How to Bleed & Replace Brake Fluid on a 2019 CFMOTO CFORCE 600

Shop parts for a 2019 CFMOTO CFORCE 600 ATV.

This MotoSport-exclusive how-to walks you through flushing and bleeding the hydraulic brake system on a 2019 CFMOTO CFORCE 600. Follow these steps to restore firm pedal/lever feel and remove moisture-contaminated fluid. Read each step before you begin, work in a clean, well-ventilated area, and observe all safety cautions.

What you need

  • DOT-specified brake fluid (use the type specified in your owner’s manual; most CFORCE 600 applications call for DOT 4)
  • Clear hose that fits bleeder nipples
  • Brake-fluid catch container and disposable bottle(s)
  • Clean funnel and lint-free rags
  • Wrenches sized for bleeder screws (usually 8mm or 10mm)
  • Rubber gloves & eye protection
  • Assistant or a vacuum/pressure bleeder (recommended for consistent results)
  • Torque wrench for reassembly (if you remove calipers)

Model notes for the 2019 CFORCE 600

  • The CFORCE 600 uses hydraulic disc brakes front & rear; the front master cylinder is on the handlebar; the rear master cylinder is positioned near the foot controls. Bleeder screws are on each caliper.
  • There is no factory ABS system on most 2019 CFORCE 600 trims — bleeding is conventional and done per-caliper.
  • Brake lines are routed for off-road use; inspect lines and fittings for chafing or damage before bleeding. Replace corroded bleeder screws or damaged hoses with OEM-equivalent parts available at MotoSport.

Preparation

  • Park on a level surface, secure the machine, and remove the key.
  • Raise the wheels if needed so calipers are accessible and wheels can turn freely.
  • Clean around all fluid reservoirs, caps, and bleeder screws to prevent contamination.
  • Remove the master cylinder reservoir cap(s) diaphragm & cap, then place a clean funnel or a protective cover to keep dirt out.
  • Check and note current fluid level; don’t let reservoirs run dry during bleeding (introduces air).

Bleeding strategy

Always bleed from the caliper farthest from the master cylinder to the nearest. On most CFORCE layouts that means: rear caliper(s) first, then front caliper(s). If there are two front calipers fed by one master, finish with the front calipers nearest the master last. If you’re unsure, start at the rear and finish at the front.

Manual (two-person) bleeding procedure

  1. Top off the master cylinder reservoir with fresh DOT fluid.
  2. Have your assistant slowly pump the brake pedal or lever several times and hold pressure while you open the bleeder screw on the target caliper about a 1/4 turn. Attach clear hose from bleeder nipple to catch bottle.
  3. Fluid and air will flow into the catch bottle. Close the bleeder before the assistant releases the pedal/lever.
  4. Repeat pump, hold, open, close until clear fluid free of air bubbles flows. Keep reservoir level topped up between cycles.
  5. Move to the next caliper following the furthest-to-nearest order, repeating steps above.
  6. After the final caliper, pump the brake/lever firmly and check for firm, consistent pressure. Tighten bleeder screws to manufacturer snugness. Wipe any spills immediately.

Pressure or vacuum bleeder method

  • Follow the tool manufacturer’s instructions. Pressurize the master reservoir or attach vacuum to bleeder nipples to pull fluid through until clear, bubble-free fluid appears at each caliper.
  • Keep reservoir topped and check seals during the process.

Flushing the system completely

To fully replace old fluid, continue bleeding until the fluid at the master reservoir is the new fluid color and free of contamination. If old fluid is heavily discolored or brown, multiple reservoir refills & bleeding passes may be necessary.

Final checks & cleanup

  • Torque bleeder screws and any removed fittings to OEM specs if available. If you removed calipers to improve access, torque caliper mounting bolts to spec and verify rotor alignment.
  • Replace reservoir diaphragm & cap. Clean all fluid residue from paint, plastics, and brake components with water & mild detergent — brake fluid is corrosive to paint.
  • Test brakes at low speed in a safe area before normal riding. Confirm pedal/lever feel and stopping performance.
  • Properly dispose of old brake fluid per local regulations.

Warnings & tips

  • Never mix different types of brake fluid (DOT 3 vs DOT 4) unless acceptable per your owner’s manual. Mixing can degrade boiling point and performance.
  • Never let the reservoir run dry — doing so will introduce air and require repeating the entire bleed.
  • Brake fluid will damage paint & plastics; protect surfaces and clean spills immediately.
  • If you encounter persistent sponginess after bleeding, inspect master cylinders, calipers, hoses, and fittings for internal leaks, soft hoses, or master cylinder seal failure. Replace suspect components.
  • Keep a spare set of bleeder screws and banjo bolts on hand if rusted or rounded hardware is present on your CFORCE 600.

Perform routine brake inspections and fluid changes every 1-2 years depending on use & environment to maintain safe braking performance on your CFORCE 600.
