This MotoSport-exclusive guide walks you through safely flushing and bleeding the hydraulic brakes on a 2022 Yamaha Kodiak 700 4X4 EPS IRS. Follow every step and observe safety precautions. If you’re not confident working on brake systems, have a qualified mechanic do the job.
What you need
- DOT 4 brake fluid (Yamaha recommends DOT 4 — use only fresh, unopened fluid)
- Clear tubing that fits bleeder nipples
- Catch bottles or jars and disposable rags
- Wrench set sized for bleeder nipples and banjo bolts
- Torque wrench (for banjo bolt reinstallation)
- Vacuum/pressure bleeder (optional but speeds up process)
- Brake-clean spray and gloves/eye protection
- New crush washers for banjo bolts (recommended)
- Jack and stands or ramps to lift wheels safely
Safety & prep
- Work on a level surface with the engine off and key removed. Set parking brake and block wheels.
- Wear gloves & eye protection. Brake fluid damages paint & plastics — protect painted surfaces and clean spills immediately.
- Keep the brake fluid reservoir cap closed except when adding fluid to avoid contamination. Never reuse opened fluid left exposed to air.
Model-specific notes for the 2022 Kodiak 700 4X4 EPS IRS
- The Kodiak 700 EPS IRS uses a hydraulic disc system without factory ABS; the master cylinder reservoir is accessible but tucked near the handlebar area for front braking and a rear circuit that may share the same reservoir. Confirm reservoir layout on your machine before starting.
- EPS (electric power steering) systems can affect steering feel after brake service. Cycle the steering through full lock left to right before bleeding to ensure lines and fittings aren’t kinked.
- Inspect caliper mounting bolts, banjo bolt washers, and lines for chafing around the IRS linkages & swingarm areas common on Kodiak models. Replace damaged lines or worn hardware.
- Use new crush washers on brake line banjo bolts when reassembling to prevent leaks.
General bleeding strategy
Bleed in sequence from the wheel farthest from the master cylinder to the closest. On most Kodiak 700 setups that means: rear passenger, rear driver, front passenger, front driver. If your machine has a separate rear and front circuit, bleed the circuit with the most remote caliper first within that circuit. Refer to the master cylinder location visually and confirm the furthest caliper before starting.
Step-by-step: Complete fluid replacement
- Remove reservoir cover and diaphragm. Clean around the cap to prevent dirt entering the system. Siphon or wick out old fluid from the reservoir until low but not empty.
- Top reservoir with fresh DOT 4 fluid. Keep cap loosely on to avoid contamination but allow air escape during bleeding if using manual pump method.
- Raise and secure the ATV so wheels hang or are clear to move the calipers freely. Remove wheels only if needed for caliper access.
- Locate bleeder screws on each caliper and fit clear tubing over the nipple, routing into a catch bottle partially filled with clean brake fluid to avoid air re-entry.
- If using a vacuum or pressure bleeder: attach to reservoir or master cylinder per tool instructions and pressurize to the recommended safe level. If manual bleeding, have an assistant sit on the seat and slowly pump the brake lever/pedal several times, then hold pressure.
- Open the bleeder screw on the farthest caliper ~1/4 turn. Let fluid flow until the stream is clean and free of bubbles. Close bleeder before the assistant releases the lever/pedal if manual method. Repeat until no air appears, topping the reservoir frequently to prevent it from running dry.
- Proceed to the next furthest caliper after the previous one is confirmed bled. Repeat the open-pump-close cycle on each caliper in sequence. Always keep the reservoir filled between cycles.
- Once all calipers show clean, bubble-free fluid, perform final flush cycles on each caliper until the reservoir level is stable and fluid coming from each screw is clear.
- After final bleeding, tighten bleeder nipples to spec (snug; do not over-torque). If you removed banjo bolts, install new crush washers and torque banjo bolts to the specified value in the service manual.
- Top the reservoir to the correct level, re-install diaphragm and cap, clean any spilled fluid, and reinstall wheels if removed. Lower the vehicle to the ground.
- Check pedal/lever firmness — leverage should be firm and not spongy. If spongy, repeat bleeding. Inspect for leaks at banjo fittings, bleeder screws, and hose connections.
- Road-test gently at low speed to confirm braking performance. Recheck fluid level and hardware after the first short ride.
Troubleshooting & tips
- If you encounter persistent air or a soft pedal, warm the system by riding gently then rebleed; trapped air can cling to caliper pistons until warmed.
- Do not mix DOT 3 and DOT 4. If system previously had DOT 3, a full flush to DOT 4 is acceptable but ensure all old fluid is removed.
- Replace rubber hoses older than recommended service interval — aging hoses can balloon under pressure and cause soft feel even after correct bleeding.
- Keep a clean workspace — contaminated fluid accelerates component wear.
Maintenance interval recommendation
Replace brake fluid every 2 years or sooner if you notice moisture contamination, degraded brake feel, or after heavy use in wet/muddy conditions. Regular inspection of lines, calipers, and fittings is especially important on the Kodiak 700 because IRS linkage motion can rub hoses if routing or clamps are compromised.
Final checks
- Confirm no leaks, secure reservoir cap, and dispose of used fluid per local regulations.
- Record the service date and type of fluid used in your maintenance log for future reference.
If anything feels uncertain during the process, stop and consult a dealer or certified technician to avoid risking brake failure.
