This MotoSport proprietary guide walks you through safely replacing brake fluid and bleeding the hydraulic system on a 2019 Can-Am Outlander 650. It covers preparation, step-by-step flushing and bleeding, tips specific to the Outlander platform, and safety notes to protect components and keep braking performance crisp.

What you need

  • DOT 4 brake fluid (fresh, unopened bottle)
  • Clear plastic bleed tubing sized to the bleeder nipple
  • Catch bottle for old fluid
  • 7 mm or 8 mm wrench for bleeder nipples (verify size by inspection)
  • Turkey baster or fluid transfer pump (for removing fluid from reservoir)
  • Shop rags, nitrile gloves, safety glasses
  • Jack or ramps and axle stands (if needed to access calipers)
  • Assistant for manual bleeding (or a one-person vacuum/pressure bleeder)
  • Torque wrench for reassembly if you remove calipers or lines

Model notes — what owners of the 2019 Outlander 650 should know

  • The Outlander 650 uses a hydraulic braking system with a master cylinder and reservoir accessible after removing the appropriate plastic cover near the handlebars; some models have a remote reservoir under the dash area. Locate and inspect the reservoir cap and rubber diaphragm before starting.
  • DOT 4 is the recommended fluid for this model; do not mix DOT 3, DOT 4, and DOT 5 (silicone). Always use fresh, sealed fluid to avoid moisture contamination.
  • This ATV may use a split hydraulic circuit (front/rear) or combined master cylinder with separate circuits; bleeding order and procedure below are compatible with both configurations, but verify circuit routing visually before starting.
  • Several Outlander trims have integrated parking brake mechanisms and caliper parking brake hardware at the rear; do not attempt to loosen or force parking-brake-specific components without first releasing the parking brake per the owner's procedure.
  • ABS is not present on many Outlander 650 models; if your machine has any additional electronic brake components, follow manufacturer service procedures or bring it to a dealer for service.

Safety first

  • Work on a level surface with the engine off and key removed.
  • Keep brake fluid off painted surfaces &ndash it damages paint. Clean spills immediately and rinse with water.
  • Wear gloves & eye protection. Brake fluid is harmful to skin and eyes.
  • Dispose of used fluid per local regulations.

Preparation

  1. Park the Outlander and secure it on a flat, stable surface. Use a center stand or jack stands so wheels can be moved slightly during bleeding, if needed.
  2. Remove any plastic covers required to access the master cylinder reservoir and calipers.
  3. Clean the reservoir cap area to prevent contamination when opening. Remove the reservoir cap and diaphragm, then use a turkey baster or pump to remove old fluid to lower the fluid level in the reservoir to just above the minimum mark.
  4. Top off the reservoir with fresh DOT 4 fluid to the specified level and replace the cap loosely to reduce dirt ingress. Keep the reservoir topped during the bleed to avoid introducing air.
  5. Identify bleeder nipples on each caliper. On many Outlanders: two front calipers (left & right) and one rear caliper. Determine the routing so you can bleed the farthest caliper from the master cylinder first.

Bleeding strategy — proven order

Use the farthest-to-closest method (from master cylinder):

  1. Right front (farthest) caliper
  2. Left front caliper
  3. Rear caliper (closest)

If your Outlander has a divided circuit, bleed each circuit separately following farthest-to-closest within that circuit.

Manual two-person bleeding procedure

  1. Fit clear tubing over the bleeder nipple and place other end into a catch bottle partially filled with used fluid to prevent air being drawn back in.
  2. Have your assistant sit on the machine and slowly depress the brake lever or pedal several times, then hold firm pressure (do not pump aggressively).
  3. With pressure applied, open the bleeder nipple one-quarter to one-half turn until fluid and air bubbles flow into the tube. Close the nipple before your assistant releases the lever to prevent air re-entry.
  4. Repeat the pump-hold-open-close sequence until you see only clear fluid with no bubbles. Periodically top up the reservoir to keep it above the minimum level.
  5. Move to the next caliper in the sequence and repeat. Always finish with the caliper closest to the master cylinder.

One-person vacuum or pressure bleeder method

  1. If using a vacuum bleeder, attach the vacuum hose to the bleeder nipple, open the nipple, and let the tool draw fluid until clear fluid without bubbles appears. Close the nipple and move to the next caliper.
  2. If using a pressure bleeder on the master cylinder, follow the tool manufacturer's procedure. Inflate the bleeder to the recommended low pressure, then open bleeders in sequence farthest-to-closest until clear fluid appears.

Full fluid replacement (flushing)

  1. Repeat the bleeding sequence described above while periodically removing old fluid from the reservoir and refilling with fresh DOT 4. Continue until the fluid exiting bleeders tests clean and new in color.
  2. When finished, ensure reservoir fluid is at the correct level, reinstall the diaphragm and cap, and secure any covers removed for access.

Final checks

  • Check lever and pedal feel &ndash firm and consistent with no sponginess. If spongy, additional bleeding cycles are needed.
  • Inspect bleeder nipples and fittings for leaks, then torque to spec if you removed caliper hardware (consult service manual for torque values).
  • Confirm parking brake operation and any rear brake parking-mechanism adjustment if present.
  • Test ride slowly in a safe area to verify braking performance before normal use.

Troubleshooting

  • Persistent spongy lever: likely trapped air or contaminated master cylinder seal & reservoir. Re-bleed carefully; if problem persists, inspect master cylinder for internal leaks.
  • Leaking bleeder: replace bleeder screw or damaged sealing surfaces; use copper crush washers if applicable.
  • Contaminated or discolored caliper fluid only clearing after repeated flushes: consider caliper rebuild or professional inspection.

MotoSport maintenance tips for Outlander 650 owners

  • Bleed and replace brake fluid every 2 years or sooner if the machine is used in wet/muddy conditions or heavy-duty use; moisture absorption reduces boiling point and performance.
  • Keep an extra bottle of DOT 4 and a small bleed kit in your garage for quick maintenance. Use sealed containers to prevent moisture pickup.
  • Record the date and mileage/hours when fluid is changed to maintain a proper service log.

Following this MotoSport-exclusive procedure will keep your 2019 Can-Am Outlander 650 braking reliably responsive and safe. If you encounter unusual hardware, ABS/electronic brake components, or persistent issues, consult a certified technician.
