assuming you didn't grease the slide pins every year, I would say the slide pins are seized..... not the piston.
you need to grease slide pins every year in quebec, or they jam. thats it.... mine are always hard to move after a year.

I grease mine when I change the tires in mid-april or so.
Ideally twice a year, but I don't have time and I need to do it outside, so once a year when the weather is nice....

Can you compress it into the bore? Rust shouldn't be a problem unless it gets inside the boot.

I had similar problem with my 2013 after 1 years and I'm in Quebec too. But it wasnt the piston. I have now 160 000km and never replaced a caliper because of a frozen caliper piston.

Rust on the piston doesnt mean anything if you are still able to easily compress it with a C-clamp or something similar

Like mentionned before, it could the caliper pins that are stuck and need to be re-grease. You have to grease them every year in QC.

My problem was different : The outside brake pad was stuck in the slider and the pad wasnt "freely" moving or floating. So it was stuck agaisn the rotor even if the brake wasnt applied.

So I had to clean out all the slider and the shims, and remove all the rust on the mounting bracket behind the shim. On my left caliper I even had to use a file to have it move freely again. Then grease all this slider every year and it will be good.

This is good advise and a proper fix.
Good job.

I had to grind my pads a bit also, they were too tight in the slot, even when clean. That's bad design. I had to hammer the pads out....

so yeah, clean, make sure pads glide, grind of needed, and grease sliding pins every year.

Probably not the piston, really.

I know guys that swore the calipers were bad and claimed it fixed their problem. That's because the new calipers are CLEAN and pads moved better. Six months later they are telling me the calipers are bad again. I just tell them to go ahead and replace them again.

Don't be like one of those guys.

Easy to find out:

do your slide pins slide
do your pads slide in the grooves
does your piston compress into the caliper easily with a c clamp, or even strong thumb pressure.

you will answer your own question. post results.

my 2017 has jammed slide pins every spring, plus this spring it had jammed pads in grooves... it's a 2017.

Cool that you have it new now.
But I highly doubt that piston was seized.
