Sram Force 1 Hydro Squeeky Lever...

I have Sram force 1 Hydraulic brakes, when I first got then as you press the levers fast or slow, hard or gentle they always squeak and feels like minor resistance, I was told this was normal and should disappear soon, I've used the bike only around 5 times in about a year and now its sooo much worse it brakes perfect, and braking performance has not dropped but the squeel of the lever has gotten worse.

I before I do a full bleed of the brakes, I was hoping to find some feed back of anyone who has had simular issues
