This MotoSport proprietary guide walks you step-by-step through safely flushing and bleeding the hydraulic brake system on a 2009 Can-Am Outlander MAX 800R (MMY OLM800R). Follow these procedures exactly, use proper PPE, and consult your service manual for torque specs and special-service steps.

What you need

• DOT 4 brake fluid (fresh, unopened). The Outlander MAX 800R uses DOT 4; confirm capacity and spec in your manual.
• Clear plastic tubing to fit bleed nipples
• Catch bottle or reservoir for old fluid
• Brake-bleeder wrench or appropriately sized box wrench
• Vacuum/pressure bleeder or a second person for manual pump bleeding
• Shop rags, brake-clean spray, gloves, eye protection
• Torque wrench for reassembly (refer to factory specs)
• Small syringe or siphon to remove fluid from master reservoir

Safety & preparation

• Work on a level surface with the engine off and key removed. Secure the ATV on stands so wheels can turn freely if needed.
• Release the parking brake and put the transmission in neutral. If the Outlander has an optional parking brake engaged, disengage it before bleeding.
• Clean the master cylinder reservoir cap area thoroughly to prevent contamination.
• Wear gloves and eye protection; brake fluid damages painted surfaces and plastic. Immediately wipe spills and rinse with water.

Master cylinder & reservoir preparation

• Locate the front master cylinder reservoir (typically under the handlebar cover) and the rear reservoir if separate. Clean the area.
• Use a syringe or siphon to remove most old fluid from the reservoir without drawing in air. Leave a small amount to keep the system wet during the first cycles.
• Top reservoir with fresh DOT 4 fluid. Do not mix fluid types.
• Loosen and remove the reservoir cap diaphragm carefully; do not let dirt fall into the reservoir.

Bleeding sequence & general rules

• Always start bleeding at the wheel farthest from the master cylinder and work toward the nearest. On the Outlander MAX 800R that typically means: far rear, near rear, far front, near front. If in doubt, identify which caliper is farthest from the master cylinder and proceed accordingly.
• Keep the master reservoir level above the minimum while bleeding to avoid introducing air into the system.
• For best results use a pressure or vacuum bleeder. If using a two-person manual method, have the helper slowly depress the brake lever/pedal and hold it while you open the bleeder screw; close the screw before the helper releases the lever.

Step-by-step bleed procedure

1. Fit a clear hose over the caliper bleed nipple and route the other end into a catch bottle partially filled with clean brake fluid to prevent air draw back.
2. Crack the bleed nipple about 1/4 to 1/2 turn. Do not fully remove the nipple or damage the threads.
3. If using a vacuum bleeder, attach it to the hose and pull until fluid runs clear and bubble-free, maintaining reservoir level. If manual: have an assistant slowly pump the brake lever/pedal 3-5 times and hold; open the bleed nipple and let fluid/air escape; close the nipple; then have the assistant release the lever. Repeat until no air is visible and fluid is clear.
4. After each cycle, top the reservoir with fresh fluid. Never let the reservoir run dry.
5. When the caliper line is clear and stable, tighten the bleed nipple snugly. Avoid over-torquing; use factory torque specs where provided.
6. Move to the next caliper following the farthest-to-nearest order. Repeat until all calipers are clear.
7. After the final bleed, verify the reservoir is at the proper level and reinstall the cap and diaphragm. Wipe any spilled fluid and inspect for leaks.

Checking for proper operation

• With the ATV still supported, carefully press the brake lever/pedal several times. The lever should feel firm and consistent, not spongy.
• Lower the ATV and perform a slow, low-speed test in a safe area to confirm braking performance. Re-inspect fittings for leaks after the test.

Notes specific to the 2009 Can-Am Outlander MAX 800R (MMY OLM800R)

• The 2009 MAX 800R uses a Rotax V-twin powerplant and a heavy-duty braking system designed for two-up utility use. Proper bleeding is essential after towing or heavy-duty use where heat may have boiled fluid and introduced vapor.
• If your Outlander is equipped with an ABS or Traction Control option for that model year, the system may trap air in hydraulic circuits or in the ABS unit. ABS-equipped units sometimes require a dealership-level scan tool or a manufacturer-specific bleed cycle to purge air from the ABS pump/valves. If ABS is present and manual bleeding does not firm the lever, seek professional service.
• Parking brake components on the MAX may be mechanically linked to the rear calipers. Ensure the mechanical parking-brake mechanism is released while bleeding rear brakes to allow fluid to flow freely.
• Replace rubber hoses or collapsed lines if they swell or show age. Old hoses can trap air and reduce bleeding effectiveness.
• Brake fluid should be flushed every two years or sooner if contaminated or if brake feel degrades. Use DOT 4 only and avoid mixing DOT 3/5.1 unless manual allows it; mixing can reduce performance.
• Keep brake caliper mounting bolts, banjo bolts, and copper crush washers in good condition. Replace crush washers if removed to prevent leaks.

Common problems & troubleshooting

• Persistent spongy lever after bleeding: likely trapped air (repeat full sequence), collapsed hose, or ABS module airaddress accordingly.
• Brake lever sinks slowly under pressure: check for internal caliper or master-cylinder leaks and soft seals; rebuild or replace suspect components.
• Fluid contamination or dark fluid: perform a full flush and replace with fresh DOT 4.

Disposal & cleanup

• Dispose of old brake fluid according to local hazardous-waste regulations. Do not pour on ground or into drains.
• Clean any brake fluid from painted surfaces. If paint is damaged, touch up to avoid corrosion.
