If the brakes aren't springing back enough, perhaps the pistons ar binding up in the cylinder. Go to your friendly part supplier and ask for a rebuild kit (consists of rubber seals and rings n stuff)for both right and left cylinders (may as well do both, if you do one, it will often show up the weakness in the other.).
Pull the Piston cylinders out of the drum, and pull them apart, and inspect the pistons and bore. You might find they are rusted/gummed up a bit. Give them a gentle clean so you dont scratch them up too much, then re assemble, using some "safety circle" brake rebuild fluid (Any auto shop should have it). While your at it, Id also replace the shoes, as they could be thin, also adding to the chance of things binding up. Dont forget to bleed the brakes when you put it all back together.
One thing i havnt mentioned is the hanbrake mechanism, check this is all moving correctly.
If your still not to sure how to do a rebuild, get yourself a manual, or go see a pro.
PS, it could still be a bearings issue, but theres no harm in checking the brakes first, as they should be serviced pretty regularly anyway.
