Generally, the automobile brake pedal operation is divided into: slowly braking (being the foresight braking), emergency braking, Associated brake and intermittent braking.Generally speaking, slowly when braking and emergency braking at wheel lockup with before stopping, all pedal of clutch to be stepped on earth, in order to driving engine do not stopped working and be conducive to the speed of a motor vehicle of remapping:
1. slowly braking.Depress pedal of clutch, simultaneously close the throttle is pushed into the bottom gear position with shifter bar, lifts pedal of clutch immediately, and right crus of diaphragm is placed on rapidly on the brake pedal, the speed of a motor vehicle and point station distance as required, and the brake pedal that presses down with the foot down gradually is until parking.
2. emergency braking.Emergency braking during emergency braking is divided into again during low speed driving and the emergency braking when running at high speed.In emergency braking during low speed driving: both hands are held steering handwheel, depress pedal of clutch fast, almost depress brake pedal simultaneously, take a foot-operated dead method, and car is stopped rapidly.Emergency braking when running at high speed: because of speed of a motor vehicle height, inertia is big, poor stability, in order to increase the stability of brake efficiency and raising automobile, should depress brake pedal earlier during operation, before wheel lockup. depress pedal of clutch again, pin down the speed of a motor vehicle to utilize the driving engine slow speed of revolution.Behind the wheel lockup, front-wheel steering is get out of hand, and vehicle body easily breaks away.The main points that emergency braking needs to be grasped are: turn to get out of hand because of after seized, can the inertia of automobile advances to when very near apart from obstacle in when braking, can see the car that stop according to the speed of a motor vehicle, and vehicle is stopped, and then need detour when stopping incessantly.Answer the loosen the brake pedal when detouring, make steering handwheel play control action, depress brake pedal behind the cut-through thing again.Motor Vehicles in Emergency Brake Application easily produces sideslip, answers the settle brake pedal with the levelling vehicle body during sideslip.
3. Associated brake.Shifter bar is close the throttle in retaining, utilizes engine speed to lead resistance and reduces the speed of a motor vehicle, depresses brake pedal simultaneously and makes wheel braking, and this leading by driving engine hindered and method that car side brake is braked to slow down is called Associated brake.Associated brake uses morely normally travelling when need slowing down, the emphasis that should grasp is: during speed of a motor vehicle minimum standard, should in time change to a low gear, otherwise will accelerate to damage driving system in the speed of a motor vehicle is lower than this gear.
4. ask the braking of having a rest property.Ask that the braking of having a rest property is a kind of braking method that intermittently depresses with the loosen the brake pedal.Owing to long-term descending, brake system easily produces high temperature when mountain driving, causes deceleration and stopping performance to reduce, and too high for preventing the brake system temperature, chaufeur often uses intermittent braking method.In addition, Pneumatic braking device also can use quick intermittent braking because suction quantity is difficult for grasp.
