This MotoSport-exclusive guide walks you step-by-step through draining, flushing, and bleeding the hydraulic brakes on a 2008 Can-Am Outlander MAX 400 XT. Follow procedures exactly, work in a clean area, and dispose of old brake fluid responsibly.

Model notes for the 2008 Can-Am Outlander MAX 400 XT

  • The Outlander MAX 400 XT uses a hydraulic system with a primary master cylinder and caliper bleed nipples at each wheel. The brake fluid reservoir is located under the front plastic panel near the handlebars; access may require partial panel removal.
  • This model typically does not have an ABS system, but confirm by inspection. No ABS means a conventional wheel-by-wheel bleed sequence applies.
  • Brake lines and fittings on this ATV are compact and can be easily contaminated by dirt; keep caps on reservoirs and caliper nipples when not working.
  • Consult the owner's manual for the manufacturer-specified fluid type. When replacing fluid, use a fresh DOT-rated brake fluid that meets the manual requirement (many owners use DOT 4; check your manual or reservoir cap). Never mix DOT 5 silicone fluid with glycol-based fluids.

Tools & supplies

  • DOT-specified brake fluid (fresh, unopened)
  • Clear hose that fits snugly over bleed nipple
  • Clean catch bottle (marked for brake fluid)
  • Line wrench set (to avoid rounding bleeder nuts)
  • Screwdrivers or plastic trim tools to access reservoir
  • Torque wrench (for bleed nipple and caliper bolts)
  • Shop rags, gloves, safety glasses
  • Optional: vacuum or pressure bleeder for faster, cleaner bleeding

Preparation

  1. Park the ATV on level ground, set parking brake, kill the engine, remove key.
  2. Lift and support the machine so wheels with calipers are off the ground for full lever/pedal travel. Use secure stands rated for the ATV weight.
  3. Clean around the reservoir cap and caliper bleed screws to prevent dirt ingress. Remove the reservoir cap and top off with fresh fluid so the system never draws in air during the procedure.
  4. Place a shop rag under the caliper to protect finish from spilled fluid; brake fluid will damage paint and plastics.

Drain & replace fluid (full flush)

Do a full system flush rather than partial replacement for best results.

  1. Open the reservoir and remove as much old fluid as possible using a turkey baster or fluid transfer pump. Wipe the reservoir clean if contaminated and refill with fresh fluid to the max level.
  2. Start at the wheel farthest from the master cylinder and work toward the closest. For the Outlander MAX 400 XT typical order is: rear passenger-side, rear driver-side, front passenger-side, front driver-side — confirm visually which caliper is farthest from the reservoir on your machine.
  3. Attach clear hose to the bleed nipple and place the other end into the catch bottle partially filled with some fresh fluid to prevent air re-entry.
  4. Have an assistant slowly depress the brake lever or pedal several times and hold pressure. Crack the bleed nipple about a quarter turn until fluid and bubbles flow into the hose, then tighten nipple while the lever/pedal is still held. Repeat until no air bubbles appear and fluid running out is clear.
  5. After each wheel is bled, top up the reservoir to the max level. Never let the reservoir run low during bleeding.
  6. When all wheels are complete, pump the lever/pedal to confirm firm feel. If spongy, repeat the sequence until solid. If repeated attempts fail, inspect for damaged lines, a leaking master cylinder, or internal air pockets in hoses.

Single-point vacuum or pressure bleeder (optional)

If using a vacuum or pressure bleeder, attach per manufacturer instructions to the reservoir and/or bleed nipple. Use the same wheel sequence. A pressure bleeder speeds the process and reduces contamination risk; still monitor reservoir level and top off as needed.

After-bleed checks & torque

  • Confirm bleed nipples and caliper bolts are torqued to factory specifications. If you don't have the torque spec, tighten snugly and verify no leaks under pressure, then consult service manual for final torque values.
  • Clean any spilled fluid immediately with water then a mild detergent; brake fluid can damage plastics and painted surfaces.
  • Start the ATV and apply brakes at low speed in a safe area to confirm performance before riding normally.
  • Dispose of old brake fluid according to local hazardous waste rules; do not pour down drains.

Troubleshooting

  • Persistent spongy lever/pedal: likely remaining air, contaminated master cylinder, or an internal leak. Re-bleed and inspect lines for leaks or swelling.
  • No fluid at a caliper: check for clogged hoses or collapsed internal lines; replace damaged lines and repeat bleeding.
  • Leaking bleed nipple after tightening: replace the nipple and copper crush washer if present, then re-bleed.

Service tips specific to the Outlander MAX 400 XT

  • Take extra care removing the front plastics to access the reservoir – the MAX two-up bodywork can be snug and clips are easy to break.
  • If the master cylinder reservoir looks foggy or contains sediment, clean it thoroughly before refilling; contamination shortens component life.
  • Reserve time to inspect caliper pistons for corrosion and boot damage while bleeding; replace caliper seals or pistons showing heavy wear to prevent future air ingress.
  • Keep a small supply of DOT-specified fluid labeled for the ATV with your service kit – it's hygroscopic and should be used within the bottle's life once opened.

Maintenance schedule recommendation

Flush and replace brake fluid every 1-2 years or sooner if you see contamination, moisture-induced brake performance decline, or after water exposure. Regular inspections of lines, fittings, and caliper hardware at routine service intervals will extend system life.

Follow this MotoSport guide and you'll restore firm, reliable braking to your 2008 Can-Am Outlander MAX 400 XT. If uncertain about any step, consult a qualified technician.
