Brad is a character from the 1982 movie Grease 2. Played by Matt Lattanzi.
During the talent show, The Prep-Tones were rehearsing in the shower room, and were ambushed by the T-Birds, who lashed them to the shower assembly. On command from Johnny Nogerelli, the T-Birds drenched their rivals and stole their jackets for their Prowlin' performance.
Brad and the Prep-Tones watched from the side-stage, dripping wet, as the T-Birds swept the boy's division. It could be speculated that Mrs. McGee was so bored by the Prep-Tones' performance, she ignored the fact that the T-Birds technically cheated by stealing the jackets.
Brad and the Prep-Tones were later seen at the Luau, dancing with Stacie & Gracie, dressed in Hawaiian shirts, brandishing red-yellow pom-poms. Later that night, Brad was one of the raft-bearers who had to carry the King and Queen Johnny Nogerelli and Stephanie Zinone in their ceremonial raft.
