Handbrake use precautions

Handbrake is a very high rate of the system, reasonable and correct use in order to make the future easier to use, especially for the largest amount of mechanical hand brake, the better way to use the right, do not stop it Hand pull up, this practice is indeed not necessary. Save the point with, to ensure its good use of the effect, for the safety is very important, but also to extend the adjustment cycle to reduce the cost of repair and replacement.

Precautions for use

1, mechanical hand brake

Avoid getting too tight

For the most common mechanical hand brake, the first thing to note should not be busy every time when the car pulled up, with particular attention not to pull the head, because the metal is too long stretched or stretched for a long time will accelerate the deformation, resulting in accelerated handbrake Pull the brake fade. The correct approach is to pull the handbrake until the rear wheel after the death of 1-2 cells to mention, to ensure that no car can be.

If it is parked on the ramp, it is not recommended to use a hand brake to fix the car, because doing so will allow the handbrake to withstand too much braking force to speed up the handbrake wear. The correct way is to stop the car after the first fixed with a handbrake, and then find some reliable bricks or other objects under the tires in the tire until the wheel fixed firmly, the release of handbrake to force the transfer to the four wheels, pull the handbrake again, let Wheels and handbrake common force. If you are not assured, you can move the shift lever into a block or reverse gear, so you can do multiple insurance. But the editor here or to remind, not a last resort, do not recommend parking on the ramp, so how much will accelerate the wear of some parts of the vehicle.

After the winter snow and ice weather, try not to use handbrake. We often encountered in the snow after the traffic, the fender inside the silt will sink a lot of snow, the snow may be covered to the hand brake line, to freeze it, it is possible to start again because the hand brake can not be released and can not drive The In addition, after the car wash in the winter should also pay attention to this problem, if you can not handshake on the cable in time to clean the water, then do not pull the handbrake when stopping, with gear or brick pad wheel and other methods instead of hand brake parking.

Pedal parking system is also a "handbrake" of a, but is to use the pedal to control, often appear in the high-end models, a large number of models have Camry, LaCrosse, Mercedes-Benz variety of models. The use of this handbrake need to pay attention to the point is not mentioned above, do not every time to depress it, because the foot of the great strength, it is easy to "hand brake" step deep, so the life of the line is very negative , Even with the feet, but also intention to control a little effort, do not be so ruthless.

Handbrake in certain conditions can also play a role in helping to escape. If you are driving a rear drive or a four-wheel drive, when the rear wheel encounters slipping and lying on the nest, while your car is a car with a hand brake models, then you can use the handbrake for the rear wheel brake support The principle is to imitate the work of the differential lock, the two rear wheels to exert braking force, to limit the rotation of the side of the wheel rotation, the power "hold back" on the side of the wheel with the adhesion of course this action only to meet The following conditions can be achieved: rear drive, mechanical handbrake, side of the wheel with adhesion.

For the mechanical hand brake, the use of a period of time after taking the time to check whether the effective parking, it is recommended once a year. The car parked in a slightly angle on the ground, waiting for a slight slip car, the hand brake a grid one. Lattice pull up until the car can be fixed if the point is relatively high, handbrake almost pulled the head of the car was stopped, it is recommended to repair the shop to adjust the hand brake to prevent the use of the accident.

Electronic hand brake

Electronic handbrake is a simple and beautiful appearance, easy to use configuration, the end of the car more than the common configuration, but the electronic hand brake response speed is relatively slow. We hand to pull the handbrake time is probably not more than 0.3 seconds, and the human control is more flexible than the electronic control, and start the electronic handbrake need to have a brake on the premise of action, and the key response time (to avoid misuse), and The motor runs too long for about 0.5 seconds. Even when the throttle, the electronic hand brake automatically lifted, this action is also somewhat unexpected.

Some models of electronic handbrake also auxiliary emergency braking function. If the extreme situation in the process of driving, the operation of electronic hand brake button, you can brake the vehicle, this situation is somewhat complicated. First of all, we have to analyze this extreme situation, if the driver can not control the brakes (brake pedal failure, novice no brake awareness, the driver fell asleep, etc.), by pulling the hand brake button, the vehicle will be an emergency brake, The brake is not a mechanical brake hand brake, high-speed case, the emergency brake is through the ESP control unit to slightly less than the full force of the brake on all four wheels for hydraulic braking, and when the vehicle near the static state, Electronic handbrake to slow down or parking. For example, the mass of the electronic hand brake in the speed of 7 km per hour or so is the case, and only when the speed of 7 km per hour or less, is directly imposed on the car brake brake. Even if the vehicle accidentally flameout (the circuit is still connected), the function is still valid, of course, the brake lines and circuits can not be destroyed. According to this situation, we can also draw a conclusion: want to move through the handle of the children's attention to the tricks, and electronic handbrake is unable to make the flick of this action.

Automatic car first pull the hand brake and then hanging P block

For the automatic transmission at the same time with the electronic hand brake models, in the slope with the ground on the parking, we must first pull the hand brake will be fixed, then the gearbox into the P block, to reduce the burden of the transmission, To prevent the P block trivial latching can not be properly unlocked. In addition, even if it seems to be flat road situation, it is inevitable that some difficult to detect the small slope, the other automatic transmission models in the hanging when the block when the block will "wore" car, then pull the hand brake did not release the brakes directly linked P block, then the P block of the trivial buckle will be rivalry, over time will cause unnecessary wear and tear.
