How to determine if the brake cylinder is broken, and what is the impact of the brake cylinder being

How to determine that the brake cylinder is broken is as follows:1. Soft brake: When the brake is pressed, if the texture of the brake is obviously soft, and the stability of the continuous brake is reduced, it may be that the piston seal of the master cylinder and sub-cylinder is poor, or the brake pipeline is ruptured somewhere, resulting in oil leakage.

2. Sudden brake failure: When the car is braking, if it feels that there is a sudden failure for a moment, it is necessary to observe whether the brake fluid is lost, and then check whether the master cylinder, sub-cylinder and oil pipe have any traces of brakes. Q3: Brake deviation:

If you feel that the brake direction is misaligned, it is likely to be caused by the expansion of one piston of the master cylinder, and of course, it may also be caused by uneven brake wear.

4. The brake pedal does not return or returns slowly: If the brake pedal is neither raised nor resisted after the brake pedal is pressed, it is the so-called brake non-return phenomenon. At this time, it is necessary to check whether the parts of the main pump and sub-pump are damaged.

The performance of the broken brake cylinder of the car is that there is oil leakage at the connection between the cylinder and the oil pipeAfter pressing the brake pedal, the steering wheel is obviously deviated to one side, which is likely to be caused by uneven wear of the brake pads or the failure of the cylinder, and the pedal does not rise after pressing the brake pedal.

The brakes will fail if the following parts are broken:

The brake pads are faulty. The brake pads are gone, or the brake pads are overheated and the coefficient of friction is reduced. Because the brake pad is the terminal actuator of the brake, it will naturally fail to brake without it, and the brake will fail.

If you step on the brakes for a long time on a long downhill section, the friction coefficient will be greatly reduced due to the overheating of the surface, and you will not be able to brake because of the large friction force.

Impact: 1. Abnormal noise during braking.

When the brake is stepped on while the vehicle is moving, the brake system will emit a sharp and piercing metal friction sound, which may be caused by the thinning of the brake pads, the quality of the brake pads, foreign objects in the brake pads or rusty brake discs.

2. The brakes are soft.

When braking in the car while driving, the braking deceleration is small, the braking distance is long, and the reasons for the poor braking efficiency of the hydraulic braking system can generally be judged according to the brake pedal stroke, the soft and hard feeling when the brake pedal is pressed, and the stability after stepping the brake pedal.

If the height of the pedal decreases slowly while braking is maintained, it indicates a rupture in the brake line, poor sealing of the joint, poor piston sealing of the master cylinder or sub-cylinder, and poor return valve and outlet valve. You can first step on the brake pedal to observe whether there is any brake fluid leakage.

3. Brake deviation.

Brake deviation is also brake deviation, brake deviation phenomenon is the owner when the brake steering wheel has obvious deviation to one side, that is to say, the braking force is large, and the braking force is small. The main reason for this situation is that the brake pads are worn or there is a problem with the brake cylinder, so once this situation occurs, you need to go to the repair shop for inspection.

The brake cylinder is the brake caliper in the hub.

There are only two cases when the sub-cylinder is damaged, it cannot be braked, or it cannot be quickly separated after braking.

The direct impact is that either there is no brake, or the brake is all the time, and the car can't run.

Hello! Oil leakage leads to poor braking effect, and rusting of brake cylinders leads to high fuel consumption and slow car speed. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, the damage to the brake cylinder is manifested in the decline of braking performance, or the brakes are locked, and the car cannot move. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

The performance of the broken car brake cylinder is that there is oil leakage at the connection between the cylinder and the oil pipe, the brake pedal will feel soft, and the steering wheel is obviously deviated to one side after stepping on the brake pedal, which is likely to be caused by uneven wear of the brake pad or the failure of the cylinder, after stepping on the brake pedal, the pedal is not raised, there is no resistance, that is, the brake does not return.

If the main pump is broken, the pressure will be relieved, which will cause the brake to be unstoppable, and the vacuum pump will be broken, and the brake will be very hard and cannot be stepped on.

The brake master cylinder, also known as the "brake master cylinder" and "brake master cylinder", is the main part of the vehicle braking system. According to different vehicles, it is also divided into two kinds of air brake master cylinder and oil brake master cylinder, under normal circumstances, most of the brake master cylinders of passenger cars (such as cars, micro-buses, etc.) use oil brake master cylinders, and the brake master cylinders of commercial vehicles (such as trucks, tractors, etc.) generally use air brake master cylinders.

If the sub-pump is rusty, the wheels are not flexible. If the wheels are hot when running and the sub-cylinder leaks, the brake pedal will be too low, the brake will be soft, and the braking performance will not be good.

The sub-pump is rusty, and it also causes the wheel to burst to death in advance, and it is easy to deviate when stepping on the brakes. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

1. The braking performance deteriorates, and the braking distance becomes significantly longer.

2. Failure to return in time leads to continuous friction of brake pads, and thermal attenuation due to temperature increase.

3. Brake deviation, after stepping on the brake, the vehicle has an obvious offset trajectory, which may be caused by the failure of the brake cylinder.

4. Violent abnormal noise when braking.

The broken wheel didn't brake.

Many drivers of long-distance transportation, before driving on the road, will check the performance of the vehicle, especially check whether the vehicle's braking system is intact, so that after a detailed inspection, to ensure the safety of the vehicle will be on the road, and for some inexperienced drivers, when the vehicle braking system is abnormal, it will be more panicked, do not know how to determine the quality of the brake cylinder.

1. The owner can judge by stepping on the brakes, when stepping on the brakes, if it is obvious that the brakes are hard, and the stability of the brakes has also decreased, then it is necessary to consider the abnormality of the master cylinder or sub-cylinder.

2. Usually in the process of driving, when stepping on the brakes, if you feel that the brakes suddenly fail, then pay attention to check the situation of the sub-cylinder.

3. If the vehicle is found to be prone to deviation during the braking process, it may also be caused by damage to the sub-cylinder.

4. When the driver steps on the brake, if he finds that the brake pedal is slow to return, or even does not return, it should also be considered that the parts of the master cylinder or sub-cylinder are damaged.

Hello, judge the reputation of a car's brake pounds. Oil leakage, lock-up. First of all, you take a look at the tire to see if it is leaking, oil leakage, this method needs to be replaced, if the tire can't turn, and you can't pry it with a screwdriver, then the wind pump is dead and closed, and it also needs to be replaced.

Vertical scrambling. Brakes are soft. How to determine that the brake cylinder is broken.

If the brakes are weak, first of all, you exhaust the air, is there moisture in the brake fluid? There is also a possibility that the master pump is not internally relieved

If the pump is divided, the oil leakage dies violently, and other soft master cylinder problems generally do not occur.
