As always , great info and help Dave. Do you think there is a solution if ,in fact I (we) have over withdrew our piston to far inwards? I used a C clamp , with the old pads still in place when I try to reset the pads for clearance. Hoping , not to push it in to far! I did this on an old 280Z , without using the pads! To far is when piston goes back , an fluid starts running out around the dust cover.....
