"Chirp" from passenger side, rear

[goldxc70]

Heard this "chirping" sound from rear, passenger side. Observed that it was road speed related so drive train or hub related. Removed (with some difficulty) rotor/drum and immediately saw this.



Not one but two broken springs (bottom hold-down and small springs) caught up on top hold-down! Fortunately, I had replacements for both so was able to quickly fix.
