Brackenfur was made a warrior before Thornclaw because he was older and had been an apprentice for a longer period of time, demonstrating more experience and readiness for the warrior role compared to Thornclaw. Additionally, leadership decisions in warrior cats are based on a variety of factors including skills, abilities, and the needs of the Clan at that time.
Brambleclaw became a warrior in the book "Warriors: The New Prophecy: Midnight" by Erin Hunter.
