I melted of my rear brake line last week riding my 2004 400ex. I put on the new brakeline and the rear brakes still aren't working when I press the brake. What do I still need to do?

 

bleed them

 

So I did like you guys said and kept bleeding the line until the nipple at the bottom only had a steady stream(5-6 cycles). I pushed down the brake and the pads still wont move. I took the caliper off of the disk brake to see if the break pads were moving and they aren't. I took the pads out of the caliper and I had to hit the pin with a rubber mallet to get it to move. How do I know if possible my caliper is bad.
