There is something that I am just not understanding/processing with the caliper. I cleaned and rebuilt/reassembled the caliper and I am not understanding why the inboard brake pad is so loose... I have not refilled and bled the system yet...It is just on the bike... I am just not processing how that inboard pad applies any pressure on that side of the disc once the system gets filled/bled...The outboard pad gets pushed against the rotor by the caliper piston, but how does the inboard pad function? I am worried that something was assembled wrong in the past, and/or that I am missing something in the schematic/diagram with my assembly (there were no leftover parts after the rebuild)... Any help/advice would be appreciated, as I don't want to fill/bleed the system and then find out it needs to be drained again. THANKS!
 
Assembled correctly, the caliper slides on the bolts or pins that retain it and as the piston is pushed toward the rotor, the caliper slides over so both pads are clamped on the rotor when enough pressure is applied at the front brake lever.

This is a car example but they all work basically the same way.

If I understand you, The whole caliper moves and the bridge/carrier is the stationary part...That makes sense to me now...
