This MotoSport.com guide walks you step-by-step through replacing and bleeding the brake fluid on a 2020 Can-Am Outlander MAX 450 6x6 DPS. Follow these procedures carefully for safe, reliable braking. Read fully before starting and gather tools, replacement fluid, and safety gear.

What you need

  • DOT 4 brake fluid (use fresh, unopened bottle)
  • Brake bleeder kit or clear tubing and a catch bottle
  • Wrench set (bleeder nipple size typically 8mm or 10mm; check nipple on your calipers)
  • Turkey baster or fluid syringe (optional for reservoir draining)
  • Clean rags, gloves, safety glasses
  • Torque wrench for caliper bolts if removed
  • Service manual or shop manual for torque specs & reservoir capacity reference

Safety first

  • Work on a level surface with the parking brake engaged and the engine off.
  • Avoid getting brake fluid on paint or plastic – it damages finishes. Protect surfaces with rags.
  • Keep fluid bottle sealed and dispose of old fluid responsibly per local regulations.

Model notes specific to the 2020 Outlander MAX 450 6x6 DPS

  • The Outlander MAX 450 6x6 DPS has a combined brake system with front and rear calipers tailored for the 6x6 chassis; routing and reservoir location mirror single-seat Outlander models but check both front and rear lines for fittings and bleeder nipple access.
  • DPS (Dynamic Power Steering) does not share fluid with brakes, but verify steering components are clear of spills during the service.
  • Master cylinder/reservoir location and mounting are accessible from the right-side footwell area; dust/debris can collect so clean around the cap before opening.
  • Use DOT 4 only unless your owner's manual specifies otherwise. DOT ratings matter for boiling point and compatibility.
  • If your ATV has aftermarket racks or skid plates, remover or loosen them for full access to calipers and bleeder screws.

Step 1 – Prepare the vehicle

  • Park on level ground, set transmission to park or neutral with wheels chocked.
  • Remove seat or paneling if needed to access the reservoir and lines comfortably.
  • Clean around the reservoir cap to prevent contamination.

Step 2 – Inspect condition

  • Check fluid color in the reservoir – dark or contaminated fluid indicates replacement necessary.
  • Inspect hoses, lines, and calipers for leaks, cracks, or swollen hoses. Address leaks before bleeding.

Step 3 – Remove old fluid from reservoir

  • Use a turkey baster or syringe to remove most old fluid from the reservoir. Don't empty completely if the system requires some fluid to prevent air intake; remove enough to start with clean fluid.
  • Top with fresh DOT 4 brake fluid until at the full mark.

Step 4 – Bleeding sequence

Use the recommended sequence: start with the caliper farthest from the master cylinder and move to the nearest. For the Outlander MAX 6x6, that typically means: rear passenger-side, rear driver-side, front passenger-side, front driver-side. Confirm positions visually & adjust if your bike's plumbing differs.

  • Attach clear tubing to the bleeder nipple and place the other end into a catch bottle partially filled with clean brake fluid to prevent air being drawn back in.
  • Have an assistant slowly pump the brake lever/pedal several times and hold pressure.
  • Open the bleeder screw 1/4 to 1/2 turn to allow fluid and air to escape. Close the screw before the assistant releases the lever/pedal. Repeat until fluid runs clear and bubble-free.
  • Continuously monitor the reservoir level – never let it drop below minimum or air will enter the ABS/modulator and require extra steps to purge.
  • Repeat the process for each caliper in the sequence until all lines clear.

Step 5 – Secondary flushing method (recommended for full replacement)

  • For a complete fluid change, perform multiple reservoir fills & bleeds until the reservoir fluid appears clear and the catch bottle shows fresh fluid.
  • Alternatively, use a pressurized brake bleeder or vacuum bleeder to speed the process, following the tool manufacturer's instructions.

Step 6 – Final checks

  • Top the reservoir to the full mark and securely replace the cap.
  • Tap and cycle the brake lever/pedal several times to confirm a firm feel. If the lever is spongy, repeat bleeding until firm.
  • Check bleeder screws for proper torque and ensure there are no leaks at calipers, master cylinder, or hose fittings.
  • Test ride slowly in a safe area to confirm braking performance before regular use.

Troubleshooting & tips

  • If air persists, consider bench-bleeding the master cylinder or using a pressure bleeder to purge ABS/modulator lines if applicable.
  • ABS-equipped units may trap air in a hydraulic control unit; if normal bleeding fails, cycle the ignition per manufacturer bleed procedures or consult a qualified technician.
  • Always use new, sealed DOT 4 fluid. Do not mix DOT 3, DOT 4, and DOT 5 (silicone) fluids.
  • If calipers are sticky or pistons don't return smoothly, clean and rebuild calipers or replace seals as needed.

Maintenance interval recommendation

Replace brake fluid every two years or sooner if fluid is dark or if the vehicle is used in heavy-duty work, towing, or wet conditions. Keep records of service dates and fluid type used.

What to watch for on the Outlander MAX 450 6x6 DPS

  • Because of the extra weight and cargo capacity of the 6x6 configuration, brakes may see higher duty cycles – stay proactive about fluid and pad inspections.
  • Inspect rear brake assemblies more frequently; the additional driven axle and load can accelerate wear.
  • If you added aftermarket accessories (winch, cargo racks, trailer wiring), ensure added loads don't overload the brake system and that wiring or mounts don't interfere with brake lines.

When in doubt or if ABS/hydraulic unit concerns arise, bring your Outlander MAX 450 6x6 DPS to a certified technician. Proper bleeding and fresh DOT 4 fluid restore braking performance and safety.
