This MotoSport guide walks you through safely replacing and bleeding the brake fluid on a 2019 CFMOTO CFORCE 800 XC EPS. It's written for owners who want a reliable, model-aware procedure to restore firm braking performance. Always consult your owner's manual for any model-specific cautions and confirm fluid type before starting.
What you'll need
- Brake fluid – DOT 4 recommended for CFORCE 800 models; confirm with your manual
- Clear tubing and a small catch bottle
- Wrenches to fit bleed nipples and banjo bolts
- Vacuum pump or pressure brake bleeder (optional, speeds process)
- Turkey baster or syringe for old fluid removal
- Rags, brake cleaner, and gloves
- Torque wrench (for reinstallation of banjo bolts if removed)
- Jack or stands to access wheels (if needed)
Model-specific notes for the 2019 CFORCE 800 XC EPS
- The CFORCE 800 XC EPS uses hydraulic disc brakes front and rear with sealed master cylinders. There is no factory ABS on this model year, so bleeding procedures are standard hydraulic bleeds.
- Factory-recommended fluid is DOT 4; do not mix silicone or mineral-based fluids.
- Brake lines on this machine run through tight chassis areas; inspect routing for chafing or damage while you have the system open.
- If your machine has aftermarket racks or guards, make sure you can access the master cylinder reservoirs and caliper bleed nipples before starting.
- After bleeding, check for leaks at banjo fittings and the master cylinder reservoir cap area — overtightening can damage crush washers, so replace crush washers if disturbed.
Safety first
- Work on a level surface with the engine off and key removed.
- Wear gloves and eye protection; brake fluid damages paint and is corrosive to skin.
- Keep the master cylinder reservoir topped off during bleeding to avoid air re-entry.
- Dispose of old brake fluid according to local regulations — do not pour down drains.
Overview of the bleed sequence
Always bleed starting from the caliper farthest from the master cylinder, then work toward the nearest. On the CFORCE 800 XC EPS that typically means: rear caliper first, then the two front calipers. If you have a two-circuit system with a separate front/rear master arrangement, follow the individual circuit order identified on your machine.
Step-by-step procedure
- Park the ATV and remove any panels blocking tank and reservoir access. Clean around the master cylinder reservoir caps to prevent contamination.
- Remove the reservoir cap(s) and diaphragm. Siphon out old fluid with a turkey baster until the reservoir is mostly empty and clean. Inspect fluid for dark color or contamination.
- Refill the reservoir with fresh DOT 4 brake fluid to the full mark. Keep the cap off but the area covered so you can top off during bleeding.
- Locate the bleed nipple on the caliper that is farthest from the master cylinder (usually the rear). Slip a clear tube onto the nipple and place the other end in a catch bottle partially filled with fresh fluid to prevent air ingestion.
- Have a helper slowly depress and hold the brake pedal or lever. Loosen the bleed nipple about a quarter to half turn to allow fluid and air to escape into the tubing. Tighten the nipple before the helper releases pressure. Repeat until clear, bubble-free fluid appears, topping the reservoir as needed.
- Move to the next-farthest caliper and repeat the squeeze-open-close routine. Continue until you've bled all calipers, finishing with the caliper nearest the master cylinder.
- If you're working alone, use a vacuum pump on the bleed nipple or a pressure bleeder on the reservoir to pull fluid through each caliper in the same far-to-near order.
- Once all calipers show clear fluid with no air, tighten all bleed nipples to spec (hand-tight plus a small turn; consult service manual for torque if available). Reinstall diaphragms and reservoir caps and wipe away any spilled fluid.
- Check pedal/lever feel — it should be firm. If softness remains, repeat bleeding sequence or suspect hidden air or a master cylinder issue.
- Inspect for leaks at banjo bolts, caliper fittings, and master cylinder. Replace any crush washers disturbed during the job and torque hardware to manufacturer specs.
Flushing the entire system
To fully replace all old fluid, continue bleeding each circuit until the fluid leaving the calipers matches the new fluid in color. Work methodically so the reservoir never runs low. A pressure bleeder speeds this and reduces the chance of introducing air.
Troubleshooting
- Spongy pedal after careful bleeding: check for air in lines, a leaking master cylinder, or swollen hoses. Replace hoses if they expand under pressure.
- Persistent leaks: tighten fittings, replace crush washers, and confirm banjo bolt torque. If leaking continues, inspect caliper seals and master cylinder for internal failure.
- Brake drag after bleeding: check caliper pistons for free movement and that pads retract; clean and lubricate slider pins where applicable.
Post-service checks
- Road-test the machine at low speed in a safe area to verify braking performance before normal use.
- Recheck fluid level after a short ride and inspect for leaks once warm.
- Record the service date and mileage for maintenance tracking.
Following this MotoSport procedure will help keep your 2019 CFMOTO CFORCE 800 XC EPS braking system reliable and safe. If you encounter uncertain damage or repeated bleeding failures, seek a qualified technician familiar with CFORCE models.
