OK, so I redid my rear drum brakes. Replaced everything but the drums and backing plate. They worked fine at first and then every once in a while when I put it in reverse the brakes would grab. Then put it in drive and pull forward it would pull the brake off....put it back in reverse and sometimes it would grab again. I just snapped a couple pics so you can see how I put them together. I think I may have assembled the star adjuster incorrect because they are adjusted out a lot further than they were when I assembled it. They are adjusted out so far that both shoes won't touch the cylinder at the same time. Is it adjusting out more every time I put it in reverse? What did I do?
