the caliper is held on with two bolts...super simple to remove...to take out the old studs a hammer is gonna be your friend after you take off the rotor (which'll pop right off)...i had to replace all 5 of my rear studs on my old GT thanks to a bad wheel install from a shop. the reinstall is easy as well..get yourself a lug nut that you don't mind destroying and a nut larger then the stud so that it's like a spacer (about 1" is tall is what i use).
now put a few drops of oil on the teeth of the new stud and slide them through the back of the hub...on the front of the hub put your spacer on the stud (the large nut)...then thread on the lug nut..now use an impact to pull the stud through
it's a quick job once you get the feel for it after the first stud
