How to bleed and replace brake fluid on a 2021 Can-Am Outlander MAX 570

This MotoSport-exclusive guide walks you through a complete brake fluid change and bleed on a 2021 Can-Am Outlander MAX 570 (OLM570). Follow these steps closely for safe, reliable braking performance. Use DOT 4 brake fluid only and work in a clean, well-ventilated area. Brake fluid is hygroscopic & corrosive — protect painted surfaces and rubber components.

What you need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear tubing that fits bleed nipples
  • Catch bottle marked for used brake fluid
  • Wrench set for bleed nipples and caliper hardware
  • Vacuum or pressure bleeder (recommended) or a helper
  • Clean rags and brake cleaner
  • Gloves and eye protection
  • Shop manual or service torque specs (recommended)
  • Jack and stands or ramps to access calipers

Notes specific to the 2021 Can-Am Outlander MAX 570

  • The OLM570 uses a combined brake system with separate front and rear calipers. Brake reservoir is under a seat/panel access cover; remove the seat and the small access panel to reach the master cylinder reservoir.
  • There is no factory ABS on the base 570 MAX models, but some editions may have optional chassis features; confirm your configuration before working.
  • Use only DOT 4; never mix with DOT 3 or DOT 5 silicone fluid. Mixing fluids can damage seals and lead to failure.
  • If your ATV has a tandem master cylinder or proportioning valve, be cautious when opening lines — bleed the system as described in the manual (master cylinder to calipers sequence).
  • Keep the reservoir cap and diaphragm clean and replace the diaphragm if brittle or cracked.

Preparation

  1. Park on level ground, engage park brake, and remove key.
  2. Remove seat and access cover to expose the brake fluid reservoir. Clean the area around the cap to avoid contamination.
  3. Use jack/stands or ramps to raise the wheels off the ground so you can access all bleed nipples easily.
  4. Inspect calipers, lines, and hoses for damage or leaks. Replace any brittle hoses or corroded fittings before bleeding.
  5. Open the reservoir and clean the inside of the cap. Remove old fluid from the reservoir using a turkey baster or suction tool until level is near minimum to avoid overflowing when pumping.

Bleeding & Fluid Replacement recommended sequence

On most Outlander MAX 570 setups bleed the farthest caliper from the master cylinder first, then the next farthest, finishing with the closest. Typically that sequence is: rear passenger, rear driver, front passenger, front driver. Confirm with your specific layout before starting. Maintain reservoir fluid level above the minimum during the entire procedure.

Method A Pressure bleeder (recommended for one-person, cleaner)

  1. Attach the pressure bleeder to the reservoir per tool instructions and pressurize to the tool's recommended setting.
  2. Place clear tubing over the bleed nipple of the furthest caliper and submerge the other end in a catch bottle partially filled with fresh fluid to avoid introducing air.
  3. Open the bleed nipple 1/4 to 1/2 turn until old fluid and air stop flowing, then tighten. Close fully before moving to the next caliper.
  4. Repeat for each caliper in the proper sequence. Top reservoir with fresh DOT 4 fluid as needed to avoid drawing air.
  5. After completing all calipers, cycle the brake lever/pedal several times to confirm a firm feel. Re-check nipples for leaks and torque caliper hardware per service manual.

Method B Manual pump & one-way valve (with helper)

  1. Fit a one-way bleed valve or have a helper pump the brake lever/pedal and hold pressure.
  2. With the lever held, open the bleed nipple of the farthest caliper until fluid runs clear and free of bubbles, then close the nipple before the helper releases the lever.
  3. Repeat this open-close pump-and-hold cycle until no air appears. Move to the next caliper and repeat the sequence.
  4. Always keep reservoir topped up with fresh DOT 4 fluid to prevent air entry.

Finishing steps

  • Clean all nipples and fittings with brake cleaner and wipe dry. Make sure bleed nipples are tightened securely but do not over-torque; consult the service manual for specific torque values.
  • Refill reservoir to the MAX mark, reinstall the diaphragm and cap, and reinstall any removed panels or the seat.
  • Operate the brake lever/pedal several times to verify a firm, consistent feel. Test brakes at low speed in a safe area before returning to regular use.
  • Dispose of used brake fluid properly — it must not be poured on the ground or into drains.

Troubleshooting & inspection items

  • Spongy lever/pedal after bleeding usually means air remains in the system; repeat bleeding sequence and ensure reservoir never runs low.
  • Persistent soft brake feel may indicate worn pads, internal master cylinder leaks, or a faulty caliper piston — inspect and replace parts as needed.
  • Corroded fittings or swollen hoses should be replaced. Replace the master cylinder diaphragm if hardened or damaged.
  • After long-term storage check seals & hoses for shrinking or cracking before use.

MotoSport maintenance tips for your OLM570

  • Bleed and replace brake fluid every 1-2 years depending on use and moisture exposure; frequent wet or muddy riding may require yearly service.
  • Keep a spare reservoir diaphragm & cap seal on hand during bleeding jobs in case the OEM components have deteriorated.
  • If you perform a full brake overhaul, replace pads and inspect rotors for scoring; use OEM-spec or MotoSport-approved replacement parts for correct fit and safety.
  • Document fluid changes and brake service dates in your maintenance log to preserve resale value and ensure reliable performance.

When in doubt, consult the official service manual for disassembly, torque specs, and model-specific diagrams. If you prefer parts, tools, or OEM-quality replacements, visit our MotoSport parts page for the 2021 Can-Am Outlander MAX 570.
