If you just change the pads and rotors you probably won't need to bleed the brakes. Once you change replace the calipers you will have to bleed the air out.

 

Thanks for the heads up. After buying all the tools I needed I come home and find out my package of G2 caliper paint won't be here until Monday...I HATE UPS!!!! At least I'm working from home Monday and Tuesday so I can still do the job, I would have rather had those days as a cushion in case anything went wrong.

 

You really don't need to take the calipers off to do a good job. There's plenty of room to paint them and you can move them around so you can get the entire caliper. Just be sure to cover all you can so you don't get over spray on anything else cuz it's a pain to get off.
