This MotoSport proprietary guide walks you through replacing and bleeding the brake fluid on a 2009 Can-Am Outlander MAX 400 (MMY OLM400 2009). Follow these steps carefully, use proper PPE, and perform the job on a level surface with the engine off and the key removed.

Tools & supplies

  • DOT 4 brake fluid (fresh, unopened)
  • Clear tubing to fit bleeder nipples
  • Catch bottle or jar with one-way valve or reservoir cap adapter
  • Brake bleeder wrench or 8 mm/10 mm box wrench (verify bleeder size)
  • Turkey baster or fluid syringe (to remove old fluid from master cylinder)
  • Clean rags, gloves, eye protection
  • Optional: vacuum/pressure bleeder
  • Service manual for bolt torque specs and bleed sequence reference

Safety & preparatory notes specific to the 2009 Outlander MAX 400

  • The Outlander MAX 400 uses DOT 4 fluid. Do not mix DOT 3 or silicone fluids with DOT 4.
  • This model has separate front and rear brake circuits. Work one circuit at a time to avoid contamination.
  • Brake fluid attacks paint and plastics. Protect bodywork and master cylinder paint with rags taped around openings.
  • If your machine has an ABS or hydraulic control unit, follow factory procedures. If unsure, consult MotoSport service or the Can-Am service manual before proceeding.
  • Bleed with the bike level and wheels on the ground (or chocked) so caliper pistons remain in their normal position.

Step 1 – Inspect, clean & prepare

  • Clean the master cylinder reservoir cap and surrounding area to prevent dirt entry.
  • Remove reservoir cap and diaphragm. Use a turkey baster to extract old fluid to lower the fluid level but do not let the reservoir run dry unless you are prepared to prime the system immediately.
  • Top with fresh DOT 4 fluid to the recommended level.
  • Identify bleeder screws on each caliper. Fit clear tubing over the nipple and route it into a catch bottle partially filled with clean brake fluid to prevent air re-entry.

Step 2 – Bleeding order & method

Common bleeding order for the Outlander MAX 400: farthest from master cylinder first, then closer. Typically:

  • Rear caliper (if twin rear calipers, do farthest wheel first)
  • Front calipers left or right as the last steps

Use one of these methods:

Manual two-person method

  • One person pumps the brake lever/pedal several times and holds pressure.
  • Second person cracks the bleeder screw until fluid runs with no bubbles, then retightens.
  • Repeat until clear, bubble-free fluid emerges. Refill reservoir frequently to avoid air entering the master cylinder.

Vacuum or pressure bleeder (recommended for a clean, fast job)

  • Attach vacuum hose to the bleeder nipple or attach pressure bleeder to the reservoir per unit instructions.
  • Open bleeder and draw/pressurize fluid until clear fluid flows without bubbles.

Step 3 – Finish each caliper

  • When clear fluid appears, close bleeder and torque to a snug setting. Avoid over-tightening; check service manual for exact torque.
  • Pump brake lever/pedal to build normal firmness. If the lever/pedal is spongy, repeat bleeding for that circuit.
  • Clean any spilled fluid immediately and replace the reservoir diaphragm and cap.

Step 4 – Replace all fluid & final checks

  • Continue bleeding until the fluid in the reservoir is fresh and clear and all air is removed from every circuit.
  • Top reservoir to specification, reinstall cap, and wipe down components.
  • Test brakes at low speed in a safe area to confirm firm, consistent braking before normal use.

Maintenance intervals & owner tips

  • Replace brake fluid every 1–2 years or sooner if contaminated, especially if you ride in wet or humid conditions.
  • Check for leaks at banjo bolts, caliper seals, and hose fittings after the first test ride following service.
  • If you encounter persistent soft pedal or fluid loss, suspect a leak, worn caliper seals, or master cylinder issues — inspect and replace components as needed.
  • Keep an OEM or high-quality replacement master cylinder diaphragm on hand when servicing; the rubber ages and can tear when removed.

Troubleshooting

  • Persistent bubbles after thorough bleeding – inspect hoses for internal degradation or sponginess and replace lines if necessary.
  • Brake lever/pedal pulls to the handlebar with no visible leaks – check caliper pistons for corrosion or sticking; rebuild calipers if needed.
  • Fluid turns dark quickly – indicates contamination or moisture ingress; ensure reservoir cap seals correctly and replace fluid more often.

When in doubt, consult MotoSport service specialists or reference the factory service manual for torque specs and ABS-specific procedures unique to the 2009 Can-Am Outlander MAX 400. Properly bled brakes are critical for safe riding — don't rush the job.
