Former Knicks coach Larry Brown has already bolted town - and has moved his family from Greenwich, Conn., to Philadelphia, The Post has learned.

Brown, who is set to face Knicks owner James Dolan in high-stakes arbitration Friday in Manhattan, wanted his two children to return to their former school, the prestigious Episcopal Academy in Lower Merion, Pa.

But Brown's departure for his old haunt, Philly, where he coached a career-high six seasons, raises speculation he could soon join the Sixers' front office in an advisory capacity after he settles his contract with the Knicks, Marc Berman of the New York Post reports.

Brown's best friend in the league still is Sixers GM Billy King and Brown had a very strong relationship with Philly owner Ed Snider. The Sixers are coached by Maurice Cheeks, Brown's former Sixers assistant. When Brown bolted Orlando's pre-draft camp a day early after Isiah Thomas snubbed him last June, King, on request of Brown's wife, Shelly, flew home with him on a charter.
