Peter,

You explained during the seminar that the system which includes an assembly installed on the bus, and a veturi type assembly which is installed on the toad is connected to the bus braking system, and as such uses no air unless service brakes are applied.

Please help us understand how a broken fitting could cause ANY air to be heard, and / or how the bus would have trouble airing up due to a broken fitting.

We can remove the air hoses for our service brakes and never have any air escape until those brakes were applied. I am interested in the set up for my toad, and I would like to know exactly what happened (apart from a broken fitting).
