Sounds like a caliper to me, might want to check the following: rubber part of the line. the mechanical part of the tounge….I have seen some of these that have been “tourqed” by an accidental jacknife of the trailer….it will hamper or stop the inner part from releasing… Take it to a brake shop and have them flush the system…take a good look at the brake fluid…..it will let you know (dark, debris) if the rubber is breaking down… GH @ Roger Stegall Professional Guide ServiceLast edited by Gary Harlan on November 30th, 2008, 3:51 pm, edited 1 time in total.Cpt.Gary Harlan (Harlo) USCG Liscd Fishing Guide Tishomingo, MS Roger Stegalls Professional Guide Service Sponsors: BassCat (of course!), Strike King, Falcon Graphite Rods, Gary Yammamoto Custom Baits
