Hi Max,
Sometimes when cars sit,as what might have been the case with the "parts
Imperial" that you got the drums from,the braking surface rusts in spots
where the shoes are not touching...making the braking surface have an uneven
porosity/grabbing ability.
If it were a disc-braked car that sat long enough for the rotor to rust,the
rotor would rust where the pads weren't..and the rotor would be in very good
condition where the pads were. Even if you sand-down or drive the car to get
the rust off,the surface will be pitted where the rust was...and "as good as
it was when first parked" where the pads were.
I'd check for a consistent braking surface on those drums...as well as
heed the sugg's that Phil,Allan and D^2 mentioned.
Note: In the case of my '75 Imp,when I used to store it outside for the
winter,I'd put it up on blocks with the suspension hanging..and make sure I
rotated the wheels an 1/8th of a turn or so every month so as to get even
rusting on all 4 of the rotors. Is THAT being a bug..or what?!

'75 Imp 4dr <--stops on a dime...and gives you .09 cents change.
'79 440 powered 35 ft RV <--gets rolled ahead a little each month.
