Shimano BL-MT200 Disc Brake Lever Diaphragm Unit

This genuine diaphragm unit is designed to perfectly fit Shimano BL‑MT200 (and compatible BL‑MT201) hydraulic disc brake levers. It restores the integrity of the internal bladder system, ensuring correct function and safety during braking.

Essential for Proper Reservoir Function: The diaphragm serves as a flexible seal between the brake lever housing and fluid reservoir. It compensates for changing oil volume during brake pad wear and maintains pressure, which helps prevent fading and ensures consistent braking feel.

Complete Kit for Hassle-Free Replacement: The unit includes the internal diaphragm membrane, a matching cover cap and a small fixing screw. Together they provide everything you need for a quick maintenance replace-up to bring your lever back to optimal performance.

Built for Durability and Reliability: Constructed of high-quality materials compatible with Shimano's mineral oil system, the diaphragm resists wear and leakage. It maintains effectiveness even in changing temperature and pressure conditions, supporting long-term reliability.

Replacement is straightforward: pop off the lever cover, install the diaphragm and cap and secure with the screw. After reassembly, a quick bleed ensures optimal function.
