Shop parts for a 2021 Can-Am Outlander 650 6X6 DPS ATV.
This MotoSport guide walks you through safely flushing and bleeding the brake system on a 2021 Can-Am Outlander 650 6X6 DPS. Follow these steps to remove moisture and contamination, restore firm pedal feel, and preserve braking performance. Read all steps before you begin and work in a clean, well-ventilated area.
What you'll need
- DOT 4 brake fluid (fresh, unopened)
- Brake bleeder kit (vacuum/pressure or clear tubing & catch bottle)
- Turkey baster or fluid syringe
- Wrenches for bleeder nipples (typically 8 mm)
- Clean rags, gloves, eye protection
- Flat surface, wheel chocks, jack & stands if needed
- Service manual or a torque wrench for reassembly checks
Model-specific notes for the 2021 Outlander 650 6X6 DPS
- The Outlander 650 6X6 DPS uses DOT 4 brake fluid; do not substitute DOT 3 or DOT 5 silicone fluid.
- The master cylinder reservoir is under the front handlebar cover on the dash area; keep the cap and diaphragm clean when opening.
- DPS (Dynamic Power Steering) is an electrical/hydraulic assist system separate from the brake circuit — do not add brake fluid to any DPS reservoir or components.
- Brake lines are routed and secured to bodywork on the 6X6 chassis. Inspect for chafing at mounting points unique to the 6-wheel configuration.
- If your unit has a rear carrier or added accessories, check for altered brake line routing after installation.
- Brake calipers on this model are traditional hydraulic calipers; bleeding order should be furthest from the master cylinder first.
Preparation
- Park on level ground, set parking brake, chock wheels. Remove seats or panels as needed to access the master cylinder reservoir and bleeder nipples.
- Clean the reservoir cap area. Remove the cap and diaphragm slowly to avoid stirring settled fluid. Siphon out old fluid from the reservoir with a turkey baster until level is low but not empty.
- Top the reservoir with fresh DOT 4. Keep a spare bottle nearby to maintain fluid level during bleeding.
- Locate bleeder nipples at each caliper. Identify which caliper is furthest from the master cylinder for sequence selection.
Recommended bleed sequence
Use the rule: furthest wheel from the master cylinder first, then next furthest, finishing with the closest. On the 6X6 configuration this typically means:
- 1) Rear outer-most caliper furthest from master
- 2) Rear inner/other rear caliper
- 3) Front passenger caliper
- 4) Front driver caliper (closest)
Confirm distance visually on your machine — if unsure, identify master cylinder location and choose the bleeder order by physical distance.
Bleeding procedure — one-person vacuum/pressure method (recommended)
- Attach a vacuum bleeder to the bleeder nipple or use a pressure bleeder on the master cylinder. If using tubing & bottle, fit clear tubing to the bleeder nipple and submerge the other end in fluid in a catch bottle to prevent air re-entry.
- Open the bleeder nipple about a quarter turn. If using a vacuum pump, draw fluid until clear, bubble-free fluid flows. If pressure-bleeding, pressurize the reservoir to the tool manufacturer's spec and open each bleeder until clear fluid flows.
- Continuously top the master cylinder reservoir with fresh DOT 4 during the process to avoid drawing air into the system.
- Close the bleeder nipple securely before removing the hose. Repeat for each caliper in the sequence until no air bubbles appear and fluid is clean.
Bleeding procedure — two-person manual method
- Person A sits on the machine and slowly depresses the brake pedal several times, then holds it down.
- Person B opens the bleeder nipple slightly; fluid & air will exit into tubing/bottle. Close the nipple before Person A releases the pedal.
- Repeat pump-hold-open-close cycles until only clear fluid appears. Keep the reservoir topped between cycles.
Finishing steps
- Ensure all bleeder nipples are tightened to spec after bleeding. Wipe any spilled fluid immediately — DOT 4 damages paint and plastics.
- Top reservoir to the proper level, reinstall diaphragm & cap, and secure any removed panels or seats.
- Test the brake pedal at low speed in a safe area. Expect a firm, consistent pedal. If the pedal feels spongy, repeat the bleed process.
- Dispose of old brake fluid responsibly per local regulations.
Inspection items & maintenance tips
- Inspect brake pads, rotors & calipers for wear and scored surfaces while wheels are off.
- Check brake hose routing on the 6X6 frame for chafe where the double-rear axle and cargo areas change line direction.
- Replace banjo bolts, crush washers, or bleeder screws if corroded or leaking.
- Bleed the brakes every 1-2 years or sooner if performance degrades or the vehicle has heavy water exposure.
- Record DOT 4 fluid change date in your maintenance log so you know when the system was last serviced.
If you run into stubborn air or intermittent pedal problems after a full bleed, the master cylinder, ABS modulator (if equipped), or improperly seated caliper pistons may require further service. Consult MotoSport's parts and service resources for replacement components and professional support.
