If removing them is a bad idea, why have Yamaha / Sumitomo gone to the bother of making them removable?
I used the tool on my own front calipers last week, the bluespots (silverspots actually) came out fairly easily without damage and are threaded. An O-ring sits in behind the 'caps' to keep anything leaking past them. There was no sealant or bonding agent on the cap threads.
I used a set of replacement bluespot cap O-rings ordered from the same webpage and reassembled both calipers after changing the seals.
Lo and behold - after bungee-ing the front brake lever back to the bars for 48 hours solid they aren't leaking and now work like ...they shouldÂ
Next time I get a chance, I'll remove the blue caps from my original front calipers & post some images up
