This MotoSport how-to covers a full brake-fluid drain, flush, and bleed on the 2014 Honda Rancher 420 4X4 Power Steering (FM2). Follow these steps carefully, use the correct fluid, and verify brake operation before riding.

Safety first

  • Work on a level surface, engine off, key removed, parking brake engaged and wheels chocked.
  • Use eye protection and nitrile gloves. Brake fluid is corrosive to paint and plasticsclean spills immediately.
  • Do not mix brake fluid types. Honda recommends DOT 3 or DOT 4; use one type consistently and dispose of old fluid properly.

Tools & supplies

  • DOT 3 or DOT 4 brake fluid (fresh, unopened)
  • Clear tubing and a small catch bottle
  • Wrenches to fit bleeder nipples (usually 8mm or 10mm)
  • Vacuum or pressure bleeder (recommended) or a helper for manual bleeding
  • Turkey baster or fluid syringe to remove reservoir fluid
  • Rags, brake-clean spray, and a funnel with filter
  • Service manual for torque specs and iz routing (keep nearby)

Model notes specific to the FM2 Rancher 420

  • The FM2 Rancher has power steering hardware and wiring near the front suspension; protect electrical connectors and EPS components from fluid and drips.
  • Brake lines route close to plastic bodyworkcover panels before working to prevent staining.
  • Some models use a combined master-reservoir feeding front and rear circuits; locate the reservoir on the handlebar or near the master cylinder and confirm which calipers it feeds before starting.

Overview of the procedure

The goal: fully replace contaminated or old fluid with fresh fluid and remove air from each brake line. Work from the caliper farthest from the reservoir to the closest: typically rear, then front left, then front right, but confirm on your bike by tracing the lines.

Step-by-step: drain, flush, & bleed

  1. Clean the reservoir cap area thoroughly. Remove cap and diaphragm. Use a turkey baster or syringe to remove most old fluid from the reservoirdo not contaminate the removed fluid.
  2. Refill the reservoir with fresh DOT 3 or DOT 4 fluid to the full mark. Keep the reservoir topped during the entire procedure to avoid sucking air into the master cylinder.
  3. Place a clear tube over the bleeder nipple of the caliper farthest from the reservoir. Submerge the other end in a catch bottle partially filled with fresh fluid to prevent air from being drawn back in.
  4. Open the bleeder nipple one quarter to one half turn. If using a vacuum bleeder, apply vacuum and allow old fluid and bubbles to flow until clear fluid appears. If using a pressure bleeder, pressurize the reservoir and open the bleeder until clear fluid flows. If using a helper, pump the brake lever/pedal several times, then hold pressure while a helper opens the bleeder briefly; close bleeder before release.
  5. Keep topping the master reservoir frequently so it never goes below the minimum line. Continue bleeding the caliper until the fluid running out is clear, bubble-free, and at least as clean as fresh fluid.
  6. Tighten the bleeder nipple while fluid is flowing or immediately after closing per your bleeding method. Wipe off any spilled fluid from caliper, line, and paint.
  7. Repeat steps 3-6 for each remaining caliper in order from farthest to nearest to the reservoir, always keeping the reservoir topped.
  8. After all calipers are bled, pump the brake lever/pedal several times to build firm pressure. Check reservoir fluid level and top if needed, then reinstall cap and diaphragm securely.
  9. Inspect all fittings, hoses, and banjo bolts for leaks. Tighten bolts to factory torque if available; otherwise snug securely and verify no leaks under moderate brake pressure.

Full-system flush (recommended when fluid is dark or contaminated)

  • Perform the above bleeding sequence but periodically drain and refill the reservoir with fresh fluid until the expelled fluid runs clear. A full flush often requires several reservoir refills.

Final checks & break-in

  • With the vehicle on stands and wheels off the ground, apply brakes repeatedly to confirm firm, consistent pressure and no pedal/lever sink.
  • Lower the ATV, test at slow speed in a safe area, and perform several controlled stops to bed the fresh fluid and pads.
  • Recheck fluid level after the first ride and inspect for leaks.

Common issues & troubleshooting

  • Spongy brake lever after bleeding: re-bleed following the same farthest-to-nearest order and ensure the reservoir never went dry.
  • Persistent air or soft feel: inspect for damaged hoses, loose fittings, or a leaking master cylinder; replace components as needed.
  • Contaminated surfaces: immediately rinse paint or plastic with water and mild detergent if fluid contacts bodywork.

Maintenance interval

Replace brake fluid every 1-2 years or sooner if the fluid appears dark or moisture contamination is suspected. Regular replacement keeps braking performance reliable and protects internal components.

Perform the job methodically and keep the reservoir topped at all times. If you encounter leaking components, cracked hoses, or a failing master cylinder, replace parts before returning the ATV to service.
