Check the brake fluid level!
Or check the switch under the handbrake lever.

Subject: master brake light misbehaving

Hi all.
I have 91 vanagon with 2.2 Subaru Engine.  My master brake warning light on
the left side of the dash has started coming on....sometimes......Im not
sure how long its been doing it - I rarely drive the car at night, but I did
the other day and noticed it - now that I know its there I can see it in the
day, but its probably been going on for a while during daytime driving
without me noticing.  It flickers on only when the engine is running above
3000rpm.  As soon as I brake or put the clutch in the RPM goes below 3000
the light instantly goes off.  It is not speed related - I can do it at
idle.  The more I am above 3000rpm the stronger it comes on. I have checked
the fluid - it was a bit low, I topped it up but no change.  Also adjusted
the parking brake for correct operation. Im not sure if this is a standard
vanagon thing or something the PO monkeyed with during the 2.2 install.
Any ideas?
ThanksBrettGreater Vancouver, BC.
