The 33-year-old midfielder is set to start training with The Valiants next week, having previously received permission to train with Wrexham and Crewe Alexandra in an effort to stay in shape after being frozen out by boss Kenny Jackett.
"Dave Brammer is coming to train with us next week," confirmed the club's chief scout Ray Williams to The Sentinel newspaper. "He has spoken to myself and to Dean Glover and he is really looking forward to playing football again for Port Vale."
