Just search for "brake lever piston shimano" on ebay.co.uk / ebay.com depending on where you are and in Advanced Filters(right next to search button, if you're using desktop site)> Item Location> check "only UK" / "only US" and you'll find ones with normal shipping time.
Please share your experience with us if you'll buy any. If any trouble I could give you item links themselves.

I know, but it's usually the cheapest from China. 😅
I just bought new levers to replace the leaky ones.

I'm curious whether anyone has used one of the Ali replacement pistons and/or seals yet.
My second pair of BL-M6100 levers in 2 years started leaking recently and I'm not very keen on getting a new pair of levers every year..

These brakes have a two year warranty. WTF?

I have replaced the pistons using the "shoutai" titanium pistons a while back and they still leaked. I know some guys that have had success with the "risk" brand replacement pistons/seals.

I recently gave the bore of the master cylinder of one lever a polish and replaced the diaphragm as well as the diaphragm was leaking and the diaphragm is now not leaking. But the piston is still leaking. They are a few years older xt deore set so YMMV.

Hello. I have recently bought the risk brand and was wondering if they do fit in Deore. I have an m6100. They do but the problem for me lies in filling up the oil. After injecting enough oil from bleed port to the lever with oil coming out of the funnel, releasing some air throught the port, then pressing the lever to try to get out some more air while quickly turning the bleed screw on and off in quick succession (as stated by the shimano manual) the lever does not spring back fully and air gets trapped inside. I have repeated thw process many times with same disappointing result. Does anyone have any suggestions or maybe those Risk seals really not meant for Deores?
