Okay guys I got a new one for you. I recently posted a topic about why my disk brake was really hot and pulling hard when I was riding. Well it was the disk brake. I have removed the brake pads, they are a little rough looking, but they should work still. But the true question is on how to free them up. I was told to spray DW-40 or a penetrating oil on the pistons. Also when I squeeze the brake lever, the pistons do not return, they stop at there farthest point, therefore if I keep squeezing the brake lever it will keep going out. Any ideas? If I bleed the caliper, will it relieve pressure?
