Took me longer to jack her up and take the wheels off than to change the pads, front and rear. A piece of cake, very easy, are you using GM ceramics? The only thing i did once i changed all the pads, with car off. Gently apply pressure to the brake pedal several times till you feel the pedal firm up. Takes a few days of driving till the pads seat in and the pedal firmed completely for me. Changed mine with only 200 miles on my 04 Z, hated the wheel dust. The only thing you might have to do is soak the caliper bolts with some penetrating fluid if they are stubborn. Mine loosened right up because they were new, good luck.
