5.14 Final Drive/Brake System 9923311 - 2010-2012 PRO-RIDE RUSH/Switchback/RMK Service Manual © 2011 Polaris Sales Inc. BRAKE SYSTEM General Guidelines Keep these points in mind when bleeding hydraulic • The master cylinder reservoirs have limited capacities. It is easy to empty them during the • Apply only light to moderate pressure to the lever or pedal when bleeding the brake system. • Small amounts of air can become trapped in the banjo bolt fittings at the master cylinder(s) and • Always torque banjo bolts and other brake system fittings to specified torque. • Change fluid every 2 years, or when fluid is dark or contamination is suspected. WARNING An unsafe condition exists when air is trapped in the hydraulic brake system. Air in the brake hydraulic system acts like a soft spring and absorbs a large percentage of the pressure developed by the master cylinder. Without this pressure, the braking system cannot develop full braking force to allow for safe, controlled stops. It is extremely important to bleed the brakes properly after any brake system work has been performed or when inspection reveals spongy brakes. A soft, spongy feeling in the brake lever and/or brake pedal could indicate a hazardous condition in the brake system. Do not operate the vehicle until the failure in the brake system is corrected. Keep brake fluid tightly sealed and out of reach of children. Brake fluid can accumulate moisture, reducing it's effectiveness. Contaminated brake discs or brake pads greatly reduce braking performance and increase stopping distance. Do not attempt to clean contaminated pads. Replace them. Clean the brake disc with brake cleaner. This brake system requires ethylene-glycol based fluid as silicone-based or petroleum-based. Do not use brake fluid taken from old, used or unsealed containers. Never reuse brake fluid. CAUTION Pressure bleeding is not recommended. When fluid surges through the fittings, it is possible to cavitate the fluid and create air in the system. In addition, the fluid stored in a pressure bleeder may be contaminated. Al- ways use fresh DOT 4 brake fluid from a sealed con- tainer. |
