Explain the working mechanism of a hydraulic brake system with a figure.

Question

Accepted Answer

In a hydraulic brake system, the pipe connecting the master cylinder and the brake cylinders is filled with special brake fluid. In four-wheeled vehicles, the piston of the master cylinder is connected to the brake pedal; in two-wheelers, it is connected to the brake lever. Brake cylinders are located at the wheels, and their pistons are connected to brake pads or brake shoes. When the driver applies a small force on the master cylinder's piston, the pressure created is transmitted equally through the brake fluid, and a large force is generated on the piston of the brake cylinder. This large force presses the brake pads against the wheel disc, stopping a fast-moving vehicle almost instantly.
