This MotoSport-exclusive guide walks you through replacing brake fluid and bleeding the hydraulic system on a 2018 Can-Am Renegade 570 MMY. Follow each step carefully for safe, reliable braking performance. Use DOT 4 brake fluid as specified by BRP and always follow safe disposal rules for used fluid.

What youll need

  • DOT 4 brake fluid (new, unopened)
  • Clear vinyl tubing sized to the bleeder nipple
  • Plastic catch bottle
  • Brake bleeder wrench or properly sized open-end wrench
  • Disposable gloves, safety glasses
  • Shop rags, brake cleaner
  • Jack or stand to lift the ATV safely (if needed)
  • Assistant or a hand/vacuum bleeder tool
  • Torque wrench (for any caliper hardware you remove)

Important model notes for the 2018 Renegade 570

  • The Renegade 570 uses a hydraulic disc brake system with a single master cylinder for the front and a separate master or pedal-actuated for the rear depending on configuration. Confirm which configuration your MMY has before starting.
  • BRP specifies DOT 4 fluid for optimal performance at operating temperatures; do not mix DOT 4 with silicone-based fluids.
  • Brake lines and bleed nipples on the Renegade are accessible but can be tight in the caliper pockets; use the correct wrench to avoid rounding nipples.
  • Avoid getting brake fluid on painted plastics or bodywork — it will damage finishes. Keep rags handy and clean spills immediately with water and brake cleaner.

Preparation

  • Park the ATV on level ground, engage parking brake, and remove the key. Work with the engine off.
  • If needed, lift the ATV so the wheels can turn freely. Support securely on jack stands.
  • Clean around each master cylinder reservoir and bleeder nipple to prevent contamination.
  • Remove the reservoir cap and diaphragm; cover the opening with a clean rag to prevent debris from entering.
  • Top the reservoir with fresh DOT 4 fluid and keep it full during the procedure to avoid drawing air into the system.

Bleed sequence (recommended)

Use the sequence that bleeds the farthest caliper from the master cylinder first. For the typical Renegade 570 setup, follow:

  1. Rear brake caliper (if rear master is separate, bleed its circuit independently)
  2. Right front caliper
  3. Left front caliper

If your machine has a separate rear master, treat rear as its own system and follow the same "farthest first" logic for any split systems.

Manual (two-person) bleeding method

  1. Have your assistant sit on the machine and repeatedly pump the brake lever/pedal slowly several times, then hold it to the stop. If using a pedal, block it with a strap or have the assistant hold it.
  2. Attach clear tubing to the bleeder nipple and route into a catch bottle partially filled with old fluid to prevent air returning into the system.
  3. Open the bleeder nipple ~1/4 turn. Fluid and air will flow into the tubing. Close the nipple before the assistant releases the lever/pedal. Repeat until no air bubbles appear and fluid is clear.
  4. Top the master cylinder reservoir as needed throughout to prevent air from being drawn in.
  5. Torque the bleeder nipple to spec and move to the next caliper following the sequence above.

Vacuum or pressure bleeder method

  1. Connect the vacuum pump to the bleeder nipple with clear tubing and open the nipple 1/4 turn.
  2. Operate the vacuum to draw fluid until you see clear, bubble-free fluid in the tubing.
  3. Close the nipple before removing tubing and move to the next caliper, keeping the reservoir topped up.
  4. If using a pressure bleeder on the master reservoir, pressurize to the tool manufacturers recommendation and open each bleeder until clear fluid emerges.

Replacing all brake fluid (full flush)

  • Start with a full reservoir of new DOT 4 fluid. Bleed each caliper until only new fluid appears in the catch bottle.
  • Work methodically through each caliper, keeping the reservoir topped off to prevent air ingestion.
  • Dispose of old fluid properly; it is hazardous waste.

Final checks

  • Ensure all bleeder nipples are tightened to their proper snugness. Avoid over-torquing to prevent damage.
  • Pump the brake lever/pedal several times to confirm a firm, consistent feel. If spongy, repeat the bleeding steps.
  • Clean any spilled fluid from brake components and bodywork. Check pads and rotors for contamination; if fluid contacted pads, replace pads and clean rotors per aftermarket practice.
  • Road-test at low speed in a safe area to verify braking performance before returning to full use.

Troubleshooting

  • Persistent spongy lever after bleeding: check for leaks, damaged lines, or a failing master cylinder. Air may remain trapped in caliper pistons; cycling pistons by repeatedly applying pressure while the bleed nipple is open can help.
  • No fluid flow from bleeder: ensure bleeder nipple is opened and tubing is secure; verify fluid path isnt blocked by an internal caliper clog.
  • Brake drag after bleeding: check caliper pistons arent stuck and that caliper slide pins move smoothly; reinstall hardware to correct torque values.

Maintenance intervals & owner tips

  • Replace brake fluid every 12-24 months or sooner if you ride in wet/muddy conditions frequently; moisture in brake fluid reduces boiling point and performance.
  • Inspect lines, fittings, and calipers during each fluid change for wear, cracking, or leaks.
  • Keep a small bottle of DOT 4 in your tool kit for emergency topping up, but avoid long-term storage once opened.
  • If youre unsure about master cylinder or ABS (if equipped) work, consult a certified BRP technician; incorrect procedures can compromise safety.
