How to Bleed & Replace Brake Fluid on a 2011 Honda TRX500 Foreman 4X4 ES POWER STEERING (FE2)

This MotoSport-exclusive guide walks through a safe, thorough brake fluid replacement and bleed procedure tailored for the 2011 Honda TRX500 Foreman 4X4 ES POWER STEERING (FE2). Follow every step carefully, work cleanly, and wear eye protection and gloves. Use DOT 4 brake fluid unless your owner’s manual specifies otherwise; do not mix mineral-based fluids. Proper disposal of used fluid is required by local regulations.

What you’ll need

  • DOT 4 brake fluid (new, unopened)
  • Clear tubing to fit bleed nipples
  • Catch bottle partially filled with fresh fluid (to seal tube end)
  • Wrenches sized to bleed nipples (usually 8mm or 10mm)
  • Rubber gloves, shop rags, safety glasses
  • Brake cleaner, new crush washers for banjo bolts if removing lines
  • Jack or ramps and stands to raise wheels if needed
  • Assistant (recommended) or a vacuum/pressure bleeder
  • Torque wrench (for any removed caliper or banjo hardware)

Model notes — things 2011 TRX500FE owners should know

  • The TRX500FE has power steering; avoid contact between brake fluid and power steering components or seals. Wipe any spills immediately & rinse with water if necessary then dry.
  • This model can develop hardened or cracked rubber hoses and deteriorating caliper seals with age – inspect hoses, banjo bolts and caliper boots while you’re servicing the brakes.
  • Brake master cylinder reservoirs are small & can run low quickly when flushing; do not let the master run dry during the procedure or you will introduce air and require extra bleeding.
  • Old fluid may be dark and contaminated; a full flush is recommended rather than topping off to restore braking performance and protect internal components.
  • If a spongy pedal or continued softness persists after bleeding, check caliper pistons, ABS components (if fitted), and master cylinder condition — components on a 2011 model may need rebuilding or replacement.

Preparation

  • Park on level ground, engage parking brake, switch OFF ignition, remove key.
  • Clean the master cylinder reservoir cap area to avoid contamination. Remove the cap and diaphragm and cover the reservoir mouth with a clean cloth to keep dirt out.
  • Raise the wheels as required so you can access bleed nipples on each caliper comfortably. Secure the machine on stands.
  • Confirm the correct brake fluid type and have fresh fluid ready. Keep the reservoir cap loosely on but not sealed until you're actively flushing to avoid pressure build-up.

Bleeding order principle

Always bleed starting at the caliper farthest from the master cylinder and finish with the closest. On many ATVs the typical sequence is: rear far side, rear near side, front far side, front near side. Confirm which caliper is farthest from the master cylinder on your machine and follow that sequence.

Two-person pump-and-hold method (recommended)

  1. Top off the master cylinder with fresh DOT 4 fluid. Keep the cap loosely set aside; do not let fluid run low.
  2. Have your assistant sit on the ATV and gently pump the brake pedal 3–6 times then hold firm pressure on the pedal.
  3. Open the bleed nipple at the targeted caliper about a 1/4 turn, allowing fluid and air to flow into the tubing and into your catch bottle. Close the nipple BEFORE your assistant releases the pedal. Watch the master reservoir and top up as needed to prevent it from running dry.
  4. Repeat the pump-hold-open-close cycle until the fluid runs clear and no air bubbles appear in the tubing for that caliper.
  5. Move to the next caliper in the bleeding order and repeat. Always watch and maintain fluid level in the master reservoir.
  6. When finished with the closest caliper, verify the pedal is firm with steady pressure. Tighten bleed nipples to specified snugness (do not over-torque) and clean any spilled fluid.

Single-person vacuum or pressure bleeder method

  • Attach the vacuum pump hose to the caliper bleed nipple. Keep the reservoir topped off while you draw fluid through each caliper in order from farthest to nearest. Follow vacuum pump manufacturer's instructions.
  • For pressure bleeders, pressurize the master reservoir per tool instructions and open bleeders one at a time in the correct sequence until clear fluid appears.

If you remove brake lines or banjo bolts

  • Replace crush washers on banjo bolts with new ones to ensure a leak-free seal.
  • Use new copper washers or OEM spec parts. Torque banjo bolts to manufacturer spec if available, or snug to a firm seal and verify no leaks under pressure.

Final checks & cleanup

  • Top the master reservoir to the full mark, install the diaphragm and cap securely.
  • Operate the brake lever/pedal several times to confirm a firm, non-spongy feel. Re-check all bleed nipples and line connections for leaks while pressure is applied.
  • Lower the ATV, test brakes at low speed in a safe area until you confirm normal braking behavior.
  • Dispose of used fluid responsibly. Clean any painted surfaces quickly — brake fluid will damage paint.

Troubleshooting

  • Persistent soft pedal after proper bleeding: suspect master cylinder internal seal failure, clogged line, or collapsed hose. Inspect and replace components as necessary.
  • Air keeps returning: ensure the master reservoir didn't run dry at any point, check for leaks or cracked hoses and confirm all bleeder valves seat properly.
  • Leaking caliper seals: if fluid seeps past piston seals, caliper rebuild or replacement is required.

Maintenance tips

  • Replace brake fluid every 1–2 years depending on use and exposure to moisture.
  • Inspect hoses, fittings and caliper dust boots each service; replace any aged or cracked parts promptly.
  • Keep a small supply of DOT 4 fluid on hand for topping between full flushes and during trail-side emergencies.

Follow this MotoSport-specific procedure to restore proper braking performance on your 2011 TRX500FE. If you’re uncomfortable with any step, contact a qualified technician to perform the service.
