Overview
This MotoSport guide covers safe, step-by-step replacement and bleeding of the hydraulic brake fluid on a 2007 Can-Am Outlander MAX 400 (MMY: CAN_AM;OLM400;2007). Work in a clean, well-lit area; brake fluid is hygroscopic and corrosive to paint and finishes. Use only DOT 4 brake fluid unless your factory manual specifies otherwise. Never mix DOT 5 silicone with DOT 3/4 systems.
Tools & materials
- DOT 4 brake fluid (fresh, sealed container)
- Clear vinyl tubing that fits snugly over bleed nipples
- Clean catch bottle or jar
- Wrench set (metric), plus further-required wrench for bleed nipples
- Brake bleeder kit or one-way valve kit (optional but helpful)
- Box end or flare wrench for banjo/bleed fittings
- Clean rags, shop towels, and gloves
- Floor jack or stands and wheel chocks (if removing wheels)
- Torque wrench for any reassembly (refer to factory specs)
Safety first
- Wear gloves and eye protection. Dispose of old fluid responsibly.
- Do not allow brake fluid to contact painted surfaces; rinse immediately with water if it does.
- Keep the reservoir cap closed between steps to minimize contamination and air entry.
Model notes for the 2007 Outlander MAX 400
The Outlander MAX 400 is a two-up ATV platform with hydraulic disc brakes front and rear. On this model, owners commonly encounter hardened or leaking master cylinder seals and occasional caliper sticking after years of use. Inspect banjo bolt washers/crush washers when you open the hydraulic lines — replace them if they are deformed. Check hose condition for cracking or swelling; replace hoses showing wear. While bleeding, confirm the reservoir and lines are free of rust or debris that could indicate internal master cylinder wear.
Fluid replacement & bleeding procedure
Follow these steps in order. If you are unsure at any point, stop and consult a qualified technician.
- Prepare the machine: Park on level ground, engage park/parking brake, chock wheels. Remove any body panels or wheels as needed to access bleed nipples and the brake fluid reservoir.
- Clean the reservoir cap area thoroughly before opening to prevent contamination. Remove the cap and diaphragm, then wipe out any surface grime.
- Top the reservoir with fresh DOT 4 fluid until it reaches the "MAX" mark. Do not overfill.
- Identify the master cylinder and bleed sequence: Bleed the caliper farthest from the master cylinder first, then proceed to the next-farthest, finishing with the closest. On many Outlander layouts this means rear caliper(s) first then front; if you are unsure which port is furthest, visually follow the brake lines from the master cylinder.
- Attach clear tubing to the bleed nipple and place the other end into a clean catch bottle partially filled with old fluid to prevent air re-entry. Keep the bleed nipple snug but closed.
- Have an assistant slowly squeeze and hold the brake lever or pedal. Open the bleed nipple about a quarter-turn to let fluid & air escape into the tubing. Close the nipple before the assistant releases pressure. Repeat pump/open/close cycles until fluid runs clean without bubbles.
- After each cycle, top the reservoir so fluid never falls below the minimum level. Running the reservoir dry will reintroduce air into the system.
- Work through each caliper in the proper sequence until all lines are bled and no bubbles appear. Typical signs of remaining air: spongy lever/pedal, low lever travel.
- Once bleeding is complete, tighten all bleed nipples to a snug fit. Clean any spilled fluid and reinstall the reservoir diaphragm and cap. Torque banjo bolts and any fasteners to factory specs if available; if you do not have the spec, tighten securely but avoid over-torquing.
- Test brake feel: With the vehicle still supported, operate the brake lever/pedal several times until it feels firm. If it remains soft, repeat the bleeding sequence.
- Lower the machine and perform a low-speed brake test in a safe area to confirm proper operation before riding at speed.
Additional tips & troubleshooting
- If you see persistent air or contaminated fluid despite proper bleeding, inspect the master cylinder for an internal leak or failure. A leaking master cylinder can suck air past worn seals.
- Sticky calipers often need cleaning, piston lubrication, or seal rebuilds. If a caliper will not move freely, remove and service it. Replace dust boots and seals as needed.
- Always replace crush washers when removing banjo bolts to prevent leaks.
- Store unused brake fluid sealed and discard old fluid at a hazardous-waste center.
Maintenance schedule recommendation
For reliable stopping performance, replace brake fluid every two years or sooner if it appears dark or contaminated. Inspect hoses, lines, and calipers annually or after heavy use.
Following these steps will restore firm pedal/lever feel and extend the life of the Outlander MAX 400 braking system. If you run into complications or the brakes do not perform correctly after bleeding, consult a certified mechanic for a pressure test and component inspection.
