Brake Accumulator 737 NG
The way I understand it, if the brake accumulator (ba) loses it's 1000 psi pre- charge the brake pressure gauge will read zero but if normal hydraulic pressure is available braking is unaffected. What I don't understand is why with a good pre-charge and normal hydraulics does the accumulator gauge read approx 3000 psi (normal hyd pressure) ? I would think then that with loss of pre-charge and normal hydraulic pressure the brake pressure gauge would read 3000 psi. Any ideas
