[Closed] How does this shimano bleed kit work?

no idea, looks to me like a kit for avid brakes...

to 'do' shimano brakes, you need:

one 50ml syringe
one 10ml syringe
some clear hose - about 150mm (i can't remember what size/diameter)
one 7mm spanner - for the nipple (or is it 8?)
a nice sharp phillips screwdriver - to remove the top cap

the big syringe + hose is to push oil in through the calliper, the little syringe to hoover it from the reservoir at the lever.

That's an avid kit so it won't work.

Just go and get a syringe from a vet/chemist for 25p and a wee bit of hose then attach it to the bleed nipple and push the fluid up from the caliper.
