I'm trying to change the front brake pads on my 1986 Saab 900, and I'm running into problems with the calipers. I've tried pushing the pads apart while still in there to reset the spacing, and have managed to get the yoke to come out a little more than needed for the old pad. However, it's still not enough to fit the new pad in. Then, whenever I reset the piston back flush, it pulls the yoke back so that not even the old pad will fit in. Does anyone have any ideas how to get more play in the yoke? The manual that I have doesn't give much insight, but my guess is that the indirect piston on the engine side of the assembly actuates the yoke, and it feels like it is stuck.
