My Big Country has an electric bedroom slide with cables. Recently I noticed that on the bottom right side of the slide 4 of the 6 screws holding the cable bracket to the slide have been sheared off. The bracket is now at an angle. Is the cable always under tension? Can I just remove the bracket and work on the screws? Any tips on how to remove the screws would be apprciated they are sheared off level. Can I just replace the bracket in a slight different location?
