Heres a tip for next time. Hit the rotors around the wheel studs...... becareful not to hit the wheel studs, it will losen them up from the hubs. Then when you put the new ones on you should sand down the wheel hubs to get all the rust and debri away from the new rotors otherwise they may sit awkardly and cause a brake vibration or warp the new rotors. Lastly make sure you clean the rotors with soap and water, then rough up the pads a bit before you throw them on. It helps the pads seat better. OH and put some brake grease, or perferably anti-sieze compound grease behind the rotor, between the rotor and the hub. You dont have to use alot just use a small paint brush and paint the grease on the hub between the studs, this will help the next time you do your brakes, they wont "stick" to the hub.
And congrats. Now you have to flush and bleed your brakes. But thats a leason for another day, baby steps first.
