Place the ignition key on what I call, the "service" mode. Turn off the radio just in case. This should not turn the lights on the dash...or you went to far! You want to retract the the steering lock is all. This way, you can swing the wheels either way, without getting back in the car and possibly soiling the interior. If the suspension (knuckle) needs to be moved one way or the other, grab a wheel and swing it in the desired direction. Wear surgical gloves. Grease comes off these gloves better, if you need to wipe your hands.
The easiest way, is to elevate both front wheels off the ground. Removing the caliper bolts are a lot easier to remove and install now.
Remember for the next step, you are now going to push the pistons back in it's caliper. This will refill the master cylinder as this happens. If at one time, you topped off the M/C for a low level, (pad wear), now is the time capture any over flow of brake fluid.
Retract the caliper pistons if you have the correct tool. If not, try this. Since the rotors and old brakes are wasted (?), place a large flat blade screwdriver in between the brake pad and rotor. Push the pistons back inside the caliper. Don't cock the pistons at an angle but 90 degrees! Take it slow and careful. Use a shim for the one side you just retracted. Take the screwdriver to the other side, and do the same thing. If you don't shim the one side, the already retracted piston (s) will sometimes, "walk out" as you force the other pistons from the other side. Now send all the pistons "home." They should be flush with the caliper.
Clean the rotor carrier if there is rust build-up, or road grit. When installing the rotor, make sure both contact surfaces are debris free. This will make good contact for heat transfer, and the rotor should run "true" on the carrier housing.
The new pads should slide right in, and over the new rotor when installing the caliper back on the carrier housing. Remember to: "Torque" the caliper bolts to the proper specs!
Use brake clean to degrease the rotors. You know the rest of the assembly drill.
Burnish the brakes, and the job should be complete.
