This MotoSport proprietary guide walks you through safely draining, replacing and bleeding the brake system on the 2024 Can-Am Outlander MAX 450 6x6 DPS. Follow each step, use the recommended fluid, and observe safety cautions specific to the MMY model to ensure reliable stopping power and long brake component life.

What you need

  • DOT 4 brake fluid (use fresh, sealed container)
  • Clear plastic tubing that fits bleed nipples
  • Catch bottle or jar, partially filled with old fluid
  • Box or bench vise to hold fluid bottle for pressure/bleeder methods (optional)
  • 10mm or appropriate wrench for bleed nipples
  • Turkey baster or fluid syringe for reservoir cleanup
  • Shop rags, brake cleaner, gloves and safety glasses
  • Jack and stands or ramps if you prefer wheel removal for access
  • Helper (two-person pump-and-hold method) or a vacuum/pressure bleeder

Model notes — what owners of the 2024 Can-Am Outlander MAX 450 6x6 DPS should know

  • The Outlander MAX 450 6x6 DPS uses a closed hydraulic brake system with a single master cylinder reservoir located under the front storage/cover area; access can require removing the front cover panel.
  • DPS (Dynamic Power Steering) does not change brake bleeding order, but steering components can limit access to calipers on the front units — remove the wheel or position steering for easier access if needed.
  • The system is hygroscopic; MotoSport strongly recommends DOT 4 replacement fluid and replacing fluid every 1-2 years or sooner if color is dark or contaminated.
  • Avoid getting brake fluid on painted plastics or metal trim — it will damage finishes. Keep rags handy and rinse spills immediately with water.
  • If you have aftermarket accessories that route lines or mount near calipers, check hose routing and fasteners during the job to prevent rubbing or chafing after reassembly.

Preparation

  1. Park on level ground, set parking brake, and remove key. Block wheels and, if required for access, raise the machine and support securely with jack stands or ramps.
  2. Locate and clean the master cylinder reservoir. On the 450 6x6 DPS the reservoir sits under the front cover — remove cover and wipe the cap/area clean before opening to prevent contamination.
  3. Check current fluid level and color. If dark or contaminated, full replacement is recommended instead of partial top-up.
  4. Remove as much old fluid from the reservoir as possible using a turkey baster or syringe; do not reuse removed fluid.
  5. Refill reservoir with fresh DOT 4 to the specified max level. Keep the cap loosely in place while bleeding to minimize air entry but prevent debris falling in.

Bleeding order

MotoSport recommends bleeding the calipers from farthest to nearest relative to the master cylinder to evacuate trapped air. For the Outlander MAX 6x6 layout, typical sequence is:

  1. Rear most caliper(s) first
  2. Then middle/rear-axle caliper(s) if applicable
  3. Finish with front caliper(s) closest to the master cylinder

If you are uncertain which caliper is farthest from the master cylinder, identify the longest hydraulic line run and start there.

Bleeding methods

Choose one method below. MotoSport prefers a vacuum or pressure bleeder for clean, single-operator work but includes the two-person technique for field repairs.

Two-person pump-and-hold method

  1. Attach clear tubing to the bleed nipple and place the other end into the catch bottle partially filled with old fluid to keep air from reentering.
  2. Have your helper pump the brake lever several times and hold firm pressure (medium-firm) on the lever.
  3. Open the bleed nipple about a 1/4 turn to let fluid and air escape; close the nipple before the helper releases the lever. Repeat until clear, air-free fluid appears.
  4. Top up the reservoir frequently to prevent it from running dry — never let it go below minimum during bleeding.
  5. Work each caliper in the sequence until no air bubbles appear in the tubing and fluid is clear.

Vacuum bleeder method (recommended for solo work)

  1. Connect vacuum pump to bleed nipple with tubing. Place the other end into the catch bottle.
  2. Apply vacuum, then open the bleed nipple. Pump fluid into the bottle while watching the reservoir level.
  3. When clear fluid with no bubbles flows, close the nipple and release vacuum. Repeat on each caliper per sequence.
  4. Keep reservoir topped during the entire process.

Pressure bleeder method (fastest, cleanest)

  1. Install a pressure bleeder on the reservoir following the tool manufacturer instructions, charge to the recommended psi for ATV systems (low pressure — typically under 10 psi) to avoid sealing or damage.
  2. Open each bleed nipple in sequence and close when clear fluid flows. Monitor reservoir level and fluid color throughout.

Tips for a proper job

  • Always keep the reservoir above minimum to avoid introducing air into the master cylinder.
  • Work systematically and do not allow the system to run dry.
  • Replace rubber seals or bleeder screws if they are corroded or leak when closed.
  • If a caliper repeatedly spits air, inspect hoses and fittings for internal collapse or leaks and replace as necessary.
  • After bleeding, torque bleed screws snugly but do not over-torque; they are small and can strip threads or snap.

Final checks and road test

  1. Wipe down all fittings and remove tools. Replace reservoir cap and any removed panels.
  2. With the machine stationary, apply the brake lever/pedal several times until a firm feel is achieved. If the lever is spongy, re-bleed.
  3. Lower the machine, remove wheel blocks, and perform a slow test ride in a safe area. Confirm firm braking at low speed before normal use.
  4. After a few stops, check reservoir level again and top to max if necessary; inspect for leaks at calipers and hose fittings.

Disposal and maintenance notes

  • Used brake fluid is hazardous waste. Collect and dispose of it according to local regulations; do not pour it on the ground or into drains.
  • Record the service date and fluid type for future maintenance. MotoSport recommends checking the fluid visually every 6 months and replacing every 12-24 months depending on use and storage conditions.

Follow these steps for safe, reliable brake fluid replacement and bleeding on your 2024 Can-Am Outlander MAX 450 6x6 DPS. If you encounter persistent soft lever feel after multiple bleed attempts, consult a qualified technician for a system inspection or master cylinder servicing.
