Saving Brick is something you can do within The Pickup mission of Cyberpunk 2077.
How to free Brick
After creating mayhem in the meeting area and climbing the ladder, then dropping two floors down, you should be in an area with a few enemies and two different rooms side-by-side but separate from one another. Between those rooms is a door that leads to where Brick is held captive.
You can scan the keypad and use Remote Deactivation to get through the door, or you can go into the room on the right side and open up the closed laptop. Go into Messages and look at the one titled only you guys know. It will have the code 9691.
Use that code to open the door.
Inside the room, there’s a detonator focused on Brick. Once again, you can use your scan and Remote Deactivation it, or you can return to the room with the laptop and look to the left. There’s the detonator on the table. You’ll want to choose Disarm charge in order to save Brick and not blow him up.
Enter the room and you’ll have a small “thanks” conversation.
