This MotoSport guide walks you through a safe, thorough brake fluid change and bleed for the 2017 Can-Am Outlander MAX 850 XT. Follow these steps exactly, use quality tools and DOT-rated fluid, and observe all safety precautions. This procedure is written for the OEM hydraulic system as found on the 2017 Outlander MAX 850 XT; if your machine has aftermarket brake components or ABS, read the notes below before beginning.
Important model notes for the 2017 Can-Am Outlander MAX 850 XT
- The Outlander MAX 850 XT uses a hydraulic braking system with separate front and rear master reservoirs. Linked-brake variants may route pressure differently; bleeding order is determined by the master cylinder location and distance to each caliper.
- Factory-recommended brake fluid is DOT 4. If you choose DOT 5.1, it is acceptable only if compatible with seals; do not use silicone-based DOT 5. Confirm by checking the service manual or existing reservoir cap marking before starting.
- Some 2017 models may be equipped with ABS or a hydraulic limiter valve. If your machine has ABS, you must cycle the ABS pump and valves as part of the bleed procedure – see the ABS-specific note later in the guide.
- Brake lines, banjo bolts & fittings on the Outlander are aluminum/steel; inspect for corrosion and replace crush washers when loosening banjo fittings. Replace any line that is bulged, cracked, or shows soft spots.
Safety and preparation
- Work on a flat, stable surface. Block wheels and place the machine on a center stand or secure jack so wheels can rotate freely if required.
- Wear safety glasses and nitrile gloves. Brake fluid damages paint & plastics &mdash avoid spills; cover bodywork with rags or plastic.
- Have a waste container ready for old fluid. Brake fluid must be disposed of as hazardous waste.
- Recommended tools: clear plastic tubing that fits bleeder nipples snugly, a catch bottle, a wrench set (open-end), vacuum bleeder or hand pump (recommended), brake bleeder kit or helper, funnel, clean lint-free rags, and a torque wrench for reassembly if removing banjo bolts.
Fluids & parts to have on hand
- DOT 4 brake fluid (fresh, unopened container)
- New copper or aluminum crush washers for banjo bolts if you disconnect lines
- Replacement bleeder screws if the originals are corroded
- Clean funnels, rags, and isopropyl alcohol for cleanup
Overview of the bleed sequence
Always start bleeding at the brake caliper farthest from the associated master cylinder and work toward the master cylinder. On the Outlander MAX 850 XT this generally means:
- If bleeding the rear master circuit: bleed the rear caliper first.
- If bleeding the front master circuit: bleed the right/front passenger-side caliper (farthest) first, then the left/driver-side caliper.
If the machine has a combined or linked system, identify which master controls which caliper and follow farthest-to-nearest order for each circuit separately.
Step-by-step: Replace brake fluid and bleed (manual or vacuum method)
- Clean the reservoir caps and surrounding area. Remove the reservoir caps and diaphragm assemblies. Wipe away any grime to prevent contamination.
- Siphon or vacuum out as much old fluid from each reservoir as possible using a turkey-baster or syringe. Do not tilt the machine excessively; keep the master at normal orientation.
- Top the reservoir with fresh DOT 4 fluid to the full mark. Keep the cap off but protected to prevent debris entry.
- Start with the caliper farthest from the master cylinder. Fit clear tubing over the bleeder nipple and place the other end into a catch bottle partially filled with fresh brake fluid to prevent air being drawn back in. If using a vacuum bleeder, attach it to the bleeder nipple per tool instructions.
- Have an assistant slowly depress the brake lever or pedal several times and hold it down (or use the vacuum bleeder to draw fluid). Open the bleeder nipple one-quarter to one-half turn so fluid and air flow into the tubing/catch bottle. Close the nipple before the assistant releases the brake. Repeat until you see clear fluid with no bubbles. Always keep the reservoir topped up between cycles.
- Repeat the process at each caliper in the order specified above, maintaining reservoir level to avoid introducing air into the system.
- Once each caliper is bled and only clear, bubble-free fluid appears, complete a final bleed at the caliper nearest the master cylinder to ensure any trapped air is cleared.
- If you removed any banjo bolts or lines, ensure you reinstall with new crush washers and torque to correct spec; snug and then follow torque values in the service manual. Tighten bleeder screws finger-tight then to manufacturer spec; do not over-torque.
- With all bleeder screws closed, pump the brake lever/pedal several times to build firm pressure. Check for soft sponginess & repeat bleeding where needed.
- Clean any spilled brake fluid from painted surfaces with mild soapy water, then dry. Replace reservoir diaphragms and caps, and torque any fasteners removed to spec.
- Test the brakes at very low speed in a safe area before returning to normal riding. Confirm a firm lever/pedal feel and no fluid leaks.
If using a one-person vacuum or pressure bleeder
- Attach the device to the reservoir or bleeder nipple per the tool instructions. When using a pressure bleeder on the reservoir, set low pressure (2-4 psi) and open bleeders one at a time from farthest to nearest. When using a vacuum pump at the caliper, draw until clear fluid without bubbles emerges.
- Monitor reservoir level closely; never let it run dry.
ABS or valve-equipped machines
- If your Outlander MAX 850 XT is equipped with ABS, you must cycle the ABS pump and valves to purge trapped air in the hydraulic modulator. Consult the factory service manual for the ABS bleed procedure &mdash it usually involves powering the ABS system and actuating it while performing the bleed sequence.
- If you cannot perform the electronic cycling, have a dealer or qualified shop complete the ABS bleed to avoid air remaining in the modulator.
Troubleshooting
- Persistent spongy lever/pedal after multiple bleeds: check for a leak, contaminated master cylinder seals, or air trapped in ABS modulator.
- Brake lever that goes to the bar with fluid remaining: inspect caliper pistons and seals, master cylinder internal seals, and replace components as needed.
- Visible bubbles in reservoir while holding brake: indicates an internal leak between master and line or a poor bleeder seal; inspect fittings and bleeder screw condition.
Final checks & maintenance tips
- Always use fresh DOT 4; never mix in DOT 5 silicone fluid with DOT 3/4/5.1 systems.
- Replace brake fluid every 1-2 years or sooner if the fluid darkens or absorbs moisture; contaminated fluid reduces boiling point and braking performance.
- Inspect hoses, calipers, pads, and rotors while the system is open. Replace worn pads or damaged hoses promptly.
- Record the service date and mileage for maintenance history.
Following this MotoSport procedure will restore proper brake feel and hydraulic integrity for your 2017 Can-Am Outlander MAX 850 XT. If you encounter ABS-related complications or suspect internal master cylinder damage, consult a qualified technician or your authorized Can-Am dealer.
