This step-by-step MotoSport guide shows how to flush and bleed the brake system on a 2020 Can-Am Outlander 850 safely and effectively. Follow these instructions precisely, use correct fluid, and observe safety precautions for ATV work. This guide is written specifically for the Outlander 850 platform and includes model-specific notes where they matter.

What you’ll need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear plastic bleed tubing
  • Brake fluid collection bottle or jar
  • Box-end wrench to fit bleed nipples (typically 8 mm or 10 mm)
  • Spare clean rags and nitrile gloves
  • Small turkey baster or syringe (for reservoir removal)
  • Jack or stands to keep the ATV level and stable
  • Torque wrench for caliper and wheel hardware
  • Plastic funnel and a clean container for used fluid disposal

Safety & preliminary checks

  • Work on a flat, stable surface with the engine off and key removed.
  • Wear eye protection and gloves. Brake fluid damages paint & plastics; protect finish.
  • Confirm your Outlander 850 does or does not have ABS. If ABS is fitted, check the service manual for any ABS-specific bleed procedures. MotoSport recommends consulting dealer service if ABS intervention or active cycling is required.
  • Inspect lines, hoses & calipers for leaks or damage. Replace any cracked components before bleeding.

Model-specific notes for the 2020 Can-Am Outlander 850

  • The Outlander 850 uses DOT 4 brake fluid from the factory. Do not mix DOT 5 silicone fluids with DOT 4.
  • Reservoir orientation can be high on the front area near the handlebars and may have a diaphragm cap – keep the cap secure between steps to avoid contamination.
  • If your machine has electronically controlled systems (ABS or traction), MotoSport advises checking for stored fault codes after bleeding and confirming system self-tests run correctly on first start.
  • Some model years use separate front and rear master cylinders or combined master with proportioning. Identify your system layout before starting so you can apply the correct bleeding sequence.

Recommended bleed sequence

Bleed starting with the caliper farthest from the master cylinder and finish with the closest. Typical sequence on the Outlander 850 without unusual routing:

  1. Rear passenger (right) caliper
  2. Rear driver (left) caliper
  3. Front passenger (right) caliper
  4. Front driver (left) caliper

Step-by-step fluid replacement & bleeding

  1. Clean the reservoir cap area thoroughly. Remove cap and diaphragm, then suction out old fluid with syringe until reservoir is near empty but not bone dry.
  2. Top reservoir with fresh DOT 4 fluid so it’s about 3/4 full. Keep the cap loosely in place to avoid contamination.
  3. Start with the farthest caliper. Fit clear tubing onto the bleed nipple and the other end into a bottle partly filled with some fresh fluid to prevent air from reentering. Loosen bleed nipple about a 1/4 to 1/2 turn.
  4. Have an assistant slowly pull the brake lever or pedal to the firm position and hold. Open the bleed nipple slightly to allow fluid & air to flow into the tubing. Close the nipple before the lever/pedal is released. Repeat until no bubbles appear in the tubing and fluid runs clear and clean.
  5. Keep the reservoir topped up during the process to prevent air from being drawn into the master cylinder. Refill frequently with fresh DOT 4.
  6. Torque the bleed nipple to spec (light snug; avoid over-torquing) and move to the next caliper following the sequence above.
  7. After all calipers bleed, perform several firm brake lever/pedal applications to confirm firmness. If spongy feel remains, repeat bleeding focusing on locations where bubbles were observed.
  8. With bike level and wheels on the ground, test brakes at low speed in a controlled area to confirm operation. Check for leaks and ensure consistent pressure.

Bench bleeding or one-man methods

  • If working alone use a one-way valve kit or a pressure/vacuum bleeder designed for DOT fluids. MotoSport prefers a pressure bleeder for speed and reliability on ATVs.
  • Do not pump the master cylinder aggressively without confirming reservoir level – that can pull air from the reservoir cap or damage seals.

Post-bleed checks & maintenance tips

  • Wipe any spilled fluid immediately with water & mild detergent then rinse – brake fluid is corrosive to paint and plastic.
  • Dispose of used fluid responsibly at a hazardous waste facility.
  • Inspect rotor condition, pad thickness, and caliper hardware while wheels are off. Replace pads if thickness is near service limit.
  • Record the date and miles/hours of fluid replacement. MotoSport recommends brake fluid changes every 2 years or sooner if moisture exposure is likely.
  • If ABS is fitted, verify the ABS indicator behavior and run a system check if available. If ABS faults appear, do not ride until resolved.

Troubleshooting

  • Stiff lever suddenly becomes soft after bleeding: likely air remains or master cylinder seal issue — re-bleed and inspect master.
  • Persistent bubbles during bleed: check for soft hoses or a leaking master cylinder cap allowing air drawback.
  • Brake fade after heavy use: consider contaminated rotors or glazed pads; flush fluid if overheated, and replace pads/rotors as needed.

Following this MotoSport procedure will restore braking performance and keep your 2020 Can-Am Outlander 850 safe and confidence-inspiring on trail or work. If you encounter ABS-related complications or major hydraulic leaks, consult a certified Can-Am service center.
