The  brake light on my Lumina (I know it's not a Ford product) did 
exactly the  same thing.  After doing some research, it turned out to 
be the turn  signal switch.  I have no idea why it was routed there, 
but it  was. 

Almost all cars, at least all cars that use the same filament for both  the 
brake and the turn signal lights, feed the brake lights through the  turn 
signal switch, so that if you are sitting still with the brakes on, making  a 
turn, the rear turn signal lights on that side will still flash on and  
off. The turn signal feed circuit interrupts the brake circuit and feeds its 
own  flashing power to it. 
 
So - the question is, do the turn signal lights still work on the Explorer? 
 - on the assumption that the same filament is used for both brake and  
turn.  If the turn signals work, it is the circuit feeding the turn signal  
switch that is bad. If neither the turn or brake lights work, it is  probably 
the feed from the switch back to the rear bulbs.
 
I hope you find it!
