This MotoSport-exclusive guide walks through a complete brake fluid replacement & bleed for the 2014 Suzuki King Quad 500AXi 4x4. Follow these steps carefully to restore firm lever/pedal feel and prevent contamination. If you’re not comfortable with brake systems, have a certified tech perform the work.

What you’ll need

  • DOT 4 brake fluid (use only the type specified in your owner’s manual; most 500AXi models use DOT 4)
  • Clear plastic hose that fits bleed nipples
  • Catch bottle or jar
  • Wrench set (open/box wrenches for bleed nipples)
  • Brake bleeder pump or vacuum pump (optional) or a helper for two-person method
  • Turkey baster or syringe (for removing old fluid from reservoir)
  • Clean rags, gloves, safety glasses
  • Torque wrench (for caliper mounting hardware if removed)

Safety & prep

  • Work on a level surface with the engine off and key removed.
  • Protect paint and plastics — brake fluid damages finishes. Cover tanks and body panels with rags.
  • Keep all brake fluid containers sealed & clean. Never reuse old fluid.
  • If your bike has ABS or an electronic system, consult the service manual for an ABS-specific bleed procedure before proceeding.

Model notes for the 2014 King Quad 500AXi 4x4

  • The 500AXi uses hydraulic front & rear disc brakes with a single master cylinder. There’s no factory vacuum-assist system; manual pressure is used at lever/pedal.
  • Typical bleed order is farthest caliper from the master cylinder first — this may be rear-right, then rear-left, then front-left, then front-right. Confirm location of the master cylinder on your machine and follow farthest-to-closest rule.
  • Check for worn hoses, leaking calipers, or a soft master cylinder; if the pedal/lever still feels spongy after bleeding, inspect hardware for air ingress or component wear.

Step 1 – Access & inspect

  • Remove any panels needed to access the brake fluid reservoir and bleeder nipples. Clean the reservoir cap area to prevent contamination.
  • Inspect lines, fittings, calipers, and the reservoir for cracks, leaks, or damage. Replace worn hoses or leaking parts before bleeding.

Step 2 – Drain the reservoir

  • Use a turkey baster or syringe to remove as much old fluid from the reservoir as possible. Dispose of old fluid properly.
  • Refill the reservoir with fresh DOT 4 fluid to the MAX line, keeping the cap loosely on to limit contamination while preventing overflow during movement.

Step 3 – Bleed sequence — general rule

Always bleed from the caliper farthest from the master cylinder first, then proceed to the next farthest, finishing at the caliper closest to the master cylinder. This purges air from the longest lines first.

Step 4 – Two-person bleed method

  1. Person A pumps the lever/pedal several times and holds steady pressure (or holds it down if using the pedal).
  2. Person B opens the bleed nipple about 1/4 turn until fluid flows into the clear hose and the lever/pedal drops slightly, then closes the nipple. Repeat until only clean fluid (no bubbles) appears, topping the reservoir frequently.
  3. Work quickly to keep the reservoir from running dry. Repeat at each caliper following the farthest-to-closest order.

Step 5 – One-person vacuum or pressure bleed method

  • Attach the clear hose to the bleed nipple and the other end to the vacuum pump or a catch bottle.
  • Open the bleed nipple and apply vacuum while someone gently actuates the lever/pedal (if using a one-person tool, pump according to tool instructions). Continue until fluid runs clear and bubbles stop.
  • Close the nipple before releasing vacuum to prevent drawing air back into the system.

Step 6 – Final checks

  • Top reservoir to proper level and secure the cap. Wipe any spilled fluid immediately.
  • With the vehicle on a stable stand and wheels off the ground, confirm firm pedal/lever feel. If spongy, repeat bleeding.
  • Torque any removed caliper or line fittings to factory specs if you removed hardware. Check the service manual for exact torque values.
  • Test ride slowly in a safe area and recheck for leaks and brake function after a short ride.

Maintenance tips & troubleshooting

  • Replace brake fluid every 1-2 years or sooner if it becomes dark or contaminated. Brake fluid absorbs moisture which reduces boiling point and can cause corrosion.
  • If you see persistent air or a soft pedal, inspect the master cylinder for internal leaks or contamination and inspect caliper pistons and seals.
  • Always use a clean funnel and never top off with a different fluid type — mix only identical DOT-rated fluid.
