This MotoSport guide walks you through safely flushing and bleeding the brake system on a 2020 Can-Am Outlander 850 XT-P. Follow these steps carefully, use DOT 4 brake fluid only, and always wear eye protection and gloves. If you are unsure at any point, contact a certified technician.

What you need

  • DOT 4 brake fluid (new, unopened)
  • Brake bleeding kit: clear hose & catch bottle or vacuum/pressure bleeder
  • Turkey baster or fluid siphon
  • Wrenches for bleeder nipples (typical sizes 8mm-10mm)
  • Clean rags, brake cleaner, disposable container for old fluid
  • Torque wrench for caliper fasteners (use factory specs)
  • Jack or stands to lift the ATV safely (park on level surface, chock wheels)

Model notes specific to the 2020 Outlander 850 XT-P

  • The Outlander 850 XT-P uses a Rotax 850 V-twin and a conventional hydraulic brake system without factory ABS on most trims – bleeding is standard hydraulic procedure. Confirm your specific MMY has no ABS before attempting hydraulic-only bleeding.
  • Brake reservoirs may be under a handlebar cover (front lever reservoir) and a separate reservoir near the rear brake pedal or integrated unit depending on configuration. Confirm location and cap type before opening.
  • Brake fluid is hygroscopic. MotoSport recommends replacing brake fluid every two years or sooner if contamination is suspected, especially if riding in wet or coastal environments.
  • Protect painted surfaces and plastics from spilled fluid — DOT fluid damages finishes. Clean spills immediately with water and brake cleaner as appropriate.

Preparation

  • Park on level ground, set parking brake, and disconnect the negative battery terminal to prevent accidental starts.
  • Clean around reservoir caps to keep contaminants out. Inspect hoses, calipers, and brake lines for leaks or damage; replace damaged parts before bleeding.
  • Raise the ATV if needed to access calipers comfortably and to spin wheels by hand for pedal/lever feel checks.

System layout & bleed order (general rule)

Bleed the brake calipers from the farthest from the master cylinder to the nearest. On most Outlander 850 setups this typically means:

  • Rear caliper first
  • Right/front caliper next (farthest front side)
  • Left/front caliper last (nearest master cylinder)

Confirm master cylinder location on your machine; follow farthest-to-nearest logic if layout differs.

Step-by-step fluid replacement & bleeding

  1. Remove the reservoir cap(s) and diaphragm. Siphon or turkey-baste as much old fluid out of the reservoir as possible without introducing air into the system. Wipe the cap area clean.
  2. Top the reservoir with fresh DOT 4 fluid to the recommended fill line. Keep the cap loosely in place between steps to limit contamination.
  3. Start at the farthest caliper. Fit a clear hose over the bleeder nipple and submerge the other end in a small, clear catch bottle partially filled with fresh fluid to prevent air draw back.
  4. Have an assistant slowly operate the brake lever/pedal several times and hold pressure on the lever/pedal. While pressure is held, open the bleeder about a quarter turn until fluid flows into the hose, then close the nipple before the assistant releases pressure. Repeat until clear, bubble-free fluid comes out and nothing darker than new fluid is present.
  5. Keep the reservoir level topped with fresh fluid during the process to avoid drawing air into the master cylinder. Never let the reservoir run dry.
  6. Move to the next caliper in the bleed order and repeat the procedure until all calipers show clean fluid and no air.
  7. After the final caliper is bled, pump the brake lever/pedal to build firm pressure. Inspect the feel & travel. If sponginess remains, repeat bleeding sequence or use a pressure/vacuum bleeder for more thorough results.
  8. Tighten all bleeder nipples snugly after bleeding. Do not overtighten; finish to factory torque if available. Reinstall reservoir diaphragm & cap securely.
  9. Clean any spilled fluid, lower the ATV, reconnect battery, and perform a short low-speed test in a safe area to confirm firm braking. Recheck reservoir level after a brief ride and top as needed.

Using a pressure or vacuum bleeder

Pressure or vacuum systems make this job cleaner and faster. Attach the pressure bleeder to the reservoir cap or use the vacuum hose at each bleeder. Follow your bleeder tool manufacturer instructions and still follow the farthest-to-nearest bleed sequence. Monitor fluid level in the reservoir to avoid air entry.

Aftercare & disposal

  • Wipe down components with brake cleaner; inspect lines and fittings for leaks after the test ride.
  • Dispose of used brake fluid according to local hazardous waste regulations — do not pour it down drains.
  • Record the service date and fluid type on your maintenance log.

Troubleshooting

  • Persistent spongy brake pedal/lever: re-bleed system, paying attention to the master cylinder area. Consider bench-bleeding the master cylinder if air is trapped there.
  • If fluid returns dirty immediately after replacement, inspect internal caliper seals or master cylinder for contamination or breakdown — replace parts as needed.
  • If you suspect ABS or electrical brake-assist components on your specific MMY, stop and consult the factory service manual or a dealer; special bleeding procedures may be required.

Performing a full brake fluid flush and bleed restores pedal/lever feel & braking performance. MotoSport recommends checking brakes frequently, using DOT 4 fluid, and replacing fluid at least every two years for reliable stopping power.
