I have seen write ups that state the Harley Davidson brake switch is low
pressure and DOT 5 compatible.   I have no details beyond those statements
and no experience with the HD switch.

 

Todays traffic dictates a faster reacting brake light switch and brake
lights; safety first.   When I installed cruise control on my Tiger, I
needed a mechanical switch on the brake pedal wire in parallel with the
hydraulic switch.

 

I always recommend installing a switch on the brake pedal.

If the switch isn't waterproof, and has an opening of some kind into the
interior, you can use a couple of CRC products. First spray contact cleaner
into the switch, preferably onto the contacts if they're accessible,
exercise the switch a couple dozen times to wear off the corrosion, let it
dry, and then spray in 2-26, which is an electrical contact
lubricant/protectant. This should slow down the oxidation process on the
contacts. Test with a meter to verify the switch is operating normally
again.

I've had yet another brake pressure switch fail. On my Alpine, I built a
bracket and made a mechanical switch. These all seem to go bad after not
long enough. 

 

Any thoughts on if a "bad" switch can be cleaned and fixed? Or if any
particular brand is better at lasting than another?  I don't feel like
building another bracket just now.

 

I also see I happen to have another new switch. But it's a single wire. I'll
have to look at the wiring diagram to see if that could possibly work.
Probably not.
