This MotoSport guide walks you through safely replacing and bleeding the brake fluid on a 2025 CFMOTO CFORCE 800 Touring. Follow every step carefully, use the correct fluid, and observe safety precautions. If your machine is equipped with ABS, read the model notes below before proceeding.
What you’ll need
- DOT 4 brake fluid (confirm owner’s manual; CFORCE 800 Touring typically uses DOT 4)
- Clear vinyl tubing that fits bleeder nipples
- Catch bottle and a clean disposable container
- Hand vacuum or pressure brake bleeder (optional but speeds and cleans the job)
- Wrenches for bleeder nipples (usually 8mm or 10mm)
- Flat screwdriver and clean shop rags
- Gloves and eye protection
- Torque wrench (for caliper/bleeder hardware if you choose to torque after)
Model notes — 2025 CFMOTO CFORCE 800 Touring
- The CFORCE 800 Touring commonly uses a right-handlebar front master cylinder and a rear master cylinder routed to the rear caliper. Reservoirs are small; top-offs are easy but must be kept clean.
- Some Touring models may be fitted with ABS. If your ATV has ABS, do not attempt to cycle ABS modulator valves manually. ABS-equipped units can trap air in the modulator; follow OEM ABS bleed procedures or have a dealer run the ABS cycle with appropriate diagnostic gear after fluid replacement.
- Brake lines are routed under body panels and near the rear rack. Inspect routing & clips while panels are off — replace any damaged lines or fasteners sourced through MotoSport if needed.
- Use only fresh, sealed DOT 4 fluid. Do not mix brake fluid types. Brake fluid is hygroscopic — replacing every 12-24 months is recommended depending on use and conditions.
Safety & prep
- Work on a flat, stable surface. Chock wheels and secure the ATV to prevent movement.
- Covers or panels may need removal to access rear caliper and master cylinder; keep fasteners organized.
- Clean around the master cylinder reservoir cap before opening to avoid contamination.
- Protect paint & plastics — brake fluid will damage finishes. Wipe spills immediately.
Step-by-step fluid replacement & bleeding
1. Initial flush (reservoir drain)
- Remove the reservoir cap and diaphragm. Use a turkey baster or syringe to remove most old fluid from the reservoir.
- Wipe the reservoir clean with a lint-free rag. Refill to the max line with fresh DOT 4 fluid.
2. Bleed order and general rule
Bleed the calipers starting with the caliper farthest from each master cylinder to push air toward the master cylinder: typically rear caliper first (if single rear caliper), then the front calipers from the one farther from the master cylinder to the closer one. If you have a single front master cylinder with two calipers, bleed the furthest front caliper first.
3. Traditional two-person bleeding
- Attach clear tubing to the bleeder nipple on the caliper and route it into a catch bottle partially filled with fresh fluid (to prevent air re-entry).
- Have an assistant slowly squeeze the brake lever or pedal to the end of travel and hold.
- Open the bleeder nut about a quarter to half turn to let fluid and air escape into the tubing. Close the nut before the assistant releases the lever/pedal.
- Top off reservoir between cycles to keep fluid above the minimum line. Repeat until fluid runs clear and no air bubbles appear.
- Move to the next caliper in sequence and repeat.
4. One-person vacuum or pressure bleed
- Attach vacuum/pressure bleeding tool per the tool instructions. For vacuum systems, connect tubing to the bleeder nipple and pull fluid until clear fluid with no bubbles shows.
- Keep reservoir topped as needed. Vacuum/pressure tools reduce the chance of air re-entry and are recommended for cleaner, faster work.
5. Final checks
- Once all calipers are clear, pump the brake lever/pedal several times to confirm a firm feel. If spongy, repeat bleeding cycle.
- Clean bleeder nipples, torque to specification if known, and reinstall dust caps.
- Top the reservoir to the max line, reinstall diaphragm and cap, and secure panels removed for access.
- Dispose of used brake fluid responsibly — it’s hazardous waste.
Special considerations
- If you have ABS, after bleeding you may need to cycle the ABS by following the OEM procedure or have a shop run the self-test to purge air from the modulator. If you’re unsure, have MotoSport parts or a dealer perform the ABS-specific step.
- If brake feel does not improve after thorough bleeding, inspect master cylinder, calipers, hoses for internal leaks or collapsing hoses, and check for contaminated pads or rotors.
- Replace the master cylinder reservoir cap O-ring and bleeder screw seals if they show wear to ensure a clean seal.
Maintenance tips
- Record the date and mileage/hours when fluid was changed. Routine replacement every 12-24 months keeps contaminants and moisture out of the system.
- Inspect brake lines and fittings whenever you service brakes — replace any soft, cracked, or abraded lines.
- Use only new, sealed brake fluid bottles; store spare fluid in a cool, dry place and keep the bottle closed when not in use.
Perform a cautious test ride at low speed to verify braking performance before returning to normal use. If anything feels abnormal, stop and re-check the system or contact a professional technician.
