I have a question about the rear caliper piston on a 2004. The pads I bought had a wear indicator which pretty much made it necessary to install it inboard or it would interfere with the caliper bracket if installed outboard. This pad also had a little pin cast into it that looked like it would catch one of the cutouts in the face of the caliper piston. The other new pad did not have a pin or a wear indicator.
My question is about the rotating/self adjustment action of the rear piston. Does the pin grab/lock the piston and that is what makes it screw out during use, facilitating the self adjustment process?
Thanks for the help.
