Why do the brakes need to work twice in a row
Brake plays an important role in the car, through the way of braking can slow down and stop driving, play a good braking role. Why do you need to step on the brake twice in a row to use it?
Usually, the brake can be used normally only after two consecutive steps, mainly because when braking, the first foot on the brake only compresses the brake air. The second step on the brake can play the role of the brake, then you can play the braking effect by stepping on two times. When you need to step on the brake, you can step on half a foot first, lift it up and then step down, so you can get a higher brake pressure.
In addition, part of the reason is to prevent the owner from using the accelerator as the brake. Usually when the first foot on the brake can be directly found whether there is a wrong accelerator, no problem can be stepped on the second time to brake. Mainly through the friction generated between the tire and the body to reduce the speed, by lightly stepping on the brake to slow down, and heavy braking can be emergency stop.
