Not until the pressures in all these reservoirsare nearly equalized does the equalizing piston move to its full releaseposition and permit air to flow from the brake pipe, but when this doesoccur air from the brake pipe then completes the recharging of all thereservoirs up to normal brake pipe pressure. In this way all the airsupplied to the brake pipe through the engineers brake valve duringthe early stages of the release is effective in raising the brake pipe pres-sure and uniformly releasing all of the brakes. Graduated Release Cap in Direct Release Position. 119. In recharging after a service brake application, the auxiliaryreservoir pressure is increased by air flowing to it from the brake pipe only,no air being supplied to the auxiliary reservoir from the emergencyreservoir when the graduated release cap is in direct release , when the auxiliary reservoir pressure has b
