Final answer:
The correct answer is not in the provided options; the described technique of smoothly and gradually reducing brake pedal pressure is known as 'trail braking' or 'tapering off,' which is a skill rather than a braking system.
The correct answer is none of all.
Step-by-step explanation:
The braking technique used to smoothly and gradually reduce brake pedal pressure at the end of a braking maneuver to help avoid abrupt weight transfer when turning at an intersection or into a curve is none of the options provided. What is being described is a driving technique often referred to as 'trail braking' or 'tapering off'. This technique is not a specific system but a skill used by drivers. The systems listed in the options like Anti-lock braking system (ABS), Electronic brakeforce distribution (EBD), Brake assist system (BAS), and Traction control system (TCS) are all various technologies that assist in braking, but do not strictly pertain to the gradual reduction of brake pedal pressure by the driver.
To explain this in terms of friction, when approaching a stop, easing off the brake pedal reduces the braking force, moving from
