I have a 1958 Cloud. Brakes are still more than a comparable car of that era, however, they still have a simple enough system. Just not the typical set up. The brakes are servo driven power brakes. The servo is powered off the transmission. There are 2 master cylinders and two brake fluid reserviors. The brake pedal engages the servo which provides power to the 2 master cylinders which each work one front and one back brake. There is also a mechanical link if that goes out. So there is in effect a tripple system. Its all in knowing how it all works. After that its not complicated. The brake servo should be serviced every 2 yrs. When set up right they have great brakes.
Hope this helps.
