This stepbystep MotoSport guide covers full brake fluid replacement and bleeding for the 2017 Honda TRX500 Foreman 4X4 ES POWER STEERING (FE2). Follow all shopsafety practices: work on a cool machine, secure the ATV on level ground, wear eye protection and gloves, and keep brake fluid off painted surfaces (it damages paint).
What you need
- Fresh brake fluid per the owner's manual (use the specified DOT rating; if unsure, consult the manual before starting)
- Bleeder kit or clear tubing & container
- Brake cleaner, shop rags, and catch pan
- 10 mm wrench (bleeder), appropriate sockets for reservoir cap and caliper hardware
- Turkey baster or syringe for removing old fluid from master cylinder reservoir
- Assistant (recommended) or pressure/vacuum bleeder
- Torque wrench for caliper bolts if removed
Model notes specific to the 2017 TRX500 Foreman FE2
- The TRX500 FE2 features front hydraulic discs and a rear hydraulic brake system; some versions use an internal parking brake mechanismconfirm which rear setup your unit has before starting.
- Power steering is electric assist — it does not use brake fluid, but when working near the steering rack and wiring harness take extra care to avoid contamination or damage.
- The master cylinder reservoir is plastic and mounted on the handlebar; avoid overfilling. Cap and diaphragm must be reinstalled cleanly to prevent moisture ingress.
- If your machine has been sitting for long periods, inspect rubber hoses and caliper boots for cracking; replace any suspect components before bleeding to avoid introducing air from leaky lines.
Preparation
- Park ATV on level surface, engage parking brake (if present) and block wheels.
- Clean around the master cylinder reservoir cap to prevent dirt entering the system.
- Remove the reservoir cap and diaphragm; use turkey baster to remove old fluid until level is low but not empty.
- Top reservoir with fresh fluid to the specified level. Keep cap loose during bleeding to allow air to escape.
Bleeding order
Follow this wheel sequence for most Honda ATVs: start with the caliper furthest from the master cylinder and finish with the closest. For the TRX500 FE2 common order is: right rear, left rear, right front, left front. Confirm routing on your machine and adjust sequence if plumbing differs.
Pistonbypiston manual bleeding (with assistant)
- Attach clear tubing to the bleeder nipple and place other end in a container partially filled with fresh fluid to prevent drawing air back in.
- Have your assistant sit on the seat and slowly apply steady pressure to the brake lever/pedal; do not pump rapidly.
- Open bleeder screw ~1/4 turn with wrench; fluid and air will flow into the tubing. Close the screw before the assistant releases the lever/pedal to avoid sucking air back in.
- Repeat at that caliper until only clean fluid with no bubbles appears, then tighten bleed screw to spec handtight plus a small additional turn (do not overtighten).
- Check and top the reservoir frequently so it never runs dry.
- Repeat for each wheel following the specified order.
Pressure or vacuum bleeder method
- Attach the bleeder tool to the reservoir or bleeder nipple per the tool instructions.
- Operate tool to draw/pressure fluid through the system while opening each bleeder nipple briefly until fluid runs clear and bubblefree.
- Keep reservoir topped and follow the same caliper sequence.
Finishing steps
- Top the reservoir to the max mark, reinstall diaphragm and cap securely.
- Wipe all connections and inspect bleed screws and hose fittings for leaks.
- Cycle the brake lever/pedal several times to confirm firm feel. If soft or spongy, repeat bleeding steps.
- Torque any removed caliper or line fittings to factory specs. Clean any spilled fluid and touch up paint if needed.
- Test ride at low speed in a safe area to verify proper braking performance before normal use.
Troubleshooting
- Persistent spongy pedal after thorough bleeding may indicate internal master cylinder or caliper seal failure — inspect and rebuild or replace as needed.
- If you see frequent air return, check all hose connections and banjo bolts for leaks, and inspect flexible hoses for porosity.
- Contaminated or dark fluid after a full replacement suggests system corrosion or old rubber breakdown; consider replacing hoses, seals or calipers if contamination recurs.
Maintenance tips
- Brake fluid is hygroscopic; replace every 1-2 years or per the owner's manual to prevent corrosion and reduced boiling point.
- Store brake fluid in original sealed container; do not reuse drained fluid.
- When replacing hoses or components, use OEM or equivalent quality parts to maintain system reliability and safety.
Follow this MotoSport procedure to keep your TRX500 FE2 braking system safe and responsive. If you encounter major leaks, damaged components, or difficulty achieving a firm brake feel, stop and consult a qualified technician or your owner's manual for modelspecific service limits.
