Backup for dropping the gear

Cool! So if you lose your engine the plane helps you get back to the
ground quickly by extending the air brakes? Is there an override (for
those who fly over inhospitable terrain/water)?

The hydraulic pressure is probably provided by an electric pump

Ah...that makes a difference.

Furthermore, loss of pressure should only happen if there's a leak in the
system somewhere;

I can buy that (although my gear commonly "droops" after many checks) with
the emphasis on "should". (On farm equipment, the typical culprit is the
controlling valve.)

Is there a placard that says "Do not lose engine power in excess of max.
gear extension speed."?

There would be no need for such a placard.

Yeah, it looks like it would need to be "Do not leak hydraulic fluid in
excess of max. gear extension speed."
