This step-by-step MotoSport guide explains how to drain, flush, and bleed the brake system on a 2012 Can-Am Outlander 800R (MMY CAN_AM;OL800R;2012). Follow these instructions carefully to maintain braking performance and safety. Use recommended parts and DOT specification fluid available from MotoSport when replacing components or topping off fluid.

Tools & supplies

  • DOT 4 brake fluid (clean, unopened container)
  • Clear plastic tubing that fits over bleeder nipples
  • Brake bleeder bottle or clean catch bottle with one-way valve
  • Wrench set for bleeder nuts (typically 8mm or 10mm)
  • Phillips & flat screwdrivers
  • Turkey baster or fluid syringe (for reservoir fluid removal)
  • Clean rags, gloves, safety glasses
  • Jack or ATV stand to lift wheels if needed
  • Torque wrench (for caliper & wheel fasteners)

Pre-checks specific to the 2012 Outlander 800R

  • Park on level ground, engine off, parking brake engaged. Remove key from ignition to avoid accidental start.
  • Inspect brake lines, calipers, and master cylinder for leaks, cracked hoses, corrosion, or damaged fittings. Replace any damaged parts before bleeding.
  • The Outlander 800R uses DOT 4 fluid from the factory. Do not mix DOT 4 with DOT 5 silicone fluid.
  • If the machine has ABS or antilock option, note that the ABS unit may trap air. If ABS is present and bleeding through the calipers does not restore firm pedal/lever feel, ABS-specific bleed procedures or a scan tool activation cycle may be required.

Safety notes

  • Brake fluid is corrosive to paint & plastics. Wipe spills immediately.
  • Never reuse removed brake fluid. Dispose of old fluid per local regulations.

Procedure: drain & replace brake fluid

  1. Remove reservoir cap(s) on front and rear master cylinders. The Outlander typically has a combined front/rear reservoir with internal divider; identify both chambers and keep caps covered to minimize contamination.
  2. Use a turkey baster or syringe to remove as much old fluid from the reservoir as possible. Dispose of it properly.
  3. Top the reservoir with fresh DOT 4 fluid to the upper fill mark. Keep fluid level monitored during the procedure to avoid drawing air into the system.
  4. Start with the wheel farthest from the master cylinder and work toward the closest. For most quads this means: rear wheel first, then passenger-side front, then driver-side front. If unsure, identify which caliper is farthest from the master cylinder and start there.
  5. Raise the wheel or place ATV on stand to access bleeder nipple if needed. Clean bleeder nipple and surrounding area.
  6. Attach clear tubing to the bleeder nipple and place the other end in a catch bottle partially filled with a little fresh fluid to prevent air being drawn back in.
  7. Have an assistant slowly pull and hold the brake lever (or press the brake pedal) while you open the bleeder nipple about a quarter turn. Fluid and air will flow into the tubing. Close the nipple before the assistant releases the lever/pedal. Repeat until no air bubbles appear and only clean fluid flows. Keep reservoir topped between cycles.
  8. Torque bleeder nipple to spec (light snug; typically 8-12 Nm depending on hardware) and wipe clean. Repeat for each caliper using the same process.
  9. After all wheels are bled, pump the brake lever/pedal with engine off to confirm firm pressure. If the lever feels spongy, repeat bleeding sequence.
  10. If the machine has ABS and the lever remains soft after conventional bleeding, perform ABS activation cycles per factory service procedure or consult a dealer. ABS units can hold air that requires pump/valve actuations to purge.
  11. Clean reservoir cap sealing surfaces and reinstall caps. Wipe all hardware and painted surfaces to remove spilled fluid.

Full system flush recommendation

For a full system flush remove old fluid from the reservoir, top with fresh fluid, then bleed each caliper until the fluid runs clear. Repeat reservoir draw-and-refill if fluid remains dark. Regular replacement interval is recommended every 1-2 years or sooner if contamination or moisture is suspected.

Torque & fastener notes

  • Bleeder nipple: snug to factory spec (do not overtighten).
  • Caliper mounting bolts: torque to factory spec to avoid warpage or thread damage.

Common issues & model-specific tips

  • Reservoir design – the Outlander 800R reservoir often has internal partitions; ensure you are topping both chambers if separate. Keep caps loosely seated when bleeding to avoid contamination but tight enough to reduce spillage.
  • ABS-equipped units – air trapped in ABS modulator requires either the OEM bleed routine or a specialized bleed kit/scan tool to cycle solenoids. If you cannot achieve firm brakes after standard bleeding, contact a MotoSport tech or dealer for ABS service options.
  • Leaky seals or corroded lines — if you find degraded hoses or leaking calipers, replace those parts before bleeding. Old rubber hoses can expand under pressure and mask bleeding efforts.
  • Use fresh, unopened DOT 4 only. Mixing fluids or using contaminated bottles can reduce boiling point and performance.

Verification & road/test checklist

  • With machine on ground and lights/engine off, confirm firm lever/pedal feel under steady application.
  • Perform slow-speed stops in a safe area to verify braking performance and check for leaks.
  • Recheck fluid level after a short test ride and top to full if needed.

Keep a maintenance record showing date and mileage/hours of brake fluid service. For replacement parts, DOT 4 fluid, or caliper/bleeder hardware specific to the 2012 Can-Am Outlander 800R, find MotoSport parts & accessories using the provided parts page link above.
