@TS25 I checked and they are SM-RT76-M front says 180. Thanks for all your help. I also ordered Park Tool Piston Press recommended by @Sierratim and you.These are in the BR-M8000 Shimano line-up so they should fit. Expensive though.
As my brake is a different model I can't add practical experience.
Others from Shimano are: G02S, G02A, G03A, G03S, G04S, G04A, G04Ti, J02A, J04C.
And there are others from other brands.
Did you manage to find out which disc rotor model your Vado has been equipped with?
F.e. @Sierratim posted his is a SM-RT76 but other Vado 5 and 6 with Shimano BR-M8000 caliper have a SM-RT86 rotor.
please let me know if anything else I need to be careful when changing the pads.
