XT caliper - service or replace

[Gazzab]

My XT m8000 caliper is sticking. It won’t retract. If I push it back in after cleaning etc and then I apply the brakes then the lever goes floppy and the calipers don’t retract. I am not sure if they are fixable or if it’s just easier to buy a new caliper... any thoughts or advice. Thanks.

Multiple options however if the levers floppy or mushy I'd bleed them first

It's not difficult however a bike shop will probably have a fixed price

Have you tried lubing them with silicone? That is what I had to do when mine were sticking.

Sounds like a bleed issue to me, Shimanos are a breeze to bleed and you don't have to piss about with Dot fluid.

That said, it worth following a good procedure, to avoid the dreaded "wandering bite point" and use Genuine Shimano fluid, I've used Halfords / Citroen stuff in the last in a pinch and shortly afterwards the seals have failed.

I have ordered a new caliper and lever. Comes as a pre bled set for £105. Looking on line it looks like my pistons are broken. So to get it fixed / replaced, buy a bleed kit etc seems a ball ache v’s replace it in a few minutes.

Oh I bought it online from Evans (sports direct!!) - terrible comms and terribly slow so far. 5 days and still not dispatched.

Do they definitely have stock?! I've just had a Shimano ultegra caliper warrantied but I can't get a replacement anywhere, whether 105, ultegra or dura-ace!

Apparently it’s on its way :-)
