I was wondering how hard it is to change the rear brake pads on my 2006 Mazda 6 (3.0). I would like to change them myself and save some cash. I've done front disc brakes before but I hear the rears are slightly different.

I know the caliper pistons need to be TURNED back into the bore and not pushed back like the fronts. Is there a special tool I need for that? My other concern is the Ebrake. Do I need to deal with that to change them?
