the calipers dont slide up like on the fronts. you need to remove both bolts that hold the caliper in. If you put the caliper in a strange position it will cause to caliper to compress because of the ebrake cable.
I would try to compress brake piston more, by twisting it clockwise. And make sure the ebrake is off. wheel should at least spin. It shouldn't be tight.
Pins are the sliding pins for the bracket/arm/caliper that slides back and forth.
I am using the word caliper to describe the entire setup and bracket or arm for the part that glides along the pins.
The whole thing is not even mounted yet so no ebrake cabel in the equation.
I will be trying new sliding pins today from Napa who also ordered me a complete replacement if that doesn't work. I think something is bent (either the sliding pins or the bracket arm itself that slides) because my other rear caliper is stiff, but moves a hell of lot more freely. Thanks again for the input. I will clarify my progress as I figure more out, but anyone with any other suggestions please chime in. For waht it's worth, I contacted the local acura dealer and they said they just replace the whole caliper assembly with a reman one instead of rebuilding it themselves. It looks like I may end up doing that anyways after all this trouble!
Piston is in all the way and lined up properly, but has nothing to do with the way th earm is sliding back and forth because it happens even without the pads installed.
