Yes, I agree, i rarely pull the disc. and turn. I have changed a lot of pads, and i use the C clamp because the caliper "floats" or moves; however, on the LS looks like there are four pistons with a fixed caliper. Seems to me that you will have to wedge some thing between the rotor and pads on one side and push the two pistons in, put the pads in and then do the other side of the rotor.
