Ok so far I have ordered the fowlers piston and seal kit, sbs ceramic pads, hel rear line. And am waiting to hear back from powerhouse as to the size of split seal washer needed it maybe this one. https://www.ebay.co.uk/itm/Yamaha-brake-caliper-split-half-joint-seal-13mm-x-2-2mm-/161104785800?hash=item258297f188&redirect=mobile

O.K then but I don't mean the piston fluid seals or dust seals as I have already stated on two different sites, these are neither & it says two?

They're wrong, I would suggest you exercise caution when looking at independent aftermarket websites/sellers they often get it wrong. The same goes for you offering advice to people on how to do things especially brakes when, by your own admission you've never done it and you clearly don't really know what your doing. [size=78%] [/size]

Well really! done plenty of brake seals thanks so don't need any advise from you.

I've got an idea, gnasher says 1 and bandit says 2 > so I will buy 3 and then that covers all opinions

If there is one then that would explain why you first bleed from the back nipple wouldn't it ?

Great that's what I meant. I have heard back from powerhouse that tell me its 11mm - this one according to them https://www.ebay.co.uk/itm/Yamaha-11mm-brake-caliper-joint-seal-RD350-YVS-F1-F2-N1-N2-XJ600-Diversion-SRX-/151490152619?hash=item23458448ab

Clearly you do as you've got know idea, it all speaks for it's self. Never done it, scour the internet for others advice/Utube etc the offer advice to others which is wrong

It would be funny, but it's not others will believe you and get it wrong or it this case spend money the don't have to. Mine you people like you do put money my way

as owners bring their bikes to me after they've tried following internet forum advice form the likes of you or tried following Utube, only to find out they've been told wrong and it's not as easy as it looks.

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

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

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

Not a fan of his either, not sure what you are referring to about "o rings" brought a sealing washer for rejoining 2 halves from webmoto and pistons and seals from fowlers

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.
