Which of the following is NOT a definition related to brake systems?

Dynamic braking refers to a method of slowing down a vehicle using an electrical or mechanical system that converts motion into energy, which may not be directly associated with traditional brake systems. It often applies to hybrid and electric vehicles, utilizing the vehicle's motors to assist in braking. While dynamic braking is a recognized concept in vehicle operation, it is not one of the standard definitions that typically relate to the fundamental components and functions of conventional brake systems, such as the service brake system and pedal reserve.

On the other hand, pedal reserve pertains to the amount of additional movement in the brake pedal after the brakes engage, ensuring the driver can still control the vehicle effectively. The term service brake system describes the primary brakes of a vehicle used for day-to-day stopping. Stopping distance refers to the total distance required for a vehicle to come to a complete stop, which incorporates factors like perception time, reaction time, and braking distance. Each of these terms is closely related to the mechanics and operation of brake systems, emphasizing why they are commonly defined in the context of vehicle safety and operation.
