[TR] TR3A Rear Brake Drum

[Scott Suhring]

They are relined original shoes, so they are at full thickness. This was
also suggested, especially on the leading edges, so I am going to give this
a try since it has the least potential damage and can be carefully ground
down. I can then test to be sure I am getting full contact and if not, may
take it to a shop to have it shaped to the drum.  Thanks for the support.

I ran into this when I purchased and installed new shoes, I had to take a
belt sander and take some of the lining off to get my drum back on. How much
lining is on the shoes?

Scott,
I've heard this tightness will settle in, maybe?

Well, I got the new rear cylinder installed in my '59 TR3, but have
encountered a problem that I am scratching my head over. Before I needed to
replace the right rear brake cylinder, my wheel/brake drum turned freely.
Now since I replaced the cylinder, I can barely get the drum on and once on,
you cannot spin the shaft due to the shoes being so tight on the drum. I
have changed nothing else, measured the piston against the old cylinder, and
although the pistons have a different shape, the measurements seem to be the
same. The adjuster wedges are also fully in. Any thoughts as to what could
be causing this problem? I can try installing the old cylinder after
rebuilding it or I could have the drum shaved down a bit.  TIA
