How to Bleed & Replace Brake Fluid on a 2015 Can-Am Outlander 800R DPS

This MotoSport procedural guide walks you through safely flushing and replacing the brake fluid on a 2015 Can-Am Outlander 800R DPS and highlights model-specific notes every owner should know. Work in a well-ventilated area on a cool ATV, wear eye and skin protection, and keep used fluid away from painted surfaces.

What you’ll need

  • DOT 4 brake fluid (Can-Am specifies DOT 4 compatible fluid)
  • Clear tubing to fit bleed nipples and a catch container
  • Handheld vacuum or pressure bleeder (optional but speeds the job)
  • Wrenches for bleed nipples (typically 8 mm or 10 mm), rags, gloves
  • Syringe or turkey baster to remove reservoir fluid
  • New copper crush washers for banjo bolts (recommended if removing caliper lines)
  • Torque wrench (for final torque checks)

Model-specific notes for the 2015 Outlander 800R DPS

  • Brake system uses DOT 4 fluid; do not use silicone (DOT 5) or mix fluid types.
  • DPS (Dynamic Power Steering) is a separate hydraulic/electronic system — bleeding brakes does not service DPS, and DPS reservoir/lines are separate. Avoid cross-contamination.
  • Handlebar master cylinder controls front brakes; foot master cylinder controls rear brakes. Bleed each circuit independently.
  • Some 2015 models have integrated parking brake linkages on the rear caliper — inspect and re-secure linkage after working on rear caliper.
  • Protect plastic and painted surfaces from brake fluid; it will damage finishes.

Preparation

  1. Park on level ground, secure the ATV, and remove the key. Place the ATV on a stand so wheels can be contacted if needed.
  2. Clean the master cylinder reservoirs (front & rear) tops thoroughly to prevent contamination when opening.
  3. Remove reservoir caps and diaphragms; use a syringe or turkey baster to remove as much old fluid from each reservoir as possible. Refill with fresh DOT 4 to the specified level.
  4. Identify bleed nipple locations on each caliper and verify wrench sizes. Have clear tubing and a catch bottle ready.

Bleeding order and strategy

Always start bleeding from the caliper farthest from the master cylinder and work to the nearest. For the Outlander 800R DPS:

  • Front circuit: bleed the far-right or farthest front caliper first, then the other front caliper.
  • Rear circuit: bleed the farthest rear caliper first, then the nearer one. If system is a single rear caliper, just bleed that caliper.

Manual bench-style bleed (pump & hold method)

  1. Attach clear tubing to the bleed nipple, route to a catch bottle partially filled with fresh brake fluid to prevent air being drawn back in.
  2. Have an assistant slowly apply and hold the brake lever/pedal at medium pressure.
  3. Open the bleed nipple about 1/4 turn until fluid runs into the tubing. Close the nipple while the lever/pedal is still held. The assistant releases the lever/pedal only after the nipple is closed.
  4. Repeat pump/hold/open/close cycles until clear, bubble-free fluid flows. Keep the reservoir topped up during the entire procedure to avoid introducing air.
  5. Move to the next caliper following the bleed order and repeat.

Vacuum or pressure bleeder method (recommended for speed and cleanliness)

  1. Connect the vacuum bleeder to the bleed nipple or attach the pressure bleeder to the master cylinder reservoir per the tool’s instructions.
  2. Open each bleed nipple in the correct order until clear fluid runs and no air bubbles appear in the tubing.
  3. Close bleed nipples and remove the tool. Keep master reservoir level checked and topped with fresh DOT 4 during the process.

Finishing steps

  1. With all circuits bled, ensure bleed nipples are tightened to a snug value — typically 8–12 ft-lb (11–16 Nm) unless the factory torque is specified in your service manual. Replace any crush washers used on banjo bolts.
  2. Replace reservoir diaphragms and caps. Clean any spilled fluid immediately.
  3. Check lever and pedal firm feel; if spongy, repeat bleeding until firm.
  4. Inspect brake lines, calipers, and fittings for leaks during a short slow-speed test ride. Re-check reservoir fluid level and top as required.
  5. Dispose of old brake fluid per local hazardous-waste regulations.

Troubleshooting & safety tips

  • If you cannot achieve a firm lever/pedal — check for a leaking master cylinder, damaged lines, or stuck caliper pistons; these require repair or replacement.
  • Do not reuse brake fluid; always start with fresh sealed DOT 4 fluid.
  • Avoid overfilling the reservoir; allow room for fluid expansion and the diaphragm.
  • Keep brake fluid off plastics and painted surfaces; rinse immediately with water if contact occurs.
  • If you removed brake calipers or lines, replace copper washers on banjo fittings and torque bolts to spec.

Periodic maintenance recommendation

Flush and replace brake fluid every 1–2 years or sooner if the fluid appears dark or contaminated. Regular replacement preserves braking performance and protects internal seals.
