Reliable Stopping Power: Blue Line Right Front Master Cylinder
Restore the safety and feel of your braking system with the Blue Line Right-Hand Master Cylinder & Lever Assembly. Specifically engineered for scooters, motorcycles, and ATVs with front disc brakes, this complete unit serves as a direct replacement for the factory assembly. Whether your current lever is bent from a tip-over or your master cylinder is leaking and losing pressure, this assembly provides a crisp, firm brake response for confident urban riding.
Key Features
- Universal 7/8" (22mm) Bar Fitment: Designed to bolt directly onto standard 22mm handlebars, making it compatible with a wide variety of Chinese, Taiwanese, and European-style vehicles.
- Integrated Mirror Mount: Features a built-in M8x1.25 threaded socket, allowing you to easily reinstall your right-hand mirror without additional brackets.
- Ergonomic 6.5" Lever: The 165mm cast aluminum lever is contoured for a comfortable two or three-finger pull, providing excellent modulation and leverage.
- Pre-Installed Brake Switch: Includes the mechanical brake light switch and wiring, ensuring your tail light activates instantly when the front brake is applied.

Mechanic's Note: Never mix brake fluid types. If your reservoir cap says DOT 4, stick with DOT 4. When installing a new master cylinder, you must bleed the air out of the brake line — use a vacuum brake bleeder tool to pull fluid down to the caliper and eliminate any soft, spongy spots in your lever feel.
