If new brake shoes have been fitted or are rebonded to your old metal backers ensure you send your braking drums away & ask the shop re-bonding the carcases to "radius grind" your new friction linings to suit the drum. this will speed up the bedding in process. even with radius ground shoes several re-adjustments will be required. to achieve a servicable brake several adjustments will be required before your shoes have bedded in. i reccomend when replacing the shoes bed them before re-fitting your track. fit the new shoes & prior to fitting the track select 2nd or 3rd gear & allow the sprockets to turn, apply the brakes on & off several times or until your brake drums become warm to the touch, let them cool then re-adjust the shoe positions as per manual, repeat the process until bugger all re-adjusting is required. do not o/heat the linings at this stage- if the drum is too hot to touch you have let it get too hot. when you have worn the "fur" off the new linings one final re-adjust & refitt the track & away you go........this bedding in process is common to all drum brake systems but most don't have tracks to contend with. it is much eisier to adjust the brakes with the track off so bed the brakes with the track off. I hope this is of assistance.
