alfasud handbrake adjustment self-tightening

[daltonh]

One of the inner handbrake adjustments on our alfasud keeps tightening up. It may be tightening up a bit each time the handbrake is put on and off but I'm not sure. It causes one of the inner brake pads to drag slightly. Has anybody found this before? Solutions? I rebuilt the calipers a few years ago but don't remember anything special about the adjusting bolt. Thanks.
