This MotoSport guide walks you step-by-step through safely flushing and replacing the brake fluid on a 2009 Can-Am Outlander 800R XT. Follow these procedures to restore firm pedal/lever feel, remove moisture from the system, and protect the hydraulic components. Work in a well-ventilated area and take all safety precautions listed below.

Safety & prep

  • Wear eye protection & gloves. Brake fluid is corrosive to paint and skin.
  • Use DOT4 brake fluid unless your owner’s manual specifies otherwise. Only use fresh, sealed fluid.
  • Secure the machine on a level surface with the parking brake engaged and engine off. Chock wheels.
  • Have clean rags, a catch container, clear plastic tubing to fit the bleed nipple, a wrench that fits the bleed nipples, a turkey-baster or fluid transfer syringe (optional), and replacement fluid ready.
  • Protect painted surfaces with cardboard or shop towels to catch spills. Dispose of used fluid legally.

Identify components

  • Locate the master cylinder reservoir(s) and verify fluid level and condition. On the Outlander 800R XT the reservoir(s) are easily accessibletop up only with new fluid as needed.
  • Find each caliper bleed nipple and note hose routing so it won’t trap air during bleeding.

Bleeding strategy

Use the standard furthest-to-closest method relative to the master cylinder: the most distant caliper first, then the next furthest, finishing with the caliper closest to the master cylinder. Typical sequence on many Outlander layouts is rear caliper first, then right front, then left front, but confirm by tracing hydraulic lines from the reservoir to each caliper on your ATV.

Method A — Manual pump (single-person, reliable)

  1. Top up the reservoir with fresh DOT4 fluid. Leave the cap off but cover loosely with clean plastic to avoid contamination.
  2. Place a clear hose over the bleed nipple and submerge the other end in the catch container partially filled with fresh fluid to prevent air being sucked back in.
  3. Have a helper slowly pump the brake lever or pedal to build pressure, then hold it in the applied position.
  4. Open the bleed nipple with the correct wrench about a quarter-turn to allow fluid and air to flow into the hose. Close the nipple before the helper releases the lever. Repeat pumping, holding, opening, closing until only clear fluid with no bubbles flows.
  5. Top up the reservoir frequently during the process so it never runs low. Work through each caliper in the ordered sequence.
  6. After final caliper is bled, pump the brake lever/pedal until it feels firm, then recheck reservoir level and tighten the cap.

Method B — Vacuum/hand pump bleeder (one-person)

  1. Fit the vacuum pump to the bleed nipple with the clear hose and start an external catch container.
  2. Open the bleed nipple and operate the pump until fluid runs clear and bubble-free. Close the nipple, then move to the next caliper.
  3. Monitor the reservoir and top up frequently to avoid drawing air into the master cylinder.

Method C — Pressure bleeder (fastest, for frequent service)

Attach a pressure bleeder to the master cylinder reservoir, pressurize per the bleeder manufacturer instructions, then open each bleed nipple in sequence until clear fluid appears. This method is fast & efficient for full system flushes but use care not to overpressurize.

Complete system flush (recommended)

  • To fully replace old fluid, continue bleeding until the fluid from each caliper matches fresh fluid in color and clarity. That typically requires repeated cycles of topping and bleeding.
  • After bleeding all calipers, double-check pedal/lever firmness, check for leaks at banjo bolts and bleed nipples, and ensure the reservoir level is correct.

Torque & final checks

  • Tighten bleed nipples and banjo bolts to factory torque if available; snug and then verify no weeping. If you don’t have torque specs, tighten securely but avoid over-torquing soft components.
  • Cycle the brakes multiple times at low speed in a safe area to confirm proper operation before normal riding.

Model-specific notes for the 2009 Can-Am Outlander 800R XT

  • The Outlander 800R XT uses robust hydraulic calipers and braided or OEM-reinforced hoses on many XT packages. Inspect for chafing where hoses route near the frame and suspension arms.
  • Pay attention to the parking-brake mechanism and rear brake linkage; ensure free play is correct after bleeding and that cables/latches are lubricated and not rusted.
  • If your machine has aftermarket accessories (winch wiring, racks), ensure nothing pulls on brake lines or the reservoir. Re-routing harnesses can change bleed order if lines are modified.
  • Rubber components on older machines can deteriorate. Check piston boots, bleed screw condition, and hose softening. Replace worn hoses or calipers before re-bleeding to avoid trapped air or leaks.
  • Store DOT4 fluid tightly sealed and replace reservoir cap immediately after service to limit moisture absorption. Brake fluid is hygroscopic and degrades hydraulic components over time.

Troubleshooting

  • Spongy lever/pedal after bleeding: recheck for air, repeat bleeding sequence, inspect for leaks.
  • Persistent soft feel despite no visible leaks: inspect master cylinder internal seals, caliper pistons, and ABS/valve components if equipped.
  • If bleeding yields no fluid from a caliper, check for blocked lines, seized caliper pistons, or closed valves in the line.

Regular brake fluid replacement extends component life and maintains safe braking performance. If you encounter stubborn issues or suspect internal master cylinder or ABS valve problems, consult a certified technician specializing in ATV systems.
