This MotoSport-exclusive procedure walks you through safely flushing and bleeding the brake system on a 2018 Can-Am Renegade 1000R. Follow each step carefully, use quality parts and DOT-rated fluid, and read safety notes for this MMY ATV before starting.
Important model notes for the 2018 Can-Am Renegade 1000R
- Factory-specified fluid is DOT 4 or as marked on the reservoir cap – verify cap marking before buying fluid.
- Some Renegade 1000R units may have ABS or advanced braking options; if your unit has ABS, consult a dealer or a professional if you encounter ABS-related bleeding steps or warning lights.
- There are separate master cylinders/reservoirs for front and rear circuits on many Renegade models. Treat each circuit individually.
- The Renegade uses accessible bleed nipples on each caliper; clean them before opening to prevent contamination.
- Wear gloves and eye protection. Brake fluid is corrosive to paint and plastic — wipe spills immediately.
Tools & supplies
- DOT 4 brake fluid (new, unopened)
- Brake bleeder wrench or appropriate sized open-end wrench
- Clear plastic tubing to fit bleed nipple
- Catch bottle partially filled with a little fluid to prevent air ingestion
- Brake bleeder kit or one-way vacuum bleeder (optional but speeds process)
- Clean rags, gloves, safety glasses
- Torque wrench (for caliper hardware if removed)
- Shop manual or notes for brake caliper torque specs (do not overtighten)
Preparation
- Park on a flat surface, engage parking brake, and disable the engine. Remove key.
- Clean the area around each brake fluid reservoir cap and the calipers to prevent dirt entering the system.
- Identify all bleed nipples: front left, front right and rear caliper(s). The Renegade 1000R commonly has two front calipers and one rear caliper; confirm your setup.
- Open the reservoir cap(s) slowly and inspect fluid color. Dark, contaminated fluid indicates replacement is overdue.
Basic two-person bleed method (recommended for most DIYers)
- Start with the caliper farthest from the master cylinder. On most Renegades that means: right rear (if applicable), then left rear/front depending on routing – consult your bike to confirm order. A safe order is: rear caliper, right front, left front if unsure.
- Attach clear tubing to the bleed nipple and submerge the far end into a catch bottle with a small amount of fresh fluid to stop air re-entering.
- Have an assistant slowly depress the brake lever/pedal several times and hold it down.
- With lever held, open the bleed nipple 1/4 to 1/2 turn. Fluid and air bubbles will flow into the tubing. Close the nipple before the assistant releases the lever.
- Repeat pump-hold-open-close cycles until you see clean, bubble-free fluid exiting and the lever feel firm.
- Keep the reservoir topped with fresh fluid throughout the process to avoid drawing air into the master cylinder.
- Once the caliper is clear, tighten the bleed nipple to spec snugness (do not over-torque). Move to the next caliper and repeat.
One-person vacuum or pressure bleeder method
- If using a vacuum bleeder: attach vacuum to the bleed nipple tubing and set the reservoir open to atmosphere. Activate vacuum and open nipple; monitor fluid until clear. Close nipple and release vacuum.
- If using a pressure bleeder: follow tool instructions, pressurize reservoir, then open bleed nipples in the correct order until clear fluid appears. Pressure systems can force debris through — use filter-equipped tool and clean reservoir first.
After bleeding
- Confirm pedal/lever firmness at normal operating pressure. If spongy feel remains, repeat bleeding sequence or inspect master cylinder and calipers for leaks or internal problems.
- Clean any spilled brake fluid immediately to avoid paint/plastic damage.
- Properly dispose of old brake fluid per local hazardous waste rules.
- Reinstall and secure reservoir cap. Check for leaks after a short test ride at low speed in a safe area before heavy use.
Troubleshooting & checks specific to the Renegade 1000R
- If lever travel is excessive after bleeding, check for worn pads, worn master cylinder seals, or internal caliper issues.
- If the unit has ABS and a warning light appears after bleeding, cycle ignition and recheck fluid levels. If light persists, professional diagnostic equipment may be required to reset the ABS module.
- Inspect brake lines for cracking, hardening or swelling — replace any suspect hoses with OE-quality or better lines sold through MotoSport.
- Pad wear: many Renegade users find aggressive riding accelerates front pad wear. Inspect pads while bleeding; replace if thickness is below spec.
Maintenance intervals
For reliability and corrosion prevention, replace brake fluid every 1-2 years or sooner if the fluid darkens. Aggressive riders or wet/muddy use may require more frequent service.
Final safety reminder
Do not ride until brakes are tested and confirmed to be fully functional. If you are uncomfortable with any step or if ABS complications arise, have a professional technician perform the service.
