Rear wheels. The handbrake of a car generally controls the rear wheels. In general, it is connected to the rear brake pads by a steel wire, so it plays a role in controlling the rear wheels rather than the front brakes, mainly to prevent the vehicle from self-propelled when parking.
There are two brake systems for cars. We often say foot brakes and hand brakes. Recently a friend asked a question. I said I wanted to know if the foot brakes of the car were front or rear wheels. In fact, in an ordinary family four-wheeler, the foot brake acts directly on the four wheels. Because if the front wheel is braked separately, the direction of the vehicle may be out of control, and the direction of braking cannot be ensured when braking.
On the other hand, if the rear wheel is braked separately, the rear wheel will lose adhesion, and it is likely that the butt and side slip will occur on the car. First of all, the difference between foot brakes and hand brakes lies in the different braking environments. Foot brakes are often used in driving, foot brakes are called parking brakes, and hand brakes are only needed when applying parking brakes.
2. Secondly, the hand brake and foot brake control caliper use different methods for braking. The foot brake generally acts on the four wheels, while the handbrake mainly acts on the rear wheel. 3, the brake principle is different. The foot brake is transmitted to the hydraulic pressure through the mechanical force of the brake pedal, and the hydraulic pressure of the brake oil is transmitted from the pipeline to the brake of the brake disc, the braking force is large, and the control is simple and labor-saving. The hand brake brakes brake by connecting the pull cord to the rear brake pads.
