Grab it with pliers and give it a wiggle. If it resists thread a long M6 screw fully into the boss, so you don't squish it, and escalate the pliers force, but be mindful that the steel is only 1 mm thick. Worst case, you can file through the brass sleeve to loosen it. Then apply a thin film of grease when fitting the brake arm, so it doesn't happen again (the brakes will also work better).
