I have a Karavan trailer and recently had 10" drum brake cylinders fail ... one side sized the other leaking fluid.
Pretty surprised by this on a trailer only 2 years old.
Stripped, found significant salt water corrosion ... honed out bores, reassembled and working for now.
I have ordered spares :

The cylinders (have seen term uniserve ) operate a rod on one side only.
The issue I found (root cause) is that the rubber boot that goes over the end of cylinder through which the rod protrudes had splits, allowing salt water ingress.
Does anybody know if I can get spare boots ... happy to buy a pack of 10 or similar.
I would then change the boots with annual hub/brakes service.
These boots must be cheap ... and as I live in UK, would happily change them annually to avoid cylinder failure again, expensive to import the complete cylinder kits.
If it helps ... part No. on rubber boot is XH 3801 - 3502045
On the cylinders there is the initials AGP.
Any help appreciated.
