Shop parts for a 2020 Kawasaki Brute Force 750 4X4i EPS ATV.
This MotoSport guide walks you through a safe, reliable brake fluid change and bleed for the 2020 Kawasaki Brute Force 750 4X4i EPS. Follow every step, wear safety gear, and work on a cool, level machine.
What you need
- DOT 4 brake fluid (do not mix DOT 3/5 unless manufacturer permits)
- Clean rags, gloves, eye protection
- Clear plastic tubing that fits bleeder nipples
- Catch bottle (partially filled with fresh fluid to prevent air intake)
- Wrench for bleeder nipples (typically 8mm or 10mm)
- Syringe or turkey baster (optional) to remove old fluid from reservoirs
- Assistant (recommended) or a quality vacuum/pressure bleed tool
- Service manual or torque wrench for reservoir cap and caliper hardware specs
Model notes specific to the 2020 Brute Force 750 4X4i EPS
- Brake type: hydraulic dual front disc, single rear disc. No factory ABS on this MMY. EPS refers to Electronic Power Steering only; it does not alter the brake system.
- Master cylinders: separate front and rear reservoirs. Service each circuit independently.
- Reservoir location: front brake reservoir mounted near the right handlebar master cylinder; rear reservoir near left handlebar/master or distinct rear master depending on trim. Verify visually before starting.
- Recommended fluid: DOT 4. Kawasaki specifies DOT 4 for many of its ATVs; confirm on your unit's reservoir cap labeling.
- Protect painted plastic and electrical connectors from spilled fluid — brake fluid can damage paint and some plastics.
Preparation
- Park on level ground, set parking brake, and place the machine on a stable stand so wheels are off the ground if possible.
- Clean around each reservoir cap before opening to avoid contamination.
- Inspect lines, calipers, hoses, and connections for damage or leaks; replace damaged parts before bleeding.
Bleed order
Always start with the caliper farthest from the master cylinder and work toward the closest. For the Brute Force 750 this typically is:
- Rear caliper (farthest)
- Right front caliper
- Left front caliper (closest)
Step-by-step procedure – manual pump bleed (with assistant)
- Remove reservoir caps and diaphragms one at a time, keeping dirt out. Do not let the reservoir run dry during the process.
- Top reservoir with fresh DOT 4 fluid to the maximum mark.
- Attach clear tubing to the bleeder nipple and submerge the other end in a small catch bottle containing some fresh fluid.
- Have your assistant slowly pump the brake lever/pedal 3–5 times and then hold it firmly applied.
- Open the bleeder nipple about a 1/4 turn. Fluid and air bubbles will flow into the tubing. Close the nipple before the assistant releases the lever/pedal. Repeat until clear, bubble-free fluid comes out.
- Keep the reservoir topped up between cycles to avoid drawing air into the master cylinder.
- When the flow is clear, tighten the bleeder to spec (hand-tight plus a small fraction; do not over-torque). Wipe any spilled fluid immediately.
- Repeat for the next caliper in the sequence.
- After finishing all calipers, pump the lever/pedal several times to ensure firm feel. Check reservoir level and top to the max line, then reinstall caps and diaphragms securely.
Optional — vacuum or pressure bleeding
If you have a hand vacuum pump or pressure bleeder, you can perform a single-person bleed. Use the same caliper order and keep the reservoir topped. Vacuum bleeding attaches to the bleeder nipple and draws fluid out while you cycle the lever; pressure bleeding pressurizes the reservoir and forces fluid through the system. Follow your tool manufacturer instructions, and never exceed recommended pressure when using a pressure bleeder.
Complete fluid flush
To fully replace old fluid, repeat the bleed process until fresh, clear fluid is apparent at each caliper and the reservoir. Typically a full flush requires multiple reservoir refills and bleeding cycles. Dispose of old fluid per local regulations.
Common problems & troubleshooting
- Spongy lever/pedal after bleeding: likely air remains. Re-bleed the circuit, ensuring the reservoir never runs low.
- No fluid flow: check for clogged lines, seized caliper pistons, or closed bleeder nipple. Inspect and free pistons if needed.
- Brake drag after bleeding: caliper pistons may be sticking. Clean and lubricate slide pins or rebuild caliper as required.
Final checks
- Road-test at low speed in a safe area to confirm firm brake feel and proper function.
- Inspect for leaks after the test ride and re-check reservoir levels.
- Record the service date and fluid type in your maintenance log. Kawasaki-recommended intervals: inspect fluid yearly and replace every 1–2 years depending on use and contamination risk; adjust for heavy or wet use.
