On my 2005 MK3 Pampera, the front switch is the normally closed type
like Neil mentions. The rear switch is the banjo bolt hydraulic type.
Neil's suggestions are spot on. If you pull the connectors from the front
switch, connect them together to prevent the brake light from activating.
Disconnect them and the light should turn on if working properly.
The opposite should apply if you are testing the rear switch.
Are you sure it is the brake light? Or could it be the running light?
Turn the headlight(s) off at the handle bar switch..
Sorry for no exact answer to your issue. Just got to chase the problem.

Ignore this info if you have hydraulically actuated switches (although they can be on if the internal plunger is stuck). If you removed the wiring from your switches, then there has to be a short somewhere causing your problem. Inspect the loom carefully.
