If your Polaris ATV's front brake feels spongy or you're leaking fluid, the master cylinder might be toast.
This is a brand new OUMURS replacement, part number MR2125PL01501.
It's the left front master cylinder, so it controls the front brakes.

Fits a bunch of popular Polaris models: Trail Blazer 250/330/400, Trail Boss 325/330 from roughly 2002-2013, plus many Sportsman models (500/600/700/800/850) and Scramblers.

Just one piece, but it's the whole master cylinder.

Comes with a 3-month warranty.

Get your braking power back and ride safe.
