This MotoSport-exclusive guide walks you step-by-step through replacing the brake fluid and properly bleeding the braking system on a 2008 Can-Am Outlander 650 XT. Follow these instructions carefully to restore firm braking performance and prevent air or contaminated fluid from compromising safety.

What you’ll need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear plastic hose that fits bleed nipples
  • Catch bottle or jar for old fluid
  • 10-12 mm wrench for bleeder nipples (verify size on your bike)
  • Phillips & flat screwdrivers to open reservoir covers
  • Clean rags and isopropyl alcohol for cleanup
  • Rubber gloves and eye protection
  • Helper (recommended) or a vacuum/pressure bleed kit
  • Service manual for torque specs & bleed point locations (MotoSport recommends keeping one with your tools)

Model-specific notes for the 2008 Outlander 650 XT

  • The Outlander 650 XT uses hydraulic front brakes and a separate rear master cylinder for the foot brake. You must service both systems individually.
  • The front brake master cylinder is on the handlebar; the rear master cylinder is mounted near the foot brake lever. Each reservoir has its own cap and level window.
  • This model typically calls for DOT 4 fluid. Do not mix with DOT 5 (silicone) fluid.
  • Brake lines on this model are routed across the frame and hubs; inspect for chafing, leaks, or swollen hoses while you work.
  • If your Outlander has aftermarket calipers or braided lines, follow the manufacturer bleed recommendations but keep fluid type consistent (DOT 4 unless specified otherwise).

Safety first

  • Work on a flat, stable surface with the engine off and parking brake engaged where applicable.
  • Avoid spilling brake fluid on painted surfaces – it damages finishes. Wipe spills immediately with alcohol.
  • Dispose of used fluid per local regulations.

Preparation

  1. Raise the ATV on a stand so wheels can rotate freely, if needed, and ensure it’s stable.
  2. Clean around each reservoir cap before opening to prevent contamination.
  3. Open the front master cylinder reservoir (handlebar) and the rear reservoir (near foot lever) as needed, keeping caps and diaphragms in place where possible to limit dirt entry.
  4. Top reservoirs to the specified level with fresh DOT 4 fluid before starting; do not overfill.

Bleed sequence

Bleed the lines from the wheel farthest from the master cylinder first, moving to the closest. For the Outlander 650 XT:

  • Front system: bleed the right front caliper first, then the left front caliper (far to near relative to front master cylinder on handlebar).
  • Rear system (separate master): bleed the rear caliper(s) after the front system is complete.

Manual pump-and-hold bleed method (with helper)

  1. Have your helper sit on the seat and slowly pump the brake lever (or press foot pedal for rear) several times, then hold firm pressure.
  2. Attach clear hose to the bleeder nipple on the caliper and place the other end into a catch bottle partially filled with clean fluid to prevent air re-entry.
  3. Open the bleeder nipple about a quarter turn. Fluid and air will flow into the tube. Close the nipple before your helper releases pressure.
  4. Repeat: pump, hold, open, close until only clear fluid with no bubbles flows and lever/pedal feels firm.
  5. Keep reservoir topped to avoid introducing air; never let it run dry.
  6. Work through bleed sequence: right front, left front, then rear.

Vacuum or pressure bleed method (single tech)

  1. Attach your vacuum/pressure kit per manufacturer instructions to the bleeder nipple and reservoir respectively.
  2. Draw fluid through until clear, bubble-free fluid appears; monitor reservoir level and top as needed.
  3. Repeat for each bleed point in the same sequence, finishing with the reservoir filled to the recommended level and cap secured.

After bleeding

  • Wipe all fittings clean; ensure bleeder nipples are snug (don’t overtighten).
  • Install reservoir caps and diaphragms correctly to avoid leaks.
  • Check lever and pedal for firm operation at rest and during a short low-speed test ride in a safe area.
  • Inspect for leaks around calipers, lines, and master cylinders after the test ride and recheck fluid level.
  • Record the date and mileage of service in your maintenance log.

Troubleshooting

  • Persistent spongy pedal after repeated bleeds usually indicates trapped air, a soft/swollen hose, or a leaking master cylinder. Replace faulty components and repeat bleed.
  • If brake performance is still poor with no air present, inspect pads, rotors, and caliper pistons for contamination or damage.
  • If you encounter rusted or rounded bleeder nipples, address them carefully to avoid breakage — replace if necessary.

MotoSport maintenance tips for the Outlander 650 XT

  • Replace brake fluid every 1-2 years or sooner if it looks dark or contaminated. Moisture absorption reduces boiling point and braking performance.
  • Keep an eye on the rear master cylinder boot for tears; dirt ingress can damage seals on this model.
  • When fitting aftermarket parts, match fluid compatibility and hose fittings to avoid leaks and warranty issues.
  • Always use new fluid from a sealed container and avoid topping up with mixed or unknown fluids.

Following this MotoSport-exclusive procedure will help you safely replace brake fluid and remove air from your 2008 Can-Am Outlander 650 XT braking system. If you find major component failure or are uncomfortable performing any step, contact a qualified technician.
