Brake fluid. At present, the observation window is basically made of resin, which is a relatively brittle material. If only the observation window is broken, there is no other problem with the upper pump, and the observation window can be changed separately, which can save dozens of dollars for changing the pump.

By the way, there is also an oil seal under the viewing window.

It is to prevent oil leakage, and if it is broken, remember to replace it in time.

**Search for "upper pump oil mirror" and "brake pump oil mirror" can be found, only a few dollars.

If it is a brake oil pot, it must be replaced with a new one, safety first.

In the past, the oil leakage was solved by removing the engine and changing the oil seal, but now with the development of science and technology, the oil leakage problem can also be solved by not dismantling and repairing.

More than 90% of the oil leakage problems are due to the alternating change of cold and warm temperature of the rubber seal for a long time, resulting in the loss of a large number of plasticizers and softeners in the sealing ring, and the problem of corrosion, aging and hardening.

1. The oil quality is too dirty, which leads to the blockage of the brake oil pipe and causes the pressure of the master cylinder to be too large, and after a long time, the brake is ineffective and the oil pump is easily damaged.

2. The oil quality is too low or the time is too long, which leads to the corrosion of the sealing bowl in the master cylinder, which will cause poor sealing after a long time, and cannot seal the oil without oil pressure.

3. Frequent lack of oil or dry grinding will cause wear and tear of leather bowls.

4. Frequent use of brakes will also be unfavorable to brakes.

Brake master cylinder oil leakage is due to damage to the sealing ring, which cannot be sealed effectively, and the pressure during braking is very high, and leakage occurs.

The reasons for the oil leakage of the brake cylinder are as follows:

1. The brake oil pipe is ruptured (leaking in the link from the brake pump to the pipeline), the brake oil pipe is connected to the brake pump and the top column of the brake pad, when the brake pedal is pressed, the brake oil will be transmitted to the piston of the caliper through the oil pipe, and the piston will push the brake pad to squeeze the brake disc, thus producing a braking effect. Then when the brake hose is broken, there will definitely be oil leakage;

2. The sealing rubber ring is damaged (leaking on the sealing rubber ring), the brake fluid is very corrosive, although the sealing rubber ring has the ability to resist, but in the long run, it will more or less age, and the natural sealing effect will also decline, resulting in oil leakage;

3. If the oil pipe screw is loose or damaged (leaking on the brake drain hole), the oil pipe screw is used to seal the brake oil in the oil pipe. If the tubing screws are damaged, oil leakage will naturally occur.

Solution to brake pump oil leakage:

1.Replace the brake pump oil line;

2.removal of impurities or replacement of seals;

3.Reinstall the brake pump screws.

If the brake cylinder leaks, not only will you feel that the level of the brake pedal is soft, but it may also suddenly fail the brake, which is harmful to safe driving. So, when you find an oil leak from your brake cylinder, be sure to deal with it properly.

Reasons for brake cylinder leakage of oil in Buyu:

1.The internal leather bowl of the sub-pump is cracked, resulting in oil leakage, but it is generally not easy to be serious;

2.There is a problem with the connection gap between the piston rod and the inner cavity of the driven cylinder (asymmetry, abnormal damage caused by foreign body sensation, etc.). ).Naturally, it may also be due to the aging of the sealing cup, resulting in oil leakage from the brake cylinder;

3.Quality problems with brake fluid (brake fluid) products. Some friends buy brake fluid in some small shops because of greed, and these devices usually do not have a quality assurance certificate. Secondly, it is harmful to choose a brake fluid grade and model that does not match the size.

As a general rule, if a brake cylinder leaks, a new brake cylinder must be removed and replaced immediately (repair and rent). Secondly, if the brake fluid used by yourself has product quality problems, it must be replaced completely.

For the removal and replacement of the front tire brake cylinder, you should try to go to the corresponding car 4S shop or car repair shop to solve. After all, it's a big project. If it is not used properly, it will not be ** when the time comes. Naturally, if you're particularly proficient, you can do it yourself.

Brake fluid is what we usually use when driving, in fact, it is very important for our driving, and it is related to brakes, so we should have an understanding of the use of brake fluid, but sometimes brake oil pump leakage will occur, so let's take a look at the specific performance of brake oil pump leakage.

1. Soft brakes may be oil leakage from the brake oil pump.

If the brake oil pump leaks, first of all, when the car is braking, the braking deceleration is small, the braking distance is long, and the reason 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 the brake pedal is pressed. When maintaining braking, if the pedal height drops slowly, it means that the brake line is broken somewhere, the joint is poorly sealed, the master cylinder or slave cylinder piston is poorly sealed, and the return and outlet valves are poor. First, press the brake pedal and observe if there is any brake fluid leakage.

If the appearance is normal, check for the fault of the sub cylinder or master cylinder. When you press the brake several times in a row, the height of the pedal belt plate increases slightly, and there is a spring**, indicating that air has infiltrated the brake line.

Second, the sudden failure of the brake may be the leakage of the brake oil pump.

When the car is moving, one or several feet brake continuously, the brakes are all pressed to the end, and the brakes suddenly fail. Cause: Serious oil leakage from the brake master cylinder or driven cylinder; The piston seals of the master or driven cylinders are damaged, or there is too much air in the brake oil circuit.

If this happens, the driver should brake quickly and continuously with both feet. If the brakes fail, stop and check immediately. First, observe whether there is any loss of brake fluid in the brake fluid box, and then observe whether there is brake fluid leakage in the master cylinder, slave cylinder and oil pipe.

Third, the brake will not be the brake oil pump leakage.

When you press the brake pedal, it feels high and stiff or there is no free stroke, and it is difficult or difficult to drive when you start the sail in a self-conscious position. Symptom: When the brake pedal is pressed, the pedal does not rise and there is no resistance.

It is necessary to determine whether the brake fluid is missing; whether there is oil leakage from brake cylinders, pipes and joints; Whether the parts of the master cylinder and slave cylinder are damaged.

As for the situation of the brake oil pump leakage, we can find that the brake oil pump leakage actually explains something. The details about the brake oil pump leakage have been introduced above, and we can find that the brake oil pump oil leakage shows some things, mainly the brakes. If something goes wrong, we should check it in time.
