rebuild the 14 master and stick it on the lt, bet it works !
I bet it will too but I bet it'll have a harshly hard pull on it too.
The problem wasn't the brakes weren't working at all (like it had a leaking master cylinder fluid cup) but that the amount of effort it took to pull the handle exceeded the amount of pull I had. It took a HARD pull to get it to stop.
I'm thinking that a 1/2" master cylinder is the way to go if this an issue on pretty much any ATV.
