Friends who have a car family often encounter some unexpected situations in the process of driving. How should we deal with them? How to repair it? Make a few tricks for you. Emergency 1: the tire burst. If the rear tire burst, the rear part of the car will swing. The driver should hold the steering wheel with both hands to keep the car running in a straight line. At this point, the most important thing is not to step on the brakes, but to trample the brake pedal repeatedly and intermittently. If the blowout is the front tire, the driver must hold the steering wheel hard to keep the vehicle straight, do not let the vehicle left and right, and step down the brake pedal so as not to bear too much pressure in the front part of the car, which leads to the tyre disengagement. Emergency two: brake failure. First of all, control the direction of the driving, while ruthlessly stepping on the brake, if still can not slow down, should be quickly changed into the low gear, using the engine braking deceleration, while tightening the hand brake. If the car is still ineffective and the car may face the danger of collision or decline, it can also use the natural environment or facilities roadside, such as the roadside mound, bushes, haystack, etc., to help the car to slow down until it stops. Emergency three: front windshield glass broken. If the front windshield is broken by the flying stone raised by the rear wheel of the front vehicle, it is necessary to reduce the speed and leave the driveway as soon as possible; at the same time, keep calm, not to turn the steering wheel suddenly, or to brake excessively. It is suggested that the driver decelerate the road surface and traffic condition before the break of the windshield, then break the broken glass with hard objects and then brake. To completely knock down the broken front windshield, continue driving, and keep all windows closed when driving without front windshield. Emergency four: Car skidding. Small side adhesion, muddy road surface, sudden acceleration, uneven brake on front and rear wheels, irregular tire pressure and so on will cause sideslip. If it is the sideslip caused by the brake, the brake should be stopped immediately, the throttle is reduced and the steering wheel is turned to the side of the sideslip, and the steering wheel should not be too urgent or too long for the steering wheel, otherwise the vehicle may slide in the opposite direction. If it is caused by other reasons, try not to use the brake while siding, and keep the clutch in a state of engagement.
