You'll deffo have to get the handbrake drum off, after that, dunno.
(Use an impact driver on the little screw to make sure you don't b
ugger the head.)
As they jiggle about once loosened off, I'd imagine it can't be too hard!
Took my drum off not long ago, never though to look inside to see what holds the captive bolts in place.

Best of luck!
