This guide is MotoSport's proprietary procedure for flushing and bleeding the hydraulic brakes on a 2016 Can-Am Renegade 850 X XC (MMY CAN_AM;REN850XXC;2016). It covers recommended fluid type, preparation, bleed sequence, techniques, and model-specific notes owners should know. Follow all safety precautions and local disposal laws for used brake fluid.

Overview & fluid spec

The Renegade 850 X XC uses hydraulic disc brakes. Use DOT 4 brake fluid unless the owner's manual for your specific unit indicates otherwise. DOT 4 is strongly recommended for this model because of its higher boiling point compared to DOT 3. Do not mix DOT 5 (silicone) with DOT 3/4. Brake fluid is hygroscopic — replace it every 1-2 years or sooner if contaminated or if soft, spongy pedal/lever feel develops.

Tools & materials

  • DOT 4 brake fluid (fresh, sealed bottle)
  • Brake bleeder wrench or box wrench to fit bleed nipples (usually 8mm or 10mm)
  • Clear plastic tubing to fit bleed nipples
  • Catch bottle with one-way valve or a clean container and check valve tubing
  • Vacuum bleeder or pressure bleeder (optional but recommended)
  • Assistant (if not using a pressure/vacuum bleeder)
  • Cotton rags, brake parts cleaner, rubber gloves, safety glasses
  • Torque wrench for caliper mounting bolts (if removed)
  • Jack and stands or ramps for safe wheel access

Preparation

  • Work on a level surface, engine off, key removed. Place ATV in park and engage parking brake.
  • Clean around reservoirs and bleed nipples to prevent contamination.
  • Identify master cylinder reservoirs: the Renegade 850 X XC may have separate reservoirs or a split master cylinder for front/rear circuits. Confirm which reservoir serves which calipers before beginning. Top up reservoirs to the MAX line with fresh DOT 4 fluid and keep the cap loosely installed to prevent debris from entering.
  • Protect painted surfaces from spilled fluid — DOT 4 will damage paint.

Bleed sequence

Bleed the brake circuit farthest from the master cylinder first and work toward the closest. Typical sequence for the Renegade 850 X XC:

  1. Rear passenger-side caliper (farthest)
  2. Rear driver-side caliper
  3. Front calipers left/right (or as routed from the master cylinder; if two separate master circuits exist, bleed each circuit separately starting farthest first)

Step-by-step: manual (two-person) method

  1. Raise ATV safely so the wheel with the caliper you're bleeding is off the ground, if needed.
  2. Remove caliper inspection covers if needed to locate bleed nipple. Fit a clear tube over the nipple and route into the catch bottle. Keep the hose filled with fluid to avoid air drawback.
  3. Have an assistant slowly apply steady pressure to the brake lever/pedal until it is near firm (do not hold to the floor). While held, open the bleed nipple about 1/4 turn to let fluid and air out. Close nipple before the assistant releases the lever/pedal.
  4. Repeat: pump lever/pedal, hold, open nipple, close nipple before release, and top up reservoir after each cycle to avoid drawing air into the master cylinder.
  5. Continue until clear fluid with no visible bubbles exits the bleed hose. Tighten bleed nipple to spec snug (do not over-torque) and wipe any spilled fluid.
  6. Move to the next caliper in sequence and repeat. Keep reservoir level between MIN and MAX throughout.
  7. After final bleed, ensure all nipples are tightened, clean the area, and test lever/pedal for firm feel with ATV lifted off stands and wheels spun to check binding.

Step-by-step: using a pressure or vacuum bleeder

  1. Attach the pressure bleeder to the master cylinder reservoir or connect the vacuum pump to the bleed nipple per tool instructions.
  2. If using pressure on the reservoir, apply low pressure (typically 10-15 psi) and open the farthest bleed nipple; allow fluid to flow until clear and bubble-free. Close nipple and move on to next caliper.
  3. Vacuum bleed each caliper in sequence by connecting the hose to the bleed nipple and operating the vacuum pump while occasionally topping off the master reservoir.
  4. Pressure bleed is faster and reduces the chance of introducing air at the master cylinder; always monitor reservoir level closely.

Finishing checks

  • Clean all fittings and ensure bleed nipples are properly seated and torqued to spec.
  • Restore any removed wheels or components and torque wheel fasteners to spec.
  • Operate the brake lever/pedal several times to confirm firm, consistent feel. With the engine off, ensure there's no lever/pedal sinking under constant pressure which could indicate a leak or internal master cylinder issue.
  • Check for leaks at calipers, lines, and master cylinder. Recheck reservoir level and cap it securely.
  • Test ride cautiously at low speed to confirm braking performance before returning to normal use.

Model-specific notes for the 2016 Renegade 850 X XC

  • Some 2016 Renegade 850s have separate front and rear circuits or integrated ABS components on select trims. If your machine has a traction control or ABS module, do not open or disturb hydraulic module fittings unless you are experienced; follow the manual for ABS-specific bleeding procedures, as trapped air in modules can be harder to remove.
  • Reservoir locations are on the handlebar master cylinder for the front and near the rear brake master cylinder for the rear. Confirm which reservoir feeds which calipers before starting so you maintain the proper circuit fill and sequence.
  • OEM brake lines and calipers on this model are robust, but inspect rubber hoses for cracking or swelling and replace any damaged lines. Replace soft, swollen hoses before bleeding for best results.
  • If the brake lever or pedal remains soft after careful bleeding, suspect a leaking caliper piston seal, master cylinder internal leak, or trapped air in ABS/modulator. Component replacement or dealer-level diagnostics may be required.
  • Use only DOT 4 fluid compatible with Can-Am seals. Avoid mixing fluid types and discard used fluid properly; it absorbs water and corrodes components if left in the system.

Safety & disposal

  • Wear eye protection and gloves. Brake fluid can harm painted surfaces — clean spills immediately with water and mild detergent.
  • Dispose of used brake fluid at a hazardous waste facility or according to local regulations. Do not pour it down drains or into soil.

Troubleshooting quick reference

  • Spongy lever/pedal after bleeding: repeat bleed, check for leaks, inspect hoses and master cylinder seals.
  • Brake fade or reduced braking: ensure fluid is fresh DOT 4 and not contaminated; check pads and rotors for wear.
  • Persistent air from one caliper: inspect caliper for leaking seals or piston problems; replace caliper if necessary.

Follow this MotoSport-specific procedure for reliable brake system service on your 2016 Can-Am Renegade 850 X XC. If you're not confident with hydraulic work, have a qualified technician perform the replacement and bleeding to ensure safety.
