Ok, so I'm pretty new to this. I took my left side caliper off and when I placed it back on I had no pressure to my front brakes. No stopping at all. Is it because air is in the lines now. Should I bleed them. Help please.

How much fluid is showing in the sight glass? Did you operate the brake lever while the caliper was off the wheel? If you did and the fluid was already low, you might have sucked an air bubble in the lines. Bleed them. IF you have never bled the brakes before, then you might want to do a flush on them while you are in the process. The brake fluid can get moisture in it and start "jelling".
You will most likely have to bleed both sides... no telling where the air went.
