Both statements are correct. Power brake systems can use a vacuum booster to increase the force applied to the master cylinder, which is what Technician A describes. Additionally, some power brake systems, particularly in some trucks and SUVs, use hydraulic pressure from the power steering pump to assist in braking, as described by Technician B.
