Which brakes are powered by Hydraulic System 2?

• A. Inboard brakes
• B. Outboard brakes
• C. Parking/Emergency brake
• D. Nose landing gear brakes

Answer: (A)

Braking power is split between the aircraft’s hydraulic systems so each system can support braking if the other one fails. The inboard brakes—the ones closest to the fuselage on each wing—are fed by Hydraulic System 2. When you apply the brakes, System 2 delivers pressure to those inner brake assemblies, making them work. The other options don’t fit this particular distribution: the outer wing brakes are powered by the other hydraulic system, the parking/emergency brake is a separate function and isn’t tied to the inboard-outboard assignment, and the nose landing gear brakes sit on a different part of the hydraulic scheme than the wing inboard brakes.
