What are the symptoms of a faulty brake cylinder?

The working environment of the brake cylinder is very harsh, in addition to the metal powder contamination caused by the wear of the brake pads, it also has to experience high temperature and rain. Moreover, the brake cylinder is connected to the brake pads, and the fault is mainly manifested in the abnormal brake noise and return, and some brake cylinders are also connected to the brake oil pipe, so there will be oil leakage. The main symptoms are as follows:

1. At low speed, the metal friction sound in the car is the same as the rotation frequency of the wheels, which is especially serious when the traffic jam slows down.

2. The brake does not return. Press the brake pedal, the pedal is not raised, and there is no resistance.

3. The brakes become softer. When braking while the car is driving, the braking deceleration is small, the braking distance is long, and the braking efficiency of the hydraulic braking system is poor.

The brake cylinder is an indispensable chassis brake part of the braking system, and its main role is to push the brake pads, and the brake pads rub against the brake drum to reduce the speed and stationary. After the brake is pressed, the master cylinder generates a thrust to press the hydraulic oil to the cylinder, and the piston inside the cylinder begins to move under hydraulic pressure to push the brake pads.

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.

Hello, check the oil return of the brake master cylinder and ABS pump, and finally check whether the brake cylinder does not return.

What happens if the brake cylinder is broken:

1. Abnormal noise when braking: when the vehicle is driving, the brake system will emit a sharp and harsh metal friction sound, which may be caused by the thinning of the brake pads, the quality of the brake pads, the foreign objects in the brake pads or the rust of the brake discs.

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 brake master cylinder, sub-cylinder and oil pipe have any traces of brakes. If there is, it means that the brake cylinder or master cylinder has a serious oil leakage, and it must be repaired in time, knowing that the consequences of brake failure are very dangerous.

3. Soft brakes: When we step on the brakes, if we feel that the texture of the brakes is obviously soft, and the stability of the brakes is reduced continuously, it may be that the brake master cylinder and the piston of the sub-cylinder are poorly sealed, or the brake pipeline is ruptured somewhere, resulting in oil leakage. At this time, we need to observe whether there are traces of brake fluid.

4. Brake deviation: Brake deviation is also brake deviation, and the phenomenon of brake deviation is that the steering wheel has obvious deviation to one side when the owner steps on the brake, that is to say, the braking force is large on one side, and the braking force is small on the other. This kind of failure is not very common, and once it occurs, it can cause a huge accident.

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. Check and correct the amount of deflection of the front brake disc.

5. When stepping on the brakes: Many car owners have encountered such a situation, when stepping on the brakes, the brake pedal has the phenomenon of top feet, and this phenomenon is mostly caused by the uneven surface of the brake disc and brake pads, and the deformation of the steel rim.

Kiss! Hello, the brake cylinder is not a wearing part, and most of the damage to the cylinder is due to quality problems; The oil quality is too dirty, resulting in the blockage of the brake oil pipe and the excessive pressure of the master cylinder, which is ineffective and the oil pump is easy to damage after a long time.

2. Secondly, the damage of the sub-cylinder will also have a certain relationship with the failure to replace the brake disc in time, and when the brake disc and brake pad are worn to the limit, it may cause damage to the sub-cylinder if they are continued to be used;

3. The oil quality is too low or the time is too long to deteriorate, resulting in easy corrosion of the sealing bowl in the master cylinder, which will cause poor sealing after a long time, and the oil cannot be sealed without oil pressure, which will lead to damage to the oil pump.

What is the cause of the constant damage to the brake cylinder.

The sub-pump has been replaced twice, but it is broken again, the first foot does not brake when the brake is pressed, and the third and fourth feet are there, what is the specific situation.

Pro: After replacing the brake cylinder, because there is air mixed in the pipeline, there is no brake, that is, you can step on the bottom with one foot, and there is no resistance. Multiple vents are required before they can be brought back into service.

But it didn't take a few days for the oil to leak.

The symptoms of automobile brake cylinder failure are as follows:

1. If the brake cylinder has an abnormal sound, it means that the brake cylinder is faulty. Check the brake cylinder: if the piston ring of the brake cylinder is stuck, then the brake cylinder needs to be replaced; If the iron plate of the fixed brake pad of the brake cylinder is deformed, then the iron plate needs to be replaced;

2. The brake cylinder is an indispensable chassis brake part of the braking system, and its main function is to push the brake pads, and the brake pads rub against the brake drum. Reduces the speed of the vehicle and makes it stationary. After the brake is pressed, the master cylinder generates a thrust to press the hydraulic oil to the cylinder, and the piston inside the cylinder begins to move under hydraulic pressure to push the brake pads.

3. Heavy trucks use gas brakes, and general cars are oil brakes, so the main brake cylinder and brake sub-cylinder of the car are hydraulic brake pumps. The brake cylinder (hydraulic brake cylinder) is an indispensable part of the braking system, when you press the brake plate during braking, the brake master cylinder will send the brake oil to the brake cylinder through the pipeline. The brake cylinder has a connecting rod that controls the brake shoe or brake pad.

When braking, the brake fluid in the brake oil pipe pushes the connecting rod on the brake cylinder, so that the brake shoe tightens the flange on the wheel to stop the wheel. The technical leasing technique of the brake cylinder of the car is very demanding, because it directly affects people's lives.

Millions of car purchase subsidies.

There are brake master cylinders and brake sub-cylinders in the braking system. In simple terms, the master cylinder is where the brake fluid is stored, and it has an oil outlet and an oil inlet. When we press the brake pedal, the oil in the brake master cylinder flows through the line to the brake cylinder.

When the driven cylinder is pressurized, it will push the brake pads to make the brake pads rub against the brake drum, so as to achieve the purpose of braking. The brake cylinder does not return. To put it simply, even if you don't press the brake pedal, you can still clearly feel the drag of the car.

In severe cases, it will make abnormal noises and even lock the wheels. If you do not change the brake fluid for a long time, resulting in corrosion inside the brake cylinder, you can repair it with sandpaper sanding and buttering; If the sub pump itself fails, it is likely to be replaced. The symptoms of car brake cylinder failure are as follows:

1。The noise of the brake cylinder indicates that the brake cylinder is faulty. Check the lower brake cylinder:

If the piston rings of the brake cylinder are jammed, the cylinder needs to be replaced. If the iron plate of the brake cylinder fixing the brake pads is deformed, then this iron plate should be replaced. 2.

The brake cylinder is an indispensable chassis brake component in the braking system. Its main function is to push the brake pads, which rub against the brake drum. Slow down and stop.

After the brake is pressed, the main cylinder causes thrust to push the hydraulic pressure to the sub-cylinder, and the piston inside the sub-cylinder starts to move under the action of the hydraulic pressure to push the brake pads; 3.Heavy trucks use air brakes, and most cars basically use oil brakes. Of course, the main cylinder and the sub-cylinder of the automobile brake are basically hydraulic brake cylinders.

Brake cylinders (hydraulic brake cylinders) are an indispensable part of the braking system. When you press the brake pad during braking, the brake master cylinder delivers the brake fluid through the lines to the individual brake cylinders. The brake cylinder has a connecting rod to adjust the brake shoe or brake block.

When braking, the brake oil in the brake oil pipe pushes the connecting rod on the brake cylinder, causing the brake shoe to tighten the flange on the wheel and stop the wheel. The technical requirements of the brake cylinder of automobiles are very demanding, as it affects people's lives at the same time.
