TEXT: We wish to request clarification of our interpretation of S5.4.1, Master Cylinder Reservoirs, of FMVSS No. 105-75, (105a) published in the Federal Register on May 18, 1973.

S.5.4.1 reads as follows:

Master Cylinder Reservoirs.

A master cylinder shall have a reservoir compartment for each service brake subsystem serviced by the master cylinder. Loss of fluid from one compartment shall not result in a complete loss of brake fluid from another compartment.

As we understand it, this Section does not prohibit the designs sketched below.
