Expert Reply:

Your TDE model LP7000 surge brake actuator will need to be entirely replaced as the master cylinder is no longer available for it. With this unique style coupler you will need either a Disc # DX63FR or Drum # DX53FR brake actuator which will need to be welded on. This will replace your entire actuator assembly and a portion of your trailers tongue.
