I believe it may be part of the accessory "No Roll" device. Another name some used was "Hill-Holder". If so, there would also be some linkage (or at least some remnants of some) to the clutch pedal.

Operation was once you were on a hill and brakes were applied, gravity would cause a small ball inside the device to roll back and block the fluid from returning to the master. That would keep the brakes applied. Once you started engaging the clutch to move the car, the linkage would move the ball away so brake fluid could return and brakes release.
