This guide is MotoSport's proprietary procedure for replacing and bleeding the hydraulic brake system on a 2011 Can-Am Outlander 650. It covers safety, tools, fluid selection, step-by-step bleeding methods, tips specific to the MMY ATV, and post-service checks. Follow all safety steps and wear eye protection and gloves. If your Outlander is equipped with factory ABS, read the model notes below before proceeding.

Tools & materials

  • DOT 4 brake fluid (use fresh, high-quality DOT 4; Do not mix with DOT 5 silicone)
  • Clear hose that fits bleeder nipples snugly
  • Brake bleeder bottle or catch container
  • 10 mm wrench for bleeder screws (verify size before starting)
  • Flat screwdriver or pliers to open reservoir cap clips
  • Clean shop rags and parts cleaner
  • Assistant (recommended) or a pressure/vacuum bleeder
  • Torque wrench for caliper fasteners if removed
  • Funnel and clean bottle for fresh fluid

Model-specific notes for the 2011 Can-Am Outlander 650

  • The Outlander 650 uses a DOT 4 hydraulic system. Use DOT 4 only unless the owner manual specifies otherwise.
  • Master cylinder reservoir is located on the handlebar area for the front brake and near the rear master cylinder for the rear brake (depending on trim). Verify which reservoir feeds which circuit before starting.
  • Some 2011 Outlander models may have optional ABS or combined braking features. If your unit has ABS, do not open or disturb the ABS module plumbing; follow manufacturer ABS bleeding procedure or have a dealer perform ABS-related bleeding.
  • Brake line routing and caliper locations are compact – protect hoses from kinking when positioning the ATV on a rack.
  • Replace rubber parts that show swelling, cracking, or deterioration &mdash caliper seals and hoses age quicker in off-road use.

Preparation

  1. Park on level ground, engage park gear and block wheels. Remove key and disconnect battery negative if you will be working near electrical components.
  2. Clean around each brake reservoir cap to prevent contamination. Remove caps carefully; keep diaphragms and caps clean.
  3. Inspect calipers, hoses, and fittings for leaks or damage. Replace damaged components before bleeding.
  4. Fill the reservoir(s) to the maximum mark with fresh DOT 4 fluid and keep a small shop towel under the cap to catch drips.

Bleeding order principle

Always start bleeding at the caliper farthest from the master cylinder and finish nearest to it. For most Outlander layouts that means: rear caliper first (if rear master cylinder is separate check which reservoir feeds which circuit), then one front caliper, then the other front caliper, ending at the caliper nearest the master cylinder. Verify actual hose routing on your machine before starting.

Manual two-person bleed method

  1. Have assistant sit on the seat and slowly apply steady brake pressure when requested; do not ride the brakes.
  2. Attach clear hose to the bleeder nipple and place the other end into a catch bottle partly filled with fresh fluid to avoid drawing air back in.
  3. Open the bleeder screw about one-quarter to one-half turn. The assistant applies steady pressure on the lever/pedal until you see just fluid (and bubbles, initially) exit the hose. Close the bleeder while pressure is applied to avoid sucking air back in.
  4. Release brake slowly and repeat until no air bubbles appear and fluid runs clear. Keep reservoir topped up during the process to avoid introducing air into the master cylinder.
  5. Move to the next caliper in the bleeding order and repeat. Final bleed should be the caliper closest to the master cylinder.
  6. After final caliper, pump lever/pedal with engine off to confirm firm feel. If spongy, repeat bleeding sequence.
  7. Tighten bleeder screws to snug. Wipe all surfaces and reinstall reservoir caps securely. Dispose of used fluid properly.

Single-person vacuum or pressure bleeder method

  • Connect vacuum bleeder to bleeder nipple or use a pressure bleeder on the reservoir per tool instructions.
  • Maintain reservoir level while pulling fluid through each caliper in the correct order.
  • Vacuum and pressure bleeders reduce effort and limit air entry. Still confirm no bubbles at the end and test lever/pedal firmness.

Bench bleeding the master cylinder (if replaced)

  • If you replace the master cylinder, bench-bleed it before installation using the manufacturer procedure &ndash usually by cycling fluid through small bleed fittings until no air remains.
  • Install and then bleed the system at the calipers in the standard order.

Inspection & final checks

  1. Verify reservoir fluid level at the proper mark after bleeding. Clean any spilled fluid from paint and plastic immediately &mdash brake fluid can damage finishes.
  2. Check for leaks at bleeder screws, calipers, hose fittings, and master cylinder. Tighten fittings to proper fitment; do not overtighten plastic reservoirs or strip threads.
  3. With engine off, confirm lever/pedal is firm and does not creep. With parking brake released, test stopping performance at low speed in a safe open area.
  4. Road-test gradually under light conditions to confirm consistent braking feel. Recheck fluid level after first short ride and inspect for leaks.
  5. Record fluid change in maintenance log. For off-road or heavy-use conditions, inspect brakes more frequently and replace fluid every 1–2 years or per severe-use schedule.

Troubleshooting common issues

  • Persistent spongy brake feel after thorough bleeding may indicate a reservoir leak, collapsed hose, contaminated fluid, or internal master cylinder failure &mdash inspect and replace parts as needed.
  • Air that returns after only a short ride usually means the reservoir ran low during bleeding or a leak is present.
  • If ABS-related warnings or unusual behavior occur after bleeding, stop and consult a dealer or technician familiar with Can-Am ABS systems.

Safety & disposal

  • Brake fluid is hygroscopic and corrosive to paint & plastics. Avoid skin contact and dispose of used fluid at an approved recycling or hazardous waste facility.
  • Never reuse old brake fluid. Always keep the reservoir sealed and clean while servicing.
