You may find that the drum surface has started to break up when the discs are removed, a common problem which will mean new discs/drums.
A new shoe hold down kit may be a good idea they also corrode.
I think the new adjusters and expanders may just take up more adjustment with the cable I'm going to do that with mine shortly as although my shoes and discs on the tourer are only a year old I haven't been able to get the adjustment right.
Wished I'd changed them now.
