DISTRIBUTING VALVE DEFECTS
140. Q. If the locomotive brake released with the automatic brake valve in lap position, where would you look for the trouble?
A. Would look for a leak in the application cylinder pipe or in the application cylinder cap gasket.
141. Q. If the brake remained applied in lap position, but released in release or holding position, where would you look for the trouble?
A. Would look for a leak in the distributing valve release pipe.
142. Q. If the distributing valve release pipe and application cylinder pipe were crossed, what would be the effect?
A. A brake application made by the automatic brake valve cannot be released by the independent brake valve.
143. Q. If the safety valve leaks, what will be the effect?
A. This may prevent the brake applying, and in an independent application if the brake does apply, it will release when the brake valve is returned to lap position.
