Is the bushing that the rear disc brake caliper guide pins slide into replaceable? It looks like it is, and I thought I saw it in a manual once, but I don’t see it listed in the FSM, and I can’t find a part # for it. My calipers sit rather loosely on those pins, and I’ve replaced the pins, so I suspect the bushing in the caliper mounting bracket might be worn. Does anyone have any info on this? I couldn’t find any mention of this in my searches. Calipers bolt to the pins tightly, but pins seem to have more free play inside those bushings than I'm used to. I'm getting a little noise from the rear passenger side when pulling away from a stop, and I've already changed the calipers, pins, rotors, and pads.
