How to Bleed and Replace Brake Fluid on a 2011 Can-Am Renegade 500

This MotoSport guide walks you stepbystep through flushing and bleeding the braking system on a 2011 CanAm Renegade 500. The process removes moisture and contaminants, restores firm lever and pedal feel, and protects internal components. Follow all safety precautions and work in a clean, welllit area. This procedure is written specifically for the MMY CanAm REN500 2011 chassis and its common master cylinder/caliper layout.

What you need

  • DOT 4 brake fluid (BRP recommends DOT 4 for this model)
  • Clear 3/16" or 1/4" vinyl tubing
  • Small catch bottle or jar
  • Brake bleeder wrench or open wrench that fits bleed nipples
  • Turkey baster or syringe (for reservoir fluid removal)
  • Shop rags, gloves, eye protection
  • Optional: vacuum pump or pressure bleeder for faster, cleaner job
  • Copper crush washers for banjo bolts (inspect & replace if corroded)

Model notes & preliminary checks (2011 CanAm Renegade 500)

  • The brake reservoir is located under the handlebar shroud for the front/master cylinder and near the rear brake master cylinder on the frame for the rear system. Remove any small panels to access them.
  • This model typically uses conventional hydraulic calipers with banjo fittings at the caliper. Inspect banjo bolts and copper crush washers for corrosion — replace if compressed or rusty.
  • If the machine has aftermarket braided lines or ABS components, adapt the process: braided lines generally allow the same bleed method; ABS systems sometimes require a specific cycle or diagnostic tool to remove trapped air from modulators. If you have ABS, consult a dealer or MotoSport tech for the ABS bleed procedure.
  • For a 2011 Renegade with higher hours, inspect the master cylinder diaphragm and reservoir cap seal for cracking or hardened rubber; replace if degraded to prevent contamination.

Safety first

  • Work on a level surface with the ATV secured in park and engine off (or as instructed for specific brake systems).
  • Brake fluid damages paint and plastics & is toxic. Wear gloves and eye protection. Clean spills immediately.
  • Do not let the reservoir run dry at any point – that can draw air into the system and require extra bleeding.
  • Dispose of used fluid responsibly per local regulations.

Stepbystep: Complete flush & bleed

Note: There are two common approaches: manual twoperson bleeding and singleperson vacuum/pressure bleeding. Both are shown; choose whichever tools and help you have.

1. Prep

  • Park the Renegade upright on a stable stand so wheels can be rotated and calipers reach comfortable height.
  • Clean around reservoir caps, master cylinder, and bleed nipples to prevent dirt entry. Remove the reservoir cap and diaphragm carefully.
  • Siphon old fluid from the reservoir into a waste container using a turkey baster or syringe until mostly empty but not bone dry.
  • Top the reservoir with fresh DOT 4 fluid to just below the max mark. Keep the cap off but the reservoir full during the bleed.

2. Sequence

Bleed in this order for optimal air removal: farthest caliper first, then closer ones. For most Renegade layouts:

  • Rear caliper(s) first (if rear only: do rear).
  • Front caliper(s) next.
  • Master cylinder last if you suspect internal air.

3A. Twoperson manual bleed

  • Fit clear tubing over the caliper bleed nipple and route into a catch bottle partially filled with clean fluid to prevent air being sucked back in.
  • Person A pumps the brake lever or pedal slowly to build pressure and then holds it down.
  • Person B opens the bleed nipple about a quarter to a half turn until fluid flows and bubbles appear, then closes the nipple before Person A releases the lever/pedal. Repeat until no air bubbles appear in the tubing and fluid runs clear.
  • Top up reservoir frequently to avoid it running dry.
  • Torque the bleed nipple snug (do not overtorque) when finished and wipe clean.

3B. Singleperson vacuum or pressure bleeder

  • Attach the clear tubing to the bleed nipple and place the open end into a catch bottle.
  • Use a hand vacuum pump on the tubing at the bleed nipple or use a pressure bleeder on the reservoir per the bleeder tool instructions.
  • Operate the tool until fluid is clear and bubblefree, topping up the reservoir as required.
  • Close nipple and remove hose when satisfied. Clean any spills.

4. Master cylinder benching (if needed)

  • If lever or pedal still feels spongy after caliper bleeding, the master cylinder may contain air. Carefully remove the master cylinder reservoir assembly and benchbleed it following a pump and open/close sequence or use a small screwdriver to gently actuate the piston while porting fluid until bubbles stop.
  • Reinstall and perform a final system bleed to be sure no air remains.

5. Final checks

  • With bleed nipples closed, cycle lever/pedal firmly several times to confirm a firm, consistent feel.
  • Check for leaks at banjo bolts, couplers, master cylinder and bleed nipples. Inspect hose routing for chafe and secure with clips if needed.
  • Wipe off all fluid traces and reinstall reservoir caps and any removed panels.
  • Test ride slowly in a safe area to verify braking performance before aggressive riding.

Wear items & common replacements for a 2011 Renegade 500

  • Brake pads: check thickness; replace if near spec or glazed. Front pads on this model can wear quickly if ridden in mud or steep terrain.
  • Banjo bolt washers: always replace crush washers when disconnecting banjo fittings to ensure a leakfree seal.
  • Brake hoses: inspect for cracks, bulges or soft spots; replace if aged. Consider braided stainless lines if you want improved pedal feel, but keep original fittings.
  • Reservoir cap diaphragm & Orings: cheap parts that prevent contamination — replace if brittle.

Maintenance interval

MotoSport recommends replacing brake fluid every 1-2 years depending on exposure to water and heavy use. Frequent wet riding or trail use increases moisture absorption and shortens fluid life.

Troubleshooting

  • Persistent spongy lever after thorough bleeding: inspect for leak, collapsed hose, or seized caliper piston; benchbleed master cylinder.
  • If bubbles persist only under pressure: suspect a seal leak at the master cylinder or an internal vacuum leak; remove and inspect master cylinder components.
  • If ABS components are suspected to trap air, consult a dealer or MotoSport tech for the proper ABS cycle procedure.

Keep a maintenance log for your Renegade 500 noting fluid changes and pad replacements. Regular attention to the brake system ensures safe, reliable stopping power and extends the life of master cylinder and caliper components.
