Most likely cause of the issue is some corrosion/dryness/wear where the break lever and piston rod on the master cylinder meet.
Remove the lever and clean the end of the lever and the end of the piston rod. (I use a plastic kitchen scrubber)
Apply red rubber grease to the ends and put it back together, that should sort it.Replace the brake hoses as they have softened with age causing the increased travel you mention
