What component generates hydraulic pressure in a brake system?

The master cylinder is the component responsible for generating hydraulic pressure in a brake system. When the brake pedal is pressed, it pushes a piston inside the master cylinder, which compresses the brake fluid. This action creates hydraulic pressure that is transmitted through the brake lines to the wheel cylinders or brake calipers, depending on the type of brake system in use. This pressure actuates the brakes, allowing the vehicle to slow down or stop effectively.

Understanding the master cylinder's role is key to comprehending how brake systems operate. It not only initiates the braking process but also ensures that the hydraulic fluid is directed appropriately to engage the brakes at each wheel, thereby providing consistent stopping power.
