How to Bleed & Replace Brake Fluid on a 2015 Can-Am Outlander 650 6X6 XT

Shop parts for a 2015 Can-Am Outlander 650 6X6 XT ATV.

This MotoSport guide walks you through a professional, reliable brake fluid change and bleed for the 2015 Can-Am Outlander 650 6X6 XT. Follow these steps carefully to maintain safe stopping performance and protect brake system components.

What you need

  • DOT 4 brake fluid (do not mix with DOT 3 or DOT 5 silicon fluid)
  • Clear plastic tubing that fits snug on bleeder nipples
  • Brake-bleeder wrench or appropriately sized box wrench
  • Clean catch bottle or jar
  • Hand vacuum pump or two-person helper
  • Syringe or turkey baster for reservoir fluid removal
  • Clean rags, isopropyl alcohol, and a small funnel or reservoir filter cap
  • Jack, stands, or ramps rated for the 6X6 to safely support the machine
  • Latex gloves and eye protection

Important model notes for the 2015 Can-Am Outlander 650 6X6 XT

  • The 6X6 layout increases payload & weight on the chassis; brakes may require more frequent inspection under heavy-use conditions.
  • The Outlander 650 6X6 XT typically uses DOT 4 brake fluidconfirm fluid printed on the reservoir cap on your machine before refilling.
  • There are separate calipers/circuits for front and rear on this model; bleed each hydraulic circuit independently. Identify which master cylinder feeds which calipers before starting.
  • Paint and body plastics are sensitive to brake fluid. Immediately wipe any spills with isopropyl alcohol and water.
  • If your machine has a factory parking brake or mechanical cable on the rear, verify cable adjustment after bleeding to ensure proper parking function.

Safety first

  • Park on level ground, block wheels, remove key, and disconnect the negative battery terminal if you will be working near electrical components.
  • Support the ATV securely so wheels can rotate freely if you will be pumping calipers during bleeding.
  • Brake fluid is corrosive to paint. Keep rags handy and protect painted surfaces.

Step-by-step procedure

1. Inspect & identify system layout

Locate the brake fluid reservoir(s) on the Outlander 650 6X6 XT. Many Can-Am units have a single master reservoir with lines to front and rear calipers. Trace hoses to determine which calipers belong to each circuit. Plan to bleed one circuit at a time.

2. Clean the reservoir & remove old fluid

  1. Clean the area around the reservoir cap thoroughly to prevent contamination.
  2. Remove the cap and diaphragm; use a turkey baster or syringe to extract as much old fluid as possible from the reservoir.
  3. Wipe the inside of the cap and rim clean. Reinstall the cap loosely to limit contamination while you work.

3. Top with fresh fluid

Pour fresh DOT 4 fluid into the reservoir until it reaches the maximum level. Keep the cap off while bleeding but refill frequently to prevent air ingress.

4. Bleeding order & method

Use the furthest caliper from the master cylinder first, then progress to the closest. On the Outlander 6X6 XT the typical sequence is:

  • Rear-most caliper (if multiple rear calipers, start with the one farthest from the master cylinder)
  • Other rear caliper(s)
  • Front caliper(s), furthest to nearest

Use either a hand vacuum pump attached to the bleeder nipple or a two-person bleed (one pumps the lever/pedal, the other opens & closes the nipple). Recommended technique:

  1. Attach clear tubing to the bleeder nipple and route into a catch bottle partially filled with a little fresh brake fluid to prevent air re-entry.
  2. Crack the bleeder nipple ~1/4 turn. If using a vacuum pump, create vacuum and open the nipple to draw fluid until clear, bubble-free fluid flows. If two-person, have the rider depress the pedal or lever slowly while the helper opens the nipple to let fluid & air out, then closes it before the lever returns.
  3. After each cycle, top the master reservoir back to max to keep air out of the system.
  4. Repeat until only clean fluid flows and no air bubbles are visible in the tubing.
  5. Tighten the bleeder nipple to spec snugness (do not overtighten). Wipe and recheck the level.

5. Repeat for every caliper/circuit

Work through the sequence for each circuit. If the Outlander has dual circuits or a separate parking brake hydraulic circuit, bleed each independently and follow the same furthest-to-nearest rule for each circuit.

6. Final checks

  • Ensure reservoir is filled to the proper level and reinstall cap & diaphragm securely.
  • Operate the brake lever and pedal multiple times to confirm a firm, consistent feel. If spongy, re-bleed the affected circuit.
  • Inspect all fittings, lines, and calipers for leaks while pressure is applied.
  • Test-ride at slow speed in a safe area to verify braking performance before normal operation.

Tips & troubleshooting

  • If you continually get air or soft pedal feel, inspect flexible hoses for internal collapse and master cylinder seals for wearboth can allow air or reduce pressure.
  • Never reuse drained brake fluid. Dispose of old fluid according to local hazardous waste rules.
  • If the system contains stubborn air, consider bench-bleeding the master cylinder (remove and bleed on a bench) or using a pressure bleeder designed for ATVs.
  • Record the date and mileage when you replace fluid. For heavy use, change every 1-2 years; otherwise every 2-3 years helps prevent moisture-related corrosion and boiling under load.

When to seek professional help

  • If you cannot obtain a firm pedal/lever after multiple bleed cycles.
  • If you find damaged lines, corroded calipers, or master cylinder issues.
  • If you're unsure which caliper belongs to which circuit on your specific 6X6 layout.

Following this MotoSport procedure will keep your 2015 Can-Am Outlander 650 6X6 XT stopping reliably. Replace fluid carefully, protect painted surfaces, and verify brake function before heavy use.
