This MotoSport proprietary guide walks you through safely replacing and bleeding brake fluid on a 2007 Can-Am Outlander MAX 400 XT (MMY OLM400XT 2007). It covers tools, fluids, model-specific notes, step-by-step procedures for both front and rear systems, common problems, and post-service checks.

Quick model notes & safety reminders

  • The 2007 Outlander MAX 400 XT uses separate front and rear hydraulic circuits: a handlebar master cylinder for the front brakes and a foot-operated master cylinder for the rear. Bleed and service each circuit independently.
  • BRP typically specifies DOT 4 brake fluid for this era of Can-Am. Use fresh, unopened DOT 4 fluid only; do not mix with DOT 5 (silicone) or contaminated fluid.
  • Brake fluid is hygroscopic and will damage painted surfaces. Protect bodywork and wipe spills immediately using water and a clean rag.
  • Work on a level surface, block the wheels, and wear eye protection and gloves. Keep a catch bottle and tubing ready to avoid contamination and spills.

Tools & materials

  • DOT 4 brake fluid (new, unopened bottle)
  • Clean turkey baster or syringe (for removing old fluid from reservoir)
  • Clear plastic tubing to fit bleed nipples and a catch bottle
  • Box-end wrench or flare-nut wrench for bleed nipples (typically 8 mm)
  • Torque wrench (for caliper bolts and bleed nipple final snugging)
  • Clean rags, isopropyl alcohol for cleaning, disposable gloves
  • Assistant (helpful for manual pedal/lever pumping) or a vacuum/pressure bleeder
  • Rubber caps for bleed nipples

Preparation

  1. Park ATV on level ground, put in park/neutral, and secure with chocks. Remove ignition key.
  2. Clean around master cylinder reservoirs and bleed nipples to prevent dirt entering system.
  3. Remove reservoir cap(s). If reservoirs have foam or filters, note their position and condition. Replace if deteriorated.
  4. If reusing the same bottle of fluid during the job, keep the bottle sealed between uses to prevent moisture pickup.

Procedure – Drain & refill whole system

Because the Outlander MAX 400 XT has two separate systems, repeat the procedure below for each circuit (front handlebar and rear foot-operated) separately.

1. Remove old fluid from reservoir

  1. Use a clean turkey baster or syringe to extract as much old fluid from the reservoir as possible. Dispose of contaminated fluid properly.
  2. Top the reservoir with fresh DOT 4 fluid, but do not overfill. Leave room for fluid movement while bleeding.

2. Locate bleed nipple & attach tubing

  1. Find the bleed nipple on each caliper. Slip clear tubing over the nipple and route it into a catch bottle partially filled with fresh fluid to avoid drawing air back in.
  2. Loosen the nipple about 1/4 to 1/2 turn; do not remove it.

3. Bleeding methods (choose one)

Manual (assistant)
  1. Have assistant apply and hold steady pressure on the lever or pedal. For front lever, squeeze and hold; for rear pedal, press and hold.
  2. Open bleed nipple briefly to allow fluid and air to flow into tubing, then close nipple before assistant releases lever or pedal. Repeat until no air bubbles appear in tubing and fluid is clear.
  3. Keep reservoir level topped off between cycles to avoid introducing air.
Pressure or vacuum bleeder
  1. Connect a pressure bleeder to the reservoir or a vacuum tool to the caliper bleed nipple per the tool manufacturer instructions.
  2. Operate until clear, bubble-free fluid flows. Monitor reservoir level to prevent it running dry.

4. Bleeding order

  • For each circuit, start with the caliper farthest from the master cylinder then move to the next farthest. On the Outlander MAX 400 XT this typically means bleeding the rear caliper farthest from the rear master and then the nearer caliper; for the front circuit, bleed the furthest front caliper first.
  • Because circuits are independent, do front system separately from rear system. Do not cross-contaminate reservoirs.

5. Tighten & final checks

  1. When no bubbles remain and firm lever/pedal feel is achieved, tighten bleed nipples to snug. Typical bleed nipple torque is low – snug then about 7–12 Nm final. Do not overtighten.
  2. Top the reservoir to the specified level and reinstall cap securely.
  3. Wipe all areas clean with isopropyl alcohol to remove any fluid residue.
  4. Check lever travel and pedal firmness. If spongy feel remains, repeat bleeding until solid.

Replacing entire brake fluid system (recommended every 1–2 years)

  1. Perform a full fluid flush by draining reservoirs and bleeding until new, clear fluid emerges at all bleed nipples. Use fresh DOT 4 only.
  2. If using a pressure bleeder, fill with new fluid and push old fluid out via bleed nipples, maintaining reservoir level.
  3. After flush, test ride at low speed in a safe area to confirm braking performance.

Common troubleshooting

  • Persistent spongy lever/pedal: likely trapped air or internal master cylinder seal leak. Repeat bleeding; if unresolved, inspect master cylinder for leaks or internal damage.
  • Brake fluid level dropping quickly: check for external leaks at calipers, hoses, lines, or masters. Replace leaking components immediately.
  • Contaminated or dark fluid that remains after bleeding: consider flushing lines and replacing rubber hoses if they are absorbing moisture or contaminants.

Torque & replacement parts notes

  • Caliper mounting bolts, master cylinder mounting bolts, and other brake hardware should be torqued to factory specs where available. If factory specs are not at hand, tighten caliper bolts to common small-vehicle ranges (typically 25–40 Nm) and confirm with service manual when possible.
  • Replace rubber seals, caps, or hoses showing wear. Use OEM or high-quality aftermarket parts designed for 2007 Can-Am Outlander MAX 400 XT for fit and safety.

Post-service checklist

  • Confirm no leaks, correct fluid level, firm lever/pedal feel, and full travel adjusted per manual.
  • Test brakes from low speed in a safe area before normal riding.
  • Record the date and mileage/hours of the fluid change for future maintenance scheduling.
