Rear disc brake master cylinder with oil reservoir, compatible with the hydraulic brake system upgrade kit for ATVs/UTVs

Integrated Rear Disc Brake Solution: This product is a complete, foot-operated hydraulic rear disc brake system. Key components include the master cylinder (with reservoir), rear caliper, brake disc, brake lines, and mounting hardware. It provides a complete solution for upgrading or replacing brakes – from actuation to braking. Optimized for Rear Braking: The master cylinder is specifically tuned for the rear braking requirements of ATVs/UTVs, providing the correct hydraulic ratio and stroke. This ensures sufficient and controllable braking force at the rear wheel and is particularly well-suited for situations requiring stable rear braking, such as... For example, pulling heavy loads, towing trailers, or driving downhill. Drum to disc brake conversion or direct replacement: This product is an ideal kit for converting original rear drum brakes to disc brakes and can also be used for a complete replacement of older rear disc brake systems. It significantly improves braking performance, heat dissipation, and water and mud resistance, and simplifies maintenance. Ready-to-use kit: All components are pre-assembled for optimal compatibility and designed to simplify the complex conversion process. This allows users to perform a complete brake system upgrade relatively easily.
