After a few days of wet weather & very high humidity I got in my Gen 2, and one of the back brakes 'held' for a second before breaking-free as I backed-up. The emergency brake had NOT been set. The new shoes, drums & hardware have only a few thousand kms. I did a 'roll test' on a slight slope: car rolled easily. I tried a few 'panic stops' on sand & gravel: ABS performed flawlessly, no tire locked & skidded. Once out on the road, I stopped a few times to see if either of the rear brake drums were heating-up from a 'dragging' shoe: both were cool. Q: Before I jack up the back and remove the tires & drums to have a look-see, has anyone experienced something similar? If so, what was the cause and/or outcome? Thanks!
