Shimano XT 203mm disk brakes.

Rear has gone spongy and lever is pulling to the bars and not doing much. Suggestions please? Thanks

Have you bled them ?

Have you bled them ?

Not yet - ordered a bleed kit and Shimano Mineral oil as I only have DOT 4 and 5.1 (god only knows what happened to that bottle of Citroen LHM from the 90s!! that I was sure I had stashed somewhere) but it's going to be a while coming. Didn't want to risk a bleed without replacement oil.

Wondering why they would need bleeding after only 500 miles and 10 months?

I store the bike vertically against a wall using a wall hook

It's a "feature" of Shimano.
Luckily they made their calipers and levers disposable items

Thanks Gary very helpful. What would you suggest I replaced them with. Especially as I've previously had them and been very happy with them.

Think I've found the cause...

But it says my 12mb MP4 is invalid. Darn even the technology is beating me today. Time for a beer and a book...

upload to youtube ??

Though the second option is more relaxing and rewarding ...

If they're under 2 years old your point of purchase can warranty the faulty end for you.
it's still up to you to fit or have someone else fit it for you though.

The fault was a loose hose connector to the caliper. So hoping some oil and a bleed will sort it

Citroen LHM and just bleeding from the reservoir seems to have worked.
Will bleed and refill with Shimano when and if the full Shimano kit ever arrives....
