Internal expanding pliers should extract them, you could try sitting a short m6 bolt and nut in the bottom of the piston and undoing the nut until nut and bolt bite and grip the piston, but pliers best.

I hold back the first pistons to move, so that the tighter ones can be pushed the furthest out.

If you get stuck, you can come and use my compressor, once 1 piston is out, the fluid holes need sealing to retain pressure to move the other piston.

Thanks Dave, it'll be the weekend before I get back to finish these now as work is getting in the way and I'm out for a few days. If I get stuck (literally) I'll give you a bell

I bought this last week at the annual fair....you mean this?

Also a brake piston removal plier...

if they are really stuck and are being replaced i have welded a bolt to the inside of piston put in vice to pull out, heat may have to be used too
