First, the structure of the handbrake The current family car handbrake is on the rear wheel, mainly divided into drum brake and disc type (disc brake) two kinds.
1, Drum brake handbrake Many entry-level car brakes are used in front of the rear drum form, the hand brake is achieved through the rear drum brake. When pulling the handbrake, pull the brake shoe in the drum brake through the handbrake cable to achieve the brake parking.
2. The rear brake of the disc brake is the model of the disc brake. The hand brake directly controls the brake caliper to realize the brake parking.
3, disc drum brake This is a disc brake and drum brake combination of a braking method, disc brakes responsible for the daily brake, drum brake is responsible for parking.
4, with independent handbrake caliper Some super running using the brand's brake caliper, without handbrake function, so need a separate caliper to play the role of handbrake.
Second, the mechanical handbrake need to pay attention to the use of 1, can not pull too tight Mechanical hand brake in daily use remember not to pull too tight, because the metal cable over-extension or long-term extension will accelerate the deformation aging, resulting in hand brake change Loose or broken wire. The correct approach is to pull up the handbrake until the rear wheel is locked up and then lift up one or two grids to ensure that the car does not slip.
2. Don't park the ramp parking for a long time by a ramp, parking by hand brake will accelerate the abrasion of the handbrake cable. The correct approach is to park the vehicle with parking brake after parking, then place a brick on the front side of the wheel on the side of the slope, release the handbrake and let the force transfer to the wheel and then pull the handbrake.
3. Do not pull the handbrake after the ice and snow days and after the winter car wash. After the winter ice and snow roads are used, the handbrake may be frozen and frozen, causing the vehicle to be unable to travel. In addition, in the winter car wash, be careful not to pull the handbrake, you can use the gear or brick to replace the parking brake.
Third, the electronic handbrake need to pay attention to things in the high-end vehicles common to the electronic handbrake equipped, compared to the traditional mechanical handbrake, electronic handbrake appearance is simple and beautiful, easy to use. However, the electronic handbrake uses an electronic reel, which has a corresponding time during the tightening and releasing process, generally 0.5-1 second, slightly slower than the mechanical one. Although only 1 second, but the handbrake has not fully released it, the foot of the car's accelerator will step on the accelerator, this will also cause handbrake system aging, damage.
Fourth, the foot brake Note Foot brake is actually the same as the handbrake, but with the feet to control, the principle is the same. When using the foot brake, it is necessary to take care not to press down too much force. Because the foot has a large force, it is very easy to step on the foot brake, which will accelerate the wear of the handbrake cable and even break it.
Summary: As long as you drive out, you will need to use a handbrake. The hand brake system is used very frequently in daily use. The correct use of a handbrake can ensure long-term stable work. In particular, mechanical handbrake, some of the acute sub-car owners have not stopped it, the handbrake to pull up, and some people are careless, the handbrake did not put down to start driving, and these operations the brakes damage is very large. Good habits can reduce their maintenance costs, increase their service life, and at the same time ensure safety.
