The Anti-lock Brake System (ABS) is the type of brake system that utilizes an electro-hydraulic control unit. ABS is designed to prevent wheel lock-up during braking, which can lead to skidding and loss of control. The electro-hydraulic control unit is a critical component of ABS, as it uses electronic sensors to monitor wheel speed and applies hydraulic pressure to each brake. This allows the system to modulate brake pressure and maintain traction during hard braking situations.

In contrast, standard hydraulic brake systems, disc brakes, and drum brakes do not employ an electro-hydraulic control unit in their basic configurations. Standard hydraulic systems primarily rely on hydraulic fluid to transmit force from the brake pedal to the brake calipers or wheel cylinders without any electronic modulation. While disc and drum brakes are common configurations that can be part of an ABS, they do not function with an electro-hydraulic unit independently. The presence of the control unit is what differentiates ABS in terms of technology and functionality, making it crucial to understanding modern braking systems.
