This MotoSport guide walks you through safely flushing and replacing the brake hydraulic fluid on a 2014 Suzuki King Quad 750AXi 4X4 POWER STEERING. The procedure below is written for the King Quad platform and highlights model-specific notes so you maintain pedal feel and brake component longevity.
Safety & preparation
- Work on a flat, stable surface. Chock wheels and block the machine so it cannot roll.
- Wear safety glasses and nitrile gloves. Brake fluid damages paint & plastics; protect surrounding surfaces.
- Use correct brake fluid type per Suzuki specification for your MMY ATV. If you don't have the manual, use a high-quality DOT 3 or DOT 4 brake fluid that meets JIS/DOT specs and replace seals if they are old or soft.
- Do not mix brake fluid with power steering fluid. The King Quad 750AXi has a hydraulic power steering systemkeep reservoirs and caps clearly separated.
- Have a helper for manual bleeding or a pressure/vacuum bleeder for single-person operation.
Tools & supplies
- Correct brake fluid (fresh sealed container)
- Clear vinyl tubing (fits bleeder nipples)
- Catch bottle partially filled with old fluid to prevent air intake
- Combination wrenches for bleeder nipples (typically 8mm or 10mm)
- Syringe or turkey baster to remove reservoir fluid
- Rags, cleaning solvent, gloves, and drip tray
- Floor jack and stands if lifting is needed
- Vacuum or pressure brake bleeder (optional but speeds job and reduces air ingress)
Model notes for the 2014 King Quad 750AXi
- This model typically uses dual front disc brakes and a single rear disc. Bleeding order follows distance from the master cylinder: farthest caliper first then closest.
- Power steering uses a separate hydraulic circuit; never open power steering components when changing brake fluid.
- ABS is not standard on many King Quad 2014 models. If your unit has an ABS module or factory anti-lock option, consult factory service info before disconnecting lines or actuators.
- Banjo bolts on calipers use crush washers. Replace crush washers whenever you remove a banjo bolt to prevent leaks.
Bleeding & fluid replacement procedure
- Park ATV, chock wheels, and remove seat/access panels needed to reach the brake master cylinder reservoir. Clean around the reservoir cap before opening to prevent contamination.
- Remove reservoir cap and diaphragm carefully. Use a turkey baster or syringe to remove most old fluid from the reservoir; dispose of it properly.
- Top the reservoir with fresh fluid to the specified level. Keep the reservoir cap off but protected to prevent debris from entering during the bleed.
- If using a gravity or pressure bleeder, connect it to the reservoir per tool instructions; if manual, have your helper ready in the cab to operate the brake lever/pedal.
- Locate bleeder nipples on calipers. The bleeding order should be: far-right front caliper (if mounted remotely), far-left front caliper, then rear caliper — ultimately bleed the caliper farthest from the master cylinder first and finish with the nearest. On King Quad layouts that place the master cylinder near the right side, verify distances visually; priority is farthest to nearest.
- Attach clear tubing to the first bleeder nipple and submerge the other end in the catch bottle partially filled with old fluid to prevent air return.
- Open bleeder nipple ~1/4 to 1/2 turn. Have your helper slowly depress and hold the brake lever/pedal, then open the bleeder to allow fluid and bubbles to exit until flow is steady and bubble-free, then close the bleeder before the helper releases the pedal. Repeat until clean fluid appears. Monitor reservoir level and top as needed to avoid running dry.
- Move to the next caliper in the order and repeat the same open-pump-close sequence until all calipers are clear of air and fluid runs clean and clear.
- When finished, tighten all bleeder nipples to factory snugness. Wipe all connections clean and ensure no leaks. Replace reservoir diaphragm and cap.
- Test brake lever/pedal firmness with the ATV still on stands. If the lever feels spongy, repeat bleeding focusing on problem branch or use a vacuum bleeder on the individual caliper.
- Lower ATV, perform a low-speed brake test in a safe area to verify consistent pedal feel and stopping performance. Check for leaks after test ride and re-torque banjo bolts if necessary with new crush washers.
Tips & troubleshooting
- If you keep getting air in one caliper, inspect hoses and banjo connections for leaks or collapsed hose sections; replace soft or cracked hoses.
- Stubborn air pockets may accumulate at higher points in lines; slightly changing wheel position or raising the wheel while bleeding can help dislodge trapped air.
- Always discard used brake fluid and contaminated tools; do not reuse fluid from the catch bottle.
- If brake lever/pedal travel is still excessive after thorough bleeding, inspect the master cylinder for internal seal wear and consider rebuild or replacement.
Post-service checks
- Verify reservoir level after several rides and recheck for leaks.
- Inspect brake pad thickness and rotor condition when you have the wheels off — replace worn pads or scored rotors which can affect braking performance.
- Note next fluid change interval: brake fluid is hygroscopic and should be replaced every 1-2 years depending on use and climate.
Follow these steps to restore proper braking performance on your 2014 Suzuki King Quad 750AXi 4X4 POWER STEERING. For OEM replacement parts, calipers, hoses, and fresh fluid compatible with your MMY ATV, visit MotoSport for fitment-verified components.
