Power assist systems require inspection of what?

Power assist systems require inspection of what?

• A. Hoses, valves, and the fluid condition
• B. Battery age
• C. Spark plugs
• D. Exhaust system

Answer: (A)

Power assist systems rely on hydraulic pressure created and transmitted through hoses, valves, and the hydraulic fluid itself. Inspecting the hoses is essential because any cracks, bulges, leaks, or wear can cause pressure loss and sudden failure of the assist mechanism. The valves must function smoothly and seal properly; sticking or leaking valves can prevent proper regulation of hydraulic flow and degrade assist performance. Fluid condition is critical: contaminated, degraded, or low fluid level can impair lubrication and pressurization, leading to reduced or lost power assist. Items like battery age, spark plugs, or the exhaust system are not part of the hydraulic power assist system and won’t directly affect its operation.
