Rear Brake Master Cylinder Pump For Kawasaki KZ1000 Versys 1000

Rear Brake Master Cylinder Pump for Kawasaki

This rear brake master cylinder pump is a direct replacement hydraulic component that pressurizes brake fluid to operate the rear caliper, and it cross-references common Kawasaki rear master cylinder part numbers used across several models.

Overview

This rear brake master cylinder pump for Kawasaki gives you a fresh hydraulic actuator for the rear braking circuit, converting pedal travel into fluid pressure at the caliper. It is built for riders and mechanics replacing a leaking, seized, or rebuild-worn master cylinder on Kawasaki sport and standard motorcycles. The rear brake master cylinder fits a range of models, making it a practical spare for garage stock.

Specs At A Glance

Good To Know

Q: Will this work as a bolt-on replacement? A: It is designed to match the rear master cylinder mounting and hydraulic layout of the listed Kawasaki models, but always compare the mounting holes, outlet angle, and rod length before installing. Q: Do I need to bleed the brakes after fitting? A: Yes. Any time a rear master cylinder is replaced, the rear brake circuit must be fully bled to remove air and restore firm pedal response.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
