What creates hydraulic pressure in a brake system and how does it impact the braking performance of a vehicle?
Hydraulic pressure in a brake system is created when the brake pedal is pressed, causing brake fluid to be compressed. This pressure is transmitted through the brake lines to the brake calipers or wheel cylinders, which then apply force to the brake pads or shoes, ultimately slowing down or stopping the vehicle. The higher the hydraulic pressure, the more force is applied to the brakes, resulting in better braking performance and shorter stopping distances.
