This guide is MotoSport's step-by-step procedure for flushing and replacing the brake fluid on a 2013 Honda Rancher 420 4X4 ES (FE1). Follow these instructions carefully to maintain braking performance and corrosion protection. Work on a cool, level surface and use clean tools and new fluid. This procedure assumes the Rancher has conventional hydraulic brakes without ABS.
What you'll need
- DOT 3 or DOT 4 brake fluid (Honda permits DOT 3; DOT 4 offers higher boiling point) new, sealed bottle
- Clear plastic tubing sized to fit bleed nipples
- Catch container for old fluid
- Wrenches for bleed nipple (usually 8mm or 10mm)
- Phillips and flat screwdrivers
- Clean rags & nitrile gloves
- Turkey baster or fluid turkey pump (optional) to remove old fluid from master cylinder reservoir
- Jack and stands or ramps to raise wheels (if wheel removal is desired)
- Brake cleaner
Model notes — what Rancher 420 FE1 owners should know
- The 2013 Rancher 420 4X4 ES uses a simple hydraulic brake systemno factory ABSso bleeding is conventional at the calipers/drum bleeder.
- Reservoir(s) are located on the handlebar/master cylinder for the front and near the rear brake pedal/master for the rear; keep reservoirs capped and clean to avoid contamination.
- Honda approves DOT 3 brake fluid; many owners prefer DOT 4 for improved heat resistance. Do not mix DOT 5 (silicone) with DOT 3/4.
- Brake components on this model are exposed to mud & water; after off-road use inspect hoses, bleed nipples & calipers for corrosion before bleeding.
- Replace rubber hoses if they are cracked, swollen or soft; old rubber can allow moisture ingress and reduce system integrity.
Preparation
- Park on level ground, set parking brake, and remove ignition key.
- Wear gloves and eye protection. Keep rags handy to immediately wipe spilled fluid; brake fluid damages painted surfaces.
- Clean around the master cylinder reservoir cap(s) before opening to prevent dirt falling in.
- If the wheels are heavily soiled, rinse and dry around calipers and bleed nipples.
Step-by-step: Full flush and bleed
Bleed in this recommended sequence: front right, front left, then rear. If your Rancher has a combined master cylinder setup, follow the same logic from near to far wheel. One person is ideal — a helper to operate the brake lever pedal while you open/close bleed nipples. If solo, use a one-way bleed tool or vacuum pump.
- Remove old fluid from reservoir
- Open reservoir cap(s) and use a turkey baster or siphon to remove most old fluid. Do not let debris fall in.
- Wipe the inside lip clean and inspect fluid color. Dark fluid indicates water/contamination; proceed to full flush.
- Top up with new fluid
- Pour new DOT 3 or DOT 4 fluid into the reservoir to the fill line. Keep cap off but tilt container so it does not spill into open reservoir.
- Prepare bleed fittings
- Fit clear tubing onto the caliper bleed nipple; place other end in a catch jar partially filled with fresh fluid to avoid drawing air back in.
- Loosen the nipple about a quarter to half turn; do not remove it.
- Bleed each caliper
- Helper pumps the brake lever/pedal slowly 3–5 times and then holds pressure.
- While pressure is held, you briefly open the bleed nipple to let fluid and air escape, then close the nipple before the helper releases pressure. Repeat until clear, bubble-free fluid runs into the tubing.
- After each cycle, top up the master reservoir so it never runs low. Running the reservoir dry will introduce air into the system.
- Tighten the bleed nipple to snug after bleeding, but avoid over-torquing. If unsure, tighten to a firm feel and check for leaks.
- Bleed sequence
- Front right caliper first, then front left, then rear. This pushes fresh fluid through the farthest points last and avoids trapping air.
- If your unit has dual reservoirs, repeat the process for each circuit, keeping reservoirs topped.
- Bench-bleed master cylinder (if removed)
- If you remove the master cylinder for servicing, bench-bleed it before reinstalling to remove internal air.
- Final checks
- Close reservoirs and clean any spilled fluid. Wipe all components with brake cleaner if needed.
- Operate the brake lever and pedal several times. Brake feel should be firm and not spongy. If soft, repeat bleeding until firm.
- Inspect hoses, fittings and bleed nipples for leaks while holding pressure.
- Test the ATV at low speed in a safe area to confirm braking performance before full use.
Disposal & maintenance tips
- Dispose of old brake fluid according to local hazardous-waste rules.
- Bleed brakes every 1–2 years or sooner if you notice softness, poor stopping, or contamination. Frequent wet/off-road use can accelerate fluid degradation.
- Keep replacement fluid sealed and store away from moisture; brake fluid is hygroscopic and absorbs water over time.
- If any component shows heavy corrosion, stickiness, or damage, replace it rather than attempting a patch repair.
Troubleshooting
- Persistent spongy pedal after multiple bleeds: inspect for a leaking flexible hose, damaged master cylinder, or internal caliper leak.
- Brake drag after bleeding: ensure bleed nipple is fully closed and caliper slide pins move freely; check for overfilled reservoir or stuck pistons.
- If you suspect internal master cylinder problems, remove & inspect or replace it and bench-bleed before reinstalling.
Performing a proper flush and bleed restores braking reliability and reduces the risk of moisture-related failure. If you're not comfortable doing this service, MotoSport recommends professional brake service for safety-critical systems.
