I don't understand the use of either term.
One is brake = to slow down. It doesn't slow the bullet down and it doesn't break the bullet either.
We should just call it a recoil moderator.

I think it is supposed to brake (slow down) the rearward motion of the gun (after all, these things were used on actual guns (artillery) before people decided to put them on rifles) and the device is located at the muzzle end as opposed to being part of the hydro-pneumatic recoil system located at the rear of the gun. But that is speculation on my part. At least recoil moderator would be spelled correctly more often!
