This MotoSport guide walks you step-by-step through safely draining, flushing, and bleeding the hydraulic brakes on a 1997 Kawasaki Lakota 300. Follow these procedures carefully to restore firm pedal feel and reliable stopping power. This procedure is written for the Lakota 300 owner who wants a thorough, repeatable serviceno shortcuts.

Safety & prep

• Work on a level surface, engine off, key removed, and wheels chocked.
• Wear nitrile gloves and eye protection. Brake fluid is corrosive to paint & plastics.
• Use a clean container for old fluid and rags for spills. Dispose of fluid per local regulations.
• Use only recommended brake fluid. For most Kawasaki ATVs of this era use DOT 3 or DOT 4 brake fluiddo not use silicone DOT 5. Check your owner's manual if unsure.

Tools & supplies

• Clear tubing that fits snugly over bleed nipple(s)
• Plastic bottle or catch jar, clean funnel
• Brake fluid (fresh DOT 3 or DOT 4 as specified)
• Bleeder wrench or correctly sized open-end wrench
• Vacuum bleeder or hand pump (optional but speeds process)
• Small screwdriver or trim tool to access reservoir cap, shop rags, jack or stands

Model notes specific to the 1997 Kawasaki Lakota 300

• The Lakota 300 has a compact master cylinder reservoir often accessed by removing a small plastic cover or seat section. Expect limited reservoir capacity – top up slowly to avoid overflow.
• Caliper bleeder nipples are exposed but may have surface corrosion from age; use care to avoid rounding the nipple hex.
• This model does not use ABS. Bleeding sequence is purely to remove air from lines and calipers; follow sequence recommended below for best results.
• Age-related rubber hoses and seals on a 1997 unit can be brittle. If you find soft, cracked, or swollen hoses, replace them before bleeding to prevent contamination and leaks.
• Brake pads and rotors on older Lakotas often need inspection for glazing or wear when fluid is changed; plan to service pads/rotors if stopping power remains poor after bleeding.

Step 1 Prepare the master cylinder reservoir

• Clean the reservoir cap area thoroughly to prevent dirt entry.
• Remove the cap and diaphragm. Siphon or absorb as much old fluid as possible from the reservoir using a clean syringe or turkey baster.
• Refill the reservoir to the "MAX" level with fresh brake fluid. Keep the cap off but diaphragm loosely in place so the system breathes while you bleed.

Step 2 Access the bleed nipple(s)

• Locate the bleed nipples on each caliper. For single-disc setups you'll have one caliper; if both front and rear are hydraulic (front/rear), plan to bleed each separately.
• Attach clear tubing to the nipple and route it into a catch bottle partially filled with a bit of fresh fluid to prevent air being drawn back into the line.

Step 3 Bleed sequence

Standard ATV sequence is: farthest caliper from master cylinder first, then closer. For many Lakota layouts bleed the rear caliper before the front; if you're unsure, bleed the caliper farthest from the master cylinder first.

• With an assistant: have them slowly pump the brake lever/pedal 3-5 times and hold pressure.
• Open the bleed nipple about 1/4 turn to let fluid and air escape into the tubing. Close the nipple before the assistant releases the lever/pedal. Repeat until clear, bubble-free fluid flows.
• Keep the reservoir topped between cycles. Never let the reservoir run dry or you will reintroduce air into the system.
• If using a vacuum bleeder or pressure bleeder: attach per tool instructions and operate until clear fluid appears at each caliper, then close nipples and remove tool.

Step 4 Repeat for each caliper

• Move to the next caliper following the bleed sequence. Continue until all lines show clear fluid and no air bubbles.

Step 5 Final checks

• Tighten all bleed nipples to specified torque if known (snug, do not strip). Wipe any spilled fluid immediately from painted surfaces & plastics.
• Top reservoir to MAX, reinstall diaphragm and cap securely.
• Operate the brake lever/pedal several times with the engine off and confirm firm, consistent pressure. If the lever feels spongy, repeat bleeding.
• Inspect around calipers, lines, and master cylinder for leaks with the system pressurized.
• Perform a slow, cautious test ride in a safe area to verify braking performance before returning to normal riding.

Troubleshooting & tips

• Persistent sponginess after thorough bleeding can indicate a collapsed hose, contaminated master cylinder, or internal caliper seal problem — inspect and replace components as needed.
• If bleeder nipples are stuck, apply penetrating oil and allow time to soak; use correct wrench size and avoid rounding the nipple.
• Do not mix mineral or silicone fluids with DOT brake fluid. Mixing destroys braking function.
• On older Lakotas consider replacing rubber lines and the master cylinder cap diaphragm if they show aging signs to prevent recontamination.

Maintenance interval recommendations

• Flush and replace brake fluid every 1-2 years for best performance and corrosion control, or sooner if you notice deterioration.
• Inspect brake hoses, pads, and rotors at the same time. Age-related wear is common on 1997 machines; replace parts showing significant wear or corrosion.

Following this MotoSport procedure will restore a firm brake lever/pedal feel and help keep your 1997 Kawasaki Lakota 300 stopping safely. If you encounter damaged or worn components beyond routine bleeding, replace them with OEM-quality parts to keep braking reliable.
