Can't see it's any nastier than brake cleaner on the seals and stuff. And any that's left will be very small amounts.
Were the pistons in good enough nick to re-use, or had all the chrome gone?

Isn't WD40 known to rot rubber seals over time? Maybe a bit of silicon spray ontop would revive them?

Where I bought my BMW motorbike USEDto use WD40 on calipers but found that there was a reaction between it and brake fluid. Best to thoroughly wash calipers, pistons and seals in methylated spirit. Seeing as you rinsed using brake fluid there shouldn't be a problem. Also WD40 should not be used on nylon bushes etc. as it makes the nylon swell.

I discovered that about nylon when I used WD40 on some nylon-lined bowden cables on the BM years ago, it made them almost impossible to operate as a result of the swelling of the nylon!
