Running boost gauge off brake booster?

Was randomly looking at threads on here. Wouldn't mind installing a larger boost gauge.

Figured I would have to run a hose from the motor to the dash, a pain.

There are several threads on here that say you can run the boost/vacuum line off the brake booster???

Is that even possible???

I can't believe that the brake booster sees pressurized air from the path of the turbo...

I always thought brake booster was powered by engine vacuum.

What am I missing here?

Is there a way to add a larger VDO boost gauge that doesn't need to rerun a pressure line to the motor?
