The pilot reported that he had taxied through loose snow and slush at the departure airport. The subsequent flight and landing were in sub-freezing temperatures. On touchdown at the destination airport, the airplane veered to the right. The pilot applied left rudder in an attempt to correct for the veer, the airplane then veered sharply to the right, nosed down, and impacted a snow berm. The airplane sustained substantial damage to the left wing. Postaccident examination by the pilot, found the right brake still locked by ice and the left brake free. He then disassembled the right brake, and no mechanical anomalies were found.
