I believe that friends who use cars often know that when a car stops in use, a handbrake will be used. If the driver leaves the vehicle, if there is no handbrake, then the vehicle may slip and may cause an accident. Sometimes, obviously, the brake has been pulled up, but the brake system failed, resulting in an accident. Therefore, the majority of riders should regularly maintain and check the car brake. The following Xiaobian gives you the attentions to check the normal maintenance of the handbrake. Like the foot brake pedal, the handbrake handle also has a pull stroke. Usually, when the handle is pulled to 70% of the whole stroke, the handbrake system should be in the normal position of the brake, so before checking the brake brake, the 70% work point should be found first. This work point can be determined by the sound of a number ratchet. You can park the car in a quiet place, slowly pull up the handbrake, and click the ratchet wheel to click until the handle reaches the end. Then calculate the 70% position of the total number of sound, which is the effective working point of the hand brake handle. Turn the car into a slope with a larger, better road condition (preferably the asphalt road), step on the brakes, and hang up the air (if it is automatic transmission on the N gear), and pull the handbrake handle to the position that you just decided. Then slowly release the brake pedal. If the car does not slip, it shows that the brake is good. The uphill and downhill should be done once. Many owners believe that when braking system fails, the brake can be pulled down to slow down. In fact, this practice is very dangerous. Because the hand brake mechanism is not precise, the distribution of brake force on both sides is uneven. It is easy to pull the hand brake on the side of the hand brake when driving at high speed. The right thing to do is to slow down by lowering gear, and then pull the brake when the speed is very low. In addition to braking efficiency, the sensitivity of the hand brake should also be checked, which is especially important for the start of the slope. Drive slowly on the road without slope, gently pull the hand brake handle, and feel the sensitivity and engagement point of the handle. This kind of examination method will cause the hand brake mechanism to wear out, so the number of checks should not be too much. During the inspection process, if the brake efficiency or sensitivity of the handbrake is found to be unsatisfactory, it is usually possible to solve the problem by adjusting the operation of the brake. There is an adjustable compensatory mechanism at the bottom of the handle of the hand brake and the connection of the cable (generally covered by the interior ornament). The length of the brake cable can be stretched by the wrench loosening the locking nut. However, some automobile regulators are located at the bottom of the car. If they are not adjusted, they should be handled by professional maintenance personnel.
