This MotoSport-exclusive guide covers step-by-step procedures, model-specific notes for the 2020 Can-Am Outlander MAX 450 DPS, required tools, and safety reminders to properly replace and bleed the brake fluid on your MMY ATV.
About the 2020 Can-Am Outlander MAX 450 DPS
- Factory brake system uses DOT 4 brake fluid; always use fresh DOT 4 meeting SAE J1703 specifications.
- MAX 450 DPS has a dual-seat, wide-track chassis and electronic DPS (Dynamic Power Steering) that may be sensitive to contamination — keep brake fluid and tools away from electrical connectors and the steering rack.
- Master cylinder/reservoir locations: front handlebar master cylinder for front brake and a separate rear reservoir or integrated system depending on production batch — inspect your machine to confirm reservoir positions before starting.
- Replacement intervals: brake fluid is hygroscopic; MotoSport recommends changing fluid every 1-2 years or sooner if discolored or subject to heavy use.
Tools & Supplies
- DOT 4 brake fluid (new, unopened)
- Brake bleeder kit or clear tubing and a collection bottle
- Wrench set (commonly 8mm-11mm for bleed screws — verify on your model)
- Brake cleaner, shop rags, and gloves
- Torque wrench for caliper hardware if reassembly required
- Optional: vacuum or pressure bleeder for faster, cleaner bleeding
Preparation
- Park ATV on level ground, engage parking brake, remove key, disconnect battery negative terminal if working near electricals.
- Clean around reservoir caps thoroughly to prevent contamination. Remove cap and diaphragm, cover reservoir to avoid debris. Note reservoir position so you know which lines feed which calipers.
- Inspect brake lines, hoses, calipers, and pads for wear or leaks. Replace any compromised components before bleeding.
Bleed Sequence Principle
Always bleed starting with the brake caliper furthest from the master cylinder, then proceed to the next furthest, ending with the caliper closest to the master cylinder. On many Outlander MAX layouts this typically is: rear passenger side – rear driver side – front passenger side – front driver side. Confirm on your machine which caliper is furthest from the reservoir before starting.
Step-by-Step Fluid Replacement & Bleeding
- Top off reservoir with fresh DOT 4 fluid. Keep cap loosely in place to limit contamination while allowing air escape.
- Attach clear tubing to the bleed nipple of the first caliper and submerge the other end in a bottle partially filled with fluid to prevent air re-entry.
- Have an assistant slowly depress the brake pedal/lever 3-4 times and hold it down. Open the bleed screw to allow fluid and air to escape; close screw before the pedal/lever is released. Repeat until clear, bubble-free fluid flows. Keep reservoir level above minimum the entire time to avoid introducing more air.
- After the circuit is clear, tighten bleed screw to manufacturer torque or snugly if torque spec is not available. Wipe any spilled fluid immediately with a rag and brake cleaner; DOT fluid damages paint and plastic.
- Move to the next caliper following the furthest-to-closest sequence. Refill reservoir as needed during the process.
- If using a vacuum or pressure bleeder, follow device instructions but maintain the same caliper sequence and keep reservoir topped off.
- When all calipers are bled, perform a final bleed of the closest caliper to the master cylinder to ensure no residual air remains.
- Pump the brake lever/pedal several times to confirm firm lever feel and proper pedal height. If spongy, repeat bleeding steps or inspect for leaks or remaining air.
Post-Bleed Checks
- Verify no leaks at bleed screws, banjo bolts, or hose fittings. Torque hardware to factory specs where specified.
- Clean up spilled fluid and reinstall reservoir diaphragm and cap securely.
- Reconnect battery negative if disconnected. Test brakes at low speed in a safe area before returning to regular riding.
- Dispose of used brake fluid responsibly according to local regulations.
Model-Specific Tips & Cautions for MMY Outlander MAX 450 DPS
- Keep brake fluid off DPS components and electrical connectors. If fluid contacts paint or plastics, rinse with water and clean immediately.
- If your MAX 450 shows inconsistent brake feel front to rear, verify split-circuit layout — some systems route brakes through a proportioning valve or secondary circuits. Don't assume both reservoirs feed all calipers.
- If replacing brake hoses or calipers, replace crush washers at banjo fittings and torque bolts to spec. Bleed thoroughly afterward.
- After extended storage or heavy duty use, inspect master cylinder seals and piston feel; a worn master cylinder can mimic air-in-system symptoms yet will require component service.
- Keep a spare 500-1000 mL of DOT 4 and a small bleed kit in your shop for routine maintenance; MotoSport parts listings carry model-specific hoses, calipers, and hardware if replacement is required.
Troubleshooting
- Persistent spongy feel: re-bleed, check for soft hoses, leaking seals, or master cylinder issues.
- No pressure after bleeding: inspect for leaks, collapsed lines, or internal master cylinder failure.
- Air returning during bleed: reservoir cap vent blocked or fluid level dropped below minimum; re-check and continue bleeding.
Summary
Replacing and bleeding brake fluid on a 2020 Can-Am Outlander MAX 450 DPS requires clean technique, the correct DOT 4 fluid, and bleeding from the furthest caliper toward the master cylinder. Protect DPS and electrical components from contamination, keep the reservoir topped off, and test brakes carefully after service. For shop-quality parts and model-specific replacements, MotoSport offers the components needed to keep your MAX 450 stopping safely.
