.. meaning, when you take the old pads out, is there a slot to screw the piston back in or do you have to use a clamp?

I did a search but didnt come up with anything.

Thanks for your help.

To answer your question, the piston surface is flat but is hollow. So what you would do is just use one of your old pad backings and sandwich it in between the piston and the caliper and push it back in.

Exactly. I used the back of the pad and pushed the piston in. THe piston is the circular part and if you use your thumbs, its gonna hurt

I'm not really sure what you mean. I've done brakes before, but this isnt ringing a bell. Maybe I'll figure it out when I pull everything apart.

The piston on the GS is a cylinder shape but is hollow like a tube, so all you have to do is use a old pad and force the piston back in. I know the type of brakes like you had stated where there is a nub indented into the piston where you have to have a special brake tool to screw it back in instead of pushing it back in.
