082054335 Old style round reservoir ~12mm hand master cylinder. This master cylinder will operate a single F08 (or F05) brake caliper and is a standard replacement for '70s and '80s models (T3, G5, 850 LeMans, LeMans II, CX100, SP1000, LeMans III, California II, Convert, etc) with the Moto Guzzi integrated braking system. Also is a nice update for single disk brake Eldorado or 850T models, providing a much better hydraulic ratio for improved braking with less lever effort.
Note: Use only DOT3 brake fluid
