How to Bleed and Replace Brake Fluid on a 2014 Suzuki King Quad 500AXi 4X4 POWER STEERING

Shop parts for a 2014 Suzuki King Quad 500AXi 4X4 POWER STEERING ATV.

This MotoSport-exclusive procedure covers draining, flushing, and bleeding the hydraulic brake system on the 2014 Suzuki King Quad 500AXi 4X4 POWER STEERING (MMY code KINGQD500P). Follow these steps to restore brake performance and fluid condition using DOT 3/4 compatible fluid as specified by Suzuki. Work in a clean, well-lit area and take safety precautions for brake fluid handling.

Tools & supplies

  • DOT 3 or DOT 4 brake fluid (check reservoir cap marking on your ATV)
  • Brake bleeder wrench or small open-end wrench (8 mm or 10 mmverify caliper bleeder size)
  • Clear plastic tubing to fit over bleeder nipple
  • Catch bottle for old fluid
  • Syringe or turkey-baster for reservoir fluid removal
  • Brake cleaner and shop rags
  • Torque wrench for caliper/reassembly needs
  • Jack or ramps and stands to safely support the ATV if wheels are removed
  • Gloves and eye protection; plastic bag & tape to cover reservoir cap during pumping

Model-specific notes for the 2014 King Quad 500AXi POWER STEERING

  • The King Quad 500AXi uses a combined front/rear hydraulic system with a single reservoir (located under the seat or handlebar shroud depending on configuration). Confirm reservoir location on your unit before starting.
  • Power steering models route hydraulic lines near the steering gear; avoid kinking lines when raising the front end or turning the handlebars fully.
  • 2009-2014 King Quad models sometimes have mixed fittings; verify bleeder nipple size and thread direction before forcing tools. Left/right caliper bleeder orientation may differ.
  • ABS is not fitted on this model, so bleeding is straightforwardno ABS pump cycle required.
  • Recommended replacement parts: new bleed nipple washers and, if hoses are older/cracked, replace flexible brake hoses. Use OEM-style components available through MotoSport.

Preparation

  • Park the ATV on level ground, engage park/neutral and remove the key. Chock wheels.
  • If you'll remove wheels to access calipers, support ATV securely on standsnever rely on the suspension jacks alone.
  • Clean the reservoir cap area with brake cleaner to avoid contamination when opened.
  • Inspect brake lines, fittings, and calipers for leaks, corrosion, or damage. Replace suspect hoses before bleeding.

Step 1 Determine correct brake fluid

Check the reservoir cap or owner's manual for DOT rating. Use fresh, unopened DOT 3 or DOT 4 brake fluid as specified. Do not mix mineral oil or other hydraulic fluids. Brake fluid absorbs moisture quickly; keep the bottle closed until use.

Step 2 Remove old fluid from reservoir

  • Open the reservoir and use a syringe or turkey-baster to remove as much old fluid as possible.
  • Wipe the inside of the cap and the reservoir lip with a clean rag. Do not allow dirt to fall into the reservoir.

Step 3 Fill with fresh fluid and prepare bleed fittings

  • Fill the reservoir to the full mark with fresh fluid. Keep the cap loosely fitted to reduce contamination while you work.
  • Identify bleed sequence: on most King Quad setups bleed from the caliper furthest from the master cylinder first. For this model: typically rear left – rear right – front left – front right. Confirm layout visually by tracing lines back to the reservoir.
  • Place clear tubing on the bleeder nipple and route it into a catch bottle partially filled with fresh fluid to prevent air re-entry.

Step 4 Manual two-person bleed (preferred)

  • Person A sits on the vehicle and slowly pumps the brake lever/pedal several times, then holds steady pressure.
  • Person B opens the bleeder nipple about 1/4 turn with the correct wrench until fluid and air bubbles flow into the tubing, then closes the nipple before Person A releases pressure. Repeat until no air bubbles appear and clear fluid runs.
  • Watch the reservoir level closely; top up with fresh fluid between cycles to prevent the master cylinder from drawing air.
  • Repeat the sequence for each caliper in the correct order.

Step 5 One-person vacuum or pressure bleeding (alternative)

  • Use a hand vacuum pump on the bleeder nipple or a pressure bleeder on the reservoir. Follow tool instructions. Keep reservoir topped with fluid during the process.
  • Vacuum bleeding is efficient for a single operator and reduces the chance of sucking air back through the caliper when closing the nipple.

Step 6 Final checks & torque

  • After all calipers are bled and the fluid shows no bubbles, tighten bleeder nipples to specified snugness (do not over-torque). If you removed wheels or calipers, torque wheel nuts and caliper bolts to factory specconsult service manual for exact values for KINGQD500P.
  • Top the reservoir to the full mark, install the cap, and clean any spilled fluid immediately. Brake fluid damages paint and plastic.
  • Sit on the machine and apply firm brake pressure several times to confirm firm pedal/lever feel. If it feels spongy, repeat bleeding until firm.
  • Test brakes at low speed in a safe area before normal riding to verify proper operation.

Disposal

Collect used brake fluid and dispose of it at an appropriate hazardous-waste facility. Do not pour down drains or onto the ground.

Troubleshooting

  • Persistent spongy lever after thorough bleeding: inspect master cylinder seals, caliper pistons, or internal air leaks. Replace faulty components.
  • Visible contamination or dark fluid that returns quickly to dark after repeated bleeding: consider a full system flush and replace soft lines and reservoir components as needed.
  • If a bleeder nipple is rounded or stuck, apply penetrating fluid carefully and use the correct wrench; replace nipple if damaged.

Recommended MotoSport parts & spares for this job

  • Fresh DOT 3/4 brake fluid
  • Replacement bleeder nipples and copper crush washers
  • OEM or OEM-style brake hoses for KINGQD500P if lines are aged
  • Caliper rebuild kits if pistons or seals leak

Perform regular inspections of brake hoses for cracking or swelling and change fluid every 1-2 years depending on use and storage. Keeping clean, dry fluid in the King Quad 500AXi POWER STEERING keeps stopping power reliable and minimizes costly caliper or master cylinder repairs.
