Quick question.
I have a new Dorsey trailer w/ surge brakes.
I checked the fluid level today when we got back from the lake and it looks
low.

What kind of fluid should I use to fill it - brake fluid or hydraulic fluid?

My FIL says hydraulic - but I think brake. I dont have the manual and I
cant find it online any where.

Your father in law is right in one respect - brake fluid is a type of
hydraulic fluid. However, you need to use brake fluid and I suspect
that Dorsey recommends DOT-5. DOT-3 isn't recommended for immersion
in water.

As Dorsey is no longer in business, play it safe - use DOT-5.
