

3. Brake faults, such as brake pads, brake discs, etc.

There are a variety of problems that arise:1It is the vehicle's tires that are overworn, and the tires need to be replaced.

2.The brake pads of the vehicle are excessive and need to be replaced. 3.

The vehicle's brake oil is up to the time to change. 4.The vehicle's ABS sensor is faulty and needs to be inspected or replaced.

The brake of motor vehicle mainly relies on the intense friction between the brake pad and the brake hub to complete, when the motor vehicle is in the normal operation process, it is necessary to reduce the speed or stop the vehicle by the motor vehicle driver stepping on the brake pedal, and the brake of the motor vehicle is very soft, the brake system needs to be detected as a whole, find the cause of the failure, and then go to the symptomatic maintenance.

1. Brake oil pipe intake: brake oil is the medium transmitted by the braking system, if the oil pipe enters the air, the brake oil 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 method of judging whether the brake oil pipe is intake is to press the brake pedal a few more times in the flame-off state until the brake becomes hard, and then press the brake pedal and do not let go.

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 many 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 brake material is too soft: Under normal circumstances, the brake master cylinder or brake oil pipe leakage will cause the vehicle's brakes to become soft, and if the brake material is too soft, the high temperature stability will become poor, which will also cause the vehicle's brakes to become soft.

4. The use of brakes is clearly buried: According to statistics, there are many drivers who like to lightly step on the brakes with their toes, but in an emergency, they often can't brake the car. This is because pressing the brake with your toes will not push the brake pedal all the way in an instant, and the most correct way to apply the brake pedal should be with the force from your toes to the soles of your feet.

In addition, you should also pay attention to the heel of the right foot must not leave the ground, take the heel of the right foot as the axis, step on the accelerator to the right, and immediately press the brake on the left foot. In addition, it is important to drive predictively and slow down early when you perceive danger.

5. The new brake pads are not running-in: the new brake pads are still in the running-in, and it will be good after the run-in for a while.
