Key Features & Benefits – EPMAN 0.700" (17.78mm) 90mm master cylinder
The EPMAN 0.700" (17.78mm) 90mm master cylinder can be used in hydraulic handbrake installations and custom brake systems. Its 0.700" (17.78mm) bore and the stated 90mm size are the main parameters to match to your bracket and linkage.
Beyond the bore, fit depends on mounting points, line connections, and how the lever or pedal mechanism is arranged in your setup.
When is this useful?
It helps keep a custom brake layout consistent when you want to define master cylinder parameters early in the build. It is also relevant during conversions where you need a specific bore size and packaging dimension to align with existing components.
