Avoid emergency braking Will you use the brakes correctly?
There are generally no two independent braking mechanisms for foot brakes and hand brakes on automobiles. The purpose of braking is to force a car to slow down quickly until it stops, or to maintain a certain speed when going downhill, and it can also be used to reliably keep a stopped car in place without slipping. In driving, the correct use of braking is not only conducive to ensuring driving safety, but also conducive to saving fuel, reducing tire wear and preventing damage to parts. How should the brakes be used correctly? Will you use the brakes? 1. Predictive braking The driver takes early deceleration braking measures for parking according to his own purpose or for the situation that has been discovered, which is called predictive braking. The method is to quickly lift the accelerator pedal to take full advantage of the engine's pull-in effect, while gently pressing the brake pedal to slow the car down. When the car is close to stopping, step on the clutch pedal and put the transmission in neutral to stop the car smoothly in the predetermined position. 2. Emergency braking In the case of sudden dangerous situations, the braking measures that have to be taken to make the car stop quickly are called emergency braking. The method is to quickly lift the accelerator pedal and immediately press the brake pedal hard, and at the same time pull the hand brake sharply, so that the car can stop quickly, this method not only makes the tires and chassis parts seriously damaged, but also easy to produce tail flicking, which is not conducive to driving safety, therefore, it cannot be used as a last resort. 3. Downhill braking No one will deny that downhill without braking is not good, but downhill cannot be completely braked. When going downhill, slow down and put up gears that match the speed of the vehicle, and only apply braking when the engine sound is unpleasant and the gear cannot control the speed. The method is that for air brake, the pedal should not be stepped on and released too much to avoid reducing the air pressure too quickly. The next stroke should be continued according to the required braking intensity; When you need to reduce the braking intensity, relax the pedal a little. On long slopes, as long as the air pressure is sufficient, appropriate intermittent braking can be used. In this way, it is conducive to the cooling of the brake hub and brake shoes. If you are driving a car that has exhaust brakes, you should use them as often as possible. For hydraulic braking, the brake pedal should be pressed twice, and then the pedal should be pressed with your foot so that the pedal is in a high proximity braking state. When you need to increase the braking force, step down a little more, and reduce the braking force and lift it a little. When the brake pedal height is gradually reduced, you can press it twice more to make the pedal height rise again.
