What should I do if the brake becomes soft after changing the brake pads

The brake system is a very important part of the car, and it is the guarantee of travel safety. The brake system consists of brake pads, brake discs andBrake FluidComposition, the car is in use. Brakes are often used, and the brake pads will inevitably wear out and need to be replaced in time. However, if the brake pads are replaced, there will be new problems, that is, the brakes become soft after the brake pads are replaced. What should I do?

Reasons and solutions for soft brakes

1,Leaking or intake of brake hose

If the performance of the brake fluid is not good, the friction between the brake pads and the brake disc will be insufficient, and the driving time will be long, and the brake fluid pipe may be aging and damaged.,The brake fluid will leak or the air will enter the oil circuit, and there will be an air barrier between the brake pads and the brake disc, which will cause the brake to become soft. At this time, the oil pipe needs to be replaced to remove the air.

2,Brake oil has not been replaced for a long time

If the brake fluid is not replaced in time, there will be too much hybrid and moisture inside, which will affect the transmission of braking force. Therefore, the brake fluid must be replaced regularly. If possible, go to a professional repair shop to check the moisture content of the brake fluid, and replace it if necessary.

3.The new brake pads are not running in

The surface of the newly-changed brake pad is relatively flat, and the contact surface with the brake disc is small, and the braking force will be relatively low, which will cause the brake to fail. The replacement of new brake pads requires a run-in period, generally about 200 kilometers. Only after the run-in period can the best braking effect be achieved.
