After I c-clamped the pistons back as far as possible, I still couldnt wedge the driver side caliper with the new pads on it back on the rotor that easily. (Curiously enough, the passenger side caliper went on easily)

The brake rotor is running hot and grabs and pulsates, I dont think its warped yet, because I've only had it one day on the road and havent hit any puddles.

I'd like to fix this. Is the rotor still good? I'll sand the pad down if necessary.
