I realy didnt have a thought about the M&G other then the first
things I look to when a problem arises is ;self inflicted
changes ;recent repairs, and ;operator confusion. M&G uses air and
the toad is a big electiral system modification to the bus. Drew's
post was full of good details, I wanted him to reveal more to the
readers who may have the solution. It sounds like RalphF has the
solution, and Drew will followup with a result. I just wish the
subject line was more descriptive as to help with a future archive
search.

Looking at the prompt to the problem (pushing the brake pedal)
Leroy was able to surmise the TwoPedal/BigToe theory. Since pushing
the pedal moves air and turns on electric brake lights, it may be
air or electric. I have no idea how the cruise or high idle works
knowlede of those systems would help solve his issue. I am not
confident enough to use CruiseControl to drive or use an air
operated high idle system to warm my bus.

The service brakes(prompted by driver brake pedal) in an air brake
system are pressure applied, without pressure the brakes are off.
The park brake spring is the one that needs constant pressure to
remain off. If the M&G brake away brake option fails, it may lock
the toad brakes up
