  I have just replace the master cylinder for the failed one I discussed last
week.  After I bled the brakes I noticed that the dash brake waring light was
not on as usual after a brake bleed.  Could it have been a miracle and the
circuits were balanced...not.  It seems that at some point the connection
between and the switch the wiring harness has become corroded enough to cause
the warning light not to go on. When I cleaned the connector the light worked
as usual.  I now am guessing that what happened was that the one of the brake
circuits failed, the light didn't work and when the second circuit failed I
was left with no brakes.  What is startling to me is that the brakes felt
absolutely fine, solid pedal, good braking...until the they failed.  I can't
emphasize much how important it is to check that PDWA operation.  If the
brakes had failed me in an unfortunate moment I could have killed some poor
pedestrian or done way more damage to me, my passenger, or the car than I did.
