This MotoSport guide walks you through safely flushing and replacing the brake fluid on a 2019 Can-Am Outlander MAX 450 DPS (MMY OLM450DPS). Follow each step carefully. If you're not comfortable with brake-system service, contact a qualified technician.
Model notes specific to the 2019 Outlander MAX 450 DPS
- Brake fluid specification: use DOT 4 brake fluid only. Do not mix with DOT 5 (silicone).
- Master cylinders: the front brake master cylinder is on the right handlebar; the rear brake uses its own master cylinder actuated by the foot pedal. Each circuit is bled separately.
- Brake layout: bleed the caliper farthest from its master cylinder first, then work toward the closest. On this model that typically means: front opposite-side first (farthest from handlebar master cylinder), then front closest; for the rear circuit, bleed the caliper farthest from the rear master cylinder first.
- ABS/CBC: this model does not have ABS on early 450 DPS variants. If your machine has additional electronic brake control, follow manufacturer procedures for cycling.
Tools & materials
- DOT 4 brake fluid (new, in sealed container)
- Clear plastic tubing to fit bleed nipples
- Brake bleed catch bottle or clear jar
- Wrench or socket to open bleed nipples (typically 8mm or 10mmverify on your unit)
- Assistant or a one-person vacuum/pressure bleeder
- Clean shop rags, gloves, eye protection
- Torque wrench for reassembly (if replacing components)
- Hand cleaner and brake-safe parts cleaner
Preparation
- Park on level ground, set parking brake, and remove key. Chock wheels for safety.
- Clean around each brake fluid reservoir cap before opening to avoid contamination.
- Remove reservoir caps and diaphragms. Keep reservoirs topped with fresh DOT 4 fluid during the procedure to prevent air entry.
- Locate each caliper bleed nipple and confirm wrench size. Inspect hoses and lines for damage before starting.
Bleeding sequence & general approach
Bleed each circuit separately: front circuit (handlebar master cylinder) and rear circuit (foot pedal master cylinder). For each circuit, follow this order: farthest caliper from its master cylinder first, then progressively closer. Always keep the reservoir at least half full during bleeding.
Step-by-step: Traditional two-person manual bleed
- Have one person sit on the machine to operate the brake lever or pedal while the other works at the bleed nipple.
- Attach clear tubing to the caliper bleed nipple and route the other end into a catch bottle partially filled with fresh brake fluid. Submerge the tube end slightly so no air can be drawn back into the line.
- Loosen the bleed nipple about a quarter turn. Do not remove it.
- Assistant squeezes the brake lever/pedal slowly to the fully applied position and holds it down. The operator opens the bleed nipple briefly to allow fluid and air to escape into the tube, then closes the nipple before the lever/pedal is released. Repeat until fluid runs clear, bubble-free, from the tube.
- After finishing a caliper, tighten the bleed nipple to spec snug (do not over-torque) and wipe any spilled fluid immediately.
- Move to the next caliper in the sequence and repeat. For the rear circuit, follow the farthest-to-closest rule relative to the rear master cylinder.
- Top off reservoirs to the correct level after completing each circuit and replace diaphragms and caps.
- After bleeding both circuits, pump each brake lever/pedal several times to confirm firm feel. If sponginess remains, repeat bleeding until firm.
Step-by-step: One-person vacuum or pressure bleeder (preferred for convenience)
- Connect the vacuum pump to the caliper bleed nipple hose or attach a pressure bleeder to the master cylinder reservoir per the bleeder manufacturer's instructions.
- If using a vacuum on the caliper, open the bleed nipple and draw fluid until it runs clear and bubble-free, then close the nipple while vacuum is applied. If using a pressure bleeder on the reservoir, pressurize the reservoir and open each bleed nipple in sequence until fluid is clear.
- Follow the same farthest-to-closest sequence for each circuit.
- Top off reservoirs, relieve pressure on the bleeder tool per instructions, then tighten nipples and clean up.
Flushing vs. topping off
To fully replace old fluid, repeatedly draw new fluid through until the fluid in the catch bottle is fresh and clear and the master reservoir contains only new fluid. For a full flush, suction old fluid from the reservoir first, then refill with new DOT 4 before bleeding. Do not reuse drained fluid.
Finish, inspection & testing
- Ensure all bleed nipples and reservoir caps are properly tightened and secured. Clean any spilled fluid from painted or plastic surfaces; brake fluid damages paint and plastics.
- Check brake lever and pedal travel for firmness with the engine off, then start and confirm consistent braking under low-speed test conditions in a safe area.
- Re-check fluid levels after a short test ride and again after a day of use. Re-inspect lines and fittings for leaks.
- Dispose of used brake fluid responsibly per local regulations.
Common issues & troubleshooting
- Persistent spongy lever/pedal: likely air remains in the system; repeat bleeding and ensure reservoir never runs low during procedure.
- Brake lever/pedal sinks slowly under pressure: inspect master cylinder seals and caliper pistons for internal leaksrepair or replace as needed.
- Fluid contamination or dark fluid: complete flush required; inspect lines and calipers for deterioration.
Safety reminders
- Brake fluid is corrosive to paint and plasticsclean spills immediately.
- Use only DOT 4 brake fluid. Keep fluid containers sealed and use fresh fluid.
- If you detect internal leaks, damaged hoses, or questionable components, replace them. Brakes are safety-critical.
Performing a proper brake fluid replacement and bleed on your 2019 Can-Am Outlander MAX 450 DPS restores braking feel and reliability. When in doubt, consult a trained ATV technician or MotoSport service professional for hands-on assistance.
