This MotoSport guide walks you through safely flushing and bleeding the hydraulic brake system on a 2020 Can-Am Outlander MAX 850 XT (MMY CAN_AM;OLM850RXT;2020). Follow each step carefully, use proper PPE, and work in a clean, well-ventilated area. If the bike is ABS-equipped or you are unsure about any step, contact a qualified technician.

Tools & materials

  • DOT 4 brake fluid (clean, unopened container)
  • Clear plastic tubing that fits snugly over bleed nipples
  • Catch bottle for old fluid
  • Wrenches for bleed nipples (usually 8mm-10mm)
  • Brake bleeder kit or hand pump (optional)
  • Torque wrench (for caliper hardware if removed)
  • Shop towels, isopropyl alcohol for cleanup
  • Gloves and eye protection

Important safety & model notes

  • Use DOT 4 only. Do not mix DOT 4 with DOT 5 (silicone) fluid.
  • Brake fluid is hygroscopic — replace every 1-2 years or sooner if brake feel is spongy.
  • Avoid getting fluid on plastics or painted surfaces; it will damage finishes. Wipe spills immediately with isopropyl alcohol.
  • On the 2020 Outlander MAX 850 XT the master cylinder reservoir is under the seat/center panel area — remove the seat and clean around the cap before opening to prevent contamination.
  • If your machine has ABS or an electronic brake aid, follow factory service instructions for cycling ABS components or have the system bled by a dealer to avoid introducing air into modulators.
  • Always bleed the caliper farthest from the master cylinder first, then work toward the closest caliper. For this Can-Am that typically means: rear right, rear left (if dual rear), front right, front left. Confirm by visual inspection of brake-line routing to identify the master cylinder feed.

Preparation

  1. Park on level ground and secure the machine on stands so wheels can turn freely. Chock wheels if needed.
  2. Remove the seat and any panels needed to access the master cylinder reservoir. Clean the reservoir cap area thoroughly.
  3. Inspect brake lines, hoses, and calipers for leaks or damage. Replace any damaged components before bleeding.
  4. Top up the reservoir with fresh DOT 4 fluid to the maximum mark, leaving the cap loose but sealed with its diaphragm to limit contamination.

Bleeding procedure (single caliper at a time)

  1. Start with the caliper farthest from the master cylinder.
  2. Place a clear tube over the caliper bleed nipple. Submerge the other end in a catch bottle partially filled with fresh fluid to prevent air re-entry.
  3. Have an assistant slowly depress the brake lever or pedal several times and hold it down. If using a hand pump bleeder, follow the tool instructions.
  4. With the lever/pedal held down, open the bleed nipple about a quarter to half turn until fluid flows through the tube. Close the nipple before the assistant releases the lever/pedal to avoid sucking air back in.
  5. Repeat the pump-open-close cycle until the fluid runs clear and bubble-free, and fresh fluid appears. Keep the master reservoir topped up during the entire process to avoid drawing air into the system.
  6. When finished with that caliper, tighten the bleed nipple snugly (avoid over-torquing), wipe clean, and move to the next farthest caliper.
  7. Repeat for each caliper following the correct sequence toward the master cylinder.

Final checks

  • Ensure the reservoir is filled to the proper level and reinstall the cap/diaphragm securely.
  • Operate the brake lever/pedal several times to confirm a firm feel. If it feels spongy, repeat the bleeding process.
  • Check bleed nipple tightness and inspect for leaks while applying steady brake pressure.
  • Dispose of old fluid per local hazardous-waste regulations.
  • Reinstall any panels/seat removed for access and test-ride at low speed to confirm braking performance before normal use.

Torque & fitment notes specific to the Outlander MAX 850 XT

  • If you remove calipers or brake hardware, tighten caliper mounting bolts to factory torque specs (consult your service manual for exact values). MotoSport recommends confirming these values in the repair manual for the model year.
  • Inspect the parking brake/handbrake (if equipped on MAX models) for proper function after bleeding rear circuits.

Troubleshooting

  • Persistent spongy lever after bleeding: suspect trapped air in ABS modulators or internal master cylinder leak. Service by a dealer or a brake specialist.
  • Brake drag after bleeding: check caliper pistons and pads for proper retraction and ensure no hoses collapsed during the procedure.
  • Fluid level rapidly dropping: inspect for external leaks at calipers, lines, master cylinder, and fittings.

Regular brake-fluid replacement and inspection are essential to maintain the stopping performance of your 2020 Can-Am Outlander MAX 850 XT. When in doubt, have brakes serviced by a qualified technician to protect you and your machine.
