Attached. I apologize that my brake photo is from above. I can't get a better photo for a bit.Post a photo of the brakes with the drum removed. In-focus, nicely cropped, and resized as needed.
Is the adjuster at the bottom of the shoes? Or just under the wheel cylinder, above the axle shaft? If the adjuster is at the bottom, someone has changed the rear brakes, perhaps by changing the entire axle. The crappy JB5 rear brakes have the adjuster above the axle shaft.
Aftermarket wheel cylinders may not have the same bleeder-screw thread sizes as the OEM cylinders. As long as they fit the backing plate, have the right thread size and sealing taper for the brake tube, and have the same bore size and length, they should work OK.
But I am suspicious of the brake tubing where it screws into the cylinders. Mis-matched SAE--Metric threads there? Incorrect flare on the tubing to match the wheel cylinder?
I bleed with key on, engine off, so I can watch for the red light. It happens when I push a little more than the system can tolerate during a bleed on the rear. One time, the light came on for a front brake bleed, but it was easy to reset. When the rear is full of air (after running the engine), it's much easier to set the red light.Don't forget that there's two more reasons that the BRAKE light could be illuminated.
I have been the pedal guy for almost all of the bleeds because my local Chevy mechanic explained that the guy at the pedal needs to be careful and slow to keep from setting the red light. As soon as a buddy of mine got in the truck, he was pretty forceful on the pedal, which goes against procedure and what the mechanic said.
While I have to touch the shoes, I figured that a new kit would refresh those old springs and adjusters that may be 25+ or 50 years old (if it's an old axle). Plus, the left one is out of adjustment and it should have adjusted itself.Why? Something else wrong with the rear brakes?
Anyone see any issue with the rear differential? As I said, it could be a 1970s rear end. I've got a photo of the brake line tee, as well.

The ^ brake cylinder from the 1970s? Or aftermarket? That is sucking in air maybe? This is also the side that isn't adjusted perfectly, although we tested it and it is braking ok.
