How to Bleed & Replace Brake Fluid on a 2008 Can-Am Outlander 800 XT

Shop parts for a 2008 Can-Am Outlander 800 XT ATV.

This MotoSport proprietary guide covers step-by-step fluid replacement and bleeding for the 2008 Can-Am Outlander 800 XT (MMY: CAN_AM;OL800XT;2008). It is written for owners who want a reliable, safe brake fluid service — not just a quick bleed. Follow the steps below exactly, use the recommended fluid, and address any worn hydraulic components discovered during the job.

Important model notes for the 2008 Outlander 800 XT

  • The Outlander 800 XT uses two separate brake circuits: the handlebar lever master cylinder for the front brakes and the foot pedal master for the rear. Bleed each circuit independently.
  • MotoSport recommends using DOT4 brake fluid for replacement; confirm the reservoir cap marking before starting. DOT5 silicone fluid is not compatible with DOT3/DOT4 systems.
  • This model generally does not include factory ABS. If your ATV has an aftermarket or factory ABS unit, follow a manufacturer-specific ABS bleed procedure before road use.
  • Inspect calipers, hoses, banjo fittings, and pads while bleeding. Replace damaged hoses or corroded fittings; dirty fluid often indicates internal corrosion or caliper wear.

Tools & supplies

  • DOT4 brake fluid (fresh, unopened)
  • Clear plastic tubing to fit bleeder nipples
  • Catch bottle partially filled with brake fluid to prevent air entry
  • Brake bleed kit or vacuum pump (hand pump or syringe alternative)
  • Socket set, wrench for bleeder nipples (typically 8mm or 10mm), screwdriver
  • Clean lint-free rags, nitrile gloves, safety goggles
  • Torque wrench for reassembly if available
  • Brake cleaner and small brush for calipers

Preparation

  1. Park on level ground and secure the ATV so it cannot move. Block wheels as needed.
  2. Clean the brake fluid reservoirs, cap area, and surrounding paint to prevent contamination.
  3. Remove the reservoir caps for both front and rear masters. Do not let dirt fall in. Use a clean rag to cover openings if you must pause.
  4. Top each reservoir with fresh DOT4 fluid to the recommended level. Do not overfill.
  5. Identify bleeder nipple locations on each caliper. Fit clear tubing over the nipple and route into the catch bottle with a small amount of fluid in the bottle to prevent air reentry.

Bleed order & method

Bleed each circuit separately. Start with the circuit farthest from its master cylinder if two calipers are on one circuit. Because the Outlander uses separate masters for front/rear, bleed all front calipers via the handlebar master first, then the rear via the pedal master.

Common methods (choose one):

  • Vacuum pump or pressure bleeder — fastest and least messy.
  • Manual two-person pump — one person pumps the lever/pedal while the other opens/closes bleeders.
  • Syringe or gravity drip — only for small top-ups or if no pump is available; slower and requires patience.

Step-by-step bleed (recommended vacuum or hand-pump method)

  1. Attach the clear tubing to the bleeder nipple and place the other end in the catch bottle.
  2. With the master reservoir open and topped, attach your vacuum pump to the bleeder nipple and apply steady vacuum.
  3. Open the bleeder nipple about a 1/4 turn. Allow fluid and air to draw out until you see only clear fluid with no bubbles. Close the nipple while maintaining vacuum, then release vacuum and detach.
  4. If using a hand-pump method: have an assistant slowly pull the lever/pedal several times then hold pressure. Open the bleeder to let fluid/air out, close it, then release the lever/pedal. Repeat until clear fluid appears.
  5. Keep the reservoir filled during the entire process. Never let the reservoir run dry — doing so will reintroduce air into the lines and require a full repeat.
  6. Work systematically through all calipers for that circuit. Typical order for multi-caliper front circuits is farthest then nearest, but because the Outlander front uses a handlebar master, bleed each front caliper completely before finalizing the master.
  7. After bleeding a circuit, pump the brake lever/pedal gently to confirm firm feel. If spongy, repeat bleeding until firm.
  8. Torque bleeder nipples to a snug setting (do not over-torque). If a torque spec is needed, use a moderate 8-12 ft-lb range for small bleeder screws or tighten to factory spec if known.

Reservoir refill & final checks

  • Top reservoirs to the correct level, replace caps and secure breather hoses.
  • Wipe all fittings and painted surfaces with brake cleaner. Remove any spilled fluid immediately — brake fluid damages paint.
  • Inspect hoses, banjo bolts and copper crush washers for leaks. Replace any leaking hardware; always use new crush washers when reassembling banjo fittings.
  • Perform a slow operational test: with the ATV still supported, apply brakes to confirm immediate, firm engagement. Then perform a low-speed brake test in a safe area to confirm full braking performance.

Disposal & maintenance notes

  • Dispose of used brake fluid as hazardous waste per local regulations. Do not pour on soil or down drains.
  • If brake fluid turned very dark or contained debris, consider inspecting/caliper rebuilding or replacing that caliper. Dirty fluid indicates internal system contamination.
  • Replace brake fluid every 1-2 years if you ride in high-humidity or heavy-use conditions; moisture absorption degrades DOT4 performance over time.

Troubleshooting

  • Spongy pedal/lever after bleeding: re-bleed, ensure reservoir never ran dry, check for leaks or compressible hoses; replace soft or swollen hoses.
  • Persistent air: use a pressure bleeder or perform the gravity/syringe purge method starting at the highest point in the line and moving downward.
  • Brake drag after bleed: check caliper pistons for proper retraction — clean and lubricate piston seals or replace caliper if seized.

Perform this service in a clean, well-lit area and do not rush. Proper brake function is critical to safe operation of your Can-Am Outlander 800 XT. For replacement parts compatible with this model, visit the MotoSport parts page above.
