"Brake pads worn" warning light question

[Paul Meyers]

The brake wear indicator is a loop of wire embedded in the brake pad
itself. When the wire wears through, continuity is lost and the light
comes on. Other causes for the light coming on all involve loss of
continuity somewhere (bad connector, broken wire, etc.) The light can
come on intermittently when the wire is partially worn through.

Subject: "Brake pads worn" warning light question

Recently, I noticed the "brake pads worn" warning light on
my '92 100CS Quattro started coming on intermittently.  I
also noticed that when the warning light wasn't on, I could
get it to come on by honking the horn.  After replacing the
front pads (1/4 life remaining), the light still came on.
The rear pads have half the life remaining.  Any suggestions
on what else could be causing the warning light to still
come on when the engine is started?

Thanks for any ideas.
