rear drum brakes tighten up

[towjoe]

just put rear drum brakes on my 96 K3500 6.5 truck I am building a repo truck out of. drive it to town and back and the rear brakes are adjusted up and dragging bad. right rear wheel worse than left. backed them off drove it about 40 miles and they were dragging again. tore it all back apart and everything looks to be correct. self adjuster moves freely and quite a distance before moving the adjuster like it is suppose to. I have had this problem a few times before with my older k30's of the right rear tightening up. just loosened the brakes up once or twice and never done it again. any idea what causes this? had several people look at brake hardware on all them with no one ever seeing a problem.

Perhaps the shoes are on backwards. There is a front and back shoe. If they're on backwards the brakes don't operate properly. If I remember correctly, the shorter one goes on the back, but I cannot say that with all out certainty.

All I can say is drum brakes are a pain in the balls.

I had the same issue with mine. I replaced all the hardware, wheel cylinders, shoes and it wasnt till I replaced the Ebrake cables that they started working properly.

The short shoe goes to the front !!

yea shoes are on right. easy to remember tall one goes on back like race car tires lol more I drive it the further it goes between tightening up. got almost a 100 miles last time. wonder if just shoes need to seat? you know with these junk parts these days it's hard to say

Adjusters on the wrong sides? One side is reverse thread isn't it?

If all else fails, do like I do, blame it on space aliens.

took it apart one side at a time. if adjusters were reversed it would back them off I would think. Wondering if it has anything to do with that evil thing they put on it known as ABS ?
