This MotoSport-exclusive guide walks you through safely flushing and bleeding the hydraulic brake system on a 2022 Yamaha Kodiak 700 4X4 IRS. Follow these steps carefully to restore firm braking and keep your Kodiak safe on trail or workdays.
What you need
- Yamaha-approved DOT 4 brake fluid (fresh, unopened)
- Clear tubing that fits bleed nipples
- Catch bottle for old fluid
- Box-end or flare nut wrench for bleed nipples (8 mm common; verify on your machine)
- Hand or vacuum brake bleeder (vacuum bleeder recommended for singleperson jobs)
- Clean rags, isopropyl alcohol for cleaning, gloves and eye protection
- Torque wrench for caliper/master cylinder mounting bolts (specs below)
- Jack or stands and wheel chocks if you need to remove wheels
Notes specific to the 2022 Kodiak 700 4X4 IRS
- The Kodiak 700 IRS uses hydraulic discs front & rear with one bleed nipple on each caliper. There is a single master cylinder/reservoir. DOT 4 is recommended for factory performance and heat resistance.
- Independent rear suspension means caliper access can be tighter on one side; a small wheel removal may be required for clearance.
- Caliper & master cylinder bolt torque: verify with service manual, but typical ATV caliper bolts are around 25-35 ft-lbs and reservoir/mount bolts 8-12 ft-lbs. When in doubt, consult the OEM torque table before final tightening.
- Avoid spilling brake fluid on painted surfaces. Brake fluid damages plastics & paint immediately; rinse with water and wipe thoroughly if a spill occurs.
- Inspect hoses, banjo bolts and copper crush washers for age or damage while you're servicing the system. Replace any suspect components.
Preparation
- Park on a level surface, secure with parking brake and chock wheels. Turn engine off.
- Clean the brake fluid reservoir cap area; remove cap and diaphragm carefully to avoid contamination.
- Place rags under calipers and bleed nipples to protect finish and catch drips.
- If using a vacuum bleeder, attach clear tubing from the bleed nipple to the catch bottle and fit the vacuum gun to the other end.
Bleeding order
Bleed from the caliper furthest from the master cylinder first, then work toward the closest. For the Kodiak 700 4X4 IRS the recommended sequence is:
- Right rear (furthest)
- Left rear
- Right front
- Left front (closest)
Step-by-step flush & bleed (vacuum bleeder method)
- Top off the master cylinder reservoir with fresh DOT 4 brake fluid so the level is at the "max" mark. Keep the cap loose but reinstalled so dust cannot enter.
- Start with the right rear caliper. Place clear tubing over the bleed nipple and route into a catch bottle partially filled with a little fresh fluid to prevent air reingress.
- Open the bleed nipple about a quarter turn with the correct wrench.
- Apply vacuum to the tubing. Draw fluid until the expelled fluid runs clear and bubblefree, and you see fresh fluid rather than old dark fluid. Keep the master cylinder topped up during the entire process so air does not enter the system.
- Close the bleed nipple while maintaining vacuum, then remove tubing. Wipe the nipple and torque to snug (do not overtorque). Repeat this process for each wheel following the bleed order above.
Step-by-step pump & hold (two-person) method
- Partner pumps the brake pedal several times and holds steady pressure at mid travel.
- You open the bleed nipple to let fluid/air escape until flow subsides, then close it while pedal is still held down. Partner slowly releases pedal once nipple is closed.
- Repeat pump, hold, crack, close until clear, bubblefree fluid appears and pedal feel is firm. Keep reservoir topped off throughout.
Final steps
- When the last caliper is clear, ensure the reservoir is filled to the recommended level and reinstall diaphragm and cap securely.
- Operate the brake pedal/lever several times to confirm firm, consistent feel. If soft or spongy, repeat bleeding until solid.
- Inspect all bleed nipples, hoses, banjo bolts and master cylinder area for leaks. Torque any caliper or reservoir bolts to spec.
- Clean any spilled fluid with water immediately and treat painted surfaces per Yamaha guidance.
- Dispose of old brake fluid responsibly; it is hazardous waste.
Troubleshooting & tips
- If persistent sponginess remains, check for soft or damaged hoses, internal master cylinder issues, or hidden air pockets. Hoses older than 5-7 years should be replaced.
- For stubborn air, use the pedalhigh method: fully depress pedal and hold, open bleed nipple very briefly, then close and release pedal. Repeat few cycles while keeping reservoir full.
- Keep work area clean & use glovesthe system cannot tolerate contamination. Never mix DOT 3/4 with silicone fluids.
- After service, perform a lowspeed brake check in a safe area before riding at speed or on difficult terrain.
Maintenance schedule recommendation
Flush and replace brake fluid every 2 years or sooner if the fluid appears dark, contaminated, or if you use the Kodiak in heavy, wet, or hightemperature conditions often. Regular checks of brake lines, fittings and pads should be part of your seasonal inspection.
