Cable switch on this beastie had a fairly stout spring. Cutting half a
coil off made it work, and improved feel in the process. Cable is
thicker than the slots on the arm and the lever; a real bugger to get
back into place.

Just want stuff to work the way it was supposed to!

Most of those switches that I have seen over the years used a piece of
rubber for the switch "spring". Anyways, I'm not big fan of the cable
mounted switch. Even if they do work right, The compression required to
work them has an adverse effect on the brake operation. I think a lot of
the bad rep of the Loopframe TLS brake is because of cable issues. Some
of the aftermarket cables I've seen are really small diameter and wimpy.
I'm generally happy to ride without a front brake switch as long as the
rear switch is reliable. I always use the rear brake in tandem with the
front when I come to stop. I have always mean't to work out a
microswitch
set-up at the lever, but it hasn't become a priority yet.

Spent the evening futzing around with Giuseppe the Guzzi - lubed up
the
cables simply to pass the time. While at it, I noticed the
compression
switch on the front brake cable was inoperable...

Tore the cable apart to see what was the matter. There was an
aluminum
dust cover on top of the switch; felt that was limiting the ability
to
make contact. Cut it off - no closure. Checked continuity; had
power
to both spades. Tried tightening the snot outta the adjustment -
even
with TWO hands I could not make the contacts of the compression
switch
close.

I'm not a small guy; over years of restoration I've sheared some
pretty
big bolts simply thru grunt power. If I had two hands on the brake

there's a pretty good bet that the front end woulda locked up B4 the

contacts were closed.

So...I got to thinkin'...

Whipped out the dremel and cut off a 1/2 turn of the spacer spring
on
the switch. this was a gut decision, mind you - if it was wrong,
I'd
have to buy a new cable.

Put 'er all back together and...

Giuseppe LOVED it! brake light actuates with 1/2" of lever travel -
just
like it's supposed to. I suspect the switch NEVER worked - is the
true
with other bikes?

Pleased south of Pontiac,

Chuck.
