This MotoSport proprietary guide walks you through safely flushing and bleeding the entire brake system on a 2014 Honda TRX500 Foreman 4X4 POWER STEERING (FM2). Follow these steps to restore firm lever/pedal feel, remove moisture-contaminated fluid, and keep braking performance reliable.
What you need
- DOT 3 brake fluid (Honda recommends DOT 3; DOT 4 is compatible if specified by replacement parts)
- Clear tubing that fits bleeder nipples
- Catch bottle for old fluid
- Brake bleeder kit (vacuum pump or pressure bleeder) or a helper
- Wrenches for bleeder screws (usually 8 mm) and reservoir cap tool
- Clean rags, gloves, safety glasses
- Jack, stands or ramps if wheel removal is needed
- Brake parts cleaner for cleanup
Safety & model notes
- Brake fluid damages paint & plastics. Protect bodywork and clean spills immediately.
- This FM2 Foreman has a single master cylinder feeding the front & rear circuits; bleed the farthest wheel from the master cylinder first to the nearest.
- The TRX500 Foreman PS uses conventional hydraulic calipers; there is no factory ABS to complicate bleeding.
- Power steering on this model is a separate hydraulic system — do not mix power steering fluid with brake fluid and avoid contaminating the PS reservoir during work.
- Replace reservoir cap seal if cracked and inspect rubber brake lines for swelling or cracks; replace any suspect lines before bleeding.
Preparation
- Park on level ground, set the parking brake, and disconnect the battery negative terminal if you plan to remove electrical loads or work near wiring.
- Clean the area around the brake fluid reservoir cap to prevent contamination when opened.
- Remove wheel covers or wheels if easier access to bleeder screws is needed. Support the ATV securely on stands if wheels are off.
- Open reservoir, remove diaphragm and cap, and top to the MAX line with clean DOT 3 fluid. Keep the reservoir topped during the entire procedure.
Bleeding sequence
Identify which wheel is farthest from the master cylinder and start there. Typical sequence for TRX500: rear passenger-side, rear driver-side, front passenger-side, front driver-side. If uncertain, use the visual routing of lines to confirm.
Manual (helper) method
- Attach clear tubing to the bleeder nipple and submerge the other end in a small amount of brake fluid in a catch bottle to prevent air re-entry.
- Have a helper slowly depress the brake pedal (or squeeze the lever) several times and hold it down.
- Open the bleeder screw one-quarter to one-half turn to let fluid & air escape. Close the screw before the pedal/lever is released. Repeat until no air bubbles appear and fluid runs clear.
- Top up the reservoir frequently; never allow it to go below the MIN mark while bleeding.
- Proceed to the next wheel in the sequence.
Vacuum or pressure bleeder method
- If using a vacuum pump, attach clear tubing to the bleeder nipple and pump until clear fluid with no air bubbles flows. Monitor reservoir level — top up as needed.
- If using a pressure bleeder, pressurize the master cylinder reservoir per tool instructions and open each bleeder in sequence until clear fluid flows with no bubbles.
Bench checks & final steps
- After bleeding all corners, check pedal/lever firmness: it should be firm and not spongy. If still soft, repeat bleeding or inspect master cylinder, calipers, hoses & wheel cylinders for leaks or internal failure.
- Clean bleeder screws and torque to factory or snug specification; avoid over-tightening. Wipe down any spilled fluid and re-install reservoir diaphragm & cap.
- Dispose of old brake fluid responsibly at an approved recycling facility.
- Road-test at low speed in a safe area to confirm braking performance; check for leaks and re-check reservoir level after test ride.
Troubleshooting
- Persistent sponginess after repeated bleeding: suspect collapsed rubber lines, a faulty master cylinder, or air trapped in a caliper piston. Inspect and replace components as needed.
- Leaking bleeder screw or caliper: replace hardware or caliper seals before re-bleeding.
- If fluid turns dark quickly, pads or rotors may be contaminated or calipers are deteriorating — inspect and service braking components.
Model-specific maintenance tips for the TRX500 FM2
- Inspect front and rear caliper mounting bolts and slider pins for corrosion; clean and lubricate with high-temp brake grease where required.
- Due to power steering use and heavier-duty riding, check brake pad wear more frequently if you tow or carry loads.
- The TRX500's brake reservoir sits exposed to vibration; ensure the cap seal is in good condition to prevent contamination and moisture ingress.
- Replace brake fluid every 1-2 years, or sooner if used in wet/muddy conditions, to avoid moisture-related brake fade and corrosion in the system.
Follow this MotoSport proprietary procedure to keep your TRX500 Foreman stopping reliably. If you encounter seized bleeder screws, badly corroded lines, or a failing master cylinder, replace those parts before finishing the bleed for a safe, long-lasting repair.
