This 1992 Bentley Mulsanne S is an interesting car we had in. It is equipped with a 6.75L V8 Engine using a mechanical style fuel injection system and a GM TH400 transmission.
The hydraulic brake system is continually circulating/self bleeding and uses a very specific mineral oil plus.
In addition to the hydraulic brakes, the parking brake utilizes a number of levers and rods to apply. This is a very complicated set up in comparison to modern day vehicles.
