How to Bleed & Replace Brake Fluid on a 2016 Can-Am Outlander MAX 450L DPS

This MotoSport proprietary guide walks you through bleeding and replacing the brake fluid on the 2016 Can-Am Outlander MAX 450L DPS. Follow these steps carefully to keep braking performance reliable and safe. Use only DOT 4 brake fluid unless you confirm a different spec from your owner's manual or a dealer.

Safety & preparation

  • Work on a cool machine, parked on level ground with the parking brake engaged.
  • Wear nitrile gloves and eye protection. Brake fluid is corrosive to paint & plastics.
  • Have rags, a catch container, clear vinyl tubing, a small wrench to fit the bleeder valves (usually 8mm/10mm), DOT 4 fluid, and a syringe or turkey baster for reservoir draining.
  • Protect painted surfaces with tape or rags before opening the reservoir cap.
  • Identify master cylinders: the Outlander MAX 450L DPS typically has a front master cylinder at the handlebar (front brakes) and a rear master cylinder near the left footbrake (rear brakes). Bleed each hydraulic circuit independently.

Overview of bleeding strategy

  • For each circuit (front and rear), bleed the caliper farthest from that circuit's master cylinder first, then proceed to the nearest.
  • Two common methods: two-person pump-and-hold, or one-person vacuum/pressure bleeder. Both are acceptable; vacuum or pressure bleeders reduce the risk of introducing air.
  • Keep the reservoir top level filled with fresh DOT 4 throughout the process to avoid drawing air into the system.

Step-by-step – drain old fluid and replace

  1. Clean the reservoir cap area and remove the cap & diaphragm. Note fluid level and color. If very dark, proceed to a complete replacement.
  2. Siphon or use a syringe to remove most of the old fluid from the reservoir. Wipe the reservoir clean. Refill with fresh DOT 4 to the full mark.
  3. Start with the circuit farthest from its master cylinder. For example, if the master cylinder for the front is at the handlebar, begin with the rear-most front caliper; if uncertain, visually confirm brake line routing.
  4. Place clear tubing over the caliper bleeder nipple and route into your catch container. Slightly loosen the bleeder nut (do not remove).
  5. Method A – Two-person pump-and-hold: Person A pumps the brake lever/pedal several times and holds firm. Person B opens the bleeder nut briefly to allow fluid & air to escape, then closes it before Person A releases pressure. Repeat until clear fluid with no bubbles exits. Keep reservoir topped up between cycles.
  6. Method B – Vacuum/pressure bleeder: Attach vacuum pump to the bleeder hose or use a pressure bleeder on the reservoir. Open the bleeder and run until clear, bubble-free fluid flows. Monitor reservoir level.
  7. After each caliper is finished, tighten the bleeder nut to manufacturer snugness (hand-tight plus a small fraction of a turn with a wrench). Avoid over-torquing.
  8. Proceed to the next caliper in order from farthest to nearest for that circuit. Finish by bleeding the caliper closest to the master cylinder.
  9. Once both circuits are bled and the fluid running clear, top the reservoirs to the proper level, reinstall diaphragms and caps, and wipe any spilled fluid from paint or plastic immediately.
  10. Cycle the brakes several times with the ATV on level ground to confirm firm lever/pedal feel. Road/test at low speed to verify braking performance before normal use.

Flushing the entire system (full replacement)

  • To fully replace old fluid, repeat the bleed process until the expelled fluid runs clear and the reservoir contains only fresh fluid. Expect multiple reservoir refills and repeated bleeding at each caliper.
  • If you have a pressure bleeder, attach it to the reservoir and pump fresh fluid through each caliper sequentially until clean fluid appears.

Tips & common issues

  • If brake lever/pedal stays soft after bleeding, re-check for air, leaky fittings, worn lines, or faulty master cylinder seals.
  • Replace rubber hoses that are swollen, cracked, or soft — old hoses can trap air and degrade braking response.
  • Use new crush washers on caliper bleeder fittings if applicable; damaged washers can leak or allow air ingress.
  • Dispose of old brake fluid per local hazardous-waste rules. Do not reuse or pour on the ground.

Model-specific notes for the 2016 Can-Am Outlander MAX 450L DPS

  • The Outlander MAX 450L DPS is a long-seat, two-up chassis with Dynamic Power Steering circuitry separate from brakes — steering system bleed procedures are not part of this brake guide.
  • 2016 models from Can-Am typically specify DOT 4 brake fluid from the factory. Confirm by checking the reservoir cap labeling or owner's manual before topping up.
  • Cowling & reservoir access — the front master cylinder on the handlebar is exposed; the rear master cylinder may be accessed under side panels. Remove or loosen panels carefully to avoid scratched plastics.
  • If your machine has been used in wet, muddy conditions or for heavy towing, inspect calipers, lines, and pads for contamination or accelerated wear when you service the fluid.
  • After bleeding, monitor brake feel closely for the first few rides; long-seat models carry passengers and cargo that change loading, so confirm consistent stopping under varying loads.

When to seek professional help

  • If you cannot achieve a firm brake lever/pedal after multiple bleed attempts.
  • If you detect internal master cylinder leaks, collapsed lines, or damaged calipers.
  • If you're uncomfortable working on hydraulic systems or lack proper tools (vacuum pump, appropriate wrenches, catch containers).

Routine brake fluid replacement every 1-2 years helps prevent internal corrosion & moisture buildup in the system. Proper bleeding and fresh DOT 4 fluid keep your 2016 Can-Am Outlander MAX 450L DPS braking crisp and safe.
