Well I fitted the rear after getting back from greenlaning, and those seals fit.
Mainly concerned when I looked at the front because there was fluid dripping from the calliper. I was sure that I had wiped it clean, but I may have left some on there. Possibly after all the effort there’s a busted seal in the new kit.
I pumped it over and over and didn’t get a bigger drip, but it wasn’t dry. Will find out this morning if there’s another drip waiting for me hanging from the bottom of the pad.
Update: no big drip, but the space between pad and calliper still has that film of liquid you see when pumping the brake. No time to fully disassemble. Just gonna ride it today for a couple urban errand and see if they fail.

If you've cleaned it thoroughly should stay dry in there. I find that static loading (putting a zip tie around the bar overnight) doesn't do the same as it being ridden, lots of heat and other forces going on = will show up any weaknesses.
You could have nicked a seal, done it before, gutted with myself.
Also find that some calipers begin to rot in that recess where the seal sits, the corrosion takes up valuable space causing the seal to bind on the piston, I always scrape them out with a dental pick until smooth, then use wire tool and a bent screwdriver to smooth them down, then use dot proof grease before putting seals in. Gives them the best chance of not rotting again soon.

Oft that sucks, my last few rebuilds have been fine but once had it on a suzuki with a 4 pot front caliper, one set of pistons were smaller, but the seals and new pistons in the kit were like halfway between the two sizes in the caliper. Was the bikes fault, it had scrappy calipers fitted to it from a different year bike, i didn't know that though!
