Replacement Avanti Master Cylinders

NOTE: The larger reservoir is plumbed to the Disk brakes)

Note the bore sizes. With a booster, over a 1.0" bore is very workable. Less than a 1.0" bore might give more pedal throw than desired. NO power booster with over a 1.0" bore might require extra pedal effort.
