This is a how-to on cleaning the abs sensors in a 2006 STI, but I am fairly certain the process is the same for all years. The reason you would want to do this is because these sensors get extreme dirty and can cause binding on low speed turns(they register speed and if all sensors all not on the same page, binding can occur). I experienced a lot of binding and this solved the problem, for the most part(all STI's bind a little according to the owner's manual)
Time required: 1 hr, tops
Tools needed:
Jack
Jack Stands
Socket Wrench
12mm socket
First break loose the lug nuts on the wheel(s) you will be doing first(I know my wheels are filthy).

Next jack the vehicle up at a solid point. For the front, I jack it up at the indention underneath the side skirt, and for the rear I jack up the rear diff. Then maneuver the jack stands into place, all without hitting your roommate's 300zx.

Next loosen all lugs and take the wheel off

Next, locate the wheel sensor behind the rotor(it has a cable, not the brake line, attached to it)

Loosen the 12mm bolt holding the sensor in.

Take the sensor out a see how dirty it is. I cleaned mine with a shop rag and no cleaning solution, so as not to screw up the sensor.

Those were the sensors on the front, the rears are a lot longer, and dirtier as shown here.

And cleaned.....

Reinstall in reverse order and you are done. There are no torque specs for the 12mm bolt, so 'good-and-tight' is what I did.
