I have had a soft brake lever since i did the brakes and today i had the front wheel off for a new tire and noticed now the front brakes are 1000 times better now. I have no idea but it felt like i had air in the lines before. I have never had to remove any fluid in the system and have never had the front line separated from the caliper?

I don't know why but it seams to work great now. I need a caliper rebuild kit just to have in case. But now it feels great and i don't want to mess with it.

Thats very common. I think it frees up some of the build up and helps the pistons move easier. Bet you cleaned the calipers when you had the wheel off.

Any time you have an "air in the line" feel to your brakes, you can gravity bleed them overnight. Loosen (but DO NOT REMOVE) the cap on the master cylinder, and pull the lever as far as you can - slowly, it'll splash - and secure it to the grip, keeping it tight (a zip tie works great). If you want, you can put a shop rag over the master cylinder as a dustcatcher. Leave sit overnight. This will allow any bubbles to "float" to the top of the system.

The shop rag is also a good reminder to resecure the master cylinder lid before riding. Ask me how I know that one.

Mushy lever / tight lever syndrome can happen with stuck pistons. WHENEVER you do any brake pad replacement you need to clean the dust around the pistons BEFORE you push the pistons back in. Once the pad is removed, slowly squeeze the brake lever to see if ALL 6 are pushed out equally. If not, keep cleaning or rebuild the caliper.
