Wuling light front brake and hand brake are very easy to use, but the rear brake is not good. What happened?

First, due to the long service time of the hand brake lacing, the lacing will become longer due to long-term tension and will not return to the predetermined position. You can try to adjust the adjusting nut of the handbrake until the handbrake lever and the stopper are close together. The clearance should be as small as possible, about1mm. ..

Second, the professional name of the handbrake is auxiliary braking, which is different from the principle of braking. It is connected to the rear brake shoe with steel wire rope to brake the car. Long-term use of hand brake will lead to plastic deformation of steel wire. Because this deformation is irreversible, long-term use will reduce the utility and increase the stroke of the handbrake.

Thirdly, there is also a return spring used in conjunction with the handbrake. When the handbrake is pulled, the spring is elongated; When the handbrake is released, the spring returns to its original length. When the handbrake is used for a long time, the spring will deform accordingly.
