Overview

This MotoSport guide covers draining, flushing, and bleeding the hydraulic brake system on a 2021 Can-Am Outlander MAX 570 DPS. It is written for the MMY Outlander MAX 570 DPS owner who wants a reliable, safe brake-fluid service and includes model-specific notes you should know before starting.

What you need

  • DOT 4 brake fluid (Can-Am-spec recommended)
  • Clear 3/16" or 1/4" tubing and a catch bottle
  • Wrench for bleeder nipples (typically 8 or 10 mm)
  • Vacuum bleeder or two-person helper
  • Clean rags, safety glasses, gloves
  • Brake cleaner, funnel, shop rags, torque wrench (if removing calipers)
  • Floor jack or ATV lift and stands

Model-specific notes for the 2021 Outlander MAX 570 DPS

  • The Outlander MAX 570 DPS uses sealed hydraulic discs front and rear. The master cylinder reservoir is accessible under the front center panel/seat area – clean around the cap before opening to avoid contamination.
  • DPS (Dynamic Power Steering) is an electrical/hydraulic assist system unrelated to the braking hydraulics, but avoid applying heavy steering force while wheels are off the ground during the procedure.
  • There is no factory ABS on this model; bleeding is traditional open hydraulic system style.
  • Use DOT 4 only unless the owner's manual explicitly states otherwise. Mixing fluids is unsafe.
  • Replace reservoir cap sealing gasket if damaged and keep reservoir fluid above the low mark throughout the job to prevent air re-entry.

Preparation

  1. Park on level ground, engage park/parking brake, remove key, and disconnect the negative battery terminal if you will be working near electrical connectors.
  2. Lift the ATV so all wheels are off the ground and secure with stands. Support is critical to avoid accidental movement.
  3. Clean the reservoir and surrounding area. Remove cap and diaphragm; cover the opening with clean shop towel if you pause to avoid contamination.
  4. Inspect brake lines, hoses, and calipers for leaks or damage. Replace any worn components before bleeding.

Bleed sequence principle

Always bleed from the caliper farthest from the master cylinder to the nearest. On the Outlander MAX 570, that means: rear far side (farthest), rear near side, front far side, front near side. If uncertain, use the “farthest to nearest” rule relative to the reservoir location.

Step-by-step bleeding & fluid replace

  1. Fill the reservoir with fresh DOT 4 fluid to the max mark. Keep a clean funnel or pour carefully to avoid spills; brake fluid damages paint.
  2. Attach clear tubing to the bleeder nipple on the first caliper and submerge the other end in a catch bottle partially filled with clean fluid to prevent air from being drawn back in.
  3. If using a helper: have helper slowly pump the brake lever/pedal several times and hold firm. Open the bleeder nipple about a quarter turn to allow fluid and air to escape until fluid runs clear and bubble-free, then close the nipple before the helper releases pressure. Repeat until no air appears. Keep reservoir topped up throughout.
  4. If using a vacuum/pressure bleeder: follow the device instructions. Apply vacuum at the bleeder or pressure to the reservoir as specified and cycle until clear fluid and no air bubbles appear at that caliper.
  5. Proceed to the next caliper in the pre-determined sequence, repeating tubing/catch setup and bleeding steps for each caliper.
  6. When all calipers are clear, perform a final bleed pass on the caliper nearest the master cylinder to ensure no air remains in the lines.
  7. After final bleed, tighten bleeder nipples to spec snugness (snug – don't over-torque), wipe all connections, and ensure reservoir is at the proper fluid level. Reinstall diaphragm and cap.
  8. Lower the ATV, reconnect battery if disconnected, and test brake lever/pedal firmness with the engine off. Expect firm, non-spongy feel. If soft, repeat bleeding steps.

Flushing recommendation

If you are replacing old fluid, flush by drawing fresh DOT 4 through the system until the reservoir and bleed-out are clear and free of dark contamination. Replace all fluid in the reservoir at least once; ideally flush until three reservoir refills produce clean fluid.

Post-service checks

  • Inspect for leaks at calipers, lines, and master cylinder after a short test ride.
  • Verify parking brake operation and that wheel rotation is smooth.
  • Dispose of old brake fluid properly — never reuse or mix with other waste.

Troubleshooting

  • Persistent spongy lever/pedal: likely remaining air or contaminated master cylinder internal seal — repeat bleeding or inspect master cylinder.
  • Leaking bleeder nipple: replace nipple or caliper hardware if threads or seats are damaged.
  • Brake fade after bleeding: check fluid grade and contamination, and ensure caliper pistons move freely.

Final notes

This MotoSport procedure is intended for competent DIY mechanics. If you find damaged components, extensive air in the system, or uncertain results, have the Outlander inspected and serviced by a qualified technician. Regular brake-fluid replacement keeps braking performance reliable and extends the life of brake components on your 2021 Can-Am Outlander MAX 570 DPS.
