I wouldn't say 'cannot', but on my DG1000 the brakes are hard to get on
and off the overcenter lock at high speed. Due to wing flex I expect. Hard
enough that I have done a high speed final glide holding the brakes closed
because I couldn't get them locked. 'High speed' would be something over
100 knots.

I noticed the same thing in a Libelle 201 when I tried using the brakes
at high speed.


So all of that begs the question, "Did you reduce the load on the wings
momentarily in order to reduce the flex, and therefor lighten the force
necessary to change your configuration?"

This stuff _may_ be rocket science, I wouldn't know--never having been
in a rocket.
