What type of braking system is characterized by high-pressure and low displacement?

The multiple-disk hydraulic brake system is characterized by high pressure and low displacement due to its design and operational principles. This system utilizes hydraulic pressure to transfer force from the brake pedal to the braking components, allowing for efficient and rapid braking action. The multiple-disk configuration contains several friction surfaces, which increases the braking surface area significantly without requiring large movements or displacements.

As a result, when the hydraulic fluid is pressurized, it can exert a substantial force to engage multiple friction discs simultaneously, leading to effective braking with minimal travel or movement, hence the term "low displacement." This makes multiple-disk hydraulic systems particularly advantageous in applications where space and weight are critical, as they can offer robust stopping power in a compact form.

In contrast, other types of braking systems might not offer the same combination of high pressure and low displacement, which is why this answer stands out as the correct choice.
