cyclic gal and SP
Thank you for correcting my rather rash assumption that these brakes were a recent thing, this was based on the fact that I'd only noticed their mention in technical reviews of fairly new types and because I'd never noticed this kick-back behaviour before, possibly the earlier generation brakes weren't so powerful or the pilots released them just before the stop, which would seem like a sensible move.
There were some intersesting comments in this thread from last year (Note to self: I must use the search facilities before posting

It does seem like some kind of interlock would be a good thing, especially if it can be as simple as a line of code
