Thomas,you mention that after manually adjusting the brakes they are ok for a while. Perhaps the pass side is backing off,like the self adjuster is not staying put??? Does the driver's side indeed lock up?? as in it skids with little pedal pressure on gravel,etc.If this is the case,I would think a leaking cyl has soaked the shoes. I would pull both front hubs off and have a peek. Stan in Montana __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com
