Brake Master Cylinder for Kawasaki Mule and Teryx - Reliable OEM Fit

In this review the focus is on a direct-fit replacement brake master cylinder intended for a wide range of Kawasaki Mule and Teryx side-by-side models. The bottom line: this assembly is for owners who need a straightforward, OEM-spec replacement that restores braking performance without a lot of modification. The reviewer found it to be a complete unit with reservoir and banjo bolt included, easy to install, and built to deliver consistent pressure and service life where original part numbers 43015-1683, 43015-1682, and 43015-1551 are required.

Key Features

• Complete assembly: Ships as a full brake master cylinder with reservoir and banjo bolt, so there is no need to source extra parts before installation.
• Wide fitment: Covers many Kawasaki Mule and Teryx models from older KAF300 units through recent KAF620 and KRT/KRF Teryx series, making it useful for fleet or multi-year maintenance.
• OEM specification: Manufactured to match the referenced Kawasaki part numbers so it integrates with existing brake lines and fittings without modification.
• Durable construction: Built from advanced materials and precision manufacture to maintain sufficient hydraulic pressure and extend working life compared with worn originals.
• Easy installation: The design and included hardware reduce labor time during replacement, which is helpful for DIY installers and mechanics alike.

Who It's For

This master cylinder is aimed at owners and technicians who need an accurate replacement for specific Kawasaki part numbers and want a drop-in repair for Mule 500/520/550, Mule 600/610/SX, Mule 1000, many Mule 2500/3000/4000 series machines, and Teryx 750/800 models. It suits both DIYers comfortable bleeding brakes and shops that prefer a ready-to-fit assembly.

It is not for owners of Mule PRO KAF820/KAF1000 or the Teryx KRX 1000 KRF1000 Edition, which are explicitly incompatible; those machines require different master cylinder designs and fittings.
