How frequently do you use the car brake?
  • Automotive

First, determine the working position of the handle of the hand brake. Like the foot brake pedal, the handbrake handle also has a pull stroke. It is usually stipulated that when the handle is pulled to 3/4 of the whole stroke, the handbrake system should be in the normal position of the brake, so the working point should be found before checking the braking force of the handbrake, which can be determined by the sound of a number ratchet. Park the car in a quiet place, slowly pull up the handbrake, and pull the ratchet wheel ratcheting until the handle reaches the end. Then calculate the position of 3/4 of the total number of the sound, which is the effective working point of the handle of the hand brake, and can be marked with chalk on the slide rails of the handle. Next, it is to check the effectiveness of the hand brake mechanism. 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. Because of the brake memory in the gap, sometimes after the pedal is loosened, the car will slide slightly, and then stop, as long as the sliding distance is very small, the efficiency of the hand brake is also normal. The uphill and downhill should be done once. What needs to be reminded is that the car should be prepared for sliding when checking, so pay attention to the surrounding environment. 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. However, this kind of examination will cause the hand brake mechanism to wear out, so the number of checks should not be too much. In the above inspections, 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 copper cable (generally covered by the interior ornament). The length of the brake copper 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.
