Hello,

Look on the back bottom of the drum backing plate there should be either an oval rubber plug or 2 indented oval knock outs.

If the is a rubber plug remove it using a flashlight look inside for the adjusting wheel. Using a brake adjusting tool you will incert it so that you spin the wheel downward. Make sure before adjusting you have the vehicle wheels up off the ground. And only adjust a few clicks at a time. Spin wheel when wheel spins about one and a half times then brakes should be adjusted good.

If it has the knock outs you will need to remove the drum to locate the position of the adjusting wheel and knock out the oval behind it. then do the above.

Here is a diagram....
