A hydraulic brake system is being discussed. Technician A states that brake fluid must have a high boiling point since brakes create a lot of heat. Technician B states that hygroscopic means that brake fluid will not absorb water. Who is correct? a. Technician A b. Technician B c. Both Technician A and Technician B d. Neither Technician A nor Technician B

a. Technician A<br /><br />Technician A is correct. Brake fluid must have a high boiling point because brakes generate a significant amount of heat during operation. If the boiling point is low, the brake fluid can vaporize, leading to brake failure. Technician B is incorrect because "hygroscopic" means that brake fluid can absorb moisture from the air, which can lead to corrosion and contamination of the brake system.
