During an encounter with a brute, shoot off either of his arms by staisising him, and aiming for his shoulder. Once the arm is off, back up about 8 "steps" (roughly) and wait, the brute will launch a pod out of his chest at you. Just catch it with kienisis and the achievement should unlock. Refrence the video below for further clarification.
*This video also shows how to unlock the "Brute force" achievement*
