What causes brake pads to become soft?

Some drivers may feel in the driving process, sometimes the vehicle's brakes suddenly become very soft, step on the brake pedal after a period of time before the feedback of braking force, which may be in an emergency situation will cause traffic accidents.

So, what exactly is the cause of the vehicle brakes soft?

Air in the brake fluid line

Brake fluid is the medium of transmission of the braking system, if the oil pipe into the air, high pressure under the brake fluid will appear to be insufficient power, although there is still braking power, but the maximum braking power significantly weakened, at this time, should be timely to the maintenance enterprise for the braking system exhaust treatment.

The method of determining whether the brake fluid pipe into the air is, in the state of the engine off a few more brake pedal to the brake hard, and then step on the brake pedal does not let go, if it has been kept in a hard state that is normal, if the pedal slowly sinking, indicating that the brake system has been into the air.

Brake fluid has not been replaced for a long time

If the brake fluid is not changed in time, it will contain too many impurities and water, which will affect the transmission of braking power. Therefore, brake fluid must be replaced regularly, and if possible, the moisture content of the brake fluid should be tested at the maintenance company.

Leakage or brake material is too soft

In general, brake master cylinder or brake fluid pipe leakage will cause the vehicle's brakes to become soft; and if the brake material is too soft, the high temperature stability will become poor, which will also cause the vehicle's brakes to become soft.

According to statistics, a lot of drivers like to use their toes to lightly press the brake, but in an emergency, often will not be able to brake the car. This is because applying the brakes with the toes is not able to push the brake pedal to the bottom in an instant, and the most correct way to step on the brake pedal should be with a toe-to-toe force.

In addition, you should also pay attention to the right foot's heel must not leave the ground, to the right foot heel as the axis, to the right side of the foot to step on the gas pedal, to the left side of the foot immediately step on the brake. In addition, you should always drive predictably and slow down early when you perceive danger.

In fact, the frequency of using the brakes can show the level of the driver, a good driver should have foresight, which can effectively reduce the use of the brakes, thus reducing the frequency of replacement of the vehicle brake pads.
