Since you have an issue, you may a well take a look at the brakes and see if there is anything going on. Be sure your shoes are still good, not worn out. You can clean them up with brake cleaner from a parts store. If necessary you can adjust them with the drum off. Only problem with that is it might be a little difficult to get the drums back on if the adjustment is too close.
Without removing the drum, they can be adjusted from the backside by removing the rubber plug then use a brake spoon to move the adjuster for a tighter clearance.
The correct place to adjust the parking brake is via the adjusting wheel inside each of the two brake drum assemblies, not at where the parking brake cable splits to go to the left/right wheels. Adjust them with the drums in place.

i've had this problem with my latest TJ. had 2 different shops look at it, but nothing is helping. i know the brake shoes are in very good shape, so it's not that they are worn out. both shops said that they adjusted & everything is good, but i get in my driveway (only a slight incline) and it drifts. almost as if nothing is even holding it.
