I have a significant tight spot when adjusting drag in rear wheels of my Tudor. Front wheels OK. Takes both hands to turn past a certain spot, even after backing out the adjusting screw. Could the hub be out of round or something sticking?

Probably not hub out of round but certainly something is "stuck."

The "eccentric" of the rear wheel brake shaft is likely stuck and prevents any "equalization" between shoes. This is a common fault and will prevent "pull back" of at least one shoe by the springs.

The key descriptor here is even with the adjuster backed off, the shoe is still touching the drum. Something is keeping it there.

This slide may help you.

Your drum may be a bit out of round.

Have you been working on the brakes? Or just adjusting?

First, make sure the cam, or eccentric as Joe calls it, is not stuck. It should slide back and forth in the "cam shaft." Consult the Red Book if this is not clear.

But I highly suspect the drum is also out of round. It is most likely a combination of a high spot on the shoes and an out of round drum. Check the shoes first like Bob suggested or glue some course sandpaper to the inside of the drum to sand away any high spots on the shoe linings.

As far as the out of round drum is concerned, the only course of action is to take it somewhere to be turned. If it is the original stamped drum, throw it away and get a new cast iron drum and hub and have that turned.

I don't know where you are located, but there are some good shops in the country to take your drums to. Let us know where you are located and someone on the forum can suggest a good place to work with.
