I had the same thing happen after only about 3 years. I took the whole
system apart. The wheel and master cylinders were full of crap. Cleaned
things up and the brakes were fine afterward. I started putting a piece of
electrical tape over the vent hole and kept a 5 gal bucket over the actuator
when not in use. I think that helped.

When checking the brake fluid level on my boat trailer the fluid appeared
to me to be very dark and a little nasty looking. Consequently I decided
to have the seasonal maintenance done a few weeks earlier than usual and
included having the brakes system flushed and refilled with fluid as part
of the job.

The point of this, finally, is that you may find it useful to have a look
at the brake fluid in your trailer before your next maintenance interval.

Happily, as we fish year round in the Mobile area witerizing is not
something I have done anymore.
