Not exactly a good solution... ;-)

The brake pad wear indicators are little wires within the pads. When the 
pad wears down, the wires get worn and becomes an open circuit. The two 
front pad sensors are connected in series and are grounded somewhere (I 
think by the right wheel).

The good solution to this would be to trace around the wiring and check for 
bad ground, bad connection, worn insulation, broken wiring in the pad wear 
circuitry.

The "kill the symptom, not the cause" solution would be to connect the two 
pins in each pad sensor connector.

My 1994 90S has ABS so I would think yours has as well. You should see the 
ABS light come on during start-up.
The only car I ever had with pad wear indicators was a 1985 5000CS. The 
wear indicator wires were about 6" long off the brake pad.
