Rear brake issues

[dnb]

I have a problem with the rear left hand side brakes. Went to move the old girl recently and wouldn't roll down the bottom of driveway as is normal. I checked all 4 wheels and found the one that is the problem.
Tried to turn it by hand but barely moved, but as soon as I loosened wheel nuts off it moved freely.
I've pulled the drum off and found a leaky wheel cylinder.
I've checked for loose or broken fittings and all looks ok.
I will replace the cylinder but will this solve the other problem? I'll have the linings checked before I refit them.
Once again any advice and suggestions greatly appreciated.
Cheers, Darcy

Check for warped drum. You can have a brake shop check it for you and give it a skim while they are at it.
