Just had all the brake calipers off and finished replacing all the guide pins on the brake calipers. While the coach was still up on jack stands with the wheels off I started the engine and tried to engage the high idle to get the air tanks back up to PSI, nothing happened. Turned off the engine and power switch, turned back on, restarted and still no high idle. Only thing I can think of is the parking brake was set with about 70 PSI in the tanks, maybe it didn't set enough to allow the high idle to engage. Just shooting in the dark here.

P.S. Darn those brake parts are big, you really realize it when they are off the coach and on the work bench.
