Brake Fluid Reservoir Question

W123, W126, R107 and certain other chassis from the 1980s were equipped with brake fluid reservoirs that had two depressable black rubber "caps", one for each brake circuit fluid chamber.

What was the function of these "caps" and why were they eventually eliminated?
