Turn signal problems - please help

[Fecal Extrusion]

I HATE dealers, and I don't yet trust anybody in town with my:
- mint cond. loaded 99 VW MK3 GTI VR6
- 60000mi, no mods whatsoever!

I'm having a problem, where any time I step on the brake pedal
it stops the turn signals from flashing, either direction and hazard
lights as well, as long as my foot is off the brake pedal everything
that should/can flash does.

Any ideas. somehow I'm not believing it's the flasher/relay, or else
the indicators wouldn't work regardless.
P.S. ALL the bulbs seem to be working.

FYI...
info i took from her helped me immensely,
so I will give back to the comminuty!!! : )
THANKS!

It turns out that BOTH my posted problems:
"Weird alarm problem..."
and "Turn signal problems... Please Help"
are both related, despite the alarm misbehaved for
weeks before the turn signal problem showed up...

THE PROBLEM WAS...
As Boschman pointed out in another post that
the Rear (left) tail-lights 8 Pin connector had a
corroded ground connection.

I was mainly intending to fix the turn signal problem,
and I cleaned and tinned the terminals, and the turn
signal problem went away. BUT in fixing that the alarm
now behaves properly.

SO. (and if you read my "Weird alarm problem..." post)
what I'm deducing is that, every time I armed/locked the
car, the module would flash the hazard lights, including
the (tail-light) like normal. And since the ground connection
was flaky at the tail-light, the bulb was trying to steal a lower
voltage potential (ground) from the alarm module, thereby
setting the alarm off, because of the weird sudden voltage
drop to the module.

I can't confirm my theory, but the alarm hasn't misbehaved in
a while. (...knock on wood!)
If I discover otherwise I'll update this, as I solve it!
