Rear Drivers Caliper sticking. Replace both?

[Alpine 318is]

My rear drivers caliper is sticking on my X3 so I'm gonna replace that as well as doing the rear brake pads and sensor. Is there any reason to replace the rear passenger caliper as well.

Thanks

Old school would be a yes, modern times it should be inspected while the other is replaced, but if it's good, then it's good. I don't hear about calipers locking up or leaking like they used to, but ymmv.

I went with both. I didn't want to mess around with 2 different age calipers.

Couldn't you have just done a refresh kit? Was the caliper slider pin sticking or the actual piston?? If piston, then yes I'd probably just replace vs. messing with it.

Probably, but for me and considering this is my main mode of transportation it was easier to just get the rebuilt rear calipers, some new brake pads and call it a day. They are done and installed.
