Hand brake professional title is auxiliary brake, and the principle of the brake is different, it is connected to the rear brake shoe wire to the car to brake. Long-term use of handbrake will make plastic deformation of steel wire, because this deformation is irreversible, so long-term use will reduce the effectiveness of handbrake travel will increase.

And the hand brake supporting the use of a return spring to pull the hand brake when the spring is stretched; hand brake release, the spring back to the original long-term use of handbrake, the spring will produce a corresponding deformation.

1 section of the traffic jam, remember to forget the hand brake

If you normally stop when you forget the handbrake, the vehicle appears after the slip, tighten the foot brake, may not be too dangerous. But if encountered in the Banpo traffic jams, car owners forget to pull the handbrake, it is very dangerous.

At this time the owner of the energy are used in the step on the throttle and loose clutch, while ignoring the foot brake, then the vehicle will decline, plus other vehicles behind the continuous horn warning sound, so that owners feel more nervous, hurriedly From the clutch, the car will turn off, and then quickly down, so that behind the vehicle encountered.

Emergency measures: all encountered in the car was blocked in the Banpo, after the phenomenon of slipped, the owner must first do is calm, do not panic, quickly slam the foot brake, let the car first stop, and then light hand brake , Slowly loose foot brake. At this point the foot is best not to leave the foot brake, to determine the hand brake after the prison, and then release the foot brake.

The correct way: in the daily driving, the best and other vehicles to maintain a certain distance, once the car after the slip, should immediately take a step on the brake, pull the handbrake and a series of remedial measures at the same time, long parking conditions, Be vigilant, be sure to remember the handbrake, so that not only can let the feet get a rest for a while, but also do not have to worry about because of distraction and release the foot brake, which led to the phenomenon of car slip.

2 high-speed driving, handbrake can not step on behalf of the brake

Many owners believe that in the high-speed driving or a sharp turn, the sudden crisis can be directly pull the brake to slow down, in an emergency moment, handbrake can replace the foot brake, so that the car immediately stop moving forward. In fact, this approach is wrong, and very dangerous.

The main role of handbrake is to control the speed of the rear wheels of the vehicle. But in the fast driving, the hand brake braking force is very small. If the owner in the high-speed driving handbrake, it will be easy to make the rear wheel lock, pull the cable was pulled off, will be when the vehicle will slip, and even roll and so on. At the same time in the sharp turn or rain, snow and ice in the road, do not quickly use the handbrake, otherwise the ABS system will be invalid, the rear wheel no speed signal, prone to deviation and flick.

Emergency measures: in the high-speed driving, to emergency stop, and the foot brake problems do not work, the first thing to do is to release the throttle, through the downshift to slow down, the speed was slightly stable, the speed dropped significantly, And then pull the hand brake will stop the car.

The correct way: Under normal circumstances, in high-speed driving should try to use the point brake to let the vehicle to stop, less than a last resort, it is best not to use high-speed brakes in the way to force the vehicle to stop, this will be very dangerous.

3 with a hand brake, brake loss

This will lead to decreased braking performance, and sometimes the owner smell the smell is also the resulting, in serious cases, there will be smoke the phenomenon of the rear. If you hold the hand brake for a long time, may also lead to brake cylinder killed, brake oil leakage, brake fluid temperature is too high, resulting in complete loss of braking function.

In general, with a hand brake, the faster the speed of the brake on the greater the loss, but also some damage to the tire.

Emergency measures: in the driving if you encounter with a hand brake, and the emergence of a serious fog and the rear smoke situation, the owner should immediately slow down, brake, put the hand brake at this time can not move forward, the car should be docked Roadside, to be cool down, carefully observe whether the other strange.
