This step-by-step MotoSport guide walks you through safely flushing and bleeding the brake system on a 2011 Can-Am Outlander 800R XT-P. Follow these instructions carefully to restore firm lever and pedal feel, maintain longevity of seals & hoses, and avoid contamination of ABS components. This procedure assumes basic mechanical skill and common tools; if you encounter ABS faults or persistent sponginess, stop and consult a professional.

What you need

  • DOT 4 brake fluid (clean, fresh, unspecified-brand fluid can damage systems — use quality DOT 4)
  • Clear plastic tubing that fits bleed nipples
  • Catch bottle for old fluid
  • Hand or vacuum brake bleeder (or pressure bleeder) and a helper if using manual two-person method
  • Wrenches for bleed nipples (commonly 8 mm or 10 mm) and tools to remove caliper covers
  • Rags, brake cleaner, safety glasses and gloves
  • Shop manual or service data for fluid capacities and any ABS bleed specifics

Model-specific notes for the 2011 Outlander 800R XT-P

  • The Outlander 800R XT-P typically uses DOT 4 fluid and has reservoir mounted near the right-hand master cylinder for the front and a separate reservoir/line for the rear depending on configuration. Verify which ports feed which calipers before starting.
  • Some 2011 models were equipped with ABS or combined braking features. If your ATV has ABS, the ABS pump/module will require special cycling during bleeding — you may need a diagnostic scanner that can actuate the ABS pump or follow the service manual ABS-bleed routine. Failure to cycle ABS can trap air in the pump.
  • Caliper bleed nipple location can be partially hidden by mud guards or rock plates on XT-P trim. Remove any covers for full access and to prevent contamination while opening the system.
  • Riding in wet, muddy conditions common for XT-P owners accelerates brake fluid contamination and corrosion. Inspect hose ends and caliper bodies closely for swelling, cracking, or seepage and replace any compromised parts.
  • The CVT and engine heat mean the system can be warm; always let the machine cool to ambient before opening the reservoir to avoid cavitation and fluid expansion issues.

Safety and prep

  • Work on a stable, level surface with the ignition off and key removed. Secure wheels so the machine cannot roll.
  • Wear gloves and eye protection; brake fluid is corrosive to paint and plastics. Protect bodywork and clean spills immediately with water & mild detergent, then rinse.
  • Keep the reservoir cap closed except when adding fluid to prevent airborne moisture from entering the system.

Full fluid replacement and bleeding procedure

1. Inspect system before starting

  • Check fluid color in the reservoir. Dark or murky fluid indicates contamination and the need for a full flush.
  • Inspect hoses, calipers, master cylinders and fittings for leaks or damage. Replace any suspect component before bleeding.

2. Lift and secure ATV

  • Raise the machine so wheels hang free or are supported for safe caliper access. Use jack stands or a lift rated for ATVs.

3. Clean the reservoir and surrounding area

  • Wipe the reservoir cap and surrounding area thoroughly before opening to avoid introducing dirt.
  • Remove the cap and diaphragm, cover the opening with a clean rag when not adding fluid.

4. Siphon or remove old fluid from reservoir

  • Siphon out as much old fluid as possible from the reservoir into a waste container. Avoid running the master dry.

5. Refill with fresh DOT 4

  • Top the reservoir with fresh DOT 4 fluid to the specified level. Keep cap loosely on to reduce contamination while working.

6. Bleed order

Use the bleeder sequence to move the most distant caliper first and finish with the closest to the master cylinder. Typical sequence for Outlander 800R layout:

  1. Rear caliper(s) if single-line rear – bleed rear first (often the farthest from reservoir)
  2. Front passenger-side caliper
  3. Front driver-side caliper
  4. If separate rear master, finish with the rear master bleed if applicable

If your model has combined braking or ABS routing differences, consult the machine-specific diagram in the service manual and adapt the sequence accordingly.

7. Bleeding technique — two-person method

  • Attach clear tubing to the bleed nipple and route into a catch bottle partially filled with fresh fluid to prevent air re-entry.
  • Have a helper slowly squeeze the brake lever or press pedal several times, then hold pressure.
  • Open the bleed nipple about 1/4 turn to let fluid and air escape. Close the nipple before the helper releases pressure. Repeat until clear fluid with no bubbles flows.
  • Keep reservoir topped up during the process so it never runs low.

8. Bleeding with a vacuum or pressure bleeder (recommended solo method)

  • Vacuum bleeder: attach vacuum hose to the bleed nipple, draw fluid until clear, keeping reservoir topped up.
  • Pressure bleeder: pressurize the reservoir per tool instructions and open bleed nipples sequentially until fluid runs clear.
  • Both methods reduce air ingestion and are safe for single operators; follow tool safety instructions.

9. ABS-equipped bikes — special steps

  • If your Outlander 800R XT-P has ABS, after bleeding all calipers you must cycle the ABS pump to purge air from the module. This typically requires a diagnostic tool to actuate the pump or following the specific service manual pump-run routine. If you cannot cycle ABS, a trained shop or dealer is recommended.

10. Final checks and cleanup

  • After bleeding each circuit, torque bleed nipple fittings snugly and wipe clean. Avoid overtightening.
  • Top the reservoir to the correct level, reinstall diaphragm and cap, ensuring a proper seal.
  • Operate lever and pedal several times to confirm firmness. Test ride cautiously at low speed to confirm braking performance before normal use.
  • Properly dispose of used brake fluid per local regulations — never reuse or pour on the ground.

Troubleshooting

  • Soft spongy brake feel after bleeding: likely remaining air in the system, missing bleed step (ABS module) or a leak. Re-bleed and inspect for leaks.
  • Persistent ABS warning light: may indicate trapped air in ABS pump or an electrical/sensor fault. Cycle ABS per manual or consult dealer diagnostics.
  • Contaminated fluid returns quickly dark: consider replacing rubber lines and caliper seals, as internal contamination may persist.

Maintenance tips specific to XT-P owners

  • Check and change brake fluid every 1-2 years depending on use & exposure to water/mud. Aggressive trail use accelerates moisture absorption in DOT fluid.
  • After winter storage or heavy wet-season use, inspect and bleed brakes prior to aggressive trail riding.
  • Keep a small spare bleed kit, DOT 4 bottle and rags in your trail pack for emergency topping-up. Never add mineral oil or non-DOT fluids.

Follow these steps for a safe, complete brake fluid replacement and bleed on your 2011 Can-Am Outlander 800R XT-P. If you run into ABS-specific complications or internal component failures, MotoSport recommends professional service to avoid safety risks.
