Message definition (Manual Cylinder Release)

It is not always desirable to have {{pll|Air Brake System Overview|air in brake cylinders}}. On {{pll|Rail Vehicle Types|vehicles}} that sat unused sufficiently long, brake cylinder is at atmospheric pressure due to {{pll|Cylinder Leaks|leaks in the system}}. However, on vehicles that were used more recently, brake cylinders could still be pressurized and have their {{pll|Brake Shoes|brake shoes}} pressed against the wheels. In situations where brakes need to be released, but waiting for a motorized vehicle to pressurize the system first is undesirable, such as in certain {{pll|Shunting|shunting}} maneuvers, or after a complicated {{pll|Derailing|derailment}}, sometimes the best option is to release brakes by manually dumping the brake cylinder pressure.

軔缸中存有壓力未必總是一件好事。一段時間未使用的車輛可能已經因為軔缸洩漏沒有軔力。但如果是剛解連的車輛，其軔缸仍可能處於加壓狀態而對車輪施加軔力。在有些時刻，例如調車時，如果可以不必等待軔管加壓就能鬆軔，將可以更快地移動停放的車輛。
