This MotoSport branded guide walks you step-by-step through replacing and bleeding the brake fluid on a 2022 Can-Am Outlander MAX 450 6x6 DPS. Follow this procedure to restore firm brake feel, remove air and contaminated fluid, and keep your MMY ATV stopping safely.
Warnings & preparation
- Work on a cool machine on a flat, stable surface. Wear eye protection and gloves. Brake fluid damages paint & plastics; protect painted surfaces and wipe spills immediately.
- Brake fluid is hygroscopic. Replace fluid every 1-2 years or when contaminated. If brakes are spongy after riding in wet conditions, bleed immediately.
- Use DOT4 brake fluid unless the owner’s manual specifies otherwise. Keep the bottle sealed and clean.
- Have a proper waste container for old fluid; dispose of fluid per local regulations.
Tools & supplies
- DOT4 brake fluid (clean new bottles)
- Brake bleed kit (vacuum or pressure bleeder) or clear tubing and a catch bottle
- 10 mm or appropriate wrench for bleeder nipples and banjo bolts (verify size on bike)
- Small flat screwdriver, rags, shop towels, plastic wrap or tape to protect finish
- Torque wrench (for reconnecting banjo bolts, if removed)
- Hex key set and sockets to remove panels/wheels for access
Overview of the Outlander MAX 450 6x6 DPS brake system
The 6x6 DPS uses hydraulic brakes with a handlebar master cylinder for the front/brake lever and an integrated rear master/combined system for the rear brakes. There are multiple calipers on the rear tandem axle arrangement; treat each wheel caliper as a bleeding point. The general rule: bleed the caliper farthest from the master cylinder first, then proceed toward the closest caliper.
Step-by-step procedure
1. Locate reservoirs and calipers
- Identify the front/hand lever master cylinder reservoir and the rear reservoir (mounted near the frame or brake junction). Remove covers and diaphragm caps, keeping debris out.
- Clean the caps and surrounding area before opening.
2. Top up master cylinder(s)
- Fill each reservoir to the recommended level with fresh DOT4. Keep the cap loosely installed to limit contamination but allow venting.
3. Decide bleeding method
- Single-person: use a vacuum bleeder or pressure bleeder for best results.
- Two-person pump method: one person operates the lever/pedal, the other opens/closes bleeders.
4. Bleeding order
- Front (handlebar master): bleed farthest front caliper first, then nearest. For dual front calipers, start with the caliper farthest from the lever.
- Rear: treat the rear calipers as separate circuits. Start with the caliper farthest from the rear master cylinder and work inward toward the master.
- If unsure which caliper is farthest, follow the longest hydraulic line first.
5. Bleed each caliper
- Attach clear tubing to the bleeder nipple and submerge the other end in a small catch bottle partly filled with fresh fluid to avoid drawing air back in.
- Have a helper slowly depress the brake lever or pedal several times and hold pressure (or use the vacuum/pressure tool to draw fluid).
- Open the bleeder nipple about 1/4 turn while pressure is held. Allow fluid and bubbles to flow into the tube. Close the nipple before the lever/pedal is released.
- Repeat pump-open-close cycles until no air bubbles appear and fluid is clear. Keep master reservoir topped up during the entire process to prevent introducing air into the system.
- Tighten the bleeder nip to hand tight then to the manufacturer’s spec if available. Wipe away any spilled fluid immediately.
6. Replace fluid in master cylinder(s)
- Once all calipers are bled, drain and refill the master cylinder reservoirs with fresh DOT4, ensuring correct level at the max mark. Install diaphragms and caps tightly.
7. System check
- With engine off, cycle the brakes several times to build firm lever/pedal feel. Confirm there is no sponginess, no visible leaks, and bleeder nipples are snug.
- Start the machine at low idle and recheck brake feel, then perform a low-speed brake test in a safe area to verify stopping power.
Tips & things specific to the 2022 Can-Am Outlander MAX 450 6x6 DPS
- The Outlander MAX 6x6 has unique rear drivetrain packaging and tighter access to some rear calipers. Removing small panels or wheels may be required for clear bleeder access.
- DPS (dynamic power steering) does not alter the brake hydraulic layout, but watch wiring harnesses and power steering lines when removing panels to access calipers.
- Corrosion can form on hard-to-reach bleeder nipples if maintenance intervals are extended. Apply penetrating lubricant to stuck nipples and back off carefully to avoid rounding.
- If a banjo fitting is removed or disturbed, replace the crush washers and torque to spec. If you do not have the torque spec, snug and verify no leaks, then obtain the spec before high-load use.
- Because the machine may sit outdoors, moisture contamination is a common cause of degraded fluid on this model; schedule fluid replacement at least every 24 months or sooner for heavy wet use.
Troubleshooting
- Still spongy after bleeding: re-bleed entire system, ensure no air in reservoir, inspect for flexible line swelling or internal master cylinder leaks.
- Persistent leaks: replace seals, banjo bolts/crush washers, or caliper/line as necessary.
Aftercare
- Record the service date and fluid type. Inspect brakes and fluid level after the first few rides to confirm no leaks and consistent pedal feel.
- Clean any spilled fluid from painted surfaces with water and mild soap immediately.
Performing a full fluid change and a careful bleed restores braking performance and extends component life on your Can-Am Outlander MAX 450 6x6 DPS. If you encounter complex faults or suspect internal master cylinder or ABS/DPS related issues, consult a qualified technician.
