I heard this as well before from the saturnfans forum, I've been unable so far to find the post again talking about it, I remember it being something about the fork needing to be adjusted in the replacement kits to account for the different size pads in the drum or something.

 

I saw that they are an atrocity. Actually, probably a part of Saturn's anti-diy bias. It is not user friendly. I had things fall apart briefly after doing a brake job. I had had something wrong. No big damage was done. The brakes now work well but one wheel squeaks on harder braking. I deduce (theorize) that I may have failed to put grease on the backing plate. This could not squeak but the drag could cause the shoe to cant a little causing the squeak. This is because this is listed as a cause for this malady.
But usual brakes do not even come near the backing plate, being suspended above it by the shoes notched into the pistons and the springs. But with Saturn, the shoes are sliding against the backing plate. I intend to look into it ASAP. I also have a new WC to put in that side, but don't like to immobilize my transportation, even though I have alternative.
Still, I think your case is a worst case scenario. Maybe we should set up our rear brakes with the factory gig and be on the winning side.

 

Actually all brake shoes are meant to contact the backing plate on the three raised area for each shoe. Been that wat forever.
