How to Bleed & Replace Brake Fluid on a 1999 Kawasaki Lakota 300
Shop parts for a 1999 Kawasaki Lakota 300 ATV.
This MotoSport-exclusive procedure walks you through safely draining, replacing and bleeding the hydraulic brake fluid on a 1999 Kawasaki Lakota 300 ATV (MMY). Follow these steps precisely to restore firm braking performance and protect brake system components.
What you'll need
- New brake fluid use the Kawasaki-recommended DOT type (DOT 3 or DOT 4 compatible). Never use silicone-based fluid.
- Clear tubing that fits bleeder nipples
- Catch bottle or jar and rags
- Turkey baster or fluid syringe (for reservoir cleaning)
- Wrenches to fit bleeder nipples (use correct size to avoid rounding)
- Brake cleaner and shop towels
- Jack or stands and wheel chocks
- Disposable gloves and eye protection
Safety & preparation
- Work on a level surface; secure the ATV with chocks. Disconnect the battery if you prefer to avoid accidental starting.
- Brake fluid damages paint and plastics; cover surrounding finishes and wipe any spills immediately with brake cleaner.
- Wear gloves and safety glasses. Dispose of old fluid per local hazardous-waste rules.
Model notes for the 1999 Kawasaki Lakota 300
- The Lakota 300 uses a simple ATV hydraulic brake system with a single master cylinder feeding the braking circuits. Identify the master cylinder reservoir location before bleeding.
- Age-related issues: rubber hoses and reservoir cap gaskets commonly dry-rotten on older Lakotas. Inspect lines for cracks, swelling or leaks and replace if soft or bulging.
- Brake components on this model can have light surface rust on calipers or wheel cylinders if left wet; clean and inspect sliding hardware and pistons for corrosion before reassembly.
- If the reservoir plastic is cloudy, brittle or deformed, replace it. Contaminated or inflexible reservoirs can allow air ingestion even after successful bleeding.
Overview of the procedure
The application steps are: drain & clean reservoir, add fresh fluid, open bleeder(s) and pump fluid until clear and bubble-free, then top off and test. Bleed starting at the wheel furthest from the master cylinder and finish at the closest wheel.
Step-by-step guide
- Raise the ATV so wheels to be bled can rotate freely. Secure vehicle with chocks.
- Locate the master cylinder reservoir. Clean the outside & remove the cap and diaphragm slowly to avoid spilling. Inspect fluid color & condition.
- If fluid is dark or contaminated, remove as much old fluid from the reservoir as possible with a turkey baster or syringe. Wipe the reservoir interior with a clean lint-free cloth if accessible.
- Top the reservoir with fresh brake fluid so it won't run dry during bleeding. Keep the cap loosely on to limit contamination but allow venting.
- Identify the bleed nipples on each caliper or wheel cylinder. Fit clear tubing over the nipple and route the other end into a catch bottle partially filled with fresh fluid to avoid sucking air back in.
- Start with the wheel furthest from the master cylinder. Have an assistant sit on the seat and slowly apply steady pressure to the brake lever/pedal, or use a one-person vacuum or pressure bleeder if available.
- With the lever/pedal depressed, open the bleeder nipple 1/4 to 1/2 turn until fluid and air bubbles run into the tubing. Close the nipple, then release the lever/pedal. Repeat this pump-open-close cycle until clear, bubble-free fluid emerges.
- Keep the reservoir topped with fresh fluid at all times so the pump stroke never draws air into the system.
- Proceed to the next-furthest wheel and repeat. Finish with the wheel closest to the master cylinder.
- After bleeding all circuits, tighten bleeder nipples to proper snugness (do not over-torque). Wipe any spilled fluid and reinstall the reservoir cap and diaphragm securely.
- If you used a one-person vacuum/pressure bleeder, follow its instructions and be careful not to over-pressurize the reservoir.
- Operate the brake lever/pedal several times to confirm a firm feel. Recheck fluid level and top to the "MAX" mark if applicable.
- Lower the ATV, torque wheel fasteners to spec if removed, and perform a slow low-speed brake test in a safe open area to confirm braking performance before normal riding.
Tips, common issues & troubleshooting
- If brakes remain spongy after repeated bleeding, inspect master cylinder seals, internal caliper pistons and lines for leaks or internal air paths. Old master cylinders can pull air through worn seals and may need rebuild or replacement.
- Never reuse drained brake fluid. Contaminated fluid shortens component life and reduces boiling point.
- If bleeder nipples are seized, apply penetrating oil and work gently. Replace broken or rounded nipples rather than risking damage to calipers.
- If bubbles appear continuously, there may be a leak or a cracked hose drawing in air; pressurize the system lightly and look for bubbles at connections.
- Replace rubber caps over bleeder nipples after bleeding to keep moisture out on older ATVs like the Lakota.
Maintenance schedule recommendations
- For a 1999 Lakota, plan on replacing brake fluid every 1-2 years depending on use and storage conditions to prevent moisture buildup and corrosion.
- Inspect hoses, fittings and the reservoir annually; replace any components showing age-related deterioration.
Final checks
- Confirm there are no leaks at lines, fittings or bleeder nipples. Check fluid level once more after a short test ride and re-tighten if necessary.
- Dispose of used brake fluid responsibly and clean any residue from painted surfaces immediately.
Following these MotoSport-specific steps will return crisp, reliable braking to your 1999 Kawasaki Lakota 300 and reduce the risk of brake system damage from contaminated fluid.
