What is the reason for the soft brakes of the car?How long does it take to recover after changing the brake fluid?

Under normal circumstances, the brake becomes softerBrake FluidThe quality, work performance, and whether the brake fluid replacement operation is standardized are closely related. There are many reasons for the softening, which are more complicated. It is necessary to find the specific cause of the brake softening and solve the related faults before recovery. Therefore, if the brakes become soft after replacing the brake fluid, the brakes will not recover on their own, and you should go to the maintenance organization for repairs in time.

What are the reasons for the softening of car brakes?

1. Air entered when the brake fluid was replaced. Brake fluid is the medium through which the brakes transmit braking force. If air enters the brake hose, the brake fluid will not have enough strength under high pressure, and the brake will become soft.

2. The brake oil has not been replaced for a long time. If the brake fluid is used for a long time, the moisture and impurities inside will continue to increase, which will affect the normal transmission of braking force. Therefore, the brake fluid should be replaced regularly to solve the problem of soft brakes.

3. The brake fluid is leaking. Brake fluid is the main medium for transmitting braking force. If there is an oil leak, the effect of transmitting braking force is not good, and the brakes will become soft. You can go to a 4s shop or a regular repair shop for maintenance.

Attachment: Method of exhausting air from brake hose

First of all, this method requires the cooperation of two people. One person is responsible for stepping on the brake several times, while the other person loosens the bleed screw of the brake cylinder at this time. If there is air in the brake hose, some brake fluid and air will be sprayed out. Repeat the operation several times. When no air is sprayed out again, it means that the air has been drained.
