Which one of the following is NOT included in a typical anti-lock brake system?

• A. Hydraulic actuator
• B. Bead
• C. Anti-lock brake control module
• D. Wheel speed sensors

Answer: (B)

A typical anti-lock brake system (ABS) consists of several key components that work together to enhance vehicle safety by preventing wheel lock-up during braking. Among these components, the hydraulic actuator plays a critical role by controlling the brake fluid pressure to the brakes; the anti-lock brake control module processes data from the wheel speed sensors to determine when to modulate braking; and the wheel speed sensors monitor the rotational speed of each wheel to detect any signs of lock-up. The inclusion of a bead in the choices provided does not align with the function or structure of an anti-lock brake system. A bead is typically associated with tire construction or rim seating rather than the mechanics involved in the braking system. Therefore, it is correct to identify that a bead is not a component of a typical anti-lock brake system.
