Parking brake assembly

I have been working on my ‘51 for over 9 years now, thanks to plenty of distractions.  I am re-assembling the drive line and am having trouble with the parking brake.  I am using the original backing plate drum and hardware but have new pads.  All parts were cleaned and painted, except for the inside of the drum.  When I try to put the drum on over the pads, it is tight, very tight to the point that I cannot turn the drum.  The adjusters are in as far as they can go and the actuator has no pressure on it.  Is there something I am missing.  Is it acceptable to sand down the shoes a bit or is there an old trick that I need to learn?

Thanks,

Jeremy

Here is a photo of the assembly.  Make sure yours matches.  If it does, then it is possible that the reproduction shoes are made with too much pad.  I would sand them down if needed.

In addition to Tim's suggestion, you might want to check the arc of each individual shoe.

You will need to remove the shoes from the back plate and check each one's fit inside the e--brake drum.

The shoe should make contact with the drum over the full arc of the shoe lining. You can slide the shoe back and forth around the inside of the drum then check the lining for contact marks.

Brake repair shops used to arc shoes to fit. 

Now You will probably just need a sanding block and face mask and do it yourself by sanding the high areas.

I saw several video's by just searching "brake shoe arcing"
