This MotoSport-exclusive service guide walks you step-by-step through flushing and bleeding the hydraulic brake system on a 2015 Can-Am Outlander MAX 650 XT (OLM650XT). Follow these instructions precisely to maintain braking performance and safety. If you are not comfortable with brake systems, consult a certified technician.

What you need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear vinyl tubing sized to bleed nipple
  • Catch bottle or jar
  • Brake bleeder wrench or appropriate open-end wrench
  • Turkey baster or fluid syringe (optional)
  • Clean rags and disposable gloves
  • Torque wrench for caliper/clamp bolts
  • Jack or ramps and stands to lift rear of machine safely
  • Shop light

Model notes — what MMY owners should know

  • The Outlander MAX 650 XT uses a hydraulic front and rear brake system with separate calipers; the rear brake has an integrated parking brake mechanism on twin-seat variants. Take care not to damage the parking brake components when accessing the rear caliper.
  • Master cylinder reservoirs are small and located near the handlebar (front) and near the rear brake assembly (rear). The reservoirs have rubber diaphragms that must be seated properly after service to prevent contamination and air ingress.
  • DOT 4 is factory-specified; do not mix with DOT 5 silicone. If you encounter brown or black fluid, replace it completely — contamination reduces boiling point & braking efficiency.
  • ABS is not present on this model, so bleeding sequences are conventional, but keep the brake lever/pedal depressed when opening bleed nipples to avoid introducing air.

Safety first

  • Work on a level, stable surface with the engine off and key removed.
  • Wear eye protection and gloves. Brake fluid is corrosive to paint & plastics.
  • Keep a fire extinguisher nearby when working with flammable liquids.

Preparation

  1. Park machine on level ground. Lift the rear with stands or ramps so wheels rotate freely where applicable. Chock wheels if necessary.
  2. Clean the master cylinder reservoir caps and surrounding area to prevent dirt entering the system.
  3. Remove reservoir caps and rubber diaphragms. Use a turkey baster to remove most old fluid from each reservoir to minimize overflow when pumping.
  4. Top reservoirs with fresh DOT 4 fluid to the specified level. Keep reservoirs capped loosely to limit contamination but allow air escape during bleeding.

Bleeding order

For the Outlander MAX 650 XT use this sequence: farthest caliper from the master cylinder first, then the nearest. For the front system that typically means right front then left front. For the rear, bleed the wheel farthest from the rear master cylinder, then the nearest. If unsure, start with the caliper that appears hardest to access.

Bleeding procedure — single-operator (squeeze & hold method)

  1. Attach clear vinyl tubing to the bleed nipple of the caliper being bled. Route the tubing into the catch bottle partially filled with clean brake fluid to prevent air being sucked back in.
  2. Open the bleed nipple about 1/4 turn with the wrench. Have an assistant slowly depress the brake lever or pedal and hold it at the firm point.
  3. With lever held, tighten the bleed nipple. Instruct assistant to release the lever slowly. Repeat until clear, bubble-free fluid flows and no air appears in the tubing. Keep reservoir topped with fresh fluid during process.
  4. Once clear, tighten bleed nipple to specified snugness. Wipe area, cap nipple if applicable, then move to the next caliper following the bleed order.
  5. After bleeding all calipers, top each reservoir to its mark, reinstall diaphragms and caps, and test lever/pedal firmness. If lever feels spongy, repeat bleeding process.

Alternative — vacuum or pressure bleeder

Using a vacuum pump on each bleed nipple or a pressure bleeder on the reservoir speeds the job and is effective at removing stubborn air. If using a pressure bleeder, keep reservoir pressure within manufacturer-recommended limits and monitor fluid level carefully.

Final checks

  • Confirm all bleed nipples are torqued to specification and free of leaks.
  • Check brake lever travel and pedal firmness at multiple points. A firm pedal or lever with consistent travel indicates successful bleeding.
  • Inspect brake lines, hoses, and calipers for wear, cracks, or fluid seepage. Replace any components showing damage.
  • Road test at low speed in a safe area to verify braking performance before returning to normal riding.

Maintenance tips from MotoSport

  • Brake fluid should be replaced every 1-2 years depending on use & environment. Heavy trail use or frequent wet conditions justifies annual replacement.
  • Store DOT 4 in its original container and use within manufacturer shelf life to ensure performance.
  • Keep a small service kit with spare diaphragms, bleed nipple caps, and a fresh bottle of DOT 4 for field maintenance.
