I am looking for advanced Shiurim online which teach Gemara in the Brisker fashion, does anyone know if any (preferably free) classes are available online?

You may wish to try the shiurim of R. Mayer Twersky or R. Michael Rosensweig on http://yutorah.org.
Try the series Talmudic Methodology by R' Moshe Taragin at the Virtual Beit Midrash.
