Scope: Step-by-step, model-specific procedure for flushing and bleeding the brake system on a 2020 Yamaha Kodiak 700 4X4 EPS IRS. This guide is proprietary to MotoSport and geared to technicians and owners who want a reliable, safe fluid replacement.
What you need
- DOT 4 brake fluid (Yamaha recommends DOT 4; never mix with DOT 3 or silicone fluids)
- Clear plastic tubing sized to fit caliper bleed nipples snugly
- Catch bottle for old fluid
- Wrench for bleed nipples (typically 8 mm or 10 mm depending on caliper hardware)
- Turkey baster, syringe, or vacuum pump for reservoir/drain
- Clean rags, drip tray, gloves & eye protection
- Torque wrench for reassembly (when needed)
Model notes – 2020 Kodiak 700 EPS IRS
- The master cylinder reservoir is mounted on the handlebar near the right hand control. Keep the ATV upright and level while working to avoid trapping air against the reservoir cap.
- EPS (Electronic Power Steering) power draw and battery condition can affect electric-start models during long bleed operations; keep the battery charged or the engine running (in neutral) per safety guidelines so power-assisted components remain functional.
- IRS rear brakes are independent; calipers are located at each rear wheel hub. Brake lines are relatively short — follow the "farthest-first" bleeding order based on the master cylinder position.
- Use only DOT 4 and replace any soft, swollen rubber hoses found when inspecting lines. Corrosion or damaged bleeder valves should be replaced before proceeding.
Safety & preparatory steps
- Work on a level surface with the ATV secured in gear or on a stand with the parking brake engaged if applicable.
- Wear gloves and eye protection. Brake fluid damages paint & plastics; protect painted surfaces with rags.
- Clean the reservoir cap area before opening to prevent contamination.
- Keep the reservoir cap loosely installed between operations to prevent debris entry while allowing pressure relief.
Bleed & replace procedure
- Baseline inspection: Check pads, rotor condition, hoses, and bleed nipple condition. Replace worn parts first.
- Remove old fluid from reservoir: Use a syringe or turkey baster to remove as much old fluid as possible from the handlebar reservoir. Dispose of fluid properly.
- Top up reservoir: Refill with fresh DOT 4 to the MAX mark.
- Determine bleeding order: Locate the master cylinder (handlebar). Bleed the wheel farthest from the master cylinder first, then proceed to the next farthest. Typical sequence for Kodiak 700 (handlebar MC): rear passenger side (if applicable), rear driver side, front passenger side, front driver side. Confirm orientation on your machine; the rule is farthest → nearest.
- Fit tubing: Push clear tubing onto the bleed nipple and place the other end into a catch bottle partially filled with fresh fluid (to keep air out).
- Crack bleed nipple: With a wrench, open the bleed nipple about 1/4 turn. Have an assistant slowly squeeze the brake lever (or pedal if bleeding rear) to push fluid and air out. For handlebar master cyl, use gentle repeated strokes; do not fully depress and hold for long periods to avoid heat buildup.
- Pump & close: While an assistant holds the lever down, close the bleed nipple, then release the lever. Repeat pumping until no air bubbles appear in the tubing and fluid flows clear. Keep the reservoir topped up between cycles to avoid drawing air into the system.
- Repeat for each wheel: Follow the bleeding order until all four calipers deliver clear fluid with no bubbles and firm lever/pedal feel.
- Final flush: Once all calipers are bled, drain and refill the reservoir completely with fresh DOT 4, then repeat a final bleed pass on each caliper in the established order to ensure fresh fluid throughout.
- Torque & clean: Tighten bleed nipples to the correct snug specification (do not overtighten). Wipe all components clean of fluid and check for leaks.
- Test ride: With wheels down and ATV on stable ground, start engine (if required for EPS) and perform low-speed brake checks in a safe area to confirm firm response before normal operation.
Tips for a robust bleed
- Use a one-way valve kit or vacuum bleeder for single-operator convenience and cleaner results.
- If the lever feels spongy after bleeding, repeat the process — trapped air is the usual cause.
- Never let the master cylinder reservoir run dry during bleeding — doing so will reintroduce air into the system.
- Label and replace any discolored or contaminated fluid lines and hardware.
Maintenance intervals & disposal
- Replace brake fluid every 1-2 years or sooner if the fluid appears dark or contaminated. Severe use or water ingress shortens service life.
- Dispose of old brake fluid at a proper hazardous waste or recycling center; do not pour down drains.
Common Kodiak owner pitfalls
- Assuming lever feel equals good fluid quality — old fluid can still produce firm brakes until moisture causes accelerated wear or boiling under heavy use.
- Neglecting EPS battery state during prolonged bleeding operations — low voltage can affect EPS behavior; maintain charge.
- Overfilling the reservoir — fluid expands with heat; keep within the MAX line and check level after a test ride.
Following this procedure will give you a complete, safe brake fluid replacement specific to the 2020 Yamaha Kodiak 700 4X4 EPS IRS. If you encounter seized bleed nipples, corroded lines, or persistent sponginess after multiple bleeds, consult a qualified technician.
