I don't know Hucks so if these are them this won't apply but from my experience brakes is brakes....
Brakes When I've had this problem I try to loosen the star first then when I know it's frozen start looking to knock the keeper springs off from the backing plate.
The adjustments access is on the back/inboard side.
Grind off the rivet/nail looking heads and use a drift or something to punch the shoes some. Study the pic and read through it.
If you can get any of the others off you'll have something to compare...
