Correct brake air exhaust method and ingenious brake air exhaust method

Judge whether there is air entering the brake pipeline

When the brake pedal is pressed for the first time, the soft cotton is unable to press it continuously for several times, and the brake pedal rises step by step. If it does not move and feels elastic after rising, it indicates that there is air in the brake system, which is prone to air resistance, so it is necessary to empty the air in the brake system.

Correct brake air exhaust method

1. Remove the vent dust cover on the slave cylinder, prepare a transparent rubber hose, connect the vent valve and the plastic container at the same time;
2. One person depresses the brake pedal several times in the vehicle, and then forcibly depresses the brake pedal to a standstill. The other person looses the bleeder screw on the wheel cylinder outside the vehicle. At this time, the air will be discharged together with the oil;
3. Repeat the above operations until there are no bubbles in the discharged oil, then fill up the brake fluid and tighten the bleeder nozzle.

matters needing attention:

1. The exhaust wheel sequence is generally right rear wheel - left rear wheel - right front wheel - left front wheel.
2. The discharged brake fluid cannot continue to be used because it may be in long-term contact with air and absorb moisture, which may affect the braking efficiency.

How to self check and maintain the car brake system

The car must not only run, but also brake. Then it becomes particularly important to check the brakes in the process of daily use.
In daily life, you can use a simple method to judge whether the brake works normally. When stepping on the brake again, the car body shakes forward, which is normal. ABS starts. However, if it shakes left and right, or deviates during emergency braking, there is likely to be a problem with the braking system. It is best to check it immediately

.
When the car is on, the brake is assisted, but when the car is on, the brake is particularly hard, or if the brake is pressed down and does not rebound, there is a very likely problem with the brake oil. In addition, if the foot feel of the brake is obviously softer than before, and the braking effect is discounted, it is likely that the brake master cylinder has entered gas.

Open the engine compartment cover to see whether the brake oil is enough or too little. If the brake oil is insufficient after adding the brake oil, it is likely that there is oil leakage in the brake system. This situation is somewhat dangerous. It is necessary to check where the oil is leaking in time.
There is an alarm pad on the brake skin. When the brake pad has been worn to the limit, the alarm pad will rub with the brake disc and make a very harsh sound. At this time, the brake pad has reached the limit state and must be checked and replaced immediately. In addition, you can simply check whether the brake pad needs to be replaced by visual inspection of the rim. Generally, when the brake pad is only about 5mm left, you need to check frequently and prepare for replacement. If only 2mm is left, it is the limit. It's best to replace it immediately.

The brake disc should be replaced in time if the wear on both sides is 3-4mm. The brake disc can be used for more than 100000 km. There is slight rust on the brake disc. Don't worry. Generally, the rust is produced by small metal dust rubbed down.
