bit of a thump noise when braking

Something else to check - have the slave/handbrake cam worn the back plate?  The slave cylinder is meant to slide in the grove, and the handbrake cam slide with it but 40 years of wear on my Spitfire had left a few groves and the assembly would momentarily get caught in the wear marks, then suddenly release and thump the shoes against the drum.

when its warmer and you have a lust for removing brake drums make sure the trailing shoe is not fitted upside down

the spare square hole for the handbrake lever must be at the bottom of the rearmost shoe not at the top like the front, leading shoe

its a good one for knock ,bangs and poor adjustments
