How many hand pump strokes are required to fully charge brake accumulators from a depleted condition?

• A. 800
• B. 1000
• C. 1200
• D. 600

Answer: (B)

Brake accumulators are charged from a depleted state by a fixed amount of pumping because each stroke moves a precise volume and the system is designed to reach a specific target pressure after a prescribed number of strokes. The procedure defines that exact stroke count so you can bring the accumulators to full charge consistently, without guessing. After reaching that fixed count, you verify the charge with the brake system gauge to ensure the pressure is at the full-charge indication. If you stop too soon, the accumulators stay undercharged and won’t supply full hydraulic assist; if you go past, you risk overcharging or wasting effort. That single, manufacturer-specified stroke count is why the correct answer is the one that matches the standard charging procedure.
