What component provides steering assist in most buses?

Explanation:
Hydraulic power steering provides steering assist in most buses. The power steering pump, driven by the engine, pressurizes hydraulic fluid that helps move the steering gear. This reduces the effort needed to turn the wheel, especially at low speeds or when the bus is stationary. The other components serve different roles: the alternator supplies electrical power, the brake booster uses engine vacuum to aid braking, and the air compressor provides compressed air for brakes and other systems.
