This step-by-step MotoSport guide walks you through safely flushing and bleeding the brake system on a 2012 Can-Am Outlander MAX 400 XT. Follow these instructions precisely, wear eye protection and gloves, and work on a cool, level ATV. Use only fresh, high-quality DOT 4 brake fluid unless your owner's manual specifies otherwise.
Tools & supplies
- DOT 4 brake fluid (new, unopened bottle)
- Brake bleeder kit (vacuum pump or one-way-valve hose and clear tubing)
- Small clear tubing to fit bleeder nipples
- Catch bottles or jars
- 8mm or 10mm flare wrench (verify bleed nipple size on your calipers)
- Turkey baster or syringe
- Clean rags and brake-clean
- Jack or ramps and stands to safely lift and support the ATV
- Rubber caps to protect paint from spilled fluid
Model notes specific to the 2012 Outlander MAX 400 XT
- The Outlander MAX 400 XT uses hydraulic brakes that are sensitive to contamination from mineral oils and water. Always use DOT 4 and never allow petroleum products near the system.
- Reservoir location: the master cylinder reservoir is on the handlebar for the front brake and on the frame near the rear brake pedal for the rear circuit. Confirm which reservoir feeds which calipers before beginning.
- Some 2012 Can-Am brake linkages combine front and rear functions for the parking-brake/parking mechanism. If you have a linked or combined system, you may need to bleed both circuits independently; consult your owner's manual for the specific plumbing layout and confirm which reservoir feeds which caliper(s).
- Take care not to spill fluid on plastic, painted surfaces, rubber controls or the seat. Brake fluid can damage finishes. Wipe any spills immediately and rinse with water if necessary.
Preparation
- Park on level ground, engage park gear and disconnect the battery negative terminal for safety.
- Lift the ATV so wheels are off the ground and supported securely with stands. Remove splash guards if needed for caliper access.
- Clean the master cylinder reservoir cap area with brake-clean and a rag to avoid contamination when opened.
- Remove the reservoir cap and diaphragm; cover the opening loosely to keep dirt out while you work.
- Inspect hoses, lines and calipers for visible leaks, cracks or deterioration. Replace any suspect lines or components before bleeding.
Flush and refill procedure (recommended method)
- Top the reservoir with fresh DOT 4 brake fluid. Keep the cap loose but on-hand so nothing falls in.
- Start with the wheel farthest from the master cylinder. For many Outlander layouts this is typically a rear wheel or opposite-side front; confirm by tracing the hard lines from the master cylinder.
- Fit clear tubing over the caliper bleed nipple and route the other end into a catch bottle partially filled with fresh fluid to prevent air re-entry.
- Use a vacuum bleeder on the caliper bleed nipple or use the pump-and-hold method. If using the pump-and-hold method: have an assistant slowly depress the brake lever/pedal several times and hold it down while you open the bleed nipple to let fluid and air escape, then close the nipple before the assistant releases the lever/pedal. Repeat until clear, bubble-free fluid emerges.
- Keep the master reservoir level above the minimum mark during the entire process to avoid introducing air into the system.
- Work from the farthest caliper to the closest caliper relative to the master cylinder until each caliper gives only clear, bubble-free fluid. Typical sequence: far rear, near rear, far front, near front — confirm routing on your machine before starting.
- Periodically top the reservoir with fresh fluid. Never reuse fluid drained from the system.
- When bleeding is complete, tighten each bleed nipple to the correct snugness using a flare wrench and wipe all fittings clean.
Alternative: pressure or vacuum bleeder
If you have a vacuum bleeder or pressure bleeder, follow the manufacturer instructions. A vacuum bleeder on each caliper speeds the job and reduces the chance of introducing air. A pressure bleeder applied to the master cylinder reservoir can flush the whole system quickly — still proceed wheel-by-wheel and keep the fluid fresh.
Final checks
- With all bleed nipples closed, pump the brake lever/pedal to build firm pressure. The lever or pedal should feel solid with minimal travel.
- Check the reservoir level and secure the cap and diaphragm. Reconnect the battery negative terminal.
- Inspect hoses, calipers and fittings for leaks with pressure applied. Tighten if needed.
- Lower the ATV and perform a slow, controlled ride test in a safe area to confirm braking performance. Re-check fluid level and for leaks after the test rides.
Disposal & maintenance tips
- Dispose of old brake fluid per local hazardous-waste regulations.
- Brake fluid is hygroscopic; replace every 1-2 years or sooner if contaminated. Regular fluid maintenance prevents corrosion and maintains brake performance.
- If you notice a soft brake lever/pedal after bleeding, recheck for air, leaks, or worn components like pads or the master cylinder.
Performing a full brake-fluid flush and bleed on your 2012 Can-Am Outlander MAX 400 XT keeps stopping power reliable and helps prevent corrosion inside the system. If you encounter persistent sponginess or visible leaks, stop and have a professional technician inspect the system.
