I had the exact same issue with my brake light switch, and tried to fix it with hose until I realized all I needed was to adjust the master cylinder push rod. Doesn't need to be turned much to move the pedal are quite a bit to the 13/16 spec toe-board clearance. Of course I had bought a new switch in the process, and now I have 2.
