Great that helps a lot - it seems powerhouse are correct as they say 11mm - no mention of thickness (depth of recces ) though ------- still got your calipers out :lol

You need to allow for the crush effect, it's not much but must be allowed for say .05 - 1mm O/D. I've not got one to measure here but it should sit slightly proud no more than a mm.
One of the cheaper ones will work no doubt, it's not like it moves but I've never used anything other than what I've stated. I would go for non split rebuild first, if you can't get the pistons out then go for a split, it's takes only an hour ish to rebuild the thing.

Use the other end of the caliper yaw mate, it's designed for I/D measurements :thumbup

Re: Rear Brake refurb - Disorderlypunk - 31-03-20
ooh god - delboy got mentioned so lets just jump on in
after i split, blasted and painted my rear calipers i definatly replaced mine because after a while they do harden/deform.
the problem is using the correct material and i researched like mad into this because i didnt want to F up and use the wrong stuff like nitrile which is something delboy would prob use if he needed to replace (yeah i have problems with a lot delboys stuff)
the easiest kind of o-ring to get is made of EPDM
thankfully du-pont are chemists and let us into there world by giving a compatability list

Your seal from Webmoto will be fine I'm sure. The use of Orings in place of flat seals isn't really the way to go, yes it will work, for how long I've know idea. An Oring is made to seal around a circumference or and edge, not flat surfaces and won't have the surface contact area of the flat seal. Flat surface area contact will be achieved by crushing the Oring which could cause deformity, which under pressure will leek.
Yes it will work to a point, but I wouldn't recommend it.

More useless internet opinions by people who know nothing or very little :rolleyes
You can either just wipe the seals with a little fluid or brake grease, a little so the surface looks wet.
