How to Bleed & Replace Brake Fluid on a 2017 Can-Am Outlander 850 X MR

Shop parts for a 2017 CAN-AM OL850XMR ATV.

This MotoSport-exclusive service procedure covers safe, complete brake fluid replacement and bleeding on the 2017 Can-Am Outlander 850 X MR. Follow these steps precisely, use recommended fluids and tools, and only perform the job on a cool, level machine with the parking brake engaged.

What you need

  • DOT 4 brake fluid (manufacturer-recommended spec)
  • Clear tubing and catch bottle
  • Wrench that fits bleed nipples (usually 8mm or 10mm)
  • Turkey baster or fluid syringe for reservoir removal
  • Brake bleeder pump or vacuum pump (optional but recommended)
  • Clean lint-free rags, gloves, safety glasses
  • Service manual or notepad to record steps
  • Jack and stands if needed to access calipers

Model-specific notes for the 2017 Outlander 850 X MR

  • This model uses hydraulic disc brakes and requires DOT 4 fluid. Do not mix fluid types.
  • The brake master cylinder reservoir is mounted on the handlebar area and feeds both front & rear circuits on most Outlanders; confirm reservoir orientation before starting.
  • The 2017 X MR typically does not have wheel ABS hardware like larger road vehicles, but some regional configurations may include sensor wiring near calipers — avoid damaging it while working.
  • Brake lines and fittings on this machine are routed for off-road use; inspect for chafing, mud intrusion and age-related cracking while servicing.
  • Brake fluid eats paint and plastics — protect painted surfaces and immediately clean any spills.

Preparation

  • Park the ATV on level ground, engine off, key out. Secure the machine so it won't roll.
  • Clean the reservoir cap and surrounding area to prevent contamination when opened.
  • Remove old fluid from the reservoir with a turkey baster or syringe until level is low but not empty. Keep some fluid in the reservoir to avoid drawing air into the master cylinder.
  • Top up with fresh DOT 4 to the full mark.
  • Identify bleed nipples on each caliper and loosen dust caps. If you have a service manual, confirm the order of calipers; if not, use the farthest-from-reservoir-first rule.

Bleeding sequence (general rule: farthest to nearest)

On most Outlander setups the typical order is: rear caliper(s) first, then front caliper(s). If the master reservoir feeds a single circuit separately to each caliper, prioritize the caliper farthest from the master cylinder.

Two-person pump-and-hold method

  1. Person A sits on the ATV and lightly pumps the brake lever/pedal several times and holds firm pressure.
  2. Person B fits clear tubing over the bleed nipple, places the other end in a catch bottle partly filled with fresh fluid to avoid drawing air back in.
  3. Person B cracks the bleed nipple about a quarter turn. Fluid and air will flow into the tubing. When flow slows, close the nipple.
  4. Person A releases the lever/pedal slowly and repeats pump-and-hold. Repeat until only clean fluid with no bubbles appears, then tighten the nipple to spec snugness.
  5. Keep the reservoir topped up during the entire process to prevent air from entering the master cylinder.
  6. Move to the next caliper and repeat until all calipers are bled. After final caliper, verify lever/pedal firmness and full travel.

One-person vacuum/pressure method

  1. Connect a vacuum bleeder to each bleed nipple in turn or attach a pressure bleeder to the master reservoir per tool instructions.
  2. Open the bleed nipple while pulling vacuum or under pressure so fluid flows into the catch container until clear and bubble-free.
  3. Close the nipple, then move to the next caliper. Maintain reservoir level throughout.

Finishing steps

  • Top the reservoir to the proper mark with fresh DOT 4 and reinstall the cap securely.
  • Clean all fittings, remove tools and stands, and operate the brake lever/pedal multiple times to confirm firm feel and proper travel.
  • Inspect for leaks at banjo bolts and bleed nipples. Recheck torque on banjo bolts after a short test ride if you disturbed them while servicing.
  • Dispose of old brake fluid per local regulations. Do not reuse waste fluid.
  • Test ride cautiously at low speed to verify braking performance before normal use.

Troubleshooting & tips

  • If the lever/pedal stays spongy after bleeding, repeat the full sequence ensuring the reservoir never runs low and that you bled from the correct far-to-near order.
  • If air persists, consider bench-bleeding the master cylinder or replacing rubber lines if they are swollen or collapsed.
  • Protect plastic trim and painted surfaces from spilled fluid using rags and tape; brake fluid will damage finishes.
  • Keep a record of brake fluid change interval; for heavy off-road use, inspect and replace fluid more often to prevent moisture buildup.

Safety reminders

  • Wear eye protection and gloves. Brake fluid is corrosive to skin and eyes.
  • Never mix DOT 4 with DOT 5 silicone fluid; always use manufacturer-recommended fluid.
  • If unsure about any step, contact a certified technician or a MotoSport service specialist for assistance.

Performing a full fluid replacement and bleed is a maintenance task that restores pedal/lever feel and extends brake component life. Keep the 2017 Can-Am Outlander 850 X MR's brake system clean, use DOT 4, and follow the far-to-near bleeding sequence for best results.
