The rear left side brakes; so far so good...
Actually rusted and seized.
The right side was REALLY painful to remove. The thread on the drum was probably damaged.
Full of fluid.
The line was also rusted and broke very easily.
Obviously, this cylinder needs to be replaced. It can be rebuild, but the bore has to be nice and sometime they leak again.
Interesting design(Look at the brake line)! :oD
