When bleeding the rear brakes on a Polaris four wheeler there are two bleed screws on the right rear wheel What is the purpose of the two bleed screws?

The two bleed screws on the right rear wheel of a Polaris four-wheeler are designed to ensure complete removal of air from the brake lines during the bleeding process. One screw typically allows for bleeding from the caliper, while the other may provide access to a secondary chamber or line, ensuring that all air pockets are eliminated for optimal brake performance. This dual setup helps maintain effective braking and enhances the safety and reliability of the vehicle.
