Do all other suppressors do this as well, if we're looking at the recoil vs sound.. just throwing it out there.. again, I think its great to have someone walk the walk in this subject...

Internal brake is a moot point, 3rd form physics will tell you recoil is a result of mass x velocity.
Mass is projectile mass and gas mass from powder burn.
A suppressor can slow VELOCITY of the gases by EXPANSION so LOWERING EXIT PRESSURE and reducing recoil to an extent,BUT all that gas still has to exit inline with the bullet! Energy can neither be created or destroyed only directed .

If it was possible (its not)to direct all gas out at 90 deg to the muzzel the only recoil would be as a result of the bullet(mass) being driven at X velocity

If you can direct that high pressure gas rearward it is going to start to counteract the mass of the projectile heading forward to an extent.
Simple really

Finding the optimum angle/portsize/no of ports in a brake (to suit the chambering) is not so simple
