Master Cylinder Rebuild + Stahlbus Bleeder Valve

Hi,
Here is a feedback about rebuilding my Sprint ST 1050 master cylinder.
I purchased a Nissin rebuild kit for around 25 euros.
1- bleed to empty the MC
2- remove the MC from the bike (Very easy)
3- remove the lever
4- remove the clip. that's the guess work, moreover without the special plier. To remove the clip, the piston need to be held pushed. With some patience it's not impossible. If I have to do it again, I will purchase the correct clip remover plier.
5-clean the MC, with fresh dot "oil" the new piston.
6-put everything together.


I took advantage of that work to try those Stahlbus bleeding valve.
It's basically a caliper bleeding valve with a built in pressure valve.
It's a bit pricey (25 euro each), but very efficient.
Unscrew 1/2 turn, put your waste tube on.
Press the lever and you don't need to take care of the bleeder.
It makes brakes bleeding so easy.
