Rear brake, cleaned and greased, brake shoes had plently of meat left so were reused.
Hate to be a problem but.
I do not trust old brake pads. If the bike has been stored for a long time, perhaps with a bit of moisture in the air the adhesive holding the linings on fails. I personally had this happen on the rear brake of my 1974 Roadster and I know of at least two other cases. The linings came off and rotated jamming the rear brake.
So if it were me I would not trust the old linings and either replace or personally I reglue and add a few rivits. All my drum brake bikes have rivits added to the brake shoes.
