Its not really that hard. The rear brakes may need a speacial tool that you can get at most auto parts stores. Its a brake cube, you use it to screw in the pistons on the rear calipers rather than compressing them. You can use needle nose pliars as well. If the pistons have a flat surface rather than the noched surface that you would use the cube on then you can compress them. Other than that its really easy, just bleed the brakes and press and release the emergency brake when your done (this adjusts the pistons in the rear calipers).
