This MotoSport guide walks you through a safe, effective brake fluid change and bleed procedure for the 1995 Honda TRX300FW 4X4. The instructions are written for the confident DIYer with basic tools. Read each step fully before starting and follow all safety notes.
What you need
- Correct brake fluid: DOT 3 is recommended for this MMY unless your owner’s manual specifies otherwise
- Clear plastic tubing that fits snugly over bleed nipples
- Clean catch bottle and fresh rags
- Brake fluid syringe or turkey baster for reservoir cleaning
- Box end wrenches (usually 8mm or 10mm for bleed nipples) & small adjustable wrench
- Brake cleaner and small wire brush
- Floor jack or ramps and jack stands to safely support the ATV if wheels are removed
- Protective gloves & eye protection
Model notes specific to the 1995 Honda TRX300FW 4X4
- The TRX300FW uses a conventional hydraulic brake system with a handlebar master cylinder for front brakes and a separate rear master cylinder/hydraulic circuit for the rear brake. Treat each circuit independently when bleeding.
- Brake reservoirs on these machines are plastic and age with time &mdash keep contamination out and replace a cracked reservoir cap or seal before adding fluid.
- Some original fittings are small and can round easily. Use the correct wrench size and avoid excessive force.
- Bleed nipples and rubber hoses may be corroded or swollen on older machines &mdash inspect and replace any worn hoses or corroded nipples before bleeding.
Preparation
- Work on a level surface with the engine off and key removed. Set the parking brake if available and block wheels to prevent movement.
- Clean around the master cylinder reservoir caps and bleed nipples with brake cleaner to prevent dirt from entering the system.
- Raise the wheels that you will bleed so calipers/wheel cylinders are accessible. Support the ATV securely with jack stands.
- Remove enough old fluid from the reservoir to make room for fresh fluid, then top to the max mark with fresh DOT 3 fluid. Keep the cap loosely threaded to avoid contamination but minimize exposure to air.
Bleeding order
Use the standard farthest-to-nearest sequence from the master cylinder. For the TRX300FW that typically means:
- Rear wheel farthest from master cylinder
- Rear wheel nearest master cylinder
- Front right
- Front left
If your machine layout differs, always start with the wheel farthest from the reservoir and finish nearest the master cylinder.
Step-by-step bleed (single-person method)
- Fit clear tubing over the bleed nipple and submerge the other end in a bottle partially filled with clean fluid to prevent air re-entry.
- With the nipple closed, have someone (or use a brake pedal depressor) slowly pump the brake lever/pedal several times and hold it against the stop. If working alone, firmly hold the lever/pedal in the applied position with a clamp or strap designed for that purpose.
- Open the bleed nipple about a quarter turn to let fluid and air escape; watch the tubing and close the nipple before the lever/pedal reaches the released position.
- Top off the reservoir immediately to avoid introducing air. Repeat pump-hold-open-close until fluid leaving the nipple is clean and free of bubbles.
- Once clear, tighten the nipple to specified snugness (avoid over-torquing), wipe clean, and move to the next wheel following the bleed order.
- After all corners are bled, ensure the reservoir is filled to the correct level and securely cap it. Pump the lever/pedal to confirm a firm feel. If sponginess remains, repeat bleeding on the affected circuit.
Flush & full fluid replacement
To replace all fluid, repeatedly draw out old fluid from the reservoir with a syringe or turkey baster and refill with fresh DOT 3, then bleed each circuit until only clear fluid exits the bleed nipples. Work progressively so the system is never allowed to run low on fluid.
Post-bleed checks & tips
- Inspect brake lines, hoses, fittings, and calipers/wheel cylinders for leaks while applying pressure to the system.
- Ride slowly and test brakes in a safe area before returning to normal operation. Strong, consistent lever/pedal feel is the goal.
- Dispose of used brake fluid properly &mdash it’s toxic and absorbs moisture.
- If the system remains soft after multiple bleeding attempts, inspect master cylinder seals, caliper pistons, and flex hoses for internal collapse. Replace components as needed.
- Replace old rubber hoses and cracked lines common on 1995 machines to maintain braking performance and safety.
Troubleshooting
- Persistent air: check reservoir cap vent and seals, ensure clamps are not letting air into the system, and inspect for leaks that allow air ingress.
- Soft pedal/lever after bleeding: likely internal seal wear in master cylinder or collapsed hose &mdash bench-test or replace suspect parts.
- Brake drag after bleed: ensure calipers/wheel cylinders move freely and pistons retract properly; check for corroded hardware.
Final notes
Routine brake fluid replacement every 1-2 years prevents moisture buildup and corrosion in brake components. For the 1995 Honda TRX300FW 4X4 specifically, pay attention to aged reservoirs, small fittings that seize, and the dual-circuit layout. Keep your MotoSport parts search handy if you need replacement hoses, nipples, or master cylinder components for this MMY.
