Technician A says surge bleeding is used alongside manual or pressure bleeding. Technician B claims it removes trapped air from the brake hydraulic system. Who is correct?

• A. Technician A only
• B. Technician B only
• C. Both Technician A and Technician B
• D. Neither Technician A nor Technician B

Answer: (A)

Surge bleeding involves creating a surge in the brake fluid within the system to help dislodge and remove trapped air bubbles that may be present. This method can be effectively used in conjunction with other bleeding techniques, such as manual or pressure bleeding, to enhance the overall process and ensure that the brake hydraulic system is free of air. Therefore, the assertion made by Technician A about surge bleeding being used alongside manual or pressure bleeding is precisely accurate and highlights an important aspect of brake maintenance. This understanding indicates that a technician must often employ multiple methods to achieve the best results in brake fluid management and air removal.

While Technician B also points out the effectiveness of surge bleeding in eliminating trapped air, the key focus of the question was on the application of surge bleeding, which makes Technician A's statement the one that directly aligns with the practice of bleeding brakes.
