This MotoSport-proprietary guide covers the full brake-fluid replacement and bleeding procedure for the 2008 Can-Am Outlander MAX 500 (MMY OLM500). It includes the tools, fluid choice, step-by-step bleeding sequence, troubleshooting tips, and model-specific notes owners should know.
Safety & prep
- Work on a level surface with the engine off and key removed.
- Wear nitrile gloves and eye protection. Brake fluid is corrosive to paint and plastics.
- Have a fresh container of DOT 4 brake fluid only. Do not use DOT 5 (silicone) or mix fluid types.
- Have an appropriate wrench for caliper bleed nipples (commonly 8mm or 10mm), clear hose, catch bottle, and a turkey baster or siphon for reservoir fluid removal.
- Block wheels and lift the ATV securely if needed to access calipers and lines.
Model-specific notes for the 2008 Can-Am Outlander MAX 500
- The OLM500 uses hydraulic disc brakes front and rear without factory ABS on this model year. That makes manual bleeding straightforward but follow the sequence to avoid aeration.
- There are separate circuits for front and rear brakes; the front master cylinder is on the handlebar, the rear master cylinder reservoir is located near the engine/frame. Confirm which reservoir feeds which calipers before bleeding.
- Reservoir caps are plastic with a diaphragm; inspect for cracks and replace if brittle. A leaking cap can allow moisture ingress and reduce fluid life.
- Original equipment calls for DOT 4 fluid; a higher boiling point DOT 4 is recommended for heavy-use or towing. Replace rubber lines if dry-rotted or cracked — 2008 rubber hoses may be aged.
- If you plan to replace hoses or calipers, keep torque values and pad orientation consistent with factory service specs. If unsure, MotoSport parts include OEM and upgraded components for this model.
Recommended intervals
- Replace brake fluid every 12-24 months or sooner if fluid is dark or contaminated. Severe-use riders should do it annually.
Tools & supplies
- DOT 4 brake fluid (sealed container)
- Wrench set (8mm/10mm likely for bleed nipples)
- Clear plastic tubing and catch bottle
- Turkey baster or fluid siphon
- Brake cleaner, shop rags, disposable gloves
- Assistant to pump brake lever/pedal (optional but recommended)
Step-by-step: flush and bleed (complete replacement)
- Identify reservoirs and calipers: confirm which master reservoir feeds each caliper. On the OLM500 the handlebar reservoir feeds the front calipers; the rear reservoir feeds the rear caliper(s).
- Clean the reservoir cap area with brake cleaner. Remove the cap and diaphragm carefully. Use a turkey baster to remove most old fluid from the reservoir until it looks clear of debris.
- Top reservoir with fresh DOT 4 fluid, keeping it above the minimum level throughout the process to avoid drawing air in.
- Start with the caliper farthest from its master reservoir. For the front circuit this is typically the right/front; for the rear circuit bleed the caliper farthest from the rear master (if applicable). If unsure, use the conventional "farthest first" rule.
- Fit clear tubing over the bleed nipple and route into a catch bottle partially filled with a little fresh fluid to avoid sucking air back in. Place a wrench on the nipple.
- Have an assistant slowly depress the brake lever (front) or press the brake pedal (rear) and hold pressure. Loosen the bleed nipple about a half turn so fluid and air escape into the tubing. Tighten the nipple before the assistant releases pressure. Repeat until fluid coming out is clear and bubble-free.
- Keep reservoir topped up frequently; never let it run down to the min mark or air will enter the system and you must start over.
- Repeat bleeding at each caliper in the correct sequence (farthest to nearest relative to its master reservoir) until all circuits produce clear, bubble-free fluid.
- After final bleed, tighten bleed nipples to snug (do not overtighten). Wipe down components and reinstall the reservoir diaphragm and cap.
- Operate brake lever/pedal multiple times to confirm firm, consistent pressure. If spongy feel remains, repeat bleeding focusing on rechecking the farthest caliper and ensuring the reservoir never ran low.
- Dispose of used fluid properly; do not reuse or pour on the ground.
Single-person vacuum or pressure bleeding alternative
If you bleed solo, use a hand vacuum pump on each bleed nipple or a pressure bleeder on the reservoir. Follow the tool manufacturer instructions, and still follow the farthest-to-closest sequence. Always monitor reservoir level while the tool runs.
Troubleshooting
- Persistent sponginess: likely air still trapped or leaking component. Reinspect bleed nipples, caliper seals, hoses, and the reservoir cap for leaks.
- Fluid dark or contaminated soon after flush: check for internal caliper corrosion or a leaking master cylinder allowing contamination; replace suspect parts.
- Brake drag after bleeding: check caliper pistons and pads for sticking, torque caliper bolts to spec, and ensure hose routing is free of kinks.
After service checklist
- Confirm all fittings are tight and no leaks are present.
- Test brakes at low speed in a safe area before resuming normal riding.
- Record service date and fluid type for future maintenance.
- Inspect brake lines, pads, caliper boots, and reservoir cap for wear & replace as needed.
