How do the wheel brakes receive hydraulic power?

The wheel brakes receive hydraulic power directly from the master cylinder, which is a key component in a hydraulic braking system. When the driver applies pressure to the brake pedal, this pressure is transmitted to the master cylinder, which then generates hydraulic pressure in the brake fluid. This hydraulic pressure travels through the brake lines, allowing it to activate the wheel brakes effectively.

The design of this system ensures that the force applied at the brake pedal is amplified and distributed evenly to each wheel, resulting in efficient and responsive braking. Understanding this process is crucial for recognizing how hydraulic brakes function and the importance of maintaining the master cylinder for overall brake performance.
