technician a says that all bleeder valves must be located at the highest part of the caliper or wheel cylinder. technician b says that all bleeder valves have a hole in the center. which technician is correct?
technician a only
technician b only
both technicians
neither technician

Explanation:

For Question 11: Technician A is correct because depressing the brake pedal slowly and not to the floor prevents master cylinder seal damage. Technician B is incorrect as waiting 15 seconds between strokes is not a standard requirement for bleeding; the key steps are consistent pedal pressure and valve operation.
For Question 12: Technician A is correct because bleeder valves must be at the highest point to allow air (which rises) to escape. Technician B is correct because bleeder valves have a central hole to release air and fluid during bleeding.
