Replacement cap for early diagonal split type master cylinders. These had very large reserviors and were fitted with this big cap. These were found on certain export market cars like the Innocenti Minis, Austin Americas, and some Canadian Minis. These master cylinders are not reproduced, so this rebuild kit is your only option.
