Question

1. technician a says that flare nut or line wrenches should be used to loosen or tighten brake line or tubing fittings. technician b says that open - end wrenches will surround the fitting’s nut and provide a positive grip on the fitting. who is correct? a. technician a b. technician b c. both a and b d. neither a nor b

Explanation:

Flare nut or line wrenches are specifically designed for brake line or tubing fittings as they provide a better grip and reduce the risk of rounding off the nut. Open - end wrenches do not fully surround the nut and are more likely to slip compared to flare nut wrenches. Technician A is correct as flare nut wrenches are the proper tool. Technician B is incorrect because open - end wrenches do not surround the fitting’s nut as effectively as flare nut wrenches for a positive grip.

Answer:

a. Technician A
