you might check the pins/bolts that attach the caliper to it's bracket, if these are dirty/rusty it'll hold the caliper still wearing only the inner pad instead of allowing it to float and use both equally.
You probably could but usually the rust is on the caliper which requires a light honing. If its too deep, then usually a new or rebuilt caliper is required to correctly remedy the problem and is much faster in getting the car back on the road.
well i tried removing the driver side "sliding bushings" and i put anti-seize on them to kinda lube them up. The bottom one is sliding pretty good, but the top one is still really stuck there even after cleaning it, putting more anti-seize etc.
Is there any reason why this would be happening?
