Desperate! Help me find a 1975 CB750 brake switch.

Gentlemen, I am in a bit of a pinch. For the past year and a half I have
been trying to find a replacement for a 1975 Honda CB750 brake pressure
switch. This switch taps into the front hydraulic brake line via a tee
fitting. When the front brake is applied, pressure in the brake line closes
the circuit and illuminates the rear stoplight bulb. I have taken some close
up pictures of the part and posted them on my website at the following link:

After more than 30 years of service, this factory original pressure switch
finally called it quits. Attempts to revive the switch with solvents failed.
I searched for a similar part at a Harley Davidson dealer but they were
unable to provide a suitable replacement. Furthermore, there are no part
recycling yards near me.



My mechanic suggests replacing the entire brake line assembly with a modern
system. However, I am resolved to preserve the motorcycle's authenticity and
therefore reluctant to permit a modification on that scale. Is there an
online parts supplier or a phone or mail order service that can lead to a
replacement for said elusive switch? If you know such a service or if you
can offer some general suggestions, please send an email to:







I am also willing to pay a reasonable fee to any person who can successfully
track down the correct part.



Thanks, Kerry

The wondrously distinctive "Ponch and Jon" stylings of this Honda can be
attributed to the original and single previous owner. You guessed it, a
California Highway Patrol officer.

 

Loads of Hondas used the same switch. I'm amazed you can't find a used
one - hell, I've just sold two.

 

I don't know if you've already found these sites, but you could look into
Retrobikes (http://www.olypen.com/retro/)
or David Silver Spares (http://www.davidsilverspares.co.uk/)

Good luck!
