This MotoSport guide walks you through flushing and bleeding the hydraulic brakes on a 2023 Can-Am Outlander 850 DPS. Follow these steps carefully, use the correct fluid, and observe safety precautions. This guide is proprietary to MotoSport and tailored to owners of the 2023 Outlander 850 DPS with Rotax 850 engine and Dynamic Power Steering (DPS).

What you need

  • Correct brake fluid (manufacturer specifies DOT 4 — confirm with your owner’s manual or MotoSport parts listing)
  • Clear plastic tubing that fits snugly over bleeder nipples
  • Catch bottle for old fluid
  • Brake bleeder kit or vacuum pump (recommended) or a second person for pump-and-hold method
  • Box wrench or socket set for bleeder nipples
  • Clean rags, gloves, eye protection
  • Torque wrench (for caliper or banjo bolts if you remove lines)
  • Clean container and funnel for fresh fluid, disposable tray for waste fluid

Safety and preparation

  • Work on a flat surface with the parking brake engaged and the machine off and cool.
  • Protect paint and plastics from brake fluid — it is corrosive. Cover bodywork with rags or plastic.
  • Wear gloves and eye protection. Dispose of old fluid according to local regulations.
  • Locate the master cylinder reservoir(s). On the 2023 Outlander 850 DPS you have the main front/rear hydraulic reservoir(s) near the handlebar area & under shrouds; remove shrouds or panels only as needed to access reservoirs and calipers.
  • Confirm bleed sequence in your owner’s manual if available. If not, use the conventional furthest-from-master sequence: rear caliper first, then right front, then left front.

Step-by-step brake fluid replacement and bleeding

1. Clean and inspect

  • Clean reservoir cap, surrounding area, calipers and bleeder valve area to prevent contamination.
  • Inspect brake lines for cracks, kinks, or leaks. Replace any damaged lines before bleeding.

2. Top off with fresh fluid

  • Open the reservoir cap(s) and remove the diaphragm/strainer. Top to the recommended level with fresh DOT 4 fluid. Do not let the reservoir run dry during the process.

3. Bleeding options

  • Vacuum/pressure bleeder (recommended): Connect to the bleeder nipple or reservoir and follow the tool instructions. Open bleeder nipple, pump fluid until clean, bubble-free fluid runs and no air appears.
  • Two-person pump-and-hold: One person slowly pumps the brake lever/pedal several times and holds it; the second opens the bleeder nipple to let fluid and air escape, then closes it before the lever is released. Repeat until clear fluid without air bubbles appears and lever feel is firm.
  • Gravity bleeding: Open bleeder and allow fluid to drip slowly. This is slower but can work; monitor reservoir level closely to avoid introducing air.

4. Bleeding sequence and technique

  • Start with the caliper farthest from the master cylinder. Typical sequence: rear caliper first, then right/front passenger side, then left/front driver side. If unsure, follow the vehicle manual sequence.
  • At each caliper: attach clear tubing to the bleeder nipple and submerge the other end in a small bottle part-filled with fresh brake fluid (or catch bottle) to prevent air reentry.
  • Crack the bleeder ~1/4 to 1/2 turn. Use the chosen method to force fluid through until it runs clear with no bubbles.
  • Keep reservoir topped between operations. Never let it go dry.
  • Tighten bleeder nipple to spec finger-tight plus a small wrench snug; don’t over-torque.

5. Final checks

  • With all calipers bled, pump the brake lever/pedal to confirm firm feel and consistent resistance. If soft or spongy, repeat bleeding.
  • Securely reinstall reservoir cap, diaphragm, and any removed shrouds or panels.
  • Check for leaks around bleeder nipples, banjo bolts, and line fittings after a short test ride.
  • Measure brake lever free play and pedal travel; adjust to spec if needed per the owner’s manual.

Model-specific notes for the 2023 Outlander 850 DPS

  • The Outlander 850 DPS uses Dynamic Power Steering which can mask steering loads; when servicing brakes, test braking performance carefully at low speed to re-familiarize yourself with the machine’s behavior under deceleration.
  • Access to the master cylinder reservoir may require removing small panels or the handlebar cover; keep track of fasteners and grommets to avoid rattles later.
  • If your model has linked or combined braking systems, the bleed sequence and number of reservoirs may differ. Confirm the brake plumbing layout before beginning — when in doubt, bleed every caliper individually and keep the reservoir topped.
  • Use only the specified fluid grade and avoid mixing different fluid types. Mixing DOT 3, 4, and 5.1 is possible (chemically compatible) but always follow Can-Am recommendations; never use silicone DOT 5 in systems designed for glycol-based fluids.
  • After replacing fluid, brake pads may bed differently; expect a short re-bed period and avoid aggressive braking until you confirm consistent performance.

Troubleshooting

  • Persistent spongy feel: re-bleed making sure reservoir never goes dry; check for soft hoses or internal master cylinder leaks.
  • Fluid remains dark quickly after replacement: contamination or caliper seals degrading. Inspect calipers and replace seals or calipers as needed.
  • Air keeps returning: check for leaks at hose connections, banjo bolts, or damaged master cylinder; replace faulty components.

Maintenance interval

MotoSport recommends replacing brake fluid every 1-2 years depending on use and exposure to moisture. Heavy use, wet conditions, or trailer storage may require more frequent changes to maintain braking performance and prevent corrosion.
