Without parking brakes, I'd have to use chalks.

Hydraulic parking brakes seem to work fine on aircraft ranging in size
from a PA-28 to an MD-11. I can't see any reason they could not be
used on a trailer.

What are chalks?? Is this another common language thing?

Possibly a spell checker thing, if using the "Dan Quayle Spell
Checker" plug-in.
Chalks are a bit like crayons, but some children don't like the taste
as much.
News of a hydraulic parking brake actuator to add to a hydraulic
surge brake system would be welcome.
