How to Bleed & Replace Brake Fluid on a 2018 Can-Am Renegade 1000R X MR

Shop parts for a 2018 Can-Am Renegade 1000R X MR ATV.

This MotoSport procedure is written for owners of the 2018 Can-Am Renegade 1000R X MR (MMY CAN_AM;REN1000RXM;2018). Follow this guide to safely drain, replace, and bleed the hydraulic brake fluid on your machine. Read all steps before starting and use proper PPE. This guide is proprietary to MotoSport and tailored to the Renegade 1000R X MR.

Tools & supplies

  • DOT 4 brake fluid (clean, unopened bottle)
  • Brake bleeder kit or clear tubing and a catch bottle
  • Wrenches for bleed nipples (open-end or flare nut, typically 8mm or 10mm)
  • Screwdrivers, pliers
  • Clean rags and brake cleaner
  • Shop jack or stands to safely support the ATV
  • Gloves and eye protection
  • Optional vacuum pump or pressure bleeder for faster, cleaner job

Important model notes for the 2018 Renegade 1000R X MR

  • The Renegade uses a DOT 4 hydraulic system. Do not mix DOT 4 with DOT 3 or DOT 5 (silicone) fluids.
  • Brake master cylinders are accessible but may be covered by body panels – remove panels carefully to avoid damaging fasteners or wiring.
  • Some Renegade models use a linked braking system between front and rear circuits; always bleed the entire system until clean fluid appears at every bleed port.
  • Brake lines on the X MR are routed for aggressive terrain use. Inspect lines, banjo fittings, and calipers for damage, corrosion, or leaks before reassembly.
  • If your machine is used in deep-water crossings, plan for more frequent fluid changes and thorough inspections following water exposure.

Preparation

  1. Park on level ground, block wheels, and remove the key. Support the ATV securely with jack stands so wheels can rotate freely.
  2. Clean the master cylinder reservoir area to prevent contamination. Remove the reservoir cap and diaphragm; keep exposure to air brief.
  3. Inspect brake lines, fittings & calipers. Replace any damaged components before proceeding. MotoSport recommends replacing rubber hoses older than five years or with visible cracking.

Drain & replace brake fluid (recommended full fluid change)

  1. Siphon or carefully pump out as much used fluid from the reservoir as possible using a clean syringe or turkey baster. Dispose of old fluid properly.
  2. Top the reservoir with fresh DOT 4 fluid to near the MAX mark. Keep the cap off but the reservoir covered lightly to reduce air ingress.
  3. Determine bleed sequence: start at the caliper or wheel furthest from the master cylinder and work to the nearest. For most Renegade layouts the typical sequence is: opposite rear wheel (if separate), then the other rear, then passenger-side front, then driver-side front — but confirm routing on your machine and follow the furthest-to-nearest rule.
  4. Attach clear tubing to the bleed nipple and submerge the other end in a small catch bottle partially filled with fresh brake fluid to prevent air reentry.
  5. Have an assistant slowly pump the brake lever/pedal several times and hold pressure (or use a pressure bleeder). While the lever/pedal is held, open the bleed nipple 1/4 turn to allow fluid and air to flow into the tubing. Close the nipple before the assistant releases pressure.
  6. Repeat pumping, holding, opening, and closing until the expelled fluid runs clear and free of bubbles. Keep the reservoir topped with fresh fluid throughout so it never runs dry.
  7. Move to the next bleed point and repeat the process following the chosen sequence.
  8. When all calipers are clear, perform several firm lever/pedal applications with the bleed nipples closed to check for a solid, consistent feel. If the lever is spongy, repeat bleeding until firmness returns.

Using a vacuum pump or pressure bleeder

  • Vacuum pump: attach to the bleed nipple, open nipple, and pull until clean fluid appears. Close nipple before removing pump. Repeat at each wheel, keeping reservoir full.
  • Pressure bleeder: pressurize the master cylinder reservoir per device instructions, then open bleed nipples in proper sequence until clear fluid exits. Pressure bleeding reduces the risk of drawing air into the reservoir but always watch reservoir level.

Final checks & torque

  • Ensure bleed nipples and any banjo bolts are tightened to manufacturer specification. If you do not have torque specs, snug securely then ensure no leaks; MotoSport recommends checking service manual torque values if available.
  • Replace reservoir diaphragm and cap, clean up any spilled fluid, and reinstall body panels removed earlier.
  • Test brakes at low speed in a safe area before full use. Confirm pedal/lever firmness and no pull or uneven braking.
  • Recheck bleed nipple tightness and fluid level after the first short ride; top to MAX if needed.

Safety & maintenance tips

  • Brake fluid is hygroscopic — it absorbs moisture over time. For reliable braking in demanding riding conditions change fluid every 12 months or sooner if exposed to contamination or water.
  • Never reuse drained fluid. Contaminated fluid damages seals and reduces boiling point.
  • Store brake fluid in an airtight container and discard any fluid left open more than a few months.
  • If you experience persistent brake fade, sponginess, or uneven braking after thorough bleeding, inspect calipers, master cylinder, and ABS components (if equipped) or consult a certified technician.

Performing a careful, complete fluid change and bleed will keep your 2018 Can-Am Renegade 1000R X MR stopping reliably. MotoSport recommends using OEM-quality parts and fresh DOT 4 fluid for best results.
