This MotoSport guide covers a complete, model-aware procedure to safely drain, flush, and bleed the brake system on a 2011 Suzuki King Quad 500AXi 4X4 Power Steering. Follow these steps exactly, use proper PPE, and consult your service manual for torque values and any model-specific callouts.

Safety & prep

  • Work on a level surface with the engine off, key removed, and parking brake engaged.
  • Wear safety glasses and gloves. Brake fluid is corrosive to paint & plastics; protect bodywork and clean spills immediately.
  • Use only the brake fluid specified on the master cylinder reservoir cap — usually DOT 3 or DOT 4. If in doubt, follow the reservoir cap or Suzuki OEM recommendation.
  • Have a clean catch container, clear vinyl tubing, rags, a turkey-baster or fluid-syringe, a wrench sized for the bleed nipples (usually 8-10 mm), and a spare bottle of fresh brake fluid.
  • If you lack an assistant, use a hand/vacuum brake bleeder or pressure bleeder for a one-person job.

Model-specific notes for the 2011 King Quad 500AXi

  • The 500AXi uses hydraulic brakes with accessible bleed nipples on the front calipers and the rear brake assembly. Verify whether your rear is a disc or drum style — many King Quad configurations have front dual discs and a rear disc or drum depending on trim; locate the bleed nipple(s) before beginning.
  • This model has power steering with a separate hydraulic system — do NOT open or mix power steering fluid with brake fluid. Brake reservoir is separate and typically located near the handlebars or front frame; label and avoid confusing caps.
  • Corroded or rounded bleed nipples are common on older units; inspect and replace nipples or use penetrating oil if stuck. Replace rubber caps after bleeding to keep moisture out.
  • If plastic reservoir is cloudy or contaminated, replace it; contamination shortens brake component life on this model.

Step-by-step: Full fluid replacement (recommended)

  1. Open the master cylinder reservoir. Siphon out old fluid with a turkey-baster or syringe until level is low but some fluid remains to prevent air ingestion. Wipe the cap and reservoir mouth clean before resealing between steps.
  2. Top reservoir with fresh brake fluid to the proper level; keep the cap loosely in place to reduce contamination while still allowing overflow.
  3. Identify bleeding order: generally start with the furthest wheel from the master cylinder and work toward the closest. On many King Quad layouts this means: right front, left front, then rear. Confirm on your machine by visual inspection of hose routing.
  4. Fit a clear vinyl hose over the bleed nipple and place the other end into a catch bottle partly filled with fresh fluid to prevent air being drawn back in. If using a vacuum bleeder, attach per tool instructions.
  5. Have an assistant pump the brake lever or pedal slowly 3-5 times and hold pressure. Open the bleed nipple about 1/4 turn to let fluid & air exit; close the nipple before your assistant releases pressure. Repeat until clear fluid with no bubbles appears, then move to next wheel. If using vacuum bleeder, run until only clean fluid flows and no bubbles remain.
  6. Keep the master cylinder reservoir topped during the entire procedure. Never allow it to run dry or you will reintroduce air into the system and must start over.
  7. After all wheels are bled, perform a final bleed pass from nearest to furthest to ensure no trapped air remains. Check lever/pedal for firm feel.
  8. Clean all fittings, torque bleed nipples to spec if available, reinstall rubber caps, and clean up any spilled fluid from painted surfaces. Refill the reservoir to the specified level and secure the cap.
  9. Road test cautiously at low speed in a safe area to confirm firm braking. Recheck reservoir level and inspect for leaks after the test.

Alternative single-person methods

  • Vacuum bleeder: attach to bleed nipple, pump until clear fluid shows. Keep reservoir topped.
  • Pressure bleeder: screws to the master cylinder cap — pressurizes reservoir and forces fluid through; follow tool directions and keep pressure steady.
  • Gravity bleed: open bleed nipples and let fluid drip slowly; this is slow and less reliable for removing all air but can work for minor top-ups.

Inspection & replacement checklist (MotoSport recommended)

  • Brake lines: check for cracks, swelling, soft spots, or brittle rubber. Replace if age or damage is evident.
  • Bleed nipples: replace if rounded, corroded, or leaking.
  • Calipers & pistons: ensure pistons move smoothly and seals are intact; rebuild kits are inexpensive and recommended for units with sticking pistons.
  • Brake pads & shoes: check thickness & wear patterns; replace if uneven or below spec.
  • Reservoir cap diaphragm: replace if hardened or damaged to maintain a moisture barrier.
  • Brake hoses: consider braided stainless replacement for improved feel and longevity if you ride aggressively or in wet conditions.

Troubleshooting common issues

  • Spongy lever/pedal after bleeding: likely air left in system or master cylinder internal leak. Repeat bleeding sequence; inspect master cylinder for internal leaks.
  • Brake drag after bleeding: caliper pistons may be sticking or parking brake adjustment binding. Inspect and free pins/pistons as needed.
  • Persistent leaks: tighten or replace leaking line fittings, nipples, or replace caliper seals.

Maintenance intervals & final tips

  • Brake fluid absorbs moisture; MotoSport recommends full fluid replacement every 1-2 years depending on use and environment (more often if you ride in wet/marine conditions).
  • Always use fresh, unopened brake fluid and discard any fluid left in partially used bottles after long storage.
  • Log service dates and parts replaced. On the 2011 King Quad 500AXi, proactive brake hose and caliper maintenance preserves stopping performance and prevents costly failures on trail.
