This happened to me about a year ago (1997 E36 318i). There is an easy test
for this condition before you go to the dealer or start tearing it down
yourself. Find a nice empty chuck of freeway and set the cruise control,
then tap the brakes. If the cruise disengages, your pedal switch is OK. If
not, then it's the switch.

In addition to the brake pedal switch suggestion, you might also want to
check the wiring loom. My 93 E36 recently lost the brake lights. Then a day
later the license plate lights. Then then the fog lights. Then I lost power
to the windows and central locking, and finally the alarm. Discovered that
all the wires were breaking and shorting in the part of the loom that is
exposed at the side of the boot/trunk - years of opening and closing had
caused them to split.
Follows...more of that fine German engineering. I guess it never
occured to them that trunk lids will need to be opened and closed
over time. I guess I'm about due for the brake pedal switch failure..
glad I read this thread.
