How to Bleed & Replace Brake Fluid on a 2009 Can-Am Renegade 800R X

This MotoSport guide walks you through a safe, repeatable procedure to flush and bleed the brake system on a 2009 Can-Am Renegade 800R X. Follow these steps carefully — proper brake service is critical for safe operation. This article is proprietary to MotoSport and tailored to the Renegade 800R X.

Notes specific to the 2009 Can-Am Renegade 800R X

  • Factory system uses DOT 4 brake fluid. Never mix DOT 4 with DOT 5 (silicone).
  • The Renegade 800R X has separate front and rear master cylinder reservoirs; the front master is shared for both front calipers, rear master serves the rear caliper. Confirm reservoir locations before starting.
  • ABS was not standard on most 2009 Renegade 800Rs. If your machine has an ABS unit, bleeding order and procedures may differ; consult dealer service data before attempting.
  • Brake lines on this model route near painted panels and plastic. Avoid spilling fluid on paint or plastic – DOT 4 will damage finishes. Keep shop rags or fluid catchers handy.
  • Replace rubber hoses older than 5-7 years or showing cracks/swelling. Inspect caliper pistons and seals for leaks when bleeding.

What you need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear vinyl tubing to fit bleeder nipples
  • Catch bottles or jars
  • Brake bleeder wrench or properly sized open-end wrench
  • Disposable gloves & safety glasses
  • Clean rags and a fluid transfer pump or turkey baster
  • Torque wrench (for caliper bolts if you remove any parts)
  • Optional: hand vacuum bleeder or pressure bleeder for single-operator convenience

Preparation

  1. Park the ATV on level ground, set the parking brake, put the transmission in park/neutral and turn off the engine. Use wheel chocks.
  2. Clean the top of each master cylinder reservoir caps before opening to prevent contamination. Remove caps and diaphragm/foam inserts carefully, leaving caps nearby but not inverted in fluid.
  3. Top each reservoir with fresh DOT 4 fluid to the specified level; do not overfill. Keep the cap off until bleeding is complete.
  4. Identify bleed nipples: front calipers (left & right) and rear caliper. Fit clear tubing onto each nipple and run into a catch bottle partly filled with a small amount of fresh fluid to prevent air re-entry.

Bleeding order & recommended method

Use the following order to minimize air in lines: farthest wheel from a master cylinder first, then closer. For Renegade 800R X:

  1. Front passenger-side caliper (right front)
  2. Front driver-side caliper (left front)
  3. Rear caliper

Recommended method: pressure or vacuum bleeder for a single operator, or two-person manual pump method. Both are outlined below.

Method A – Pressure bleeder (preferred single-operator)

  1. Attach pressure bleeder to the front master cylinder reservoir following the bleeder tool instructions. Pressurize to 5-8 psi (do not exceed tool recommendations or reservoir rating).
  2. Open the bleeder nipple on the far front caliper slightly, allow fluid to flow into tubing until clear fluid with no air bubbles appears. Close nipple and torque to specification if applicable (hand-tight plus small fraction — typically 8-12 Nm on bleeder screws; check service manual for exact torque).
  3. Repeat for the near front caliper, then the rear caliper. Keep the master reservoir topped to prevent running dry.
  4. When all calipers are clear, release pressure bleeder, reinstall reservoir diaphragms & caps, clean any spills, and test lever/pedal firmness with engine off. Repeat if a spongy feel remains.

Method B – Two-person manual pump

  1. Person A sits on the ATV and pumps the brake lever/pedal slowly to build firm pressure, then holds steady pressure.
  2. Person B opens the far caliper bleeder for a short burst to let fluid out, then closes it before Person A releases the lever. Do not let the master reservoir go below the minimum level.
  3. Repeat pumping cycles until clear, bubble-free fluid flows from that caliper, then move to the next caliper in the prescribed order.
  4. Finish with multiple firm lever/pedal checks to confirm no sponginess. Top reservoirs, reinstall caps, and wipe everything clean.

If you encounter stubborn air or a spongy pedal

  • Cycle bleeding more times, use a vacuum or pressure bleeder, or bench-bleed a replaced master cylinder if necessary.
  • Inspect for soft brake hoses, leaking caliper seals, or a damaged master cylinder if air returns after a short ride.
  • If ABS is present and air is trapped in the pump or modulators, dealer-level bleeding tools or an ABS cycle procedure may be required.

Tips, torque & safety reminders

  • Always use fresh, unopened DOT 4 fluid. Do not top up with old fluid.
  • Dispose of used fluid according to local regulations; do not pour it on the ground.
  • Protect painted surfaces & plastics. If fluid spills on paint, rinse immediately with plenty of water.
  • After bleeding, check caliper bolts & banjo fittings for correct torque. Caliper bolt torque values vary by model — if unsure, tighten to a moderate spec and verify with service data. Replace crush washers on banjo bolts if disturbed.
  • Test brakes at low speed in a safe area before returning to normal use.

Maintenance interval

For the Renegade 800R X, replace brake fluid every 2 years or sooner if contamination or moisture ingress is suspected. Inspect lines, pads, rotors & calipers during each service.

Common model-specific issues to watch for

  • Older Renegade machines can show caliper seal wear and piston corrosion if exposed to water crossings; inspect and rebuild calipers if seals leak or pistons bind.
  • Check reservoir diaphragms for deterioration — cracked diaphragms allow moisture contamination and should be replaced.
  • Owners who run their Renegade in wet, muddy conditions should bleed and inspect brakes more frequently.

Following this MotoSport procedure will restore a firm pedal/lever feel and ensure safe braking on your 2009 Can-Am Renegade 800R X. If you encounter persistent issues after thorough bleeding & inspection, contact a qualified technician.
