The only service my OZ Mini Van got before heading for MMW in San Diego was the rear brakes...they were locked up after sitting outside for some time.

Pulled the drums, sanded both shoes & drums, hit all with brake clean & reassembled.

Does not take much to lock up the drums.  Even now while driving more regularly, if it sits for a few days, there will be a little dragging of the shoes initially.  I'm thinking the quality of both the S drums and the brake linings (all new in 2014)....

Brakes will stick (pads or shoes) after a week of being parked even outside here in humid Florida. I park a car without touching the brakes and leave the car in first gear with the handbrake off which seems to work.

I sometimes find that after I have washed our car and just driven it a few feet ahead into the garage...and left it for several days, the brakes stick similar to what you described. I always try to drive the car around the block after washing it now...and when I park it, I leave it in neutral with no parking brake on. Use a wheel chock to prevent any movement. This solves the problem for me.

yes, shoes in back, pads in front.

whatever brand... they are in there now. The wheel cylinders will leak again before those shoes (or me) wear out.

again, my only surprise is how quickly this happened: sitting in a barn for a year, or a field for 10 years, yes. Just 2 months in a humid garage - I was surprised. The exhaust fan in the window 5 feet away did not do much good.

Normally, i drive it once a week or two , so this has not come up before.

My turn to guess:
Perhaps with the high humidity, condensation developed inside the drum and was wicked up into where the shoes were touching, then as it warmed up, the moisture couldn't dissipate.

I'm sure Steve would remember what he used, email him or call him.

I've seen that with a brake shoe with some metal in the material.
On cars that sit or in humid environments we tried to use an all organic material shoe, no semi-synthetic. Just by backing the adjuster off and driving the car around to remove the rust on the drum (and shoe) you may have solved your issue.
As long as you're happy with the brake pedal (how it feels to you) you should be golden.

Can't tell you how many cars I've had to drag with the wrecker trying to free up rear brakes after owner parked with the hand brake on.
Wish all of our customers were like you.
Although I had plastic skis to slide cars onto the rollback I found common dish soap worked great to slide onto the aluminum bed, saved jacking up, placing skis under the tires.

Perhaps the shoe material ( not pads, pads are on disc brakes ) had a high metal content(?)

This is FYI  - for want of other stories on the forum....

Mini sat forlorn for 2 months while I recuperated from surgery.
It sat in detached wooden garage with all my other tools and toys,  fan but no AC in humid Virginia. 

Normally, I just push it out to have enough enough room to get in. Would not budge. R rear brake stuck.
The entire brake system was replaced 1.5 yrs ago: pads, wheel cylinder, hoses in back. in front: pads, calipers, rotors, hoses , and master cylinder.

I figured it was just rust. As I could not push the car, or examine or jack it up for want of room in my tight space, so I just started it up and drove out the door, leaving a skid mark with the locked brake.

After removing the tire, I tapped on the drum lightly with a hammer 2 or 3 times,  and the drum could be pulled off easily.  The picture shows the rusty area on the drum where just one pad was stuck, obviously at the ends as these pads and the drum are not the exact same circumference and not fully bedded in yet.   Cleaned it up, and all is well.

I was very surprised that this amount of light damage could lock up the brake so tight. No, the parking brake was not set, but I did have the brakes adjusted to the tiniest faint hint of drag 1.5 yrs ago during installation. Not many miles or wear since then. Maybe that was too close under the wet conditions. So I backed off the adjuster one notch. The rear brakes do not do much braking in normal circumstances anyway.

On second thought, the rest of the drum is not rusted. There must be some type of corrosion process CAUSED BY THE PADS THEMSELVES.  I do not know the brand. I did my first set 15 yrs ago, Steve CTR did  these for me. Not sure what he used.
