Handbrake can not be ignored to teach you DIY inspection and maintenance

【Car owner's car knowledge】Car handbrake is an auxiliary braking system, mainly when parking,It is set up to prevent vehicles from rolling by themselves.However, the handbrakeIt is not a "universal insurance", its effectiveness will decrease with the increase in usage. Therefore, car owners should regularly check and maintain the car's handbrake. The specific methods are as follows:

1.Determining the position of the handbrake handle

To check whether the handbrake is normal, you can first check the position of the handle of the car's handbrake.Usually, when the handle is lifted to the70%the handbrake braking system should be in the normal braking position, so before checking the braking force of the handbrake, you should first find out this70%The working point can be determined by counting the ratchets.

2.Check if the handbrake works

Drive the car to a slope with a steep slope and a good road condition (preferably asphalt), step on the brake, put the gear in neutral (if it is automatic transmission, hang it in N gear), and pull the handbrake handle to the determined position just now. work point location. Then slowly release the brake pedal, if the car does not slip, the handbrake is working well. This inspection should be done once on both the uphill and downhill positions.

3.How to adjust the handbrake

In the above inspection, if it is found that the braking performance or sensitivity of the handbrake is not ideal, it can usually be solved by adjusting the operating copper cable of the handbrake. There is an adjustable compensation mechanism at the connection between the bottom of the handbrake handle and the copper cable (generally covered by interior parts), and the length of the brake copper cable can be stretched by loosening the lock nut with a wrench. However, the adjustment mechanism of some cars is located at the bottom of the car. If it is inconvenient to adjust, it should be handled by professional maintenance personnel.

Precautions:Many people think that if the braking system fails, they can pull the handbrake to slow down. In fact, this approach is wrong. Because the handbrake mechanism is not precise, the braking force on the left and right sides is unevenly distributed. Pulling the handbrake at high speed can easily lock the rear wheel on one side, causing side slip, which is very dangerous. The correct way is to slow down by downshifting, and only pull the handbrake to stop the car when the speed drops.
