This MotoSport-exclusive guide walks you step-by-step through draining, flushing, and bleeding the brake system on a 2010 Can-Am Renegade 800R X XC. Follow these instructions carefully to restore firm brakes and keep your MMY ATV stopping safely on trail or race day.

What you need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear plastic hose and clean catch bottle
  • Wrenches to fit bleed nipples (open-end or flare), small adjustable wrench
  • Brake bleeder kit or vacuum pump (optional but speeds the job)
  • Syringe or turkey baster for reservoir removal
  • Clean rags, isopropyl alcohol, gloves, eye protection
  • Torque wrench for reassembly (recommended)

Model-specific notes for the 2010 Renegade 800R X XC

  • The Renegade 800R uses DOT 4 as the recommended fluid. Do not mix DOT 3/5.1 unless specified by replacement fluid manufacturer.
  • Front brake master cylinder/reservoir is at the handlebars; the rear master cylinder and reservoir are typically mounted near the frame under the seat or behind bodywork. Identify both reservoirs before starting.
  • There is no factory ABS on this MMY model to complicate bleeding; the system is hydraulic and uses conventional calipers and bleed nipples.
  • Brake fluid damages paint and plastics – mask surrounding surfaces and wipe spills immediately with isopropyl alcohol.
  • Inspect flexible hoses and calipers for leaks, cracks, or seized pistons while you're working; this model can show aged rubber lines if not previously replaced.

Preparation

  • Park on level ground, set parking brake, and remove ignition key. Secure machine on stands so wheels can turn freely.
  • Clean the top of each reservoir cap, then remove caps and rubber diaphragms. Keep debris out of reservoirs at all times.
  • Remove enough old fluid from each reservoir with a syringe or turkey baster until fluid level is low but not empty. Dispose of old fluid safely.
  • Top reservoirs with fresh DOT 4 so they don't run dry during bleeding.

Fluid replacement & bleeding order

Bleed the system in the sequence farthest from the master cylinder to the nearest. For this ATV that typically means:

  • Rear caliper first (if rear has its own master, bleed that system separately)
  • Then the front calipers: the caliper farthest from the master cylinder first, then the nearer caliper

Note: If your Renegade has independent front/rear master cylinders, treat each circuit separately and use the farthest-to-nearest rule for each circuit.

Bleeding procedure (two-person method)

  1. Attach clear hose to bleed nipple and place other end in a catch bottle partially filled with fresh fluid to prevent air re-entry.
  2. Have an assistant slowly squeeze and hold the brake lever or pedal. With lever/pedal held, open the bleed nipple about a quarter turn until fluid and air bubbles run into the bottle; close the nipple before your assistant releases the lever/pedal.
  3. Repeat pump-open-close cycles until only clear fluid with no air bubbles flows. Keep reservoir topped up between cycles to avoid drawing air into master cylinder.
  4. When clear, tighten bleed nipple snugly, wipe any fluid, replace reservoir diaphragm and cap temporarily, and move to the next caliper.

Bleeding procedure (single-person vacuum or pressure method)

  1. Connect vacuum pump to the bleed nipple, or use a pressure bleeder on the reservoir per tool instructions.
  2. Open bleed nipple and draw fluid until clear with no bubbles. Keep reservoir level sufficient to avoid air intake.
  3. Close nipple, move to next wheel, and repeat until all circuits show clear fluid.

Finishing steps

  • Top reservoirs to the correct level, reinstall diaphragms and caps, and torque any fasteners to factory or service manual values where provided.
  • Clean any spilled fluid from paint and components immediately.
  • Check lever and pedal firmness by slowly applying pressure; a firm, non-spongy feel indicates successful bleeding.
  • Test ride slowly in a safe area, making repeated stops to verify braking performance. Recheck reservoir levels after the first short ride.
  • Dispose of old fluid per local environmental rules.

Troubleshooting & tips

  • Persistent spongy brake feel: likely still air in the system, a leaking fitting, or a collapsed hose. Recheck bleed points and inspect hoses.
  • If a caliper piston is slow to retract or seized, remove the caliper and service pistons/seals or replace the caliper.
  • Always replace brake line banjo bolts and crush washers if damaged or if you loosen lines for service.
  • Avoid prolonged exposure of DOT fluid to air – it absorbs moisture which reduces boiling point and can corrode components.

How often to replace brake fluid

MotoSport recommends replacing brake fluid every 1-2 years depending on use and storage conditions, or sooner if you suspect contamination or feel performance deterioration. Aggressive riding, mud, and water crossings accelerate fluid degradation on trail machines.

Final safety reminders

  • Never ride with a soft or untested brake system. If brakes are not firm after multiple bleeding attempts, stop and consult a qualified technician.
  • Wear eye protection when opening the hydraulic system. Brake fluid is toxic and corrosive to finishes.
