I have a 2013 Marine Master trailer with a A-60 tongue.
Recently noticed the brakes are not working and the master cylinder was empty. After filling and bleeding, I noticed a leak at the tongue. I have disassembled the tongue and thought I would find a loose fitting or an obvious leak, but I dont see anything obvious. I am starting to think it is an internal leak in the master cylinder itself.
Given 6 years of use and a couple of 2000 mile trips, is it better to replace just the master cylinder or the whole unit?
thanks
