This MotoSport-exclusive guide shows step-by-step how to properly replace and bleed the brake fluid on a 2005 Honda TRX250 RECON ES. Follow these instructions carefully to maintain braking performance and safety. Read through the whole procedure before starting and have the correct tools and fluid on hand.
Tools & supplies
- New brake fluid (see owner's manual for DOT 3 or DOT 4 recommendation)
- Clear vinyl tubing that fits firmly over bleeder nipples
- Catch bottle for old fluid
- Wrenches for bleeder nipples (typically 8mm or 10mm)
- Turkey baster or fluid-transfer syringe (optional)
- Clean rags and brake cleaner
- Jack or stands to lift the ATV safely
- Safety glasses and nitrile gloves
Model notes for the 2005 TRX250 RECON ES
- The 2005 Recon ES is a compact utility ATV with simple, non-ABS hydraulic braking. Verify the DOT rating in the owner's manual before buying fluid; Honda often specifies DOT 3 or DOT 4. Do not mix glycol-based DOT fluid with silicone-based fluids.
- Check brake reservoir locations before beginning. The front/rear reservoir configuration may be compact; remove plastics as needed for access. Keep the reservoir cap and diaphragm clean to avoid contamination.
- Inspect rubber brake lines, caliper boots, master cylinder seal and parking-brake mechanism for wear and corrosion while draining; these ATVs are often used in mud and moisture, which accelerates hose and hardware deterioration.
- Battery and electric-start components on the ES model are near the front; avoid spilling fluid on electrical parts and clean any spills immediately.
Preparation
- Work on a level surface. Secure the ATV with the parking brake engaged and wheel chocks if needed. If lifting a wheel, support the ATV on sturdy stands.
- Remove reservoir cap(s) and diaphragm. Clean around the cap to avoid contamination. Use a turkey baster or syringe to remove most old fluid from the reservoir to minimize dripping when you open lines.
- Open new brake fluid and keep it sealed until use. Do not let new fluid sit open to air for long; it absorbs moisture.
Basic flushing & bleeding procedure
Perform this procedure for each brake circuit. If your TRX250 has separate front and rear circuits, do front first then rear, or follow the sequence in the owner's manual. The concise method below is a reliable single-person or two-person approach.
One-person method with tube and catch bottle
- Fill the reservoir to the MAX mark with fresh fluid. Keep the cap loosely in place to reduce contamination but allow air escape.
- Attach clear tubing to the bleeder nipple on the caliper or wheel cylinder and place the other end into a catch bottle partially filled with a little fresh fluid to prevent air being drawn back in.
- Loosen the bleeder nipple one turn. With the reservoir full, slowly squeeze the brake lever or pedal until resistance rises. Hold pressure, then while holding, open the bleeder nipple briefly to let fluid and air escape into the tubing. Close the nipple before releasing the lever/pedal. Repeat.
- Monitor the reservoir level closely. Refill as needed to prevent the master cylinder from drawing air.
- Continue pumping and opening/closing the bleeder until clear, bubble-free fluid comes out and lever/pedal feel is firm. Tighten the bleeder nipple to spec (snug; do not over-torque).
- Wipe any spilled fluid immediately. Repeat for the other side or other circuit as required.
Two-person method
- Person A holds steady pressure on the lever/pedal. Person B opens the bleeder briefly to expel fluid and closes it before the lever/pedal is released. Refill reservoir as needed. Repeat until fluid runs clear and no air appears.
Final steps
- Top off the reservoir to the MAX mark, reinstall and tighten the cap with a clean diaphragm in place.
- Clean all fittings and surrounding areas with brake cleaner. Inspect for leaks while applying pressure to the brake lever/pedal and while moving suspension through travel.
- Properly dispose of old brake fluid; do not pour it down drains or into the environment.
- Test ride at low speed in a safe area to confirm firm braking and correct operation before returning to regular use.
Tips & common issues specific to the Recon
- Because Recon ATVs are frequently trail-used, check caliper slides, pistons and parking-brake components for corrosion. Replace seized slide pins or worn seals during a fluid change.
- If you notice a soft or spongey lever after bleeding, repeat the bleed procedure and inspect master cylinder pushrod free play and pedal linkage for wear or misadjustment.
- Old rubber hoses on older Recon models can be internal-collapsed and may pass air or restrict return flow. Replace hoses if you observe spongy feel despite correct bleeding.
- Keep electrical components and battery terminals covered while working; brake fluid can be mildly corrosive to painted/electrical surfaces.
When to seek professional help
Hire a technician if you see persistent leaks, warped rotors, frozen calipers, or if bleeding does not restore firm brake feel. Brake-system work affects safetyif you are unsure, let a pro inspect and certify the job.
Following this MotoSport procedure will keep your 2005 Honda TRX250 RECON ES braking reliably and help you spot model-specific wear items before they become failures.
