Question

Two technicians are discussing the operation of the anti-lock braking system (ABS). Technician A states that if a wheel is in danger of starting to lose traction, the ABS responds by momentarily reducing hydraulic pressure to the brake on the affected wheel or wheels. Technician B states that the rapid modulation of brake pressure by a control valve in a given brake circuit reduces the braking load on the affected wheel and allows it to regain traction to prevent lockup. Which technician is correct?A) Technician A only
B) Technician B only
C) Both A & B are correct
D) Neither A nor B are correct

Answer 1

Answer:

 C) Both A & B are correct

Explanation:

                Regarding the working of ABS or anti lock braking system, both the technician A as well as technician B are correct in their own way.

               The function of ABS or anti-lock brake system  is to stop the wheels of the vehicle from skidding or locking up the wheels during braking process. When the brakes lock up when pressing the brake pedal on the event of loosing traction, the vehicle takes longer time to stop and the ability of the vehicle to steer is greatly reduced.

                   The anti-lock brake system prevents the wheel from locking up by monitoring each wheel with the help of a  wheel speed sensor. When the wheel starts to loose traction, the hydraulic pressure that is applied to the brake is reduced to stop the wheels of the vehicle from skidding.

Thus the both the technicians are correct.

Hence the answer is C) Both A & B are correct.
