r0 complete this series on air brake equipment, it would make sense to iscuss certain of the main stoppages and dimes that can occur during a lengthy eriod in service. And since we have xamined the make-up and operation of each alve and unit, it should now be possible 3 avoid a lot of time-wasting effort, and rom the reported ailment diagnose the emedy with the minimum of delay and xpense.
Let us take a fairly common bad veather fault first: "Slow pressure build-up". ?uite a lot of time can be lost in detecting his fault as there are several causes, larticularly in below zero conditions. For xample, valve mechanism that has become ticky with long use but still working at lormal temperatures, can fail due to low emperature contraction of the body or ;asing, and only a strip-out will clear the ault.
