How to Bleed and Replace Brake Fluid on a 2013 Honda TRX250 RECON ES

Shop parts for a 2013 Honda TRX250 RECON ES ATV.

This MotoSport guide walks you through a safe, complete brake fluid change and bleed on the 2013 Honda TRX250 RECON ES. Follow these steps carefully and inspect parts as you go. Use DOT 3 brake fluid unless your service manual specifies otherwise.

Tools & Supplies

  • DOT 3 brake fluid (fresh, unopened)
  • Clear plastic tubing and a clean catch bottle
  • Wrench set (bleeder nipple size typically 8 mm or 10 mm)
  • Brake bleeder kit or hand pump (optional)
  • Turkey baster or fluid syringe (to remove old fluid)
  • Clean rags, gloves, eye protection
  • Jack or stand to lift wheels for access

Model Notes for the TRX250 RECON ES

  • Brake reservoir location: the master cylinder reservoir is on the handlebars; some RECON models have an additional rear master cylinder on the frame. Confirm which applies to your unit before starting.
  • The RECON ES uses a simple hydraulic system without ABS; bleeding follows the standard master-to-wheel sequence.
  • Inspect brake lines and hoses for cracking or soft spots common on older ATVs; replace any suspect hoses before bleeding.
  • Use only new DOT 3 fluid and never mix with used fluid or contaminated containers; DOT fluids absorb moisture over time so replace every 1-2 years depending on use.

Preparation

  • Park the ATV on level ground, engage parking brake or secure wheels, and remove the key.
  • Clean around the master cylinder cap and bleeder nipples to prevent contamination.
  • Raise the wheels if necessary so calipers/adjusters are accessible and to keep fluid moving through system.
  • Protect painted surfaces from spilled fluid; brake fluid damages paint.

Fluid Replacement & Bleed Sequence

  1. Remove old fluid from the reservoir using a turkey baster or syringe until mostly empty. Wipe clean around cap. Refill reservoir with fresh DOT 3 fluid to the full mark but do not overfill.
  2. Identify bleed order. On the TRX250 RECON ES bleed from the wheel farthest from the master cylinder first, then move progressively closer. For most handlebar-mounted master cylinders that means: rear wheel(s) first, then front wheel(s). If you have two separate systems (front/rear master cylinders), treat them independently.
  3. Attach clear tubing to the bleeder nipple and submerge the other end in a small bottle partially filled with clean brake fluid to avoid air re-entry.
  4. Have an assistant slowly depress the brake lever/pedal several times and hold it down. Open the bleeder nipple one quarter to one half turn until fluid and air bubbles flow into the tubing. Close the nipple before the assistant releases the lever/pedal. Repeat until no bubbles appear and fluid runs clear. Keep the reservoir topped off during the process to prevent air from being drawn into the master cylinder.
  5. Work through each wheel in the correct order, ensuring reservoir level stays within marks. If fluid becomes dark quickly, consider a second full reservoir flush: drain reservoir, refill with fresh fluid, then repeat bleeding sequence.
  6. After all wheels are bled and no air remains, tighten bleeder nipples to the correct snugness (hand tools only; avoid excessive torque). Wipe fittings clean and top reservoir to the full mark. Reinstall and secure the master cylinder cap.
  7. Dry test: pump the brake lever/pedal several times to confirm firm feel. If the lever is spongy, repeat bleeding until firm. Do not ride until brakes feel solid and consistent.

Final Checks

  • Inspect for leaks at bleeder nipples, hose connections, calipers, and master cylinder.
  • Check brake pad/drum wear and replace if below specification; worn components can hide bleeding or performance issues.
  • Dispose of old fluid properly; do not pour on the ground or into drains.
  • Perform a slow test ride in a safe area to verify stopping performance before returning to normal use.

Additional MotoSport Tips

  • Keep a spare master cylinder cap seal and bleeder nipple washers on hand for older RECON units where rubber parts may be brittle.
  • If you encounter persistent air or contaminated fluid that won't clear, inspect internal components for a failing master cylinder or collapsed hose; replacement may be required.
  • Document the date and mileage when fluid was changed; routine replacement every 12-24 months keeps hydraulic components healthy.
