This MotoSport guide walks you through replacing the brake fluid and bleeding brakes on a 2019 Can-Am Outlander 850. It is written for the MMY Outlander 850 owner who wants a safe, repeatable, shop-quality result. Follow each step carefully and use the recommended tools and fluid.
Important notes specific to the 2019 Can-Am Outlander 850
- The Outlander 850 commonly uses DOT 4 brake fluid. Confirm on your brake fluid reservoir cap before purchasing fluid.
- Some 2019 Outlander models have antilock brake components or a combined master cylinder layout. If your ATV is equipped with ABS or electronic brake modules, bleeding sequence and procedures may require an OEM scan/bleed routine or a dealer visit.
- Brake lines and reservoirs are plastic – avoid harsh solvents and keep fluid off paint and plastics, or it will damage finishes and components.
- If you have ramps or winches installed near the master cylinder or calipers, ensure cables & hardware don't interfere with pedal/lever movement during bleeding.
Tools & supplies
- DOT 4 brake fluid, unopened until use
- Clear vinyl tubing sized to bleed nipples
- Catch bottle and clean disposable rags
- 8mm or 10mm wrench for bleed nipples (verify size on your calipers)
- Vacuum pump bleeder or pressure bleeder (recommended) or a helper for two-person bleed
- Brake cleaner, gloves, eye protection
- Torque wrench for banjo bolts (if removing lines)
- Service manual or factory torque specs for caliper/banjo bolts
Preparation
- Park on level ground and secure the Outlander with the parking brake engaged. Block wheels to prevent movement.
- Clean the master cylinder reservoir cap area to prevent contamination. Remove the cap and diaphragm carefully — do not let dirt fall into the reservoir.
- Note the old fluid color. Dark, brown or cloudy fluid indicates it needs replacement.
- If you'll be replacing the fluid system-wide, start with a full reservoir purge rather than just topping off.
Step-by-step fluid replacement & bleeding
Use the sequence that matches your model: Bleed farthest caliper from the master cylinder first, finishing with the closest.
- Top the reservoir with fresh DOT 4 fluid. Never reuse drained fluid.
- Attach clear tubing to the bleed nipple on the farthest caliper. Put the other end into a catch bottle partially filled with fresh fluid to prevent air draw-back.
- If using a vacuum bleeder: attach vacuum to the tubing at the nipple and pump until clean fluid with no bubbles flows. If using a pressure bleeder: pressurize reservoir per tool instructions and open nipples until fluid is clear. If two-person: have helper slowly depress the brake lever/pedal while you open the nipple, then close the nipple before release. Repeat until no air and fluid is clear.
- Keep reservoir level above the minimum mark at all times. Refill as needed to prevent drawing air into the master cylinder.
- Work through each caliper or wheel cylinder in order from far to near. For many Outlanders that means rear passenger side, rear driver side, front passenger, then front driver side — confirm your vehicle layout before starting.
- After all points are bled, apply steady brake lever/pedal pressure for 30 seconds with engine off and check for any feel change. If the lever is spongy, repeat bleeding until firm.
- With a helper holding steady pressure, tighten all bleed nipples to specified snugness and check hoses & banjo bolts for leaks. If you removed any banjo bolts, torque to factory spec and replace crush washers.
- Top off reservoir to the correct level, reinstall diaphragm & cap, and clean any spilled fluid with brake cleaner.
Final checks
- Verify pedal/lever firmness at rest and during a slow test ride at low speed in a safe area.
- Inspect for leaks, hose chafing, damaged fittings, and ensure ABS warning (if equipped) clears on startup. If ABS light remains, dealer diagnostics may be required.
- Properly dispose of old brake fluid according to local regulations.
Troubleshooting & cautions
- If brakes remain soft after repeated bleeding, suspect a leaking master cylinder, internal ABS unit air, or collapsed flexible hose. Replace components as needed.
- Do not mix DOT 3 and DOT 5 fluids. DOT 5 is silicone-based and incompatible with DOT 4 systems.
- Avoid prolonged contact of brake fluid with paint and plastic. Rinse immediately with water if contact occurs.
- If your Outlander has electronically-assisted or ABS braking, some pumps cycle valves during bleed — using a pressure bleeder or dealer procedure limits trapped air in the module.
Routine maintenance tip
MotoSport recommends replacing brake fluid every 1-2 years depending on use and stored moisture to maintain braking performance and prevent corrosion inside the system.
