In a closed hydraulic brake system the hydraulic pressure does what?

In a closed hydraulic brake system, hydraulic pressure is generated when the brake pedal is pressed, compressing the brake fluid within the system. This pressure is transmitted uniformly through the fluid to the brake calipers or wheel cylinders, causing the brake pads or shoes to clamp down on the brake rotor or drum. This action effectively slows down or stops the vehicle. The closed nature of the system ensures that the pressure remains consistent and efficient throughout the braking process.
