Thanks to all it’s good to have a part number , the pads were from peter mulberry and to be honest I couldn’t notice any lack of braking even under hard braking with about 1/3 of the inner pad heavily contaminated ,
I have successfully cleaned pads and shoes in the past but just for peace of mind I will change them .
Then I will have 3 good used spares left over in case I cock up again ( kidding)
