Rich:
I experienced a similar problem on my MKII using silicon fluid. I replaced
the switch and the problem reoccurred.
After some investigation I found that the switch was indeed working but it
would not pass sufficient current to light the brake lights: i.e. it was a
high-resistance switch. I surmise that the switch is affected by silicon
fluid. My solution was quite simple - I installed a relay that is triggered
by the brake light switch. The relay carries the current and the lights work
fine. I have been using this solution now for going on 6 years with perfect
reliability.
Cost of the solution: approx $5. Time to complete: approx 30 minutes. I
located the relay on the horn-hole cover plate I fitted to the car to
resolve overheating problems.

I just noticed thar my MKII now required very heavy pressure on the pedal to
turn on the brake lights. I have silicone fluid in the system now, would
changing back to GTLMA, and or, replacing the brake light switch solve the
problem. Or is Ron Fraser's post to change to a mechanical switch the way
to
go?
Thanks Rich
