This MotoSport guide walks you through safe, correct brake-fluid replacement and bleeding on the 2017 Suzuki King Quad 500AXi 4X4 POWER STEERING (MMY KINGQD500P). Follow all safety steps, use the correct fluid, and inspect brake components while you work.

What you need

  • Brake fluid: DOT 3 (compatible with DOT 4) — use fresh, unopened fluid and never mix with unknown fluids
  • Wrench set (open-end or box for bleeder nipples)
  • Clear tubing that fits snugly on bleeder nipples
  • Catch container for old fluid
  • Clean rags, gloves, eye protection
  • Screwdriver or strap wrench for reservoir cap, funnel (optional)
  • Assistant (recommended) or a one-man vacuum/pressure bleeder
  • Brake-clean spray and a small brush for caliper cleaning

Model notes & precautions specific to the 2017 King Quad 500AXi

  • The King Quad 500AXi uses a hydraulic front and rear disc brake system with a single master cylinder reservoir. Reservoir is located ahead of the handlebars under the front plastic cover; remove covers to access.
  • This model has power steering — take care not to let brake fluid contact painted or plastic surfaces, or steering seals. Brake fluid is hygroscopic and will degrade rubber over time.
  • ABS is not present on this MMY; bleeding is conventional. If you have aftermarket modifications to brake lines, follow their instructions.
  • Inspect calipers, pads, rotors, hoses, and banjo fittings while bleeding. Replace any cracked hoses or perished seals before completing the job.
  • Brake fluid is corrosive and flammable; handle & dispose of used fluid per local regulations.

Preparation

  1. Park the ATV on level ground, engage parking brake, put transmission in park/neutral, and disconnect the negative battery terminal for safety if you plan to move controls or remove electrical components.
  2. Remove the front plastic cover to access the brake-fluid reservoir. Clean the area around the cap to avoid contamination.
  3. Top up the reservoir with new DOT 3 fluid to the MAX mark. Keep the bottle sealed when not in use to avoid moisture uptake.
  4. Lift the ATV safely if you plan to remove wheels for better access to bleeder nipples on calipers. Use jack stands rated for ATVs.

Bleeding order

Bleed the farthest caliper from the master cylinder first, then move closer. Typical sequence on King Quad 500AXi:

  1. Right rear (farthest)
  2. Left rear
  3. Right front
  4. Left front (closest)

Traditional two-person bleed method

  1. Attach clear tubing to the bleeder nipple; place the other end into a catch container partially filled with clean fluid to prevent air from re-entering.
  2. Have your assistant slowly pump the brake pedal 5 to 10 times, then hold firm pressure on the pedal.
  3. Open the bleeder nipple about 1/4 turn and allow fluid and air to exit until flow is steady and clear. Close the nipple before your assistant releases the pedal.
  4. Repeat pumping and opening until no air bubbles appear and pedal feel is firm. Keep an eye on the reservoir fluid level and top up frequently to prevent introducing air.
  5. Work through the bleed order: right rear, left rear, right front, left front.
  6. After all calipers are bled, ensure the reservoir is filled to the proper mark, tighten the cap, clean any spills, and test pedal firmness with ignition on (to restore power steering if disconnected) and engine off.

One-person vacuum or pressure bleed method

  1. Connect a vacuum pump to each bleeder nipple in turn, or use a pressure bleeder on the master-cylinder reservoir per the tool instructions.
  2. Open the bleeder and draw fluid until steady and bubble-free. Keep reservoir topped up.
  3. Follow the same bleed order. Close bleeders and torque to spec when finished.

Finishing steps & checks

  • Torque bleeder nipples and banjo bolt fittings to factory specs (if unknown, snug and then an additional 1/8 to 1/4 turn; avoid over-tightening).
  • Wipe all components dry, remove any spilled fluid immediately, and inspect pad wear and rotor condition. Replace pads if thinning or glazing is present.
  • Reinstall any removed plastic covers/wheels and lower the ATV. Reconnect battery if disconnected.
  • Start the ATV, operate the brake lever/pedal several times, and verify firm pedal feel at normal operating temperature. Perform a low-speed brake test in a safe area before heavy use.

Troubleshooting

  • Soft or sinking pedal after bleeding: check for leaks, air trapped in system, or internal master-cylinder seal failure. Repeat bleeding; if problem persists, inspect/replace master cylinder.
  • Persistent air: use the one-way bleed or reverse-bleed technique at caliper pistons (careful not to push fluid back into the master cylinder). A pressure bleeder often resolves stubborn air pockets.
  • Contaminated fluid (dark, filthy): flush entire system until new fluid runs clear.

Maintenance tips

  • Replace brake fluid every 24 months or sooner if exposed to moisture or heavy use.
  • Always use fresh DOT 3 (or DOT 4-compatible) fluid from a sealed container.
  • Store extra fluid in a cool, dry place and reseal the bottle immediately after use.
  • Regularly inspect brake hoses for swelling or cracking — replace if any damage or softening is found.

Following this MotoSport procedure will keep your 2017 Suzuki King Quad 500AXi 4X4 POWER STEERING braking system reliable and safe. If you encounter mechanical issues beyond routine bleeding & fluid replacement, consult a certified technician.
