The professional title of the hand brake is the auxiliary brake, which is different from the principle of the brake. It is used to connect the rear brake shoe with the steel wire, to brake the car. Long-term use of hand brake can cause plastic deformation of steel wire. Since this deformation is not recoverable, long-term use will reduce utility, and the trip of hand brake will increase.

The handbrake is also used in response to the spring. Pull the hand brake, the spring is elongated; Release the hand brake and the spring return to the original length. When the hand brake is used for a long time, the spring will also produce the corresponding deformation.

Do not forget the handbrake

If you forget to pull your hand on the brakes when you stop, you may not be too dangerous to walk on your foot. But if you run into a traffic jam in the middle of the slope, the owner forgets to pull the handbrake, which is very dangerous.

The owner's effort to use on the step on the gas and loose clutch, and ignored the foot brake, the vehicles will fall, behind plus other vehicles kept warning sound of the horn, make the owner feel more nervous, hurriedly lift the clutch, the car will be shut down, and then rapidly after the fall, so that the touch behind vehicles.

Emergency measures: encountered car was blocked in the banpo, of a phenomenon, the owner of the first thing to do is to calm, don't be panic, quickly on the foot brake, let the car to stop, and then gently shake handshandle brake, slowly release the foot brake. At this point, the foot is best not to leave the foot brake, determine the handbrake, and then loosen the feet.

The correct method: when driving on a daily basis, it is better to keep a certain distance with other cars, and immediately take a series of remedial measures such as stepping on the foot brake and holding the handbrake. Parking at the same time, for a long time, still have to be vigilant, be sure to remember the shake handshandle brake, such not only can let feet get rest for a period of time, also need not worry because the distractions and loosen the foot brake, resulting in the slide occur.

2 high speed driving, hand brake can not be replaced

Many owners think that, in the high speed or sharp curves, meet the crisis can be directly handle brake to slow down, in emergencies, hand can replace the foot brake, let the car stop immediately. In fact, it is wrong and dangerous.

The main function of hand brake is to control the speed of rear wheel. But in the fast moving, the braking force of the handbrake is very small. If the owner drives the hand brake at high speed, it will be easy to hold the rear wheel to the dead, pull the line to be pulled off, and then the vehicle will be skidded, or even overturned. And in turn or driving in the rain, snow and ice, also do not use hand brake sharply, or the ABS system will be failure, doesn't have any rear wheel speed signal, prone to running deviation and flings tail phenomenon.

Emergency measures: in high speed, emergency stop, and when the foot brake doesn't work and problems, the first thing to do is to loosen the throttle, by dropping gear deceleration, the smooth speed slightly, the speed is lowered obviously, then handle the brake will stop the car brake.

The correct approach: in general, in the high speed shall try to stop the vehicle, using a snub to the situation, had better not use in high speed handbrake to forcibly stop the vehicle, it can be very dangerous.

3 carry on brake running, brake loss big

The most immediate effect of driving with the hand brake is that the brake disc accelerates the wear and the brake pad is hard and the handbrake line is elongated. This can lead to a decline in braking performance, and sometimes the smell of the car is also coming from the car. In severe cases, there will be a smoking phenomenon. If you take a long time to drive on the brakes, it can also cause the brake pump to die, brake oil leakage, and the temperature of the brake fluid is too high, resulting in the complete loss of brake function.

Generally speaking, the faster the speed of the car, the greater the loss of the brake and the damage to the tire.

Emergency measures: if you meet with a hand brake on the driving, and there is a serious burnt smell and smoke, the car owner should immediately slow down, brake, and drop the handbrake. The car should be pulled over to the side of the road, and the car should be pulled down to see if there are any other abnormalities. Don't just put your hand on the brakes and keep going in the heat.

Correct approach: the correct driving habit, before to see if a handbrake have loosen when driving, but also pay more attention to the dashboard, relatively speaking, dashboard showed the most comprehensive information, observe the dashboard information, warning lights, can avoid to brake driving behavior.
