Vehicle brakes. Principle of operation and operation

Car brakes are a necessary thing and they were not invented by cowards. Let’s talk about the brakes of the car and consider the principle of their operation and operation.
The principle of the brakes of a car

The principle of operation of any braking system is simple. The driver, acting on the brake pedal, transmits the force through a series of devices to the wheel brake mechanisms, which in turn act on the brake discs, pressing the pads to them and thereby stopping their rotation and, accordingly, the car as a whole.

Ideally, each machine is equipped with three braking systems: working, spare and parking. Spare, used when the worker fails, and parking – in the parking lot.

The most commonly used working. It consists of a number of devices that allow the driver to reduce the speed of motion until a complete stop. It includes brake devices (disc, drum), the main brake cylinder, the vacuum brake booster and the brake force regulator. Plus the highway with brake fluid.

Often used from wheel brakes are disc. The brake mechanism is located in the wheel arch, which requires additional channels in the body and drive for heat dissipation. Brackets of the disk brake mechanism are divided into fixed and floating.

When using a fixed bracket, the body is rigidly connected to the support. Two pistons are located in the body of the bracket on both sides of the brake disc and press brake pads against it, thereby creating a braking torque. The staples of the floating disc are divided into sliding and so-called Mark II. On both types, one or more pistons act on the inner brake shoe. The movable body of the clamp presses the second.

This scheme has a number of advantages: smaller dimensions between the brake disc and the arch, therefore this type of supports is suitable for suspension using small or negative values of the run-in arm; Reduced heat of the brake fluid due to the lack of a feed line in the immediate vicinity of the brake disc.
