Air valve(s) located at drivers entry step on M931A2?

[Excuse Me]

Are those air valves under the drivers entry step for the ctis or the anti lock brakes? Or,.........?

Thanks. I did search, and learned a lot of great new info on compressor governor issues and ppvs, but could not find what the valves are at this location on the M931A2.

Did you read the TM? Specifically the brake section?

Possibly to drain the water out of your air system.

Drivers side has the various air brake valves. The passenger side draincock valves are to drain the tanks.

Look at book TM 9-2320-272-23-5, fold outs (number 6 or 7 maybe) it has a complete air schematic. They are brake valves etc.

EDIT: Sorry, Just saw Drew posted just before me.

Good to know, so you could set the brakes that way?

I'm still learning how to use the TMs. I have trouble figuring out the separation from trucks with no abs and no ctis, and mine with abs and ctis. I'm getting better at navigating the TMS but still a long way to go.
