Ok so someone said that it could possibly be water in my line because it only does it when hot. If I leave it out in the sun the front brake locks up. When I bring it into my house with a/c and the reservoir cools of it slowly starts to break loose. I re bled it time after time with new fluid and it's still doing it. Also not to mention the bike is a 2014 with very little hours on it. Someone please help!!!

You try a new brake line? You need to start weeding out what it could be. So try the line, then master cyclinder then caliper.

I don't have any info on your exact problem but that's how I got rid of a spongy brake on a CRF.

Make sure you are not over-filling the reservoir. When it gets hot and pressure builds, the fluid is going to move to where it can, possibly causing your brake to engage without the lever. Be able to see a decent amount of air in the sight glass. When you have it apart, make sure the pads are sliding freely in the squeeze-unsqueeze direction of the rotor. I've not seen a bad line cause too much pressure, but Joe is right as far as weeding things out. A brake setup is fairly simple, there are only so many variables it could be. If you have access to another brake setup, years are fairly interchangable among Nissin if thats what is, except for the caliper which would be my last look, start interchaning with the rest and see if you can isolate whats bad on yours.

Add a bit of free play in the adjustment at the lever, and see if that helps.
