Yep for sure. There was a lot of crud. I removed the old seals and cleaned them, just in case new seals were fubar. Then, scraped out as much crud as possible - there was a lot! Used some brake fluid as lubricant on the seals, as I didn’t have any grease to hand. Had a little pot from the DR’s MC rebuild kit but it went walkies.
Pouring with rain on the way to my sister’s, so I couldn’t really risk practicing full braking. They stop the wheel and feel ‘ok’. But currently they don’t feel right.
Not spongey, just not right.
There’s a chance the discs need scrubbing, the brakes need rebleeding, a seal got nicked, etc etc.
I’ll ride them for a couple miles in town traffic to be sure - I spent the past week riding the DR and mtb, so there’s a chance it’s me.
Probably rebleed them today or tomorrow regardless, just to be on the safe side.

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.
