Seagrave Fire Apparatus (Seagrave) is recalling certain model year 2011 and 2012 Marauder II pumper emergency vehicles, models TB70CM, TB50CL, TB40CL, TB70CX, TB70CL and TB70CO manufactured from November 23, 2010, through October 22, 2012. These vehicles are equipped with Meritor axle assemblies that were built with disc brakes using MGM J24 series air brake chambers. In the affected axles, the brake chambers may leak pressure allowing the parking brake to drag when it is supposed to be released. Brake dragging could lead to overheated brake components.
