AIR BRAKES 141 Release and Charging Position Fig. 118 shows only those parts and ports which are operativewhile the brake is being released and the pressure chamber andemergency and service reservoirs are being charged. Charging Empty Equipment. In charging the empty equip-ment, air from the brake pipe entering the control valve at the pointindicated passes to chambers B and A and forces the equalizing andrelease pistons of the equalizing portion, with their attached valves,to release position. Brake-pipe air then passes from chamber B,lifting the equalizing check valve, and by way of the
