question 4

technician a says that the brake pedal should be depressed with as much force as possible during the normal bleeding procedure. technician b says that the brake pedal should be pumped rapidly during this manual bleeding procedure to force the air down toward the bleeder valve(s). which technician is correct?
technician a only
technician b only
both technicians
neither technician

Explanation:

For Question 3: Bleeder valves often have tapered seats; a controlled shock (e.g., light tap) can break corrosion/tape seal without damaging the valve. A 6-point wrench distributes torque evenly, preventing rounding, and steady torque is preferred over excessive force. Both methods are valid.
For Question 4: Normal bleeding requires slow, steady pedal depression (not maximum force) to avoid aerating fluid; rapid pumping traps air instead of forcing it down. Neither technician’s statement is correct.

Answer:

Question 3: Both technicians
Question 4: Neither technician
