Hey All,
I have movement on the backing plate and am trying to figure out how to fix this, it is causing my brake shoes to rub the front of the brake drum. Anyone have a fix, or similar problem?
Thanks

The inside of the backing plate, the part that is on the spindle, it moves slightly forward and back

I have not taken apart my 38 brakes yet but with my 51 Huck setup, this is not possible. The bolts holding everything together are special with shoulders that exactly fit every part including the backing plate. I am goiny to guess that someone has replaced some of the bolts. If this is the front you are talking about, it could mean that your steering arm is loose too.

Does your car have enclosed knee-action front suspension?

Yes it does have the knee action, also I replaced the tie rod recently I dont know if that has something to do with it.
Thanks,

You may have a badly worn brake flange plate bushing.

I made my comments thinking it was a straight axle. Sorry about that.

Okay, we all agree that he backing plate should not be moving around. Especially enough to cause the shoes to contact the drums. Something is screwed up. Big time. Another given. What to do? Well, speculation isn't going to reveal the answer. Take it apart until you discover the culprit. I suspect either wrong (smaller shank) bolts or elongated holes (for the bolts). You may need to find new backing plates and new bolts of the right size. Git 'er done. Charlie

Easy - just replace the large hat type brass bushing the is pressed into the center of the backing plate.See shop manual for proper way to lubricate the bushing. When the bushing is loose the backing plate will also rattle when going over bumps.

Davis38, did you find the cause of your loose flange/backing plate?

I have not yet, just before I went to look at it my steering went out. I took apart the box and noticed my worm gear was really badly worn. Now that has been sent out in hopes of a rebuild. I will let you know of what I find out about the backing plate as soon as the steering comes back.
Thanks,
