Recently, when I take off a little faster, or stops faster, my brake warning light turns on. (The circle with an exclamation mark, and Tarmac written on top) It's not all the time.. happens once every 2 days when I do a little spirit driving. Today, when I took off fast, the same thing happened but also with the handbrake light on too for a brief second.. then goes away..

I gotta take car back to get the recall done anyways, but wondering if this is a problem I need to see immediately? or does this mean my brake pads need replacement? I got about 16000 miles

 

sounds like the to much slack on the handbrake tension

 

Have you checked your brake fluid level?

 

It could be a number if thinks - ABS sensor fault, or some other sensor in the car that is tied into the car.

 

Your brake fluid is low (as the brake pads wear the level goes down).

 

ok thnx.. I'll go get my oil changed today and check the brake fluid.. see if that's the problem

 

Goffygrin is most likely correct, as your pads wear your brake fluid goes low. Here's how it's supposed to work:
As the brake pads wear, the caliper pistons will be more and more extended to keep the brake pad right up against the rotor. Since the pistons are extended, there is more volume for fluid inside your braking system, thus your fluid level drops. Manufacturers set a sensor in the fluid reservoir to set off an idiot light on the dash when the fluid drops to the point that indicates that the pads need replacement. Of course the problem with the Evo is that when the fluid gets low (but not quite low enough that you need to replace the pads yet) acceleration, braking, and/or turning can cause the fluid to slosh around in the reservoir and set off the sensor- very annoying.
The point of my long explanation? Check your pads. They might not need changing yet, but they probably will sometime soon.
