The red BRAKE light is related to the brake sensors; the sensors are designed to trip when the pads get down to a certain thickness (the sensor wears down with the pad and the connection eventually breaks, triggering the light). The sensors also trip however due to heat.

I concur with ashmostro; get the pads replaced and the sensors while you're at it (sensors are cheap). The rears might be OK (the front brakes do most of the work), but double-check. I'd also recommend a brake fluid flush, especially if it's been a while since your last one. Boiling the brake fluid (and just time in general) reduces its effectiveness. Consider going with high-temp brake fluid, if you're going to be driving the car hard. It won't boil as easily.
if pad life is okay just change the sensor. It really depends on driving. If you're tripping the traction control, rear pads will wear much much quicker.
