The brake light switch failure rate is way too high.  I loose one as 
often as you do and have been using DOT5 for about 25 years now (Gee 
that long??).  I replaced one just yesterday.   I keep a spare and a 
7/8th wrench in the boot.

I always thought it failed from the heat as my brake light switch is 
mounted about 2 inches from the exhaust down pipe.  Next time the engine 
comes out I intend to relocate the brake light switch towards the front 
of the engine bay away from the exhaust system.
