What is the purpose of a Polaris ATV fluid pump?These braking system components on your Polaris Trail Boss 250 link the brakes at the wheel to the lever that engages the system. These parts work by forcing fluid to each caliper when the braking lever or pedal is pushed. Acting as a pump, these parts are able to create the force necessary so the fluid can push the pistons within the caliper outward to make the braking system function properly.
Why are two master cylinders installed on a Polaris ATV?A Polaris Trail Boss 250 has a dual-braking system. This means that the front and rear brakes operate independently. In order for this to happen, it is necessary to have two separate components installed in the Trail Boss 250 braking system. The front component operates a disc braking setup while the rear unit controls a drum setup.
