Good To Know

Q: Will this brake master cylinder fit my Sportsman? A: It is intended for the front left position on Polaris Sportsman 400, 450, 500, 600, 700, and 800 models. Compare your existing master cylinder and mounting before ordering, since variation can occur by year and serial number.

Q: Does installing this require bleeding the brakes? A: Yes, any hydraulic master cylinder replacement requires bleeding the front brake circuit to remove air. Use the correct brake fluid and check for leaks at the fittings after installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
