The function of the hand brake is to stabilize the vehicle after the vehicle stops and avoid the accident caused by the vehicle slipping on some roads. Many friends think that pulling the hand brake to the tightest point is OK. But in fact, pulling the hand brake at 100% force for a long time will shorten the life of the hand brake pull line, because excessive stretching of metal or prolonged stretching will accelerate the deformation, resulting in accelerating the hand brake pull line. Brake recession. In addition, the hand brake has its own independent brake mechanism. When the hand brake is not used, the brake shoe will automatically return through the return spring. If the hand brake is often used with 100% force, the return spring will be in a high tension effect, and over time, the return spring will lose its return function.
Long time parking on ramp with hand brake
Now parking space is scarce, many parking spaces are planned to the slope, the owner will directly use the hand brake to fix the brake after parking, because this will make the hand brake bear too much braking power, so that the brake wear faster, you can use a more practical method: bricks or other objects pad under the tire, and then pull up the hand brake so that the wheel and hand brake work together. If you are not confident, you can put the transmission rod into gear 1 or reverse, so as to achieve multiple insurance, and the automatic gear model must first hold the brake by hand, then put the gearbox into gear P, reduce the load of the gearbox, prevent the lock of the P-block trivial latch from being blocked so that it can not be unlocked normally.
However, we recommend that all car owners try not to park on the ramp, which injures themselves.
3. Handbrakes are strictly prohibited in high speed driving.
When driving at high speed, pulling the hand brake makes it easy to lock the rear wheel of one side and slip sideways. The correct way is to slow down by reducing gear. When the speed is very low, pulling the hand brake to stop the brake.
How to Maintain Handbrake
As a mechanical thing, besides good use habits, regular maintenance is also very important. Here we introduce the maintenance precautions of hand brake.
(1) Check the effectiveness of hand brake mechanism
Like the pedal of the foot brake, the handle of the hand brake has a pull stroke. Usually, when the handle is lifted to 70% of the whole journey, the brake system should be in the normal braking position, so before checking the braking power of the brake, we should first find out the 70% working point, which can be determined by counting the ratchets. You can park your car in a quiet place, slowly pull up the brake and count the ratchet clicks as you pull them up until the handle reaches the end. Then the 70% position of the total sound is calculated, which is the effective working point of the handbrake handle.
(2) Testing the sensitivity of hand brakes
In addition to braking efficiency, hand brake sensitivity should also be checked, which is particularly important for slope start. Drive slowly on the road without gradient. Slowly pull the handbrake handle to feel its sensitivity and joint point. This inspection method will wear the brake mechanism, so the number of inspections should not be too many. In the inspection process, if the braking efficiency or sensitivity of the hand brake is found to be unsatisfactory, it can usually be solved by adjusting the operating cables of the hand brake. There is an adjustable compensating mechanism at the bottom of the handbrake handle and the connection of the cable (usually covered by the inner trim). The length of the brake cable can be stretched by loosening the locking nut with a wrench. However, some automotive regulators are located at the bottom of the car. If you are not familiar with them, you should ask professional maintenance personnel to deal with them.
Summary: Handbrake seems simple, but it is the "system" that we often use in our daily driving life. Only by using and understanding the handbrake properly and correctly can we make the future use more smoothly. It is very important for safety. In addition, it can also prolong its adjustment cycle and reduce the cost of maintenance and replacement.
