FAQ

How do I know my master cylinder needs a rebuild?

A soft or sinking pedal or lever, fluid leaking at the master cylinder, or fluid that keeps dropping in the reservoir are the usual signs.

What comes in the kit?

All Balls lists one boot, two master cylinder cup seals, two master cylinder piston sets, one O-ring, one snap ring and four washers.

Which models does it fit?

All Balls lists Arctic Cat Prowler 1000 (2009-2017); Arctic Cat Prowler 500 HDX (2014-2017); Arctic Cat Prowler 550 (2009-2015); Arctic Cat Prowler 650 (2006-2009); Arctic Cat Prowler 700 (2008-2017); Arctic Cat Prowler HDX 700 (2011-2017); Arctic Cat Prowler HDX 700 Crew (2017); Arctic Cat Wildcat (2012-2016, 2018-2019); and more, see the full fitment list below.

Is installation difficult?

The master cylinder is removed and disassembled so the piston, cup seals and boot can be replaced. Reassemble, refill with the correct fluid and bleed the system. All Balls does not publish an install sheet for this part.

Should I rebuild or replace the master cylinder?

If the bore is clean and unscored, a rebuild kit restores it for far less than a new master cylinder. A pitted bore needs a replacement unit.
