Brick wants to do three things, which are to fight the Sheriff, get paid and blow stuff up; all of these can be done by going after the bank. When you go to check out the bank, you see that you can't open the vault door, so Brick has a plan to put into motion. The first order is to find some laxative, which is on the roof of a nearby building.
In order to get to it, you're going to have to jump off of the roof of another building that is next to it. It'll be in the toilet that's on top of the one building. The next thing on the agenda is finding some explosives, which are in the possession of someone named Mad Dog. Using the elevator in the little valley with the Skags will make it quicker for you to reach the area with Mad Dog.
Mad Dog is nothing special and should go down rather swiftly, so loot the explosives he drops. Head on over to the next waypoint to place the bomb, then coat it with the laxative. After everything is over, dig through the skag pile to find your final explosive that you'll use to blow open the vault. Once you reach the bank vault and place the explosives on the door, some enemies will spawn.
You don't have to kill them, but it might make it a little easier to loot the safes inside without your body becoming Swiss cheese. Once it's clear, loot the place and then head to the next marker to exit the town. You'll need to hide the evidence for now, which will be in three spots, while the Sheriff sends her men after you. These men are nothing more than the Armored Skag Riders you've encountered in the one area of Lynchwood. The mission will be over once you hide the last piece of evidence.
