It's the front. I had to remove both calipers to rebuild the front end. I changed all the bushing and seals, cleaned up the frame and sand blasted the arms and panhard rod. All because I needed to get a new pig for the front... How great is that! You have it apart and figure hey I may as well do this and this and this... never ends.
I love it.
regarding the bleed value. It literally looks like someone chewed it off. I'm going to have to easy-out it. that's why I need a replacement.
I did get the pad off, with a little persuasion for a hammer and screw driver.
