This MotoSport-exclusive service guide walks you step-by-step through flushing and bleeding the brake system on a 2020 Can-Am Renegade 570 X MR. Follow these instructions carefully for safe, reliable braking performance. This procedure is written specifically for the MMY (Make/Model/Year) listed and highlights model-specific details owners need to know.

Why replace brake fluid

Brake fluid absorbs moisture over time, which lowers boiling point and can cause spongy brakes or internal corrosion. Replacing fluid and properly bleeding the system restores pedal feel and extends component life.

What you need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear plastic tubing that fits snugly over the bleeder nipples
  • Brake fluid catch bottle or jar
  • Wrench for bleeder nipples (typically 8mm or 10mm; confirm fit)
  • Socket set and basic hand tools to access calipers and reservoir
  • Turkey baster or fluid syringe (to remove old fluid from master cylinder reservoir)
  • Gloves, eye protection, shop rags, and a drip pan
  • Assistant to operate the brake lever/pedal for two-person bleeding, or a one-way vacuum bleeder for solo work
  • Replacement crush washers for banjo bolts if you remove lines

Model-specific notes for the 2020 Renegade 570 X MR

  • The brake master cylinder reservoir is located under the left front cowling area; it has a small plastic cap and a rubber diaphragm. Keep the reservoir cap clean & upright to avoid contamination while servicing.
  • The 570 X MR typically uses DOT 4 fluid from the factory. Do not mix DOT 5 silicone fluid with DOT 4.
  • Some Renegade 570 models have a separate rear master or integrated ATV brake distribution valve — inspect your machine to identify front and rear bleed points before starting.
  • The Renegade is often used in mud & water environments; check caliper seals and lines for contamination or damage while bleeding. Replace any degraded hoses to prevent air ingress later.
  • If you encounter stubborn caliper bleeder screws that are corrosion-seized, apply penetrating oil and allow time to soak. Avoid rounding bleeder hexes by using the correct wrench and steady pressure.

Safety and prep

  • Work on a level surface with the machine secured in park and engine off.
  • Wheel chocks and a stable jack or stands are recommended if you remove wheels to access calipers.
  • Brake fluid damages paint & plastics. Wipe spills immediately and always keep rags and water nearby.

Step-by-step fluid replacement & bleeding

1. Inspect & prepare

Clean the reservoir cap area thoroughly. Remove cap and diaphragm. Siphon out most of the old fluid using the turkey baster or syringe, leaving a small amount so air cannot be introduced to the system.

2. Top reservoir with fresh DOT 4

Fill to the max mark. Keep the reservoir topped during the entire bleed process to prevent air re-entry.

3. Locate bleed screws

Identify the bleed nipple(s) on each caliper and the rear brake as required. Typical sequence: farthest wheel from master cylinder first, then closer wheels, finishing with the closest. For most Renegade layouts this means: rear, then front (left/right) — confirm system routing on your machine before starting.

4. Two-person bleeding method (recommended)

  1. Have your assistant slowly depress the brake lever or pedal several times and hold it down.
  2. Open the bleeder screw slightly to allow fluid and air to escape into the clear tubing and catch bottle. Close the bleeder screw before the assistant releases the lever/pedal.
  3. Repeat until clear, bubble-free fluid flows and the pedal/lever feel is firm. Monitor reservoir fluid level and refill as needed.
  4. Work from farthest caliper to nearest. For the Renegade, when in doubt, bleed the rear system first, then the front calipers individually.

5. One-person vacuum or pressure bleeding

If using a vacuum pump or pressure bleeder, follow the tool manufacturer instructions. Maintain the same wheel sequence & ensure the reservoir never runs low.

6. Final checks

  • After bleeding each circuit, tighten bleeder screws to proper snugness. If you removed banjo bolts or lines, replace crush washers and torque to spec found in the service manual.
  • Top the reservoir to the MAX line, reinstall diaphragm & cap, and clean any residual fluid.
  • Operate brake lever/pedal several times to confirm firm feel with no sinking. Start the engine and test brakes at low speed in a safe area before normal riding.

Troubleshooting

  • Persistent spongy lever after proper bleeding may indicate a caliper piston seal leak, internal master cylinder issue, or collapsed hose — inspect components and replace as needed.
  • If air keeps returning, check for porous or cracked hoses, loose fittings, or a leaking master cylinder seal.
  • Stiff pedal but poor braking can indicate glazed pads or contaminated rotors — clean or replace pads/rotors if contaminated with fluid.

Maintenance tips & intervals

  • MotoSport recommends replacing brake fluid every 1-2 years for machines used in wet, dusty, or heavy-use conditions; annual replacement is a safe practice for trail/utility use.
  • Inspect lines, fittings, calipers, and pad thickness whenever you service the fluid. Replace soft or cracked hoses and worn pads promptly.
  • Store spare DOT 4 fluid sealed and away from moisture to avoid contamination.

Notes specific to your MMY Renegade 570 X MR

  • Because the X MR is often ridden aggressively in rock & mud terrain, check caliper dust boots and pistons for grit ingress after every aggressive outing.
  • If you carry your ATV through deep water crossings, dry the brake components and re-check seals and fluid after the ride; water contamination accelerates fluid degradation.
  • Keep a small bleed kit and spare DOT 4 in your trailer or truck for remote trail maintenance — an ounce of prevention prevents a big recovery operation.
