JAVIK Front Right Brake Master Cylinder for Kawasaki ATVs — Aluminum, Sensor-Equipped

JAVIK front right brake master cylinder is a direct-fit aluminum replacement for selected Kawasaki Bayou, Prairie, Lakota and Mojave ATV models, restoring reliable front-brake actuation and sensor compatibility.

If your Kawasaki ATV’s front brake lever feels spongy, leaks fluid, or the stock master cylinder has failed, this JAVIK assembly offers a like-for-like replacement built to OEM dimensions. It replicates the original structure, includes the fluid reservoir, switch sensor and leakproof cover, and ships as a complete front brake master cylinder assembly for straightforward installation.

Which Kawasaki models and years does this part fit?

This master cylinder fits a defined range of Kawasaki ATVs when replacing the front right unit. Confirm fitment by checking the OEM part numbers or entering your bike’s year, make and model into fitment tools before ordering.

• Bayou 300 (KLF300): 1988–1999
• Bayou 400 (KLF400): 1993–1999

How does this replacement compare to the original OEM part?

The JAVIK unit is manufactured from aluminum and engineered to match the OEM structure and mounting points for easy swap-in replacement. It includes an integrated fluid reservoir, a brake light/sensor switch, and a leakproof cover so you retain the original system functions.

• OEM-equivalent fit and mounting geometry
• Includes sensor switch and fluid reservoir for plug-and-play
• Aluminum construction for strength and corrosion resistance

What are the installation and maintenance practicalities?

Installation is straightforward for anyone familiar with basic ATV brake service: remove the old assembly, transfer any reusable fittings if needed, mount the replacement, bleed the brake system, and test operation. The product ships without an instruction manual, so have basic tools and a brake-bleeding kit on hand or consult a mechanic if uncertain.

• Comes as one complete front brake master cylinder assembly
• No instruction manual included—allow time for bleeding and testing
• Check OEM numbers 43015-1489 or 43015-1369 for confirmation

What should I check before purchasing to ensure proper fit?

To avoid delays, match your ATV’s VIN/year/make/model to the fitment list and confirm the OEM part number printed on the original master cylinder. Use the store or marketplace fitment tool (like Amazon Garage) to cross-check before ordering.

• Confirm OEM#: 43015-1489 or 43015-1369 on your current part
• Verify your ATV year and model against the fitment list above
• Inspect mounting points and brake-line connections before installation

Who this is for: This replacement is aimed at Kawasaki ATV owners, hobbyists and repair shops needing an OEM-style front right brake master cylinder for Bayou, Prairie, Lakota or Mojave models from the late 1980s through the 1990s. It suits riders who want a durable aluminum assembly with sensor compatibility, and anyone restoring or maintaining older Kawasaki ATVs who prefers a direct-fit replacement rather than a custom or remanufactured unit.
