This MotoSport-exclusive guide walks you through safely draining, flushing, and bleeding the brake system on a 2014 Polaris Sportsman Touring 570 (MMY: Polaris;SPORTST570;2014). Instructions are written for the stock hydraulic system on the Sportsman Touring 570 and assume basic mechanical skill. Follow all safety warnings, use manufacturer-spec fluids, and work on a cool machine on level ground.

What you need

  • Clean DOT-rated brake fluid as specified by the master cylinder cap (use DOT4 unless cap/motorcycle manual specifies otherwise). Only use new, unopened fluid; never reuse drained fluid.
  • Clear bleeding hose and collection bottle (to monitor bubbles)
  • Brake bleeder wrench or correct-size open wrench for bleeder nipples
  • Turkey baster or fluid pump for removing fluid from reservoir
  • Rubber gloves, eye protection, rags, and a container for old fluid
  • Floor jack and jack stands or ATV lift (if needed for wheel access)
  • Assistant (for two-person pump method) or vacuum/pressure bleeder for one-person operation
  • Non-permanent marker or labels to mark hose routing and reservoir levels

Model-specific notes for the 2014 Sportsman Touring 570

  • The Touring 570 uses a two-circuit hydraulic brake system with a single master cylinder reservoir; check the reservoir cap for DOT spec. The system is not equipped with factory ABS on most Touring 570 variants – confirm your unit before proceeding.
  • Reservoir location is on the handlebar area beneath the cap with a visible fluid window or level mark. Keep the reservoir cap sealed except while filling to avoid moisture contamination.
  • Brake lines and fittings on this model are routed across the front and rear subframes; inspect hoses for rubbing, cracks, or chafe while you work. Replace any damaged hose with OEM-equivalent parts.
  • If your machine has aftermarket racks or accessories, remove or shift them to access bleed nipples and calipers safely.

Safety first

  • Work with the engine off, key removed, and parking brake disengaged only when necessary for bleeding. For safe wheel rotation and brake lever/pedal operation, stabilize the ATV on jack stands or a lift.
  • Brake fluid damages paint & plastics. Wipe spills immediately and flush affected areas with water. Dispose of old fluid per local regulations.

Preparing the machine

  1. Clean around the master cylinder cap and caliper bleeder nipples to prevent contamination.
  2. Remove the master cylinder cap and diaphragm and top the reservoir to the MAX mark with new brake fluid. Do not overfill. Keep a close eye during bleeding so the reservoir never runs low.
  3. Identify the bleed order. The general rule – start with the caliper farthest from the master cylinder and move to the closest. On most Sportsman Touring 570 setups this is: rear caliper (if independent), then front passenger-side, then front driver-side. Physically confirm which caliper is farthest on your machine then follow that sequence.

Bleeding methods (choose one)

Two-person pump-and-hold method (common & reliable)

  1. Have assistant pump the brake lever/pedal until firm, then hold pressure.
  2. Open the bleeder nipple one-quarter to one-half turn, allow fluid and air to flow into the clear hose and collection bottle, then close the nipple before the assistant releases pressure. Repeat until clear, bubble-free fluid flows and lever/pedal remains firm when held.
  3. Top off the reservoir after each cycle so it never drops below the MIN mark.
  4. Move to the next caliper in the predefined sequence and repeat. Final pass: re-bleed the caliper nearest the master cylinder to ensure any trapped air is removed.

Vacuum or pressure bleeder (one-person preferred)

  1. Attach vacuum pump hose to bleeder nipple or pressurize the master cylinder reservoir as designed for a pressure bleeder.
  2. Open the bleeder and draw fluid until it runs clear and bubble-free. Keep reservoir topped off throughout.
  3. Repeat for each caliper in sequence.

Flushing & replacing all fluid

  1. If performing a full fluid change, remove old fluid from the reservoir first with a turkey baster. Refill with new fluid and begin bleeding farthest caliper.
  2. Continue bleeding each caliper until fluid exiting is clear and new fluid is present at each nipple.
  3. Once all calipers are bled, pump the lever/pedal to build pressure; check feel. If it's spongy, repeat bleeding sequence until solid.

Final checks

  • Wipe and clean all fittings. Torque bleeder nipples snugly by hand plus a small fraction with the correct wrench – do not over-torque and strip the nipple.
  • Fill reservoir to MAX, reinstall diaphragm and cap, and secure. Ensure no leaks at calipers or lines with brake pedal/lever pressure applied.
  • Test ride slowly in a safe area. Confirm firm brake response and no fluid leaks. Re-inspect fluid level after the first ride and top if needed.
  • Record the service date. Replace brake fluid every 12-24 months or sooner if exposed to moisture, heavy use, or frequent wet operation.

Troubleshooting

  • Persistent spongy lever after thorough bleeding: inspect master cylinder seals and caliper piston seal condition; contaminated or damaged components may allow air ingress and require rebuild or replacement.
  • Low pedal but no visible leaks: check flexible hoses for internal collapse, and inspect banjo fittings and caliper sealing surfaces.
  • If the reservoir label specifies a different DOT rating than DOT4, always match the label specification.

Parts & service considerations

  • Use OEM-equivalent caliper seals, bleeder valves, or hoses for best fit and longevity on the Sportsman Touring 570. Replace any corroded bleeder screws rather than attempting to back them out repeatedly.
  • If you're unsure about the master cylinder condition or detect contamination in the system, consider a master cylinder rebuild kit or professional service to restore reliable stopping performance.

Follow these MotoSport-specific steps and safety checks to keep the brakes on your 2014 Polaris Sportsman Touring 570 functioning reliably. If you have performance concerns or discover damaged components during the service, consult a qualified technician or use OEM-spec replacement parts.
