I’ve about ‘had it’ with hydraulic brake light switches!
Around four months ago the hydraulic switch quit in my Speedster… The guy behind me in traffic was good enough to stop me and let me know that I didn’t have brake lights… Bad switch!……Today, I took my ‘63 Avanti in for an inspection sticker… and once again had no stop lights due to a failed hydraulic switch…...
I replaced the hydraulic switches in both cars… however, if this happens again, I’m going with a modern mechanical brake light switch, as used in later Avantis and many other cars.
