I changed my rear brakes on my 1997 K1500 suburban and the right side keeps adjusting up after driving around town . It won't take long for them to run up . Before I take off the drum , did I put the star wheel on back wards ? It's the same one that came off . The left side works fine . Any help ? Thanks

Post a picture. What comes to mind is:

1. It's flipped
2. You missed the thin washer
3. You didn't clean it

Aside:

Hopefully you put a little white grase on the pressure points on the shoes.
