('04 Cavalier, rear brakes) Instead of the since-God-was-a-boy
hold-down spring/pin/cup system, these brakes have a single large,
sort of 'W' shaped spring, spanning the two shoes, and passing over a
half-round retainer at the base. Here's a picture (set of 2):

(As shown is upside-down from what's in the car.)

Question is, how to get the shoes off?

Thanks.
