Brake booster leak

2014 ACE 30.1 on a Ford F53. Hydraulic fluid drips on floor of coach under the brake pedal. Is this a typical problem with the brake booster?

Sounds like you have a bad master cylinder.

I think the booster is air only, vacuum from the engine, a free with master cylinder

Not sure, but some larger vehicles have hydro-boost on the brakes which is powered by the power steering pump. I have seen brake fluid travel back along the pushrod and leak into the floor.
