This MotoSport how-to covers step-by-step service for bleeding the brake system and replacing brake fluid on a 2013 Can-Am Outlander MAX 400 (MMY OLM400). It is written for home mechanics with basic tools. Read each step fully before starting and follow the safety notes.

Safety & preparatory notes

  • Work on a level surface, park the machine in gear or use the parking brake, and disconnect the negative battery terminal if you will be working near electrical components.
  • Brake fluid is corrosive to paint and plastics. Keep rags ready and wash spills with water immediately.
  • MotoSport recommends using the factory-specified brake fluid. Can-Am Outlander 400 models commonly use DOT 4; confirm on the reservoir cap or owner’s manual before filling.
  • Wear nitrile gloves and eye protection. Keep a fire extinguisher nearby when working with fluids.
  • Properly dispose of old brake fluid at a recycling center; do not pour down drains.

Tools & supplies

  • Brake fluid (new, sealed DOT 4 unless manual specifies otherwise)
  • Wrench set (open-end or flare nut wrenches for bleeder valves; common sizes 8mm or 10mm)
  • Clear plastic tubing to fit bleeder nipples
  • Catch bottle for old fluid
  • Vacuum bleeder or squeeze-bulb or second-person for manual bleeding
  • Clean shop rags, gloves, and isopropyl alcohol for cleaning
  • Floor jack or ramps and jack stands if wheel removal is needed

Model-specific notes for the 2013 Can-Am Outlander MAX 400 (MMY OLM400)

  • The Outlander MAX 400 typically has a combined hydraulic system with a front master cylinder and a rear circuit routed through a proportioning block. Identify the master cylinder by locating the larger reservoir behind the handlebars (front) and the rear circuit reservoir or remote feed, if present.
  • Some 2013 Outlander MAX 400 machines have two calipers up front and one rear caliper; check your machine’s caliper count before deciding sequence. If in doubt, follow the standard rule: bleed the wheel farthest from the master cylinder first and finish with the nearest.
  • ABS is not fitted on most Outlander 400 models of this year; if your machine has any electronic brake components, consult the service manual before performing fluid replacement.

Step-by-step procedure

  1. Inspect system: Check reservoir level, hoses, fittings and bleeder screws for damage or leaks. Tighten any loose fittings before bleeding.
  2. Clean reservoir area: Wipe the cap and surrounding area with a clean rag and isopropyl alcohol to avoid contamination when opening.
  3. Top up with fresh fluid: Remove the reservoir cap and diaphragm. Add fresh DOT 4 brake fluid to the full mark. Do not let dirt or moisture enter the reservoir.
  4. Identify bleed order: Determine the master cylinder location. As a general rule, bleed the wheel farthest from the master cylinder first, then work closer. For many Outlander MAX 400 layouts this will be: rear wheel (if single rear caliper) first, then passenger-side front, then driver-side front, but confirm on your machine by identifying the line routing.
  5. Attach hose & catch bottle: Put a clear hose on the bleeder nipple and route to a bottle partially filled with clean brake fluid to prevent air re-entry. Keep the reservoir cap loosely on top to avoid overfilling contamination as you work.
  6. Bleeding method — manual (two-person): One person sits on the seat and slowly applies firm brake pressure then holds. The second person opens the bleeder screw about 1/4 to 1/2 turn until fluid runs out and then closes the screw. Repeat pump-hold-open-close until no air bubbles appear in the tubing. Top up the reservoir frequently to avoid running dry.
  7. Bleeding method — vacuum or pressure: Attach a vacuum bleeder to the bleeder nipple or use a pressure bleeder on the reservoir per the tool instructions. Pump fluid until clear, bubble-free fluid flows. Monitor reservoir level and keep it above minimum during the entire process.
  8. Repeat for each caliper: After finishing the farthest wheel, move to the next-farthest and repeat the same process. Always keep the reservoir topped up. Finish with the caliper nearest the master cylinder.
  9. Final check: When all wheels are bled, ensure the reservoir is at the full line and reinstall the diaphragm and cap. Pump the brake lever with the engine off until it feels firm. Start the engine and recheck firm pedal feel under load — it should not sink or feel spongy.
  10. Inspect for leaks: Cycle the brakes several times and inspect bleeder valves, hoses and caliper fittings under pressure. Tighten bleeders to the manufacturer-specified snugness; avoid over-torquing which can strip threads.
  11. Road test: Conduct a low-speed test ride in a safe area to confirm pedal response and braking performance. Re-inspect the system after the test for leaks and correct fluid level if needed.

Troubleshooting & tips

  • Spongy brake pedal after bleeding usually means air remains in the system or the reservoir ran dry during the process. Re-bleed, ensuring the reservoir never goes below the minimum mark.
  • If you cannot get a firm pedal, inspect caliper seals, master cylinder condition, and flexible hoses for swelling or internal collapse. Replace any suspect components.
  • Use clear tubing when bleeding so you can see bubbles. A vacuum bleeder speeds the job and reduces the chance of running the reservoir dry.
  • Label the reservoir with the fluid type if replacing after-market caps to prevent future mistakes during top-ups.

Maintenance interval recommendation

MotoSport recommends replacing brake fluid every two years or sooner if you ride in wet, high-humidity, or hard-use conditions. Regular fluid changes protect internal components from corrosion and maintain braking performance.

Parts & consumables

Replace bleeder screw crush washers if the system uses them and consider new caliper seals or hoses if the machine is original and old. Use fresh, sealed DOT 4 fluid and quality replacement parts for safety and longevity.
