This MotoSport guide walks you through a complete brake fluid change & bleed for the 2018 Can-Am Outlander 650 DPS. Work safely, use the correct fluid, and follow a methodical bleed sequence to restore firm, reliable braking.

Important model notes for the 2018 Can-Am Outlander 650 DPS

  • The Outlander 650 DPS uses hydraulic disc brakes and requires DOT 4 brake fluid. Do not mix DOT 3, DOT 4 & DOT 5/5.1 incompatibilitiesuse DOT 4 per Can-Am recommendations.
  • DPS stands for Dynamic Power Steering. Power steering components are separate from the brake system but are close physically; keep brake fluid away from painted surfaces and power steering parts.
  • ABS is not fitted to all Outlander 650 DPS models. If your machine has any factory-installed feedback sensors or aftermarket ABS components, consult the sensor service instructions before bleeding.
  • Brake caliper bleed nipple sizes can vary; common sizes are 8 mm or 10 mm. Have both metric flare wrenches ready and confirm exact sizes with parts from MotoSport if uncertain.

Tools & supplies

  • DOT 4 brake fluid (new, unopened)
  • Clear hose and catch bottle
  • Flare wrench set (8 mm & 10 mm commonly used)
  • Rubber gloves, safety glasses, rags
  • Jack or ramps and stands for safe wheel access
  • Brake cleaner and small brush
  • Optional: vacuum or pressure brake bleeder (10-15 psi recommended for pressure bleeding)

Safety & prep

  • Work on a level surface, engine off, parking brake engaged. If using pressure bleeder, follow manufacturer limits (10-15 psi).
  • Protect painted surfaces from brake fluid. Brake fluid will damage paint.
  • Keep the reservoir cap and master cylinder clean. Open reservoir only when ready to draw fluid into it.
  • Wear gloves and eye protection. Dispose of old fluid responsibly.

Step-by-step: Complete brake fluid replacement & bleed

1. Inspect system and top-up reservoir

  • Clean reservoir area. Remove cap and diaphragm. Note fluid color and level.
  • If fluid is dark or contaminated, proceed with a full flush.

2. Lift machine for safe wheel/caliper access

  • Support securely on stands so wheels are off the ground and calipers accessible.

3. Determine bleed order

  • Identify master cylinder location. Bleed the caliper farthest from the master cylinder first, then the next-farthest, working toward the nearest caliper. For 4-wheel ATVs that means start with the wheel opposite the master cylinder and finish with the wheel on the same side as the master.

4. Remove old fluid from reservoir

  • Use a syringe or turkey baster to remove as much old fluid from reservoir as possible without letting air enter the master cylinder feed. Refill with fresh DOT 4 so the reservoir stays between MIN and MAX throughout the job.

5. Bleeding methods (choose one)

  • Manual pump bleed
    1. Attach clear hose to bleed nipple, submerge other end in a bottle partially filled with fresh fluid to prevent air re-entry.
    2. Have an assistant pump the brake lever/pedal several times and hold it down.
    3. Open bleed nipple with flare wrench until fluid & air bubble exit; close before the assistant releases lever.
    4. Repeat until clear, bubble-free fluid appears and lever feels firm. Keep reservoir topped up.
  • Vacuum bleeder
    1. Attach vacuum pump to bleed nipple, open nipple, and draw fluid until clear. Close nipple before releasing vacuum. Move to next caliper.
  • Pressure bleeder
    1. Pressurize master cylinder reservoir per tool instructions (10-15 psi). Open each bleed nipple in sequence until clear fluid appears. Close nipple before moving on.

6. Flush each caliper until clear

  • Repeat bleeding process on each caliper in the prescribed order. Monitor reservoir level and top up frequently with fresh DOT 4.
  • If fluid darkly stained persists, continue bleeding until fluid runs clear and clean.

7. Final checks

  • Once all calipers are bled, confirm reservoir is at correct level and reinstall diaphragm and cap securely.
  • Pump brake lever/pedal with engine off to confirm firmness. If soft or spongy, repeat bleeding sequence or inspect for leaks.
  • Inspect bleed nipples, hoses, calipers, and lines for leaks with hand pressure applied.
  • Torque any wheel fasteners to Can-Am specifications and lower bike safely.

Troubleshooting & things to watch for

  • Persistent soft pedal: likely remaining air or a leak. Recheck hose fittings, caliper pistons, and master cylinder seals.
  • Contaminated fluid that does not clear: consider internal master cylinder or ABS unit contamination; professional service may be required.
  • Brake drag after bleeding: check caliper pistons for proper retraction and ensure bleeder nipples are fully closed.
  • Never mix brake fluid types. If DOT 5 (silicone) was mistakenly added, a complete system teardown and flush is required.

Maintenance interval recommendation

MotoSport recommends replacing brake fluid every 1-2 years depending on use and exposure to moisture. Aggressive riding or frequent wet conditions can shorten fluid life; change sooner if fluid darkens or performance degrades.

Final notes

Use OEM-quality parts and seals when replacing hoses or bleed screws. If you are uncomfortable with brake system work, have the Outlander serviced by a qualified technician. Keeping brake fluid fresh and properly bled preserves the DPS riding experience and ensures safe stopping performance.
