This MotoSport-exclusive service guide walks you step-by-step through draining, flushing, and bleeding the brake system on a 2012 Can-Am Outlander MAX 800R (MMY OLM800R). Follow these directions carefully to preserve braking performance and avoid contamination of the hydraulic system.

What you need

• DOT 4 brake fluid (fresh, unopened)
• Clear plastic tubing that fits bleeder nipples
• Catch bottle for used fluid
• Disposable gloves, shop rags, safety glasses
• Brake bleeder pump or vacuum pump OR a helper for manual pedal/lever pumping
• 10 mm wrench (bleeder nipple) and appropriate tools to remove wheel panels as needed
• Torque wrench for caliper fasteners if you remove calipers
• Brake parts cleaner for spilled fluid

Important model notes for the 2012 Can-Am Outlander MAX 800R

• The Outlander MAX 800R uses a hydraulic braking system that accepts DOT 4 fluid. Do not mix DOT 5 silicone fluid with DOT 4.
• This model may have linked braking between front and rear circuits depending on trim and aftermarket changes. If you suspect a modified braking system or factory ABS hardware, consult a dealer before performing service.
• Reservoir location is on the handlebar master cylinder for the front/hand brake and a separate reservoir for the rear/foot brake on some configurations. Keep caps clean to avoid contamination when open.
• Brake fluid eats paint and plastic – protect bodywork and clean spills immediately with brake parts cleaner and water.
• If calipers or hoses appear damaged, replace parts before bleeding. Use MotoSport-supplied OEM or equivalent replacement parts when possible.

Preparation

• Park the ATV on level ground, secure with the parking brake off for rear bleeding steps where specified, and place on a stand that keeps wheels clear if you need wheel access.
• Remove any panels that obstruct access to bleeder nipples and reservoirs.
• Clean the reservoir caps and surrounding area. Remove the caps and cover the opening with a clean rag while you work to reduce dust entry.
• Top the reservoirs with fresh DOT 4 fluid to the max line. Keep the cap loosely installed between steps to prevent debris entry.

Bleeding strategy & order

Bleed the system starting with the caliper furthest from the master cylinder, progressing to the closest. On the MAX 800R this typically means:

• Rear caliper farthest from the master cylinder (often rear right)
• Rear caliper nearest the master cylinder (often rear left)
• Front caliper farthest from master cylinder (usually front right)
• Front caliper nearest master cylinder (usually front left)

If your machine uses a single combined reservoir for front & rear circuits, follow the same furthest-to-closest logic per circuit. If unsure, verify hose routing to determine which caliper is furthest.

Bleeding methods

Method A: Vacuum or pressure bleeder (recommended)

1. Attach clear tubing to the caliper bleeder nipple and place the other end into a catch bottle partially filled with used fluid.
2. Open the bleeder nipple about 1/4 turn with the wrench. Activate the vacuum or pressure bleeder per tool instructions so fluid flows from the caliper into the bottle.
3. Watch the reservoir and top with fresh DOT 4 fluid as needed to prevent air entry.
4. When clear fluid free of air bubbles flows, close the bleeder nipple while fluid flow is slow, then tighten securely.
5. Move to the next caliper in the sequence and repeat.

Method B: Manual pump & one-way valve

1. Attach clear tubing to the bleeder and submerge the free end in the catch bottle. Install a one-way valve on the hose if available to prevent air return.
2. With the bleeder closed, have a helper firmly pump the brake lever or pedal several times then hold pressure.
3. Open the bleeder nipple while the helper holds pressure so fluid and air exit. Close the nipple before the helper releases the lever/pedal.
4. Repeat pump–hold–open cycles until only clear fluid appears and no bubbles are present, topping the reservoir as needed.

Method C: Bench bleeding (master cylinder service or replacement)

• If removing or replacing the master cylinder, bench-bleed it before reinstalling using the manufacturer-recommended kit or procedure to remove internal air.
• After bench-bleeding, reinstall and then bleed each caliper on the vehicle as above.

Finishing steps

• After all calipers are bled in sequence and reservoirs remain full to the max line, pump the brake lever/pedal to confirm a firm, consistent feel. If sponginess remains, repeat bleeding on the circuit until solid feel is restored.
• Wipe any spilled fluid off painted surfaces immediately. Replace and tighten reservoir caps securely. Reinstall any removed panels.
• Properly dispose of used brake fluid per local regulations; do not dump into drains.
• Road-test the ATV at low speed in a safe area to confirm braking performance before normal use.

Torque & safety reminders

• Do not overtighten bleeder nipples – snug them securely and then a small additional fraction of a turn. If a specific torque is required for caliper bolts consult your factory service manual or MotoSport parts information for torque values.
• Never reuse brake fluid once removed from the system. Keep the DOT 4 bottle sealed until use and discard any fluid left in an open bottle after a service session if contamination is suspected.
• If you encounter persistent air in the system or a leaking hose/banjo fitting, replace the damaged component rather than repeating bleeding.

Recommended service interval

For reliable performance on the Outlander MAX 800R, replace brake fluid every 2 years or sooner if moisture contamination, soft lever feel, or significant color change is observed.

If you need replacement hoses, bleeder screws, caliper rebuild kits, or fresh DOT 4 fluid specifically matched to your 2012 Can-Am Outlander MAX 800R, use MotoSport parts to ensure fit and performance.
