How to Bleed & Replace Brake Fluid on a 2016 Can-Am Outlander 650 6X6 XT

Shop parts for a 2016 Can-Am Outlander 650 6X6 XT ATV.

This MotoSport proprietary guide walks you through flushing the entire brake system on a 2016 Can-Am Outlander 650 6X6 XT, plus model-specific notes owners should know. Follow every safety step – brake fluid is corrosive, flammable, and absorbs water. If you’re unsure at any point, contact a qualified ATV technician.

What you’ll need

  • DOT 4 brake fluid (clean, unopened container)
  • Clear tubing that fits bleed nipples
  • Brake fluid catch bottle
  • Wrenches to fit bleed nipples (open-end or flare nut)
  • Rubber gloves, safety glasses, shop rags
  • Helper (recommended) or vacuum bleeder/pressure bleeder
  • Small turkey baster or fluid syringe
  • Torque wrench for caliper/bleeder hardware (see service manual)
  • Jack or stands if needed to access wheels

Safety & preliminary steps

  • Work on a level surface, engine off, key removed, parking brake applied.
  • Protect paint & plastics — brake fluid will damage finishes. Cover bodywork where you remove the reservoir cap.
  • Locate the master cylinder reservoir. On the Outlander 650 6X6 XT this is accessible after removing the seat or front storage panel depending on trim & rack setup. Clean the cap area before opening to avoid contamination.
  • Use DOT 4 only. Do not mix DOT 5 (silicone) with DOT 4.

Overview & bleed order

The Outlander 650 6X6 XT uses hydraulic brakes with multiple calipers. Bleed the system starting with the caliper farthest from the master cylinder, then proceed to the next-farthest, ending with the caliper closest to the master cylinder. For most 6X6 layouts this typically means:

  1. Rear-most caliper on the far side (right or left depending on reservoir location)
  2. Rear caliper on the near side
  3. Middle/secondary rear axle calipers (if applicable) moving toward the front
  4. Front calipers, finishing with the caliper closest to the master cylinder

If you are unsure which caliper is farthest from the master cylinder, trace the brake line from the reservoir to identify routing and follow that logic.

Step-by-step fluid replacement & bleeding

  1. Open the reservoir. Use a clean rag to remove old debris. Siphon as much old fluid as possible with a turkey baster into a sealed waste container for proper disposal.
  2. Top the reservoir with fresh DOT 4 fluid until just below the max mark. Keep the cap loose while bleeding to avoid vacuum.
  3. Start at the farthest caliper. Fit clear tubing over the bleed nipple and submerge the other end in a catch bottle partially filled with fresh fluid to avoid air re-entry.
  4. With a helper: have them slowly pump the brake lever/pedal several times and hold pressure. Open the bleed nipple about a 1/4 turn to let fluid &air out, then close the nipple before the helper releases the lever. Repeat until fluid runs clear with no air bubbles. Keep checking & topping the reservoir frequently to prevent it going low.
  5. If using a vacuum or pressure bleeder: attach the tool at the caliper or reservoir per the tool instructions and operate until no air bubbles appear. Maintain reservoir level throughout.
  6. Move to the next caliper in the bleed order. Repeat the same procedure for every caliper until all lines are clear and only clean DOT 4 flows from each bleed nipple.
  7. After bleeding all calipers, ensure the reservoir is filled to the proper level, reinstall & tighten the cap, and wipe any spilled fluid. Torque bleed nipples and banjo bolts per the service manual values.
  8. Check lever/pedal feel — it should be firm and consistent. If it feels spongy, repeat bleeding or inspect for leaks or a compromised master cylinder.
  9. Carefully test the ATV at low speed in a safe area to confirm braking performance. Recheck fluid level after the first ride and inspect for leaks.

Model-specific notes for the 2016 Can-Am Outlander 650 6X6 XT

  • Reservoir access can be restricted by cargo racks or accessories. Remove any racks or panels that block access to the master cylinder to avoid contaminating the system while working.
  • The 6X6 configuration places extra load on rear brakes when hauling or towing. Inspect rear calipers, pads & lines more frequently than on two-wheel-drive models, especially if you use the dump bed or tow heavy loads.
  • Some Outlander 6X6s use dual-circuit or split braking; ensure you bleed all circuits completely. Trace both circuits before starting so you don’t miss an inline valve or T-fitting unique to this chassis.
  • Brake hoses are routed to accommodate articulating bed and rear axles. After reassembly, cycle the suspension and bed while checking hoses for binding or rubbing that could cause premature wear or leaks.
  • If your model has an accessory parking brake, check its adjustment after the flush. Parking brake components can be under extra stress on 6X6 platforms and may need periodic adjustment or replacement.
  • Service manual references: always use the Can-Am torque specs for caliper bolts, banjo fittings, and bleed nipple tightening. Improper torque can cause leaks or damaged threads.
  • Brake fluid is hygroscopic; plan to flush the system every 12–24 months depending on use and exposure to water or heavy-duty service conditions.

Troubleshooting quick tips

  • Persistent air: double-check hose connections, clamp on the bleed tube, and that the reservoir never ran dry during bleeding.
  • Soft lever after bleeding: inspect master cylinder seals, caliper pistons, and for internal leaks. Aging master cylinders can allow air in even after proper bleeding.
  • Visible leaks: replace leaking hoses, banjo rings, or caliper seals. Do not ride until repaired.

Performing a full brake fluid replacement on a 2016 Can-Am Outlander 650 6X6 XT restores braking reliability and extends component life. When in doubt on part numbers or service specifications, source exact replacement parts and torque figures from MotoSport’s parts listing for your specific MMY or contact a certified dealer.
