I can't really complain, I got four years out of the brake, but it seems obscenely wasteful to chuck a perfectly good calliper in the bin for want of a rubber seal.
Madison's website holds no clues, anyone have any leads?
I think the seals are the same as in the cheaper callipers but not sure - so you could buy a cheap shimano caliper strip it and use the seals to rebuild your XT one - double check the diameter of the pistons first tho
Most shimano seals cannot be bought as spares
AS TJ says not available. I resented binning a perfectly good XT M765 calliper just because of a weepy seal. So it went in the spares box, just in case.....
Yeah, thought as much. Pretty poor show to be honest, regardless of the original life of the seal. 🙁
Can't justify buying new callipers for seals, I only want to sell them anyway! The rear is still good, might get a little money for that...
595 calipers use the same seals and can be split for easy removal of the seals. They're quite cheap to buy too.
Getting the seals out of the monoblock without a seal pick is a bit difficult, and geting the new ones in is a major ballache.
I've converted a set to run on Hope levers with dot fluid and the seal change was a nightmare. But all the parts cost me nothing, so it was worth it.
And they're on my daughter's bke now, after testing them on my HT last season.
That's how much I trust them.
was thinking this the other day after the second attempt at bleeding my brand new shimano xt (from ribble) still spongy with poor lever feel yet no air in system upon bleeding, hope for me next time.
nb..my other shimanos on my 2nd bike have been flawless for years..

Interesting, what did you use for the caliper seals then?
I think they are lip seals rather than o-iongs yes?
They were 525 calipers and hope mini seals fitted perfectly to convert IS calipers to postmount. (to combat non disc frame brake mounting issues)
used the Hope pistons initially, and they leaked but with the original Shimano ones they've been trouble free for 2 years now give or take a month.
AS al says -0 a calliper seal is not an o ring.
