This proprietary MotoSport guide walks you through a safe, effective brake fluid replacement and bleed on the 2015 Can-Am Renegade 800R X XC. Follow each step carefully. If you're unsure at any point, stop and consult a qualified technician.
What you need
- DOT 4 brake fluid (fresh, unopened)
- Clear plastic hose to fit bleeder nipples
- Small glass or plastic catch bottle
- Brake bleeder wrench or appropriate sized wrench
- Vacuum or pressure bleeder (optional but speeds the job)
- Clean rags, shop towels, isopropyl alcohol
- Jack or ramps to raise the ATV and stands to secure it
- Gloves, eye protection
- Torque wrench (for caliper/bleeder hardware if specified)
Model-specific notes for the 2015 Renegade 800R X XC
- The front master cylinder/reservoir is located on the right handlebar near the throttle assembly; the rear master cylinder and reservoir are located adjacent to the rear brake pedal assembly. Clean both reservoir caps before opening to prevent contamination.
- This model uses DOT 4 fluid from the factory. Never mix DOT 5 (silicone) with DOT 3/4 systems.
- If your Renegade is equipped with an optional factory ABS unit, follow the ABS-specific bleeding sequence in the service manual or use a diagnostic/bleed tool compatible with the ABS module to purge air from the unit.
- Brake line routing on this model can trap air in low points; when bleeding keep reservoirs topped and use the correct caliper sequence to push air out toward the master cylinder.
- Brake system capacity is modest – work one circuit at a time to avoid overfilling and spilling fluid onto painted or plastic surfaces.
Preparation
- Park on level ground, set parking brake, remove key.
- Raise the ATV so wheels are off the ground and supported with stands for stable access to calipers.
- Clean reservoirs and surrounding area thoroughly with a rag and isopropyl alcohol to prevent contamination.
- Remove reservoir caps, diaphragms, and place a clean cloth around the opening. Keep the reservoirs covered with a clean piece of plastic to minimize exposure to air while you work.
- Inspect brake lines, fittings, calipers, and pads for leaks or damage. Replace any components that show wear or leakage before bleeding.
Bleed sequence & general method
Work one circuit at a time (front and rear). Keep reservoir fluid level maintained high during the entire process. Use one of these reliable methods:
Method A Manual two-person bleed (recommended if no tool)
- Attach a clear hose to the bleeder nipple on the caliper and route the other end into a catch bottle partially filled with fluid to prevent air re-entry.
- Have an assistant sit on the seat and slowly apply the brake lever or pedal to the required position and hold it (do not pump rapidly).
- Open the bleeder nipple about 1/4 turn to allow fluid and air to flow into the hose. Close the bleeder before the assistant releases the lever or pedal. Repeat until clear fluid with no bubbles appears, topping the reservoir between cycles.
- Torque the bleeder nipple snugly per factory specs or hand-tight plus a quarter turn; avoid over-torquing. Wipe any spilled fluid immediately.
- Repeat for each caliper according to sequence below.
Method B Vacuum bleeder or pressure bleeder (faster, recommended)
- Connect the vacuum line to the bleeder nipple or attach the pressure bleeder to the reservoir per tool instructions.
- Open the bleeder nipple and draw fluid until clear and bubble-free fluid exits, keeping reservoir topped with clean DOT 4 fluid.
- Close the bleeder nipple, remove the tool, and wipe clean.
Recommended bleed order
- Front calipers first (right front then left front) – this pushes air from front lines toward the master cylinder reservoir.
- Then bleed the rear brake (rear caliper last).
- If your Renegade has an integrated combined braking system (some model years use combined brakes), follow the combined-brake sequence: bleed the caliper farthest from the master cylinder first, moving toward the closest.
Finishing steps
- When all calipers are free of air and the fluid runs clear, top each reservoir to the fill line and reinstall diaphragms and caps securely.
- Clean any spilled brake fluid from painted or plastic parts with isopropyl alcohol immediately — brake fluid can damage surfaces.
- Lower the ATV and test brake lever and pedal firmness slowly at low speed in a safe area. If the brake feels spongy, re-bleed until solid feel is restored.
- Properly dispose of old brake fluid per local regulations & environmental guidelines.
Safety & maintenance tips
- Replace brake fluid every 1-2 years or sooner if exposed to water contamination or heavy use; moisture lowers boiling point and reduces performance.
- Always use fresh unopened DOT 4 fluid and keep containers capped. Do not reuse brake fluid.
- If you encounter persistent sponginess after repeated bleeding, inspect master cylinder, caliper seals, and lines for internal leaks or a failing master cylinder.
- Record the service date and mileage for your maintenance logs.
For any uncertainty about torque specs, ABS bleed procedures, or hydraulic component replacement on the 2015 Can-Am Renegade 800R X XC, consult the factory service manual or contact a certified Can-Am technician.
