His brother Ryan Pemberton was Mark Martin's crew chief in 2007. Martin and Kevin Harvick were battling for the win on the final lap of the 2007 Daytona 500. The race ended under caution flag when a big wreck happened on that final lap. Robin Pemberton determined the exact moment that the caution flag was displayed, which resulted in Harvick being declared the winner. "We [Robin and Ryan Pemberton] keep the business part separate," Ryan Pemberton said. "We don't put ourselves in position to do that. I don't call him to talk to him about it. I don't ask him any questions."
