Where to source 26mm Shimano Piston Seals?

[Fatmat]

Hello, not very Retro, sorry... but!...does anyone know where to source quality standard shimano piston seals (26mm) other than Chinese ebay sellers, can't seem to find any anywhere! Thanks

What's the brake model no?

I have a few that are letting in air: M447 /M8000 / M596, I've always cleaned them and they've come back to life but over the last year it's not been working & they've started to pile up. All the seals look the same so assumed they're all the same size, is that not the case?

Shimano treat many calipers as a unit -

although I thought spares were available for the higher end ones, but maybe not?

Yes, it does seem that way, they're relatively cheap so makes sense to just replace the whole thing, I've some coming from China to test but they're taking forever & getting restless! Thanks anyway

They've never sold seal kits for any of their calipers unfortunately.
