Cahc Digest, Vol 60, Issue 3; Brake Light Switch

[Bruce Goodrich]

Ultimately the Harley switch will fail also.  The only switch I found that
works is a 
mechanical switch sold by Street Works
http://www.watsons-streetworks.com/brake_switches.html
which sells for $40.  I have one on my '50 Ford Conv. and '50 Merc.  It has
an arm that swings
down and switches on the brake light.  Silicon, because of its absorbent
qualities, has a tendency
to weep past the seal on the normal brake switch and foul the connection.

Brake Switch For Silicone Fluid (DOT5)

There are benefits to using DOT 5 silicone brake fluid, including no
absorption of water into your brake lines and no lifting of paint when it
spills or leaks. Silicone fluid works great as long as you dono?=t mix it
with
any other type of fluid, and introduce it into a clean, dry system with new
rubber seals throughout. But a typical problem many LBC enthusiasts have
complained about is that this silicone fluid is many times not compatible
with
the hydraulic brake light switches used in our older cars. The switch may
work
for a while, but in a short time you may notice that it takes heavy pedal
force to turn the brake lights on, if at all.

Discovering that Harley Davidson uses silicone brake fluid exclusively in
their late model bikes, it seemed likely that a Harley switch should be
compatible with silicone brake fluid while also being designed to operate
with
the relatively light pedal force used with motorcycles. I went to the local
Harley dealer and purchased 72023-51D BRAKE LIGHT SWITCH KIT REAR. The pipe
threads are identical, and the Harley switch has the same 1/4 inch Lucar
terminals typically found on our carso?= stock switches. It works great as a
low pressure hydraulic brake light switch designed to be used with silicone
fluid, while it has a relatively stock appearance on our classic cars.
