The wheel/brake assembly’s function is to provide braking by housing the braking components right on the wheel. When you apply the brakes, hydraulic pressure is directed to calipers that squeeze brake discs attached to the wheel, converting hydraulic energy into friction to slow and stop the aircraft during landing rollout or rejected takeoffs. This assembly also supports the wheel itself and connects to the landing gear structure, but it is not responsible for steering; ground steering is usually accomplished by the nose gear or a separate steering system. The landing gear doors are distinct components that cover the wheel when retracted, not part of the braking function. The master hydraulic reservoir belongs to the aircraft’s hydraulic system as a whole, not to the wheel assembly. So the correct concept is that the wheel/brake assembly houses and operates the braking system on the wheel.
