Hyundai Repair: Rear brakes, friction material, star wheel

Question
What about the position of the adjusting star wheel, doe it go towards the front or rear of car?
I have a feeling the brakes are getting looser as I drive and the brakes start squealing when just touching the drum.

I have replaced the rear brake shoes on an 01 Elantra twice and I still have the same problem. I can adjust them up and a few days later the right rear brake starts squealing when you apply the brakes. I may have the adjusting screw backwards but not sure. Both the left and right side have the adjusting star wheel to the front of the vehicle and I am pretty sure that is the way they came off but not positive. Can you help me figure out whats wrong. I don't want to turn the stars around in case they adjust in reverse and lock hub on.

Answer -
Squealing from drum brakes is typically either caused by the shoes rubbing on the backing plate, dust buildup in the drum, or the friction material itself.

Since you've replaced the shoes twice, I expect there's little dust built up.  You might try prying the shoes away from the backing plate and slipping some grease between the shoe metal and the backing plate on the contact points.  There will be six points around the circumference, three on each shoe.  Use a high temp brake grease or anti-seize, and be careful to not get any onto the friction material.  If you use wheel bearing or similar grease, it may melt and get onto the friction material.

If that doesn't solve the issue, it's probably the composition of friction material causing the squeal.  It won't cause any problem with the actual braking, just the annoying squeal.  In that event, I'd recommend purchasing factory shoes for the next time you replace them.

Answer
Sorry, Tom.  I forgot to include that in my answer.  The star wheel goes toward the front of the vehicle, and turning the wheel downward should spread out the shoes.  The arm that adjusts the star wheel should be on the front shoe.  As long as you're sure you didn't switch sides, you're good.  

The general rule of thumb when doing rear brakes is to remove both drums, then only do one side at a time.  That way, if you're not sure how something goes back together, you can go look at the other side.
