Too easy
Just jack up the car, remove the rims. first you need to make room for the new brakes, so take a pry bar or a big screwdriver and place between the brake pad and the rotor, pry these two apart gently until there is enough room in between the caliper and the rotor for the new brakes... this takes a little while. after you have enough room for the new brakes there are two bolts on the back of the caliper assembly, they hold the two piece caliper assm. to each other... they are the bolts that go through the little rubber boot. just remove the bottom bolt, and rotate the caliper up, remove the old brakes, put in the new ones, and then rotate the caliper back down to where you can get the bolt back in.... good luck, and if you have any questions, please ask.
