You'll need to bleed the brake system now. No easy way around it. Sorry.
Guys, bleeding your brakes is not hard, it sounds like you're scaring him. Just go to Autozone and get the little $8 brake bleeder kit. It attaches to your bleeder nipple and you can bleed your brakes yourself. Don't forget to keep an eye on your fluid level in the brake fluid reseviour under your hood. All you need is an 8mm wrench, brake fluid, something to keep the system "closed" so air doesn't enter and 20mins. Piece of cake.
Um...that $8 kit is a piece of crap (I've tried to use it twice). Do it the old fashioned way and get a helper.
I'm going to try this when I install my new caliper. LINK
