Brake problem

[dwcsr]

I have a 72 c10 shop truck that the rear brake on the left side keep self adjusting to the point that the wheel won't turn. I have replaced everything. Drums, hardware, shoes and wheel cylinders. Also replaced the brake cables. It had the same problem prior to replacing every thing. I checked the run out on the axle its not bent. The hardware is on correctly as per the service manual. I even openned the bleeder to see if it was still under pressure. It was not. Adjusters are new and on the correct sides.

Any ideas? Is there a conversion back to manual adjustment?
