This MotoSport-exclusive guide walks you step-by-step through flushing and bleeding the brake system on a 2012 Can-Am Renegade 800R X XC. Follow these instructions carefully to restore braking performance, avoid contamination, and protect the ABS components and master cylinders unique to this model.

Safety & preparation

  • Work on a level surface, engine off, key removed, and parking brake applied.
  • Use DOT 4 brake fluid only. The Renegade 800R X XC is specified for DOT 4; using DOT 3 or silicone fluids can cause failure.
  • Wear gloves and eye protection; brake fluid damages paint and plastics.
  • Have a clean catch container, clear tubing to fit bleeder nipples, a wrench set, turkey baster or fluid syringe, clean rags, and fresh DOT 4 fluid.
  • Block wheels and support the machine on a proper jack or stands if wheel removal is required.

Model notes — what to know about the 2012 Renegade 800R X XC

  • The 800R X XC uses a hydraulic system with combined front/rear braking layout; it may have ABS or electronic braking aids depending on trim and region. Confirm if your unit has ABS components before aggressive flushing procedures.
  • The front calipers are dual-piston design; rear is single or dual depending on configuration. Caliper piston sticking is common after long service intervals; inspect pistons and pads for uneven wear while bleeding.
  • ABS modulator units can trap old fluid. If the bike has ABS, extra cycling steps may be required (see ABS section below).
  • Master cylinders: inspect resevoir cap diaphragm and fluid level sensors. Replace cracked diaphragms and clean the cap to prevent contamination ingress.

Step 1 – Access fluid reservoirs and inspect

  • Locate the front and rear brake fluid reservoirs. Clean around caps to prevent dirt falling in. Remove caps and diaphragms; leave caps loose to prevent vacuum during bleeding.
  • Note fluid color. Dark or contaminated fluid indicates a full replacement is needed rather than top-up.

Step 2 – Remove old fluid from reservoirs

  • Use a turkey baster or syringe to remove as much old fluid from each reservoir as possible. This reduces contamination pushed through the system.
  • Refill with fresh DOT 4 to the recommended level mark. Do not overfill.

Step 3 – Bleed order and general method

Follow this order unless service manual specifies otherwise: farthest caliper from the master cylinder first, working toward the closest. For most Renegade layouts that means rear caliper first, then right front, then left front. If unsure, bleed rear then both fronts.

  • Attach clear tubing to the bleeder nipple and place the other end in a catch bottle partially filled with clean brake fluid to avoid air re-entry.
  • Have an assistant slowly depress the brake lever/pedal and hold pressure while you open the bleeder about 1/4 turn. Fluid and air will flow into the tube.
  • Close the bleeder before the assistant releases the lever/pedal. Repeat until no bubbles appear and fluid runs clear.
  • Keep reservoir topped with DOT 4 during the entire process to avoid drawing air into the system.

Step 4 – Torque & inspect bleeder parts

  • Bleeder nipple torque: snug to manufacturer spec; do not overtighten. Replace bleeder screws or copper crush washers if corroded or leaking.
  • Inspect hoses for swelling or deterioration; replace if soft or cracked.

ABS-equipped units — extra steps

  • If your Renegade has ABS, the modulator can trap air. After conventional manual bleeding, cycle the ABS pump per the service procedure to purge internal passages. If no factory scan tool is available, perform several ignition cycles and apply firm steady brake pressure while an assistant operates the brake to encourage trapped air out, then repeat bleeding at each caliper.
  • If ABS symptoms persist (pulsation, spongy pedal, warning lights), professional scan/bleed with a dealer-level tool may be necessary.

Step 5 – Full fluid replacement (recommended every 1-2 years)

  • For a complete fluid change, perform the bleed sequence until the fluid exiting is new and the reservoir contains only fresh DOT 4. Replace the reservoir diaphragm and cap if deteriorated.
  • Dispose of used brake fluid properly; it is hazardous waste.

Step 6 – Final checks

  • After bleeding, ensure bleeder screws are tight and free of leaks. Reinstall reservoir diaphragms and secure caps.
  • Check brake lever and pedal for firm feel; free play should be normal and brakes should engage without sponginess.
  • Test ride slowly in a safe area to confirm braking performance. Recheck fluid level after initial ride and after 24 hours of use.

Troubleshooting & common problems

  • Spongy brake feel after bleeding: likely air remains, repeat bleeding and ensure reservoir never runs low.
  • Brake drag after bleeding: check caliper slide pins, piston return, and correct pad clearance. Clean and lubricate slide pins with proper brake grease.
  • Persistent ABS light: requires diagnostic check and possibly an ABS-specific bleed with scan tool.

Maintenance tips specific to the 2012 Renegade 800R X XC

  • Service interval: replace brake fluid every 12-24 months depending on riding conditions. Wet, muddy, or salty environments require more frequent changes.
  • Keep a small supply of DOT 4 and a spare reservoir diaphragm in your tool kit during off-road trips.
  • Inspect caliper pistons and pads when changing fluid; replace pads if material is low or glazing is present.
  • Record service dates and mileage; the 800R has robust hardware but benefits from proactive hydraulic maintenance to avoid costly caliper or ABS unit work.

Parts & recommended spares

  • DOT 4 brake fluid (sealed bottle)
  • Bleeder screw replacement set and crush washers
  • Master cylinder reservoir diaphragm and cap gasket
  • Caliper rebuild kits if pistons are corroded

Performing a careful bleed and fluid replacement restores braking consistency and protects the 2012 Can-Am Renegade 800R X XC's hydraulic components. When in doubt about ABS-related procedures or if you encounter persistent issues, consult a qualified technician.
