This MotoSport-exclusive procedure walks you safely through bleeding and replacing the brake fluid on a 2013 Suzuki King Quad 750AXi 4X4 Power Steering (MMY KingQD750P). Follow every step carefully. If you are not confident working on hydraulic brakes, have a trained technician perform the job.

What you need

  • Manufacturer-specified brake fluid (use DOT-rated fluid per your owner's manual; DOT 3 or DOT 4 compatibility is common — verify the cap or manual)
  • Brake bleeder kit or clear tubing and a catch bottle
  • Turkey baster or fluid syringe to remove old fluid from reservoir
  • Clean rags, rubber gloves, eye protection
  • Floor jack or ramps and stands (securely support ATV)
  • Wrenches to fit bleed nipples (usually 8 mm or 10 mm) and basic hand tools
  • Brake cleaner and a small funnel
  • Torque wrench (for caliper fasteners if you remove them)

Safety & prep

  • Work on a level surface with the engine off and key removed.
  • Protect painted surfaces from brake fluid; it will damage paint. Keep rags handy.
  • Wear eye protection and gloves; brake fluid is corrosive to skin and eyes.
  • Park brake should be applied if present; block wheels if needed.
  • Check for ABS or additional hydraulic components on your unit; this model is typically non-ABS but confirm before proceeding.

Step 1 Inspect the system

  • Open the brake master cylinder reservoir cap. Clean area before opening to prevent contamination.
  • Check fluid color and level. Dark, dirty fluid or moisture indicates replacement is needed.
  • Inspect brake lines, hoses, calipers, pads, and connections for leaks or damage. Repair any leaks before bleeding.

Step 2 Remove old fluid from reservoir

  • Use a turkey baster or syringe to remove as much old fluid from the reservoir as possible without letting air into the master cylinder.
  • Wipe the reservoir clean with a lint-free rag and add fresh fluid to the "MAX" level. Do not overfill.

Step 3 Bleeding order and principles

  • Always bleed from the wheel farthest from the master cylinder toward the nearest. For most King Quad layouts that means: rear far side, rear near side, front far side, front near side. If routing or master location differs, use farthest-to-nearest logic.
  • Keep the reservoir topped with fresh fluid during the entire process to avoid drawing air into the master cylinder.
  • Use clean, DOT-specified fluid only. Never mix DOT 3 with DOT 5 (silicone).

Step 4 Manual bleed method (single person)

  • Attach clear tubing to the bleed nipple and place the other end in a catch bottle partially filled with fresh fluid to avoid air ingress.
  • Have an assistant slowly depress the brake lever/pedal several times and hold pressure. While held, open the bleed nipple briefly to let fluid and air escape, then close the nipple before the assistant releases pressure. Repeat until clear fluid without air bubbles appears.
  • Top up the reservoir between cycles to keep it above the minimum mark.
  • Repeat the process for each wheel in the correct order.

Step 5 Vacuum or pressure bleeding (recommended for one-person operation)

  • If using a vacuum bleeder, attach vacuum hose to the bleed nipple and apply vacuum while pumping the brake lever/pedal slowly until clean fluid flows and no air bubbles appear. Keep reservoir topped.
  • If using a pressure bleeder, follow the tool manufacturer's instructions and monitor reservoir level closely.

Step 6 Final steps and checks

  • After bleeding all lines, ensure bleed nipples are tightened to spec (snug; avoid rounding). If you removed calipers or fasteners, torque to values in your service manual.
  • Refill the reservoir to the correct level and replace the cap securely.
  • Pump the brake lever/pedal to build firm pressure. A spongy lever indicates remaining air repeat bleeding until firm.
  • Check for leaks at every bleed nipple and along lines with pressure applied.
  • Dispose of used brake fluid properly at a recycling center.

Break-in and road test

  • Test brakes at low speed in a safe area to confirm consistent, firm braking.
  • Bed-in new pads if installed: perform several moderate stops from low speed to seat pads and check again for proper feel.

Model-specific notes for the 2013 King Quad 750AXi 4X4 Power Steering

  • The King Quad 750AXi power steering system does not share brake fluid with the power steering fluid; avoid cross-contamination. Keep fluids separate and identify caps clearly.
  • This model's master cylinder reservoir is exposed; keep a tight seal on the cap when finished to prevent moisture absorption into DOT fluid, which degrades braking performance.
  • If your unit has aftermarket lift kits, oversized tires, or modified brake lines, bleeding may take longer and lines should be inspected for routing or strain. Aftermarket components can change bleed order or add additional bleed points.
  • Regular brake fluid replacement interval: every 2 years is a common preventive schedule to avoid moisture buildup and corrosion. If you ride in wet or muddy conditions frequently, check fluid more often.
  • If you hear unusual noises from the power steering during or after brake work, confirm you did not disturb steering hoses or electrical connectors; recheck mounting hardware.

Troubleshooting

  • Persistent soft lever after thorough bleeding: inspect master cylinder seals and caliper pistons for leaks or corrosion; replace components as needed.
  • Brake drag after bleeding: check caliper pistons for sticking, verify caliper slide pins are free and lubricated, and ensure hose routing is free of kinks.
  • Air reenters system after bleeding: check reservoir cap gasket and master cylinder for correct sealing, and ensure reservoir never fell below minimum during bleeding.
