I just installed a new set of Wagner front brake shoes on my 68 Charger R/T. The shoes are the 11"x3" I first ran the adjusters all the way in before attempting to reinstall the drums. I was able to get the passenger drum on with a lot of effort, but I could not turn the drum at all once it was on. The driver would only go on about half way over the shoes. I decided to not try and force it any more, so I removed it at that point. The drums are very clean. There is no lip on the front edge. One thing that I noticed was the linings on the secondary shoes are about .050" thicker at mid shoe than they are near the top of the shoe. The lining then gets a little thinner as you go down the shoe. The linings thickness of the primary shoes do not vary through out their surface and are about .050" thinner than the secondary ones. I would think the lining thickness would be the same on all of the shoes and not vary. Has anyone else seen this or ran into this problem?

Perhaps the brake cylinders were not completely bottomed out (compressed) I usually take off the MC cap and force the fluid back up into the system with pressure on the shoes, and relaxing the adjuster. Then you mount the drum, pump the brake once and dial the adjuster out until you cant spin the tire one complete revolution, then pump it once more and adjust again. Yes, brake shoes are a bear when the darn drum doesnt wanna go back on.

That is done to compensate for a drum that has been turned, typically back when it wasn't recognized as a health threat we would grind brake shoes so the radius of the shoe face matched the brake drum...If you don't do this & install the new shoes only a small portion of the lining will touch...Now they arc the shoes to near the max drum size & let them wear in...Grinding shoes became illegal many years ago & the equipment virtually doesn't exsist anymore outside of a manufacturing facility...
If your brake shoes are both touching the anchor pin at the top & fully seated to the adjuster at the bottom the shoes could be made wrong...

Armature grinder...Or Growler? I've used those too...  Though both technologies were on their way out when I started working on cars...I just located a Distributor machine I'm trying to acquire..  Reread your post, armature lathe.. After that you need to undercut the mica insulators...

Hah! Haven't done a brake job in 40 years, and was wondering what they do nowadays, since making asbestos dust became politically incorrect. One would think that the newer friction materials wouldn't be a hazard to arc grind to fit the drums...

Biggest problem Ive seen why drums wont go on is there is a lip on the drum from rust and crud.Same when they wont come off.That and Ive seen the park cable hang and move the E bar a bit.It dosent take much.Have you turned the drums?Ive had some brakes even with new shoes and new drums that are just snug.Then when you use them once oe twice they seat.Rocky
