The working principle of the handbrake: through the brake shoe and the brake hub or friction plate and the brake disc friction clamping to achieve parking. It is used to stabilize the vehicle after the vehicle stops, and avoid accidents caused by sliding when the vehicle stops on the slope road.
The parking brake only brakes the rear wheel, and it uses two metal steel cables to pull the rear wheel brake plate to brake.
Under normal circumstances, when the handle is lifted to 70% of the entire trip, the handbrake should be in the normal braking position, before detecting the handbrake braking power, you need to find this point first, you can determine by the number of ratchet sound, 70% of this position is the effective working point of the handle.
