Hi all,

I've just put on a new drum, brakes, and hardware (minus the lower spring). I have adjusted the brakes until the wheel will spin with moderate force a little over one rotation. If I stop the vehicle, then release the brakes the car will move forward under its own power. I hear no noises, but I can smell the brake and the hub gets hot enough that if I spit on it it sizzles off immediately (which is different than the other side).

I had just pulled the axle. I had attempted and failed to pull the hub with a puller. As far as I could tell nothing had moved at all. When I reinstalled the axle I greased the original bearing and reinstalled everything in the order I had removed it, minus installing a new gasket between the axle housing and the shims. The gasket might have been marginally thicker than the old one.

Any suggestions on this? Keep backing off the brake?

Paul

If you have *working* self-adjusters you could keep backing of the adjuster until it is not dragging and let the adjusters try to do the adjusting. You may have to clean and lightly grease the adjusters.

Alright, we will try this on my friend's new project after it returns from the shop for the installation of the new tires from 4Wheelonline plus the alignment.

1. Year, model, 9" or 10" brakes?
2. Why minus the lower spring?
3. Adjust the starwheel, stomp the brakes hard to recentre the shoes, adjust the starwheel, stomp the brakes to recentre the shoes, etc until you get them where they're supposed to be.

Star wheel threads I believe are well served with the threads cleaned and "Never Seize" on the threads VS some greases.

How old are your soft lines? Old ones can swell up over time and resist the flow of brake fluid.
When you step on the brakes, the pressurized fluid goes to the slave cylinders, but doesn't easily return back to the master cylinder due to the restriction or complete blockage.

I would clean off all that never seize and use some dedicated brake lubricant that will stand up to the high temps and not harden. JMHO.

Never seize is what I always use. I've taken parts apart after years and while it may have slightly dried,it is still there doing its job. Regular greases all dry out as well.

What Rick said.
Also that missing lower spring might have something to do with the dragging problems. Also did you make sure to put the primary shoe ( shorter friction lining) towards the front on both sides?
Or are both "big shoes" on one side and "short shoes" on the other?
Or "short shoe on the left" on both sides? (Meaning that the shoes would be backwards on one side) over the years of turning wrenches for a living I've seen it all when it comes to drum brakes.

I used to use never seize, but now I use disc brake caliper grease. I like it better.
