The caliper should not  come off the car unless you are relubing the  
guide pins.  Make sure you properly torque the carrier bolts.  I  
think they *might* be use-once items, I don't recall.  They also  
might be loctited.  Also don't recall.

Get the calipers back on the car, install the pad closest to you,  
squeeze the piston all the way back into the caliper (C-clamps are  
slow but work; LARGE channel-lock pliers are better) and slip the  
rotor on at an angle onto the hub, with the back end out.  You do  
this bringing the rotor from the front end of the car to the back,  
ie- over the installed pad.  Almost like putting a shoe on your  
foot.  Then, pop the "inboard" pad in, re-install the wire clip, and  
you're done.

Some pads require some filing to clear the rotor as they're too  
thick; Porterfield's pads were like this.
